Disclosure of Invention

Problems to be solved by the invention

The auxiliary handle is mounted on the top surface of the car body, rotates from the storage state when in use, and is used as a handle for supporting the body of a passenger when getting on or off the car, and a considerable load acts on the auxiliary handle according to different conditions. Since the rotation is attempted in addition to the large load, the hinge portion of the assist grip is highly accurate in mounting. However, there is a dimensional tolerance in the size and shape of two rectangular holes provided in a body panel of a vehicle body to which a hinge portion of an auxiliary handle is attached. For example, as shown in a of fig. 17, when an error of an angle α occurs in the hole of the other rectangular hole BH2 with respect to the hole of the one rectangular hole BH1, or as shown in B of fig. 17, when an error of an angle β occurs in the surface of the other rectangular hole BH2 with respect to the surface of the one rectangular hole BH1, there may be an error within a dimensional tolerance between the two rectangular holes BH1 and BH 2.

However, since the conventional assist grip has a high mounting accuracy with respect to the mounting portion, when there is an angular error of the hole or an angular error of the surface of the two rectangular holes, the mounting position and the mounting angle of the hinge portion on the other side with respect to the hinge portion on the one side of the assist grip are different, and therefore a strong stress is generated on the rotation axis of the hinge portion. Therefore, the conventional assist grip has the following problems: the angle error of the holes and the angle error of the surfaces of the two rectangular holes cannot be absorbed, and a strong stress is generated in the bending direction of the rotation shaft of the hinge part, and thus, an operation failure such as poor storage of the auxiliary handle may be generated.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an auxiliary handle that can absorb errors in two rectangular holes for mounting provided in a vehicle body mounting portion, and that can be mounted at a fixed position of the vehicle body mounting portion with good workability and in a proper manner.

Solution for solving the problem

The auxiliary handle of the present invention comprises:

a handle body integrally formed with hinge recesses formed in the base portions of the left and right ends thereof;

a hinge section having a hinge body provided with a rectangular opening in the front-rear direction, a flat-plate-shaped center support plate protruding rearward in the rectangular opening, and hinge recesses rotatably attached to both ends of the hinge section via a pivot shaft;

a mounting jig formed by bending a metal plate having spring elasticity into a substantially U-shape and providing elastic leg portions on both sides of a free end portion side, the mounting jig having elastic bulging portions bulging outward of the elastic leg portions, the mounting jig being mounted in the rectangular opening portion; and

a cover part having a cover main body provided with a pair of jig supporting parts inserted from the front of the rectangular opening part to the inner sides of the elastic leg parts of the mounting jigs, the cover main body covering the front surface of the hinge part and being fitted to the hinge main body,

The hinge portion is fixed to the vehicle body mounting portion by inserting the mounting jig and the jig supporting portion of the cover portion into a rectangular hole provided in the vehicle body mounting portion, characterized in that,

a cylindrical projection is provided on a center line of the center support plate parallel to the front-rear direction, and a holding groove is provided on the inner side of the jig support part in the front-rear direction, and the cylindrical projection is fitted into the holding groove.

According to the auxiliary handle of the present invention, the mounting jig and the jig supporting portion are inserted into and fixed to the rectangular hole provided in the vehicle body. The central support plate of the hinge body is gripped inside the clamp support portion, and the grip groove of the clamp support portion and the mounting clamp are supported so as to be tiltable around the cylindrical projection with respect to the cylindrical projection of the central support plate. That is, the mounting jig and the jig support portion are supported with respect to the hinge body so as to be tiltable to the left and right about the cylindrical convex portion in the front-rear direction with respect to the rectangular hole. Therefore, in the auxiliary handle according to the present invention, even if an angular error occurs in two rectangular holes provided in the vehicle body, the attachment jig and the jig support portion of the cover portion can tilt in accordance with the angular error of the rectangular holes, and therefore, the hinge main body can be held in place, and the attachment jig and the cover portion can be tilted to absorb the angular error of the rectangular holes. This can prevent the occurrence of bending stress on the rotation shaft (pivot) of the hinge portion due to an angular error of the rectangular hole, and can properly attach the assist grip to the fixed position of the vehicle body with good workability.

Here, in the above-described assist grip, a seat portion that is in contact with a surface outside the rectangular hole of the vehicle body attachment portion may be provided on a rear end outer peripheral portion of the rectangular opening portion of the hinge main body, and an inclined surface that is inclined from a center position to both sides may be provided on the seat portion.

Thus, the hinge portion is allowed to tilt with respect to the outer side surface of the rectangular hole of the vehicle body mounting portion by the inclined surface provided in the seat portion. Therefore, even if an angle error occurs on the surfaces of the two rectangular holes provided in the vehicle body mounting portion, the angle error of the hinge main body with respect to the surface of the rectangular hole can be properly inclined, and the angle error of the surface can be absorbed, thereby preventing bending stress occurring on the rotation axis of the hinge portion.

In the auxiliary handle, inclined surfaces inclined toward both sides may be provided on both sides of the cylindrical protruding portion on the center support plate.

Thus, since the inclined surfaces are provided on both sides of the cylindrical protruding portion on the center support plate fitted to the jig support portion, the range of allowable rotation angles of the mounting jig and the jig support portion that can tilt with respect to the center support plate can be appropriately set. Therefore, the auxiliary handle can be attached to the rectangular hole of the vehicle body without rattling the hinge portion.

In the auxiliary handle, a cutout may be provided at both ends in the width direction of the rear side of the center support plate.

Thus, the rear end portion of the center support plate, which becomes the insertion side when the auxiliary handle is attached to the rectangular hole, becomes thin in the width direction due to the cutout portion. Therefore, the mountability to the rectangular hole of the vehicle body panel can be improved.

In the auxiliary handle, the width of the elastic leg portion of the attachment clip on the distal end side may be smaller than the width of the elastic leg portion on the proximal end side.

This can improve the mountability of the mounting jig when inserted into the rectangular opening of the hinge body.

The auxiliary handle of the present invention comprises:

a seat portion that abuts against a surface of the vehicle body mounting portion outside the rectangular hole is provided on a rear end outer peripheral portion of the rectangular opening portion of the hinge main body, and an inclined surface that is inclined from a center position to both sides is provided on the seat portion.

According to the present invention, the hinge portion is allowed to tilt with respect to the outer side surface of the rectangular hole of the vehicle body mounting portion by the inclined surface provided to the seat portion. Therefore, even if an angle error occurs on the surfaces of the two rectangular holes provided in the vehicle body mounting portion, the angle error of the hinge main body with respect to the surface of the rectangular hole can be properly inclined, and the angle error of the surface can be absorbed, thereby preventing bending stress occurring on the rotation axis of the hinge portion.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the auxiliary handle of the present invention, it is possible to prevent the occurrence of bending stress on the rotation shaft of the hinge portion due to an angular error of the rectangular hole for attachment, and to attach the auxiliary handle to the fixed position of the vehicle body with good workability and with good accuracy.

An outer shaft hole 14 into which a projection 23a of a hinge body 21 described later is fitted is formed on the right side (outer side) of opposite side walls (left and right walls) of the inner peripheral wall in the hinge recess 11, and an inner shaft hole 13 into which the pivot shaft 8 is fitted through a shaft hole 22a of the hinge body 21 is formed on the left side (inner side). The outer shaft hole 14 and the inner shaft hole 13 are formed on the same axis. An outer shaft hole 14 into which the boss 33a of the hinge body 31 fits is formed on the left side (outer side) of the opposite side walls of the inner peripheral wall in the hinge recess 12 of the hinge body 31 accommodating the hinge portion 3, an inner shaft hole 13 into which the pivot shaft 8 fits through the shaft hole 32a of the hinge body 31 is formed on the right side (inner side), and the outer shaft hole 14 and the inner shaft hole 13 are formed on the same axis.

As shown in fig. 2 and 7, the right hinge portion 2 includes: a hinge body 21; a mounting jig 5 made of a metal plate, the mounting jig 5 being fitted into the hinge body 21 and fitted into and locked to the vehicle body mounting portion (rectangular hole BH (a of fig. 16) of the vehicle body panel BP); a cover 4 provided with a jig support 42 supported from the front on the inner side of the mounting jig 5, the cover 4 covering and fitting the hinge body 21; and a return spring device 6 for biasing the handle body 1 to a housed state in which the hinge portion 2 is housed.

As shown in fig. 3 and 4, the hinge body 21 of the right hinge part 2 is formed in a substantially cubic shape having a substantially square front surface. As shown in fig. 4B, the hinge main body 21 has a rectangular opening 27 in the front-rear direction above the hinge main body, a flat-plate-shaped center support plate 28 is provided in the rectangular opening 27 so as to protrude rearward, and a cylindrical projection 29 is provided on a center line CS of the center support plate 28 parallel to the front-rear direction as shown in fig. 4 a.

The rear side of the center support plate 28 is provided with cutout portions 28b at both ends in the width direction to improve the mountability to the rectangular hole. As shown in fig. 9B, inclined surfaces 28a inclined so as to be thinned toward the left and right end sides of the center support plate 28 are provided at four positions on the left and right sides of the cylindrical projection 29 on the center support plate 28. The angle a ° of the inclined surface 28a with respect to the horizontal line is set in accordance with an angle setting within a dimensional tolerance generated in the rectangular hole BH of the vehicle body mounting portion. As shown in D of fig. 4, side plates 28c that restrict deformation of the center support plate 28 in the up-down direction are provided at both left and right end portions of the center support plate 28. As shown in fig. 4B, a seat portion 24 that contacts a vehicle body panel BP that is an outer surface of a rectangular hole BH is provided on a rear end outer peripheral portion of a rectangular opening 27 of the hinge main body 21, and as shown in fig. 10, an inclined surface 24a that is inclined from a center position to both sides is inclined to both sides at an angle B ° with respect to the contact surface.

As shown in fig. 5, the mounting jig 5 is formed by bending a metal plate having spring elasticity into a substantially U-shape, and the elastic leg portions 51 are formed to have spring elasticity on both sides of the free end side. The left and right elastic leg portions 51 of the attachment jig 5 are formed so that the elastic bulge portion 52 is elastically deformable so as to be opened outward from the elastic leg portions 51, and a 1 st locking portion 53 and a flat plate-like 2 nd locking portion 54 which are bent in a substantially L-shape are formed at the tip end of the elastic bulge portion 52. Thus, as shown in fig. 15B, when the mounting jig 5 is inserted into the rectangular hole BH of the vehicle body panel BP serving as the fixed portion, the 1 st locking portion 53 is locked to the edge portion of the rectangular hole BH, and the tip end of the 2 nd locking portion 54 is locked to the rear surface of the vehicle body panel BP. A step 55 is formed near the distal ends of the elastic leg portions 51 on both sides so as to be bent at a substantially right angle to the elastic leg portions 51, and a protruding portion 56 is formed so as to extend substantially parallel to the insertion direction of the attachment jig 5, that is, substantially parallel to the elastic leg portions 51, on the distal end side of the step 55. As shown in fig. 5 a, the width W2 of the distal end portion of the elastic leg portion 51 is smaller than the width W1 of the root portion of the elastic leg portion 51. Thus, when the attachment jig 5 is inserted into the rectangular opening 27 of the hinge main body 21, the work is easy.

As shown in D of fig. 6, the cover 4 includes a cover body 41 that covers the front surface of the hinge 2 and is fitted to the hinge body 21, and a pair of upper and lower clip support portions 42 that are inserted into the inner sides of the elastic leg portions 51 of the mounting clip 5 are provided to protrude rearward on the back surface side of the cover body 41. The left and right end portions of the jig support portion 42 support the mounting jig 5 by abutting the elastic leg portions 51 of the mounting jig 5, and the intermediate portion other than the left and right end portions is opened in the up-down direction. A gap 42a through which the central support plate 28 of the hinge body 21 penetrates is provided between the upper and lower sides of the clamp support portion 42, and grip grooves 43 that fit into the cylindrical projections 29 of the central support plate 28 are provided on the upper and lower surfaces in the front-rear direction of the inner side of the clamp support portion 42. Since the cylindrical protruding portion 29 shown in fig. 9 is inserted into the upper and lower holding grooves 43 and the inclined surfaces 28a are provided on the upper and lower left and right sides of the cylindrical protruding portion 29, if an angle error such as a in fig. 17 exists in the rectangular hole BH, the mounting jig 5 and the lid 4 are inclined with respect to the hinge main body 21 in accordance with the angle error, and stress applied to the hinge portion 2 is prevented. An abutment portion 44 that abuts against the inside of the 1 st locking portion 53 of the mounting jig 5 is provided on the outside of the jig supporting portion 42. The lid body 41 on the front side of the clip support portion 42 is provided with a pressing portion 45 for pressing the front side of the stepped portion 55 of the attachment clip 5 rearward, and three portions on the inner side of the outer periphery of the lid body 41 are provided with locking claws 46 that are locked with the lid locking portions 26 of the hinge body 21.

Since the jig support portion 42 is supported so as to be tiltable around the cylindrical convex portion 39 of the central support plate 38 of the hinge main body 31, as shown in fig. 13B, the mounting jig 5 and the jig support portion 42 are supported so as to be tiltable to the left and right sides within the range of the angle a ° around the center line CS of the cylindrical convex portion 39 in the front-rear direction with respect to the rectangular hole.

The boss 33a is provided on the outer side of the outer support piece 33 on the lower side of the left outer wall portion of the hinge main body 31, the boss 33a is rotatably fitted into the outer shaft hole 14 of the hinge recess 12 of the handle main body 1, and the inner support piece 32 on the lower side of the right outer wall portion is provided with a shaft hole 32a, and the shaft hole 32a is penetrated by the pivot shaft 8 and rotatably supported by the inner shaft hole 13 of the hinge recess 12 via the pivot shaft 8. The boss 33a is rotatably pivotally supported by an outer shaft hole 14 formed in an inner peripheral wall of the hinge recess 12, and the shaft hole 32a is rotatably pivotally supported by the pivot shaft 8 fitted into the inner shaft hole 13 of the hinge recess 12, so that the hinge body 31 is configured to rotatably support the handle body 1 in the hinge recess 12 of the handle body 1. A hydraulic damper accommodating portion 35 that accommodates the hydraulic damper 7 is provided on an axis between the boss 33a and the shaft hole 32 a. The fitting portion 8a of the pivot shaft 8 inserted into the inner shaft hole 13 through the shaft hole 32a is disposed inside the inner support piece 32 that is the right wall portion of the hydraulic shock absorber housing portion 35, and the positioning recess 33b into which the fitting protrusion 75 of the hydraulic shock absorber 7 is fitted is formed inside the outer support piece 33 that is the left wall portion of the hydraulic shock absorber housing portion 35.

The hydraulic damper 7 that generates braking force when the handle body 1 rotates is accommodated and mounted in the hydraulic damper accommodating portion 35. The hydraulic damper 7 is constituted by an inner tube 72 of a cylindrical body and an outer tube 71 rotatably attached so as to enclose the inner tube 72, and a gap formed between the inner tube 72 and the outer tube 71 is filled with oil, and when the inner tube 72 and the outer tube 71 are relatively rotated, a braking force is generated by viscous resistance of the oil.

As shown in fig. 8, the hydraulic damper 7 has a convex fitting protrusion 75 on the left side wall surface of the inner tube 72, and a bearing portion, not shown, formed on the right side wall surface. For insertion of the hydraulic damper 7, first, the hinge body 31 is fitted into the hinge recess 12, and the pivot shaft 8 is inserted into the inner shaft hole 13 from the shaft hole 32 a. Thus, the fitting portion 8a to be fitted to the bearing portion of the hydraulic damper 7 is disposed inside the inner support piece 32 that is the right wall portion of the hydraulic damper accommodating portion 35. The bearing portion of the hydraulic damper 7 is fitted to the fitting portion 8a of the pivot shaft 8, and the fitting protrusion 75 of the hydraulic damper 7 is fitted to the positioning recess 33b on the inner side of the outer support piece 33. A guide groove, not shown, is formed behind the positioning recess 33b so that the fitting protrusion 75 easily enters the positioning recess 33b.

As shown in fig. 8, a protruding portion 73 is provided on the outer peripheral portion of the outer tube 71 so as to protrude, and when the handle body 1 is attached to the hinge body 31 and the hydraulic damper 7 is inserted into the hydraulic damper accommodating portion 35 of the hinge body 31, the protruding portion 73 is engaged with a protruding engagement portion 12a provided in the hinge recess 12, and when the handle body 1 is rotated, the outer tube 71 of the hydraulic damper 7 rotates together with the handle body 1. Since the hinge portion 3 is fixed to the body panel BP of the vehicle body and the fitting protrusion 75 at the end portion of the inner tube 72 of the hydraulic damper 7 is engaged with the positioning recess 33b of the hinge portion 3, when the handle body 1 is rotated relative to the hinge portion 3, the outer tube 71 of the hydraulic damper 7 is operated to rotate relative to the inner tube 72 and impart an appropriate rotational resistance.

The auxiliary handle having the above-described structure is assembled as follows. First, the clip support portion 42 is inserted into the rectangular opening portions 27, 37 of the hinge

main bodies

21, 31, respectively, with respect to the lid portion 4, and is brought into a temporarily fixed state. Next, the mounting jigs 5 are assembled to the hinge body 21 and the hinge body 31, respectively, to which both sides of the cover 4 are temporarily fixed. The attachment jig 5 is inserted into the rectangular opening 27 of the hinge main body 21 from the back surface side (rear surface side) so that the end portion of the front surface side of the attachment jig 5 on the side of the protruding portion 56 is elastically deformed outward. The upper and lower elastic leg portions 51 of the mounting jig 5 sandwich the jig support portion 42, whereby the mounting jig 5 is assembled to the hinge

main bodies

Next, as shown in fig. 2, 7, and 8, the hinge portion 2 is mounted in the hinge recess 11 of the handle body 1, and the hinge portion 3 is mounted in the hinge recess 12.

The boss 23a of the hinge body 21 is fitted into the outer shaft hole 14 on the right side (outer side) of the inner peripheral wall of the hinge recess 11 of the handle body 1, and the shaft hole 22a of the inner support piece 22 of the hinge body 21 is disposed on the axis of the inner shaft hole 13 on the left side (inner side) of the inner peripheral wall of the hinge recess 11. Next, the pivot shaft 8 is inserted into the shaft hole 22a of the inner support piece 22 from the side of the spring housing accommodating portion 25 corresponding to the inner side of the hinge body 21, and fitted into the inner shaft hole 13 of the hinge recess 11. Thus, the handle body 1 is pivotally supported by the hinge 2 so as to be rotatable.

In the hinge portion 3, similarly, the boss 33a of the hinge body 31 is fitted into the left (outer) outer shaft hole 14 of the inner peripheral wall of the hinge recess 12 of the handle body 1, and the shaft hole 32a of the inner support piece 32 of the hinge body 31 is disposed on the axis of the right (inner) inner shaft hole 13 of the inner peripheral wall of the hinge recess 12. Next, the pivot shaft 8 is inserted into the shaft hole 32a of the inner support piece 32 from the side of the hydraulic damper accommodating portion 35 corresponding to the inside of the hinge body 31, and fitted into the inner shaft hole 13 of the hinge recess 12. Thus, the handle body 1 is pivotally supported by the hinge portion 3 so as to be rotatable.

The return spring device 6 is accommodated in the spring housing accommodating portion 25 of the hinge main body 21. The bearing portion 65 of the left wall portion of the return spring device 6 is fitted into the fitting portion 8a of the outer side of the pivot shaft 8 fitted from the side of the spring housing accommodating portion 25, and the fitting convex portion of the right wall portion of the return spring device 6 is fitted into the positioning concave portion 23b formed on the right inner side of the spring housing accommodating portion 25, so that the return spring device 6 is accommodated in the spring housing accommodating portion 25 of the hinge main body 21. At this time, the intermediate leg portion 61b of the double torsion spring 61 protruding from the opening 64 of the spring housing 62 is engaged with the spring engagement portion 11a of the hinge recess 11, and the handle body 1 is biased to a housed state in which the hinge portion 2 is housed.

Similarly, the hydraulic damper 7 is accommodated in the hydraulic damper accommodating portion 35 of the hinge body 31. The bearing portion of the right wall portion of the hydraulic damper 7 is fitted into the fitting portion 8a of the outer side of the pivot shaft 8 fitted from the hydraulic damper accommodating portion 35 side, and the fitting protrusion 75 of the left wall portion of the hydraulic damper 7 is fitted into the positioning recess 33b formed on the left inner side of the hydraulic damper accommodating portion 35, so that the hydraulic damper 7 is accommodated in the hydraulic damper accommodating portion 35 of the hinge main body 31. At this time, the protruding portion 73 protruding from the outer tube 71 of the hydraulic damper 7 is engaged with the protruding engagement portion 12a of the hinge recess 12, whereby a braking force is applied to the handle body 1 at the time of rotation.

As described above, as for the assist grip, as shown in fig. 1, the assist grip in a delivery state to an automobile manufacturer or the like is completed. The assist grip is mounted in a rectangular hole BH of a body mounting portion (body panel BP) of a ceiling surface or a wall surface in a vehicle cabin by an automobile manufacturer or the like.

When the auxiliary handle is fixed to the rectangular hole BH of the body panel BP inside the interior material IP provided on the top or side wall surface in the cabin of the automobile, the handle body 1 of the auxiliary handle is gripped, and the distal ends of the clip support portion 42 and the attachment clip 5 of the hinge portion 2 and the distal ends of the clip support portion 42 and the attachment clip 5 of the hinge portion 3 are respectively press-fitted into the rectangular hole BH provided in the body panel BP of the body attachment portion.

At this time, as shown in a of fig. 15, the mounting jig 5 is fitted into the rectangular hole BH while the elastic bulge 52 is elastically deformed inward. When the elastic bulge 52 of the attachment jig 5 is completely fitted into the rectangular hole BH, the 1 st locking portion 53 and the 2 nd locking portion 54 of the elastic bulge 52 are elastically restored so as to be opened outward, and the 1 st locking portion 53 is locked to the edge of the rectangular hole BH of the vehicle body panel BP and the tip end of the 2 nd locking portion 54 is locked to the back surface (inner surface) of the vehicle body panel BP. Thus, the hinge body 21 is held between the seat 24 and the 2 nd locking portion 54 of the hinge body 21 by the edge portion of the rectangular hole BH of the body panel BP, and the 2 nd locking portion 54 of the elastic bulge portion 52 is locked to the back surface of the body panel BP by the tip end thereof, so that the hinge body 21 is fixed to the body panel BP with high release resistance and assembled. Similarly, with respect to the hinge body 31, the edge portion of the rectangular hole BH of the body panel BP is sandwiched between the seat portion 34 and the 2 nd locking portion 54 of the hinge body 31, and the 2 nd locking portion 54 of the elastic bulge portion 52 is locked to the rear surface of the body panel BP by the tip end thereof, so that the hinge body 31 is fixed to and assembled with the body panel BP with a high release resistance.

When there is an angular error in the rectangular hole BH of the vehicle body panel BP, the

clip support portions

42, 42 are supported so as to be tiltable about the

cylindrical projections

29, 39 of the

central support plates

28, 38 of the

respective hinge bodies

21, 31, and therefore, as shown in B of fig. 13, the attachment clips 5, 5 and the

clip support portions

42, 42 are allowed to tilt about the center line CS of the

cylindrical projections

29, 39 in the front-rear direction of the rectangular hole to the left and right sides within the range of the angle a ° with respect to the

hinge bodies

21, 31, respectively. When the mounting jig 5 and the jig support portion 42 tilt in one direction with respect to the hinge body 21, the mounting jig 5 and the jig support portion 42 can tilt in the other direction with respect to the hinge body 31, and therefore, by this tilting, an angular error of the rectangular hole BH of the vehicle body panel BP is absorbed. This prevents bending stress that is easily applied to the pivot shaft 8 (pivot shaft 8 of the pivot handle body 1) that pivotally supports the left and

right hinge portions

2, 3, and enables the assist handle to be mounted at a fixed position of the vehicle body with good workability and in an appropriate manner.

Further, as shown in fig. 10, the inclined surfaces 24a inclined to the left and right sides from the center position are provided so as to be able to tilt the hinge body 21 to the left and right sides in the seat portion 24 of the hinge body 21, and as shown in fig. 12, the inclined surfaces 34a inclined to the left and right sides from the center position are provided so as to be able to tilt the hinge body 31 to the left and right sides in the seat portion 34 of the hinge body 31. Therefore, when there is an angular error in the surface of the rectangular hole BH of the vehicle body panel BP, the

hinge bodies

21, 31 are properly inclined with respect to the angular error in the surface of the rectangular hole BH, and the angular error in the surface is absorbed. This prevents bending stress that is easily applied to the pivot shaft 8 (pivot shaft 8 of the pivot handle body 1) that pivotally supports the left and

right hinge portions

Thereafter, as shown in fig. 15, the lid 4 temporarily fixed to the hinge body 21 is pushed in, and the clip support portion 42 is pushed in the rectangular opening 27. At this time, the inner locking claw 46 of the lid 4 is completely fitted into and locked to the lid locking portion 26 on the outer side of the hinge body 21. Similarly, the lid 4 temporarily fixed to the hinge body 31 is pushed in, and the clip support portion 42 is pushed in the rectangular opening 37. The locking claw 46 on the inner side of the lid 4 is completely fitted into and locked to the lid locking portion 36 on the outer side of the hinge body 31. At this time, as shown in fig. 15B, the clip support portion 42 of the cover portion 4 is completely fitted into the mounting clip 5, and the 1 st locking portion 53 and the 2 nd locking portion 54 of the elastic bulge portion 52 of the mounting clip 5 are firmly locked to the body panel BP as the fixed portion, thereby completing the mounting of the assist grip.

When using the auxiliary handle, the user rotates the handle body 1 downward (from the solid line position to the dot-dash line position in fig. 16) with respect to the hinge portion 2 and the hinge portion 3. At this time, the intermediate leg portion 61b of the coil spring 6 is twisted against the spring force of the coil spring 6 by the rotation of the spring engagement portion 11a of the handle body 1. Thereby, the handle body 1 is turned downward against the spring force, and the user holds the handle body 1 in the use state by holding the handle body 1. On the other hand, when the user's hand is separated from the handle body 1 in the use state of the assist handle, the handle body 1 is biased downward (clockwise in fig. 16 a) from the middle foot portion 61b of the coil spring 6, and is rotated in this direction, and returns to the non-use state (solid line position in fig. 16 a). At this time, the rotation of the handle body 1 is braked by the hydraulic damper 7, and the biasing force to the handle body 1 is weakened to return to the position in the non-use state.
