The vegetable compartment door 6 can also be pulled out toward the front direction of the paper surface in the same way. In addition, a vegetable compartment 100 (a vegetable compartment for storing items such as vegetables, see FIG. 4 ) is formed in a space constituted by the vegetable compartment door 6 and the refrigerator main body 1 .

Fig. 2 is a perspective view of the storage container pulled out from the vegetable compartment to the maximum. In addition, in the storage container 101, bottled drinks and the like are stored in addition to vegetables and the like.

As shown in FIG. 2 , in vegetable compartment 100 , inner case 124 of refrigerator main body 1 constitutes the wall surfaces of vegetable compartment 100 (left wall 100 a , right wall 100 b , bottom wall 100 c , and rear wall 100 d ). And the upper wall of the vegetable compartment 100 is comprised with the heat insulation partition wall (not shown) which partitions the vegetable compartment 100 and the freezer compartment (not shown). Therefore, in vegetable compartment 100 , the sealing property of vegetable compartment 100 is ensured by wall surfaces (left wall 100 a , right wall 100 b , bottom wall 100 c , and rear wall 100 d ), an unillustrated upper wall, and vegetable compartment door 6 .

In the vegetable compartment 100, the storage container 101 is accommodated so that it can draw out to a front side and a back side (it may be referred to as "a front-rear direction" hereafter). The storage container 101 is composed of a lower container 102 and an upper container 103 . The upper container 103 is disposed above the lower container 102 . In addition, the upper container 103 is provided with a lock handle 106 , and the user operates the lock handle 106 so that the upper container 103 can move in the front-rear direction together with the lower container 102 .

As shown in FIG. 3 , on the rear side of the vegetable compartment 100 , a machine compartment 107 for disposing a compressor (not shown) and the like outside the case is formed. In addition, cold air outlets (not shown) for cooling the inside of the lower container 102 and the upper container 103 are arranged on the rear side (back side) of the vegetable compartment 100 . Furthermore, the lower container 102 is provided with a glass partition 104 . As a result, the lower container 102 is divided into two divisions, the front and the rear. Furthermore, the upper container 103 is disposed so as to cover the space upper portion on the rear side of the two divisions of the lower container 102 .

4 and 5 are perspective views of the frame 161 supporting the storage container 101 .

In FIGS. 4 and 5 , the storage container 101 (not shown) is supported by the frame 161 so that the left and right side surfaces are sandwiched. The frame 161 is configured to include: A pair of extended left and right frame members 180; a connecting member 166 that connects the left frame member 180 and the right frame member 180 and is formed in a substantially "U"shape; Out of the accommodation mechanism) the bar-shaped cross frame 167 of each other.

Furthermore, the frame member 180 is provided with slide rails 179 for moving the storage container 101 in the front-rear direction. The slide rail 179 is fixed to the frame member 180 . The slide rail 179 draws out or accommodates the storage container 101 by expanding and contracting in the front-rear direction. Details of the structure of the slide rail 179 will be described below.

The frame members 180 provided on the left and right respectively fix the connection member 166 via the frame fixing portion 169 , and constitute the frame 161 together with the bridging frame 167 . In addition, a door fixing portion 162 for fixing the vegetable compartment door 6 is provided on the front side of the frame member 180 . The user pulls out or pushes in the vegetable compartment door 6 attached to the door fixing portion 162 from the front side, thereby pulling out the storage container 101 from the vegetable compartment 100 or storing the storage container 101 in the vegetable compartment 100 .

The connection member 166 has a bottom plate 166a supporting the bottom of the storage container 101 (not shown), and side plates 166b, 166b extending upward from the left and right ends of the bottom plate 166a along the left and right side surfaces of the storage container 101 . In this way, storage container 101 is supported by frame member 180 and connection member 166 . Furthermore, movement of the storage container 101 in the front-back direction is restricted by fitting a protrusion (not shown) formed in the flange portion 102a (see FIG. 2 ) into a hole 180m formed in the frame member 180 .

Moreover, the crossing frame 167 is attached to the back side (rear end part) of the slide rail 179 so that the slide rail 179 on either side may be connected. The inclination of the slide rail 179 is suppressed by providing the bridging frame 167 .

Fig. 6 is a perspective view showing a state in which the frame is fully pulled out from the vegetable compartment.

As shown in FIG. 6 , a container drive mechanism 200 for assisting movement of the storage container 101 in the front-rear direction is connected to the connection portion 168 (see FIGS. 4 and 5 ) provided on the frame 161 . The container drive mechanism 200 is electric, and the user applies the force required to move the storage container 101 to the front side through the connection portion 168 to the storage container 101 by pressing the open switch 201 .

The container driving mechanism 200 does not apply a force to the storage container 101 in all sections during which the storage container 101 is moving, but applies force to the storage container 101 to move to the front side only once after the user presses the open switch 201 or the like. That is, a force to the extent that the storage container 101 can be completely pulled out to the front side by the frame member 180 is applied to the storage container 101 only once. Thus, the user can easily stop the storage container 101 at a desired position while the storage container 101 is being pulled out.

Fig. 7 is a perspective view showing a state in which the frame is accommodated in the vegetable compartment. In addition, although it is not shown in FIG. 7 for simplification, frame 161 and storage container 101 are actually accommodated in vegetable compartment 100 in a state where storage container 101 is supported by frame 161 . In addition, the slide rail 179 can move along the box-side rail 178 (storage room rail, storage container pull-out storage mechanism, shown only on the left side) provided on the left and right side surfaces of the inner box 124 . Then, the slide rail 179 moves in the front-rear direction together with the frame member 180, whereby the storage container 101 is pulled out and accommodated. The detailed structure of the box-side guide rail 178 will be described below with reference to FIG. 13 .

Fig. 8 is an exploded perspective view showing a frame member and a slide rail. In addition, since the left and right frame members 180 and the left and right slide rails 179 have bilaterally symmetrical shapes (see FIG. 4 and FIG. 5 ), the following description will be made with reference to the left frame member 180 and the slide rails 179 .

As shown in FIG. 8 , the slide rail 179 is configured to include an outer member 184 , an inner member 185 , balls 188 (rotating bodies), and a cage 191 .

The outer member 184 has a side surface 184 a extending in the front-rear direction, and an upper surface 184 b and a lower surface 184 c on which the ball 188 abuts. Furthermore, the outer member 184 is formed with a stopper 184d having a shape notched toward the front end (front side) of the side surface portion 184a.

Furthermore, a connecting member 192 for attaching the frame bearing 181 (see FIGS. 4 and 5 ) and the straddle frame 167 (see FIGS. 4 and 5 ) is connected to the rear end (rear side) of the outer member 184 . At the rear end of the outer member 184, through-holes 184e into which rivets 193, 193 are inserted are formed in parallel in the front-rear direction. The rivets 193 are assumed to be, for example, what is called a blind rivet, but are not limited to rivets, and may be screwed or spot welded.

The connection member 192 is formed in a substantially rectangular shape in a side view, and is attached to the exterior member 184 so as to be disposed at a position facing the rear end 180 s of the frame member 180 . Further, through-holes 192a, 192a are formed in the coupling member 192 at positions corresponding to the through-holes 184e, 184e. In the present embodiment, the connection member 192 is attached to the outer member 184 with the highest priority given to strength, but a method in which the connection member 192 is attached to the inner member 185 conversely may also be used.

The inner member 185 has a side surface 185 a extending in the front-rear direction, which is arranged to face the outer member 184 , and an upper surface 185 b and a lower surface 185 c on which the ball 188 abuts. On the side portion 185a, a stopper 185s is formed in the vicinity of the rear end by cutting toward the outer member 184 side. Furthermore, the front end 185u of the inner member 185 is bent toward the outer member 184 side.

Further, through-holes 185d for inserting rivets 187 (container pull-out accommodation mechanism) are formed at a plurality of locations (four locations in this embodiment) at intervals in the front and rear of the side surface portion 185a. The through-holes 185d are formed at a wider interval on the front side and at a narrower interval on the rear side than on the front side.

In addition, a positioning convex portion 185e for positioning is formed between the first through hole 185d and the second through hole 185d from the front side on the side surface portion 185a. Further, on the surface of the side surface portion 185a on the side of the frame member 180, and between the second through hole 185d and the third through hole 185d, positioning protrusions 185e, 185e for positioning are formed at intervals in front and rear.

The balls 188 are held between the upper surface 184b of the outer member 184 and the upper surface 185b of the inner member 185 in a row in the front-rear direction. Further, the balls 188 are held between the lower surface portion 184c of the outer member 184 and the lower surface portion 185c of the inner member 185 in a row in the front-rear direction. Each ball 188 can move the inner member 185 and the outer member 184 independently by rotating while contacting both the inner member 185 and the outer member 184 . In addition, a roller may be used instead of the ball 188 as the rotating body.

The cage 191 holds each ball 188 rotatably, and has holes 189 a for holding each ball 188 independently up and down. Furthermore, the retainer 191 is formed to have approximately half the length of the outer member 184 in the longitudinal direction.

Slide rail 179 is configured to include inner member 185 and outer member 184 that can move independently in this way, so that the amount of pulling out storage container 101 can be ensured more. That is, first, after the inner member 185 and the outer member 184 are integrally moved to the front side, only the inner member 185 is moved to the front side from a predetermined position on the front side, thereby ensuring more draw-out amount of the storage container 101, This will be described in detail below.

The frame member 180 has: a side portion 180a extending in the front-rear direction; an upper portion 180b bent toward the inner member 185 at the upper edge of the side portion 180a; and bent toward the inner member 185 at the lower edge of the side portion 180a. The lower part 180c (refer to FIG. 5).

A through-hole 180d into which the rivet 187 is inserted is formed in the side surface portion 180a at a position corresponding to the above-mentioned through-hole 185d. In addition, a positioning concave portion (hole) 180e is formed on the side surface portion 180a at a position corresponding to the aforementioned positioning convex portion 185e.

In the slide rail 179 and the frame member 180 configured in this way, the positioning convex portion 185e is fitted and positioned in the positioning concave portion (hole) 180e. The inner member 185 is fixed (press-bonded) to the frame member 180 by inserting the rivet 187 into the through hole 180d of the frame member 180 and the through hole 185d of the inner member 185 and using a device for the rivet 187 . Thereby, the inner member 185 and the frame member 180 are fixed so that the rear end 185t of the inner member 185 and the rear end 180s of the frame member 180 become substantially the same plane. Furthermore, the outer member 184 is slidable in the front-rear direction with respect to the inner member 185 and the frame member 180 .

FIG. 9 is a side view showing an assembled frame member and a slide rail, and FIG. 10 is a sectional view taken along line A-A of FIG. 9 . In addition, in FIG. 9, illustration of the buffer member 197 mentioned later attached to the connection member 192 is abbreviate|omitted.

As shown in FIG. 9 , in the frame member 180, and at a plurality of positions (six positions in this embodiment) at the corners of the boundary between the side surface portion 180a and the lower surface portion 180c, the frame member 180 is reinforced. Rib (reinforcing portion) 180f (for improving rigidity). Furthermore, the rib portion 180 f is formed at a position rearward from the center of the frame member 180 in the front-rear direction.

In addition, the front-to-rear distance between the rearmost rib 180f and the second rib 180f from the rear is narrower than the front-to-rear distances between the other ribs 180f and 180f. In this way, by forming the rib 180f on the frame member 180, the rigidity of the frame member 180 can be improved, and the frame member 180 can be reduced due to the load of the storage container 101 when the vegetable compartment door 6 is fully opened (fully opened). Distortion of component 180 .

And, at the rear end of the lower surface portion 180c of the frame member 180, a box bearing 182 (support body, storage container pull-out accommodation mechanism, referring to FIG. 3 ) is formed to contact the pull-out action of the vegetable compartment door 6 when fully opened. Protrusion 176. In the vicinity of the protrusion 176, the above-mentioned ribs 180f, 180f are arranged close to each other.

In addition, in this embodiment, an example of rib 180f has been described as a reinforcing portion, but it is not limited to rib 180f. Regarding the plate thickness of the frame member 180, (3) other components may be mounted on the frame member 180 by spot welding, and (4) the frame member 180 may be formed separately to increase the plate thickness or material strength of the rear end side, or Combinations of the above can be employed.

As shown in FIG. 10 , an inner member 185 is fixed to the frame member 180 via rivets 187 . In addition, in FIG. 10, the rivet 187 before fixing is also shown in figure. In addition, although illustration is omitted, the rivets 187 in other locations are configured in the same manner.

The rivet 187 is formed of a hollow rivet having a cylindrical hollow portion 187a formed at the tip. After the rivet 187 is inserted into the through hole 180d of the frame member 180 and the through hole 185d of the internal member 185, the front end of the hollow portion 187a protruding from the through hole 185d is expanded so that the edge of the opening is pressed, so that the frame member 180 and the inside Member 185 engages.

However, when fixing the frame member 180 and the inner member 185 with rivets, if the rivets protrude greatly from the inner member 185 , they may come into contact with the holder 191 and the slide function of the slide guide rail 179 may not work. In addition, it is also necessary to secure connection strength when fixing the frame member 180 and the inner member 185 . That is, it is necessary to ensure strength and achieve space saving, and hollow rivets are provided in this embodiment. However, if the strength and space are sufficient, for example, they may be fixed with screws, connected by welding, or connected by riveting.

Therefore, in this embodiment, by adopting hollow rivets as rivets 187 , the amount of protrusion of rivets 187 from inner member 185 can be reduced (see FIG. 10 ), and contact between rivets 187 and retainer 191 can be prevented. In addition, since a hollow rivet is used, it can be firmly connected.

Fig. 11 is a perspective view of the components of Fig. 9 viewed from the frame bearing side.

As shown in FIG. 11 , a frame bearing 181 is rotatably supported on the right side of the coupling member 192 . The axial direction of the rotating shaft (central shaft) 181a of this frame bearing 181 faces the left-right direction. In addition, the frame bearing 181 is configured by using, for example, acetal resin for the outer ring and steel for the balls and the inner ring.

Further, the frame bearing 181 can move in the front-rear direction along the box-side guide rail 178 while rotating in the groove 189 formed in the box-side guide rail 178 . Therefore, the frame bearing 181 moves in the front-back direction while rotating, and the outer member 184 (slide rail 179 ) moves in the front-back direction.

Furthermore, a cushioning member 197 is fixed to an upper portion of the connecting member 192 via a screw 198 . The buffer member 197 is formed of synthetic resin or the like, and is configured to have: a back portion 197a positioned on the back side (rear side) of the connection member 192; an upper portion 197b positioned on the top side of the connection member 192; and a front side of the connection member 192. front portion 197c. In addition, the connection member 192 is not limited to synthetic resin, and other materials, such as rubber, may be sufficient.

Fig. 12 is a side view of the rear end of the member of Fig. 9 viewed from the frame member side.

As shown in FIG. 12, the front part 197c of the cushioning member 197 is located in the height position which opposes the upper part of the rear end 180s of the frame member 180. As shown in FIG. Thus, when the frame member 180 is closest to the connection member 192, the rear end 180s of the frame member 180 contacts the buffer member 197, thereby preventing the stopper 184d (see FIG. 8) from colliding with the front end 185u (see FIG. 8). In this way, since the buffer member 197 collides with the frame member 180, compared with the case where the stopper 184d collides with the front end 185u, collision sound (noise) and vibration can be reduced.

Fig. 13 shows the box-side guide rail located on the side of the storage room, Fig. 13(a) is a perspective view, Fig. 13(b) is a cross-sectional view along line B-B of Fig. 13(a), Fig. 13(c) is a line C-C of Fig. 13(a) Line sectional view, Fig. 13(d) is a D-D line sectional view of Fig. 13(a).

As shown in FIG. 13( a ), the box-side guide rail 178 is formed with a groove 189 that guides the frame bearing 181 (see FIG. 11 ) in the front-rear direction while rotating. On the outside of the groove 189 (the right side in FIG. 13( a )), a guide wall 190 is formed for preventing the frame bearing 181 from falling off in the middle. However, when the box side guide rail 178 is molded, it is difficult to form the guide wall 190 in the vicinity of the back side end portion 178b. Therefore, in order to prevent the frame bearing 181 from coming off from the portion without the guide wall 190 , the rib 186 for preventing the frame bearing 181 from reaching the portion without the guide wall 190 is formed. That is, on the back side (rear end) of the box-side guide rail 178, a rib 180f for restricting the movement of the frame bearing 181 that rotates inside the back side is formed. This rib 186 functions as a stopper for the frame bearing 181 .

In addition, on the front side of the groove 189, a stopper member 183 for restricting the movement of the frame bearing 181 to the front side is provided. The height (internal dimension) of the portion of the groove 189 where the stopper member 183 is mounted is low as shown in FIGS. 13( b ) and 13 ( c ). Therefore, even if the frame bearing 181 is rotatable at the portion where the stopper 183 is not attached (see FIG. 13( d )), the front movement of the frame bearing 181 is restricted by attaching the stopper 183 . Also, by restricting the movement of the frame bearing 181, the movement of the outer member 184 to which the frame bearing 181 is mounted is also restricted.

Furthermore, the stopper member 183 is a member made of synthetic resin, and is constituted as a separate member from the box-side guide rail 178 . Furthermore, claws 183a, 183a for being hooked to the case-side rail 178 are formed on the stopper member 183 at three places at intervals in the front-rear direction. As shown in FIG. 13(b), a hole 178a is formed in the case-side guide rail 178 at a position corresponding to the claw 183a. Furthermore, the claw 183a is pushed to be inserted into the hole 178a by its own elastic restoring force. Further, the front end portion (front side) of the stopper member 183 is fixed to the case-side guide rail 178 via a screw 199 . In addition, in this embodiment, an example of the case of using both the claw 183a and the screw 199 has been described, but the stopper member 183 may be fixed only by the claw 183a, or the stopper 183 may be fixed by only the screw 199. bit part 183.

Fig. 14 is a cross-sectional view showing the structure of the frame member, slide rails, and box-side rails, Fig. 15 is a cross-sectional view along line E-E of Fig. 6 , Fig. 16 is an explanatory view of the operation when the storage container is pulled out from the vegetable compartment, Fig. 16(a) Fig. 16(b) shows the case where the frame member is in contact with the box bearing when the frame bearing is in contact with the stopper member. In FIG. 14 , the front side relative to the paper corresponds to the front side of the refrigerator 10 , and the back side relative to the paper corresponds to the rear side of the refrigerator 10 . A frame bearing 181 (also refer to FIG. 11 ) attached to the back side of the outer member 184 moves in the front-rear direction while rotating in the groove 189 of the case-side guide rail 178 .

On the other hand, the outer member 184 itself provided with the frame bearing 181 is arranged outside the groove 189 of the box-side guide rail 178 , and moves in the front-rear direction together with the frame bearing 181 . That is, the slide rail 179 configured to include the outer member 184 is disposed outside the case-side rail 178 . In other words, the box-side rail 178 and the slide rail 179 are arranged separately in a cross-sectional view from the front side in a direction perpendicular to the moving direction of the storage container 101 . That is, the box-side rail 178 and the slide rail 179 are arranged so as to be shifted in the left-right direction so as not to overlap in this cross-sectional view.

Furthermore, as described above, the frame member 180 is fixed to the side surface (inner wall surface) of the inner member 185 by the rivets 187 .

As shown in FIG. 15, the lower surface part 180c of the frame member 180 contacts the box bearing 182 (support body) as mentioned above. The box bearing 182 is rotatably attached to the front end of the box side rail 178 . Therefore, when the frame member 180 moves in the front-back direction, the frame member 180 is supported by the box bearing 182 , and the box bearing 182 is rotated to move the frame member 180 in the front-back direction.

Returning to FIG. 14 , the dimension (length in the vertical direction, internal dimension) L1 of the groove 189 of the box-side rail 178 is shorter than the dimension (length in the vertical direction, external dimension) L2 of the slide rail 179 . That is, in the refrigerator 10, the slide rail 179 which has dimension L2 larger than the dimension L1 of the groove|channel 189 of the box side rail 178 is used. Therefore, it is possible to use the slide rail 179 having a sufficient dimension L2 irrespective of the dimension L1 of the groove 189 of the case-side rail 178 . Therefore, sufficient rigidity of the slide rail 179 can be ensured, and local load can be prevented from being applied to the slide rail 179 . Accordingly, when the inner member 185 is pulled out after the outer member 184 stops, a local increase in frictional force due to a local load applied to the ball 188 can be prevented, and the storage container 101 can be pulled out with a relatively light force.

In addition, among the inner member 185 and the outer member 184 constituting the slide rail 179 , the inner member 185 is fixed to the frame member 180 by a rivet 187 . That is, in a cross-sectional view from the front side in a direction perpendicular to the moving direction in which the storage container 101 moves toward the front side and the back side, the inner member 185 having a cross-sectional area smaller than that of the outer member 184 is attached to the frame. Part 180. Furthermore, the storage container 101 is supported by the frame member 180 . As a result, the moment of inertia of the area of the inner member 185 and the frame member 180 fixed to the inner member 185 increases, and the load of the storage container 101 is applied to the entire frame member 180 in a distributed manner. Therefore, generation of local large frictional force can be suppressed, and the storage container 101 can be pulled out with a smaller force.

Here, the action of each member when the storage container 101 is pulled out to the front side will be described with reference to FIGS. 14 to 16 . In addition, in each figure, the storage container 101 is not shown for simplification of illustration.

When the storage container 101 is stored in the vegetable compartment 100 (see FIG. 15 ), the slide rail 179 shrinks the most, and the rear end 180s of the frame member 180 and the connecting member 192 of the outer member 184 are in the closest state. In this way, if the storage container 101 is housed in the vegetable compartment 100 in a state where the storage container 101 is pulled out to the front side, the movement of the storage container 101 starts to move the frame member 180 and the slide guide rail 179 toward the front side. of the mobile. This force is given by the user putting his hand on the handle of the vegetable compartment door 6 (refer to FIG. 1 ) and pulling it out, or by the container drive mechanism 200 (refer to FIG. 6 ) connected to the connection part 168 (refer to FIG. ) to proceed. In addition, the application of force by the container drive mechanism 200 is performed only once at the start of the movement as described above, and the storage container 101 is pulled out to the front side using inertia thereafter.

At this time, the frictional force generated between the balls 188 constituting the slide rail 179 and the outer member 184 or the inner member 185 is relatively large. On the other hand, the friction force generated between the frame bearing 181 and the groove 189 and the friction force generated between the frame bearing 182 and the lower surface portion 180c of the frame member 180 are relatively small (see FIG. 14 ). Therefore, a relatively large frictional force generated with the movement of the inner member 185 toward the front side is also transmitted to the outer member 184 via the balls 188 . Thereby, along with the movement of the storage container 101 and the frame member 180, the slide rail 179 (external member 184) also moves to the front side (refer FIG.16(a)).

When the frame bearing 181 moves to the front side while rotating in the groove 189 of the box-side guide rail 178 , the frame bearing 181 comes into contact with the stopper 183 provided in the groove 189 as shown in FIG. 16( a ). Accordingly, the rotation of the frame bearing 181 is stopped, and the movement of the outer member 184 including the frame bearing 181 is also stopped. However, since the ball 188 (see FIG. 14 ) rotates, the inner member 185 and the frame member 180 , which can move independently of the outer member 184 , continue to move toward the front side together with the outer member 184 .

And, as shown in FIG. 16( b ), as the inner member 185 moves toward the front side, the frame member 180 fixed to the inner member 185 and the storage container 101 supported by the frame member 180 also continue to move toward the front side. At this time, the frame member 180 moves to the front side while rotating the box bearing 182 above the box bearing 182 . Therefore, if the frame member 180 moves to a predetermined position on the front side (the state in which the storage container 101 is pulled out from the vegetable compartment 100 as a whole), the protrusion 176 provided at the lower end portion of the back side of the frame member 180 as shown in FIG. 16 ( b) abuts against box bearing 182 as shown. Thus, the movement of the frame member 180 stops. Furthermore, since the movement of the frame member 180 stops, the movement of the storage container 101 also stops. This state is a fully opened state in which the storage container 101 is pulled out to the front side as much as possible.

In addition, in this embodiment, as shown in FIG. 16( b ), the distance L10 between the rear end 180 s of the frame member 180 and the connection member 192 when the outer member 184 is maximally extended is configured so that the frame bearing 181 abuts against the distance L10 . When the positioning member 183 and the protrusion 176 of the frame member 180 abut on the box bearing 182 , the distance L20 between the rear end 180 s of the frame member 180 and the connection member 192 is longer than the distance L30 . By providing the distance L30 (play) in this way, when the storage container 101 is fully opened, a strong impact is not applied to the stopper 183 from the frame bearing 181 , so that damage to the stopper 183 can be prevented. In addition, the frictional force generated between the frame bearing 181 and the groove 189, the internal dimension of the groove 189 may be narrowed in the middle, etc., so that when the storage container 101 is pulled out, the frame bearing 181 abuts against the limit position. In front of the member 183, the inner member 185 and the frame member 180 operate to be extended (pulled out).

Fig. 17 is a longitudinal sectional view when the storage container is pulled out to the front side as far as possible.

As shown in FIG. 17 , the load F of the storage container 101 is supported at two points of the box bearing 182 and the frame bearing 181 in the fully open state where the storage container 101 is completely pulled out. Furthermore, the outer member 184 is arranged between the box bearing 182 and the frame bearing 181 according to the length of the stopper member 183 in the front-rear direction. Therefore, the downward load F from the storage container 101 is supported by a part of the length of the stopper member 183 . Therefore, it is possible to prevent a large load from being locally applied to the box bearing 182 , and as a result, it is possible to reduce the force when pulling out the storage container 101 .

Furthermore, since the force when pulling out the storage container 101 can be reduced, the magnitude of the force applied by the container drive mechanism 200 (see FIG. 6 ) connected to the connection portion 168 of the frame 161 can also be reduced. Therefore, the load on the motor (not shown) constituting the container driving mechanism 200 can be reduced. In addition, since the storage container 101 is pulled out to the front side with a relatively small force, it is possible to prevent the storage container 101 from opening too much to the front side.

However, if the storage container 101 is completely opened by pulling the entire storage container 101 out of the vegetable compartment 100, when the weight of the items stored in the storage container 101 is large, due to the load F received from the storage container 101, the A force acts in an inclination direction W (see FIG. 14 ) with respect to the frame member 180 . As a result, a force to separate the frame member 180 from the inner member 185 acts. When the frame member 180 inclines, the height of the frame member 180 at the rear end becomes lower, and the height of the vegetable compartment door 6 on the front side becomes lower, and the vegetable compartment door 6 becomes drooping. Therefore, in the present embodiment, when the storage container 101 is fully opened (after it is fully opened), the fixed position by the rivet 187 is set to the area where the inner member 185 and the outer member 184 overlap, thereby preventing it from being a fulcrum. The inclination of the frame member 180 at the rear portion of the portion P further suppresses the vegetable compartment door 6 from drooping.

In addition, in the present embodiment, since the fixing portion by the rivets 187A ( 187 ) is located on the vertical projection of the box bearing 182 , in other words, the box bearing 182 and the rivets 187A ( 187 ) overlap each other in the vertical direction (vertical direction). Therefore, the inclination of the frame member 180 at the fulcrum portion P can be suppressed. Since the inclination at the fulcrum portion P can be more reliably suppressed, the drooping posture at the position of the vegetable compartment door 6 can be reliably suppressed.

And, as mentioned above, if the whole storage container 101 is pulled out from the vegetable compartment 100 to fully open, then when the weight of the storage items stored in the storage container 101 is large, due to the force received from the storage container 101 The load F causes distortion (a force to deform the frame member 180 so as to fall inward) with respect to the frame member 180 . This twisting of the frame member 180 means that the lower surface portion 180c of the frame member 180 which is in contact with the box bearing 182 is deformed as shown by the dashed-dotted line S1 (see FIG. 14 ). As a result, the height of the frame member 180 at the end on the back side becomes lower, and the height of the vegetable compartment door 6 on the front side becomes lower, and the vegetable compartment door 6 becomes drooping.

Therefore, in this embodiment, when the storage container 101 is fully opened, since the rib 180f is located on the vertical projection of the box bearing 182 , in other words, it is arranged on the box bearing 182 and the rib 180f is on the side of the box bearing 182 . Since the positions overlap in the vertical direction, the distortion of the frame member 180 at the fulcrum portion P can be suppressed. Thus, since the distortion of the frame member 180 can be suppressed, the inclination of the frame member 180 can be suppressed, and the drooping of the vegetable compartment door 6 when the storage container 101 is fully opened can be suppressed.

Moreover, in this embodiment, since the hollow rivet is used as the rivet 187 fixing the frame member 180 and the inner member 185, the protrusion from the inner member 185 can be reduced, thereby preventing the tip of the rivet 187 from coming into contact with the retainer 191 of the slide rail 179. contact, and the joint strength between the frame member 180 and the inner member 185 can be improved compared to blind rivets.

Fig. 18 is a side view showing a second embodiment of the fixing method of the frame member and the inner member.

As shown in FIG. 18 , in the refrigerator of the second embodiment, rivets 187B and 187C for fixing frame member 180 and internal member 185 are provided. In the second embodiment, when the height of the rivet 187A in the first embodiment is H, the rivet 187B is positioned below the height H, and the rivet 187C is positioned above the height H (refer to the dotted line). The first embodiment is different. In addition, the positions of the rivets 187B, 187C in the front-rear direction (front-back) are the same as those of the first embodiment. In this way, by arranging the rivets 187B and 187C so as to be vertically shifted, the fulcrum can be separated from the twist of the frame member 180 and the twist can be reduced. As a result, since inclination of frame member 180 can be suppressed, drooping of vegetable compartment door 6 can be suppressed.

In addition, the vertical shift direction of the rivets 187B and 187C may be reversed. In addition, a structure may be adopted in which one rivet is at the center H and the other rivet is shifted in any direction up and down.

In addition, the rivets fixing the rear ends of the frame member 180 and the internal member 185 may be positioned behind the vertical projection of the box bearing 182 after the storage container 101 is pulled out to the maximum. Even with such a structure, the inclination by the twist of the frame member 180 can be suppressed, and the sagging of the vegetable compartment door 6 can be suppressed.

In addition, in the above-mentioned embodiment, the case where the straddling frame 167 and the frame bearing 181 are attached to the slide guide rail 179 through the connecting member 192 has been described as an example, but the connecting member 192 may not be provided but the straddling The frame 167 and the frame bearing 181 are directly attached to the structure of the slide rail 179 .

In addition, in the above-mentioned embodiment, the case where the storage container 101 is stored in the vegetable compartment 100 has been described as an example, but any storage container may be stored in the refrigerator 10 . In addition, in this embodiment, an example in which the internal member 185 with a small cross-sectional area is attached to the frame member 180 has been described, but conversely, the outer member 184 with a large cross-sectional area may be attached to the frame member 180.
