It is arranged like this. In addition, a portion of the main body portion 11 of the leg cover 10 that is formed wider than the convex portion 11 a is formed with a width that is substantially equal to the width of the leg bracket 20 so as not to protrude from the width in the left-right direction of the leg bracket 20. ing. Therefore, even when the leg cover 10 is attached to the leg bracket 20 disposed in the recess formed in the vehicle body floor F, the leg cover 10 can be easily attached. As described above, the leg cover 10 having the above configuration can be easily attached even when it is difficult to secure a sufficient space around the leg bracket 20.

As shown in FIG. 6, the hook-shaped first locking portion 12 that protrudes rearward from the main body portion 11 of the leg cover 10 is inserted and locked into a hole 22 provided in the leg bracket 20. The
Conventionally, the leg cover is formed to be wider (so as to cover a wider area) than the leg bracket, and the leg cover is often configured to sandwich the leg bracket from the side. On the other hand, like the present invention, by inserting the first locking portion 12 into the leg bracket 20, there is no need to increase the size of the leg cover 10 to the outside of the range where the leg bracket 20 is provided. Therefore, it is possible to suppress an increase in the size of the peripheral structure of the leg bracket 20 to which the leg cover 10 is attached.

On the other hand, on the back surface of the leg cover 10, the hook-shaped second locking portion 13 formed so as to protrude inward from the periphery is locked to the claw portion 23a. Thus, since the 2nd latching | locking part 13 is provided inside the periphery of the leg cover 10, it is not necessary to enlarge the leg cover 10 more than necessary, and the downward flat part 21c of the leg bracket 20 substantially. (And the flange part 23 provided at the periphery of the lower flat part 21c) is formed in substantially the same size.
In this way, by locking the first locking portion 12 and the second locking portion 13 provided at the end portions in the front-rear direction of the leg cover 10 with respect to the leg bracket 20, the leg cover 10 Therefore, it is not necessary to secure a large surrounding space. Therefore, the leg cover 10 can be easily attached to the leg bracket 20 even when a sufficiently wide space is not secured around the leg bracket 20.

  As shown in FIG. 7, the first locking portion 12 is inserted through the hole 22 formed in the leg bracket 20 to the back surface side of the leg bracket 20. The portion is locked in a state of contacting a part of the back surface of the leg bracket 20. Therefore, even when an external force that lifts the leg cover 10 upward is applied to the leg cover 10, the first locking portion 12 contacts the back surface of the leg bracket 20, so that the leg cover 10 moves upward. It can suppress that it remove | deviates toward.

  On the other hand, the 2nd latching | locking part 13 is latched so that it may contact | abut from the downward direction with respect to the nail | claw part 23a with which the leg bracket 20 was equipped. This 2nd latching | locking part 13 is extended inward rather than the outer peripheral edge part of the nail | claw part 23a, and is formed in the hook shape. And this hook-shaped 2nd latching | locking part 13 contact | abuts to the nail | claw part 23a, and is latched.

  As described above, the leg cover 10 is attached to the leg bracket 20 by locking the first locking portion 12 and the second locking portion 13 to the leg bracket 20.

  Further, as described above, a position restricting portion 14 including a pair of position restricting surfaces 14 a and 14 a provided at a position sandwiching the second locking portion 13 is provided on the back surface of the leg cover 10. The position restricting surface 14a is locked in a state where it abuts on a recess 23b formed by cutting out a part of the flange 23 of the leg bracket 20. That is, as shown in FIG. 8, the leg cover 10 is attached to the leg bracket 20 with the claw portion 23a of the flange portion 23 sandwiched between the position restricting surfaces 14a.

  Thus, since the claw part 23a can be pinched | interposed with the position control surfaces 14a and 14a, when attaching the leg cover 10 with respect to the leg bracket 20, the position of the left-right direction of the leg cover 10 can be determined easily. . Therefore, it is possible to easily perform the attaching operation of the leg cover 10.

<Leg cover installation process>
Next, a process of attaching the leg cover 10 to the leg bracket 20 will be described with reference to FIGS.
FIGS. 9A, 9B, and 9C are perspective views showing a process of attaching the leg cover 10 to the leg bracket 20, and FIG. 9A shows a state before the leg cover 10 is attached (rotation). FIG. 9 (b) shows a state during attachment (during rotation), and FIG. 9 (c) shows a state after attachment (after rotation). FIGS. 10A and 10B are sectional views showing a process of attaching the leg cover 10 to the leg bracket 20, and FIG. 10A is being attached (rotating). FIG. 10B shows a state after attachment (after rotation).

The leg cover 10 is attached to the leg bracket 20 by inserting the first locking portion 12 of the leg cover 10 into the hole 22 formed in the leg bracket 20 as shown in FIG. Be started. At this time, since the width of the hole portion 22 is slightly larger than the width and thickness of the first locking portion 12, the first locking portion 12 can be easily inserted into the hole portion 22. it can.
Furthermore, since the hole 22 is formed in the bulging part 21bx provided in the slope part 21b as described above, the first locking part 12 can be easily inserted.

  Next, the first locking portion 12 is inserted into the hole until the convex portion 11a constituting the main body portion 11 of the leg cover 10 abuts on the slope portion 21b (more specifically, the bulging portion 21bx) of the leg bracket 20. The leg cover 10 is rotated toward the leg bracket 20 side with the rear end of the leg cover 10 as the center of rotation. More specifically, the leg cover 10 is moved around the line segment (line X shown in FIG. 9B) passing through the portion where the rear end portion of the leg cover 10 and the inclined surface portion 21b come into contact with each other as shown in FIG. ) Push down in the direction of the arrow.

  At this time, as shown in FIG. 10 (a), the leg cover 10 rotates with the first locking portion 12 inserted into the hole 22, so that the leg cover 10 does not come off the leg bracket 20, Can be rotated easily.

  As shown in FIGS. 9C and 10B, the leg cover 10 is rotated to the mounting position of the leg bracket 20, and the upper side of the second locking portion 13 provided on the leg cover 10 is further lowered. The second locking portion 13 is elastically deformed by being pressed. When the second locking portion 13 is elastically deformed, the second locking portion 13 is slidably contacted with the end portion (front end) of the claw portion 23a and further pushed down, and the upper end of the second locking portion 13 and the leg cover The nail | claw part 23a is pinched | interposed between 10 main-body parts 11. That is, the second locking portion 13 is locked to the claw portion 23 a of the leg bracket 20. Thereby, the leg cover 10 is attached to the leg bracket 20.

  At this time, since the first locking portion 12 and the second locking portion 13 (leg cover 10) are formed of a flexible material, the first locking portion 12 and the second locking portion. A resilient force is applied to the portion 13, and as a result, the leg cover 10 can be firmly attached to the leg bracket 20. Hereinafter, the configuration and operation of the first locking member 12 and the second locking member 13 will be described in detail.

FIG. 10B is a longitudinal cross-sectional explanatory view of the center portion of the leg cover 10 and the leg bracket 20 in a state where the leg cover 10 is attached.
As described above, the leg cover 10 is attached to the leg bracket 20 by rotating the first locking portion 12 (more specifically, the line X shown in FIG. 9B) as the rotation center.

  Since the 2nd latching | locking part 13 is provided with flexibility at this time, due to the repulsive force at the time of elastic deformation, the force which pushes up the nail | claw part 23a upward from the downward direction is applied. As a result, the second locking portion 13 is firmly locked to the claw portion 23a. Further, since the second locking portion 13 is locked to the lower surface of the claw portion 23a, even if an external force that lifts the leg cover 10 upward is applied to the leg cover 10, the leg The cover 10 can be prevented from coming off upward.

  In addition, the first locking portion 12 provided to face the second locking portion 13 is formed of a flexible material like the second locking portion 13. And the force pushed up by the repulsive force at the time of the elastic deformation of the 2nd latching | locking part 13 is added to the 1st latching | locking part 12. FIG. That is, due to the repulsive force at the time of elastic deformation of the second locking portion 13, the leg cover 10 is in a state where a force in a direction of rotating upward around the first locking portion 12 is constantly applied. At this time, a force that further bends the first locking portion 12 is applied to the first locking portion 12 formed in a bowl shape. Therefore, the first locking portion 12 is pressed more strongly against the back surface of the leg bracket 20. As a result, the leg cover 10 is more firmly attached to the leg bracket 20, and the leg cover 10 can be made difficult to come off. Moreover, since the leg cover 10 is firmly attached, it is possible to suppress the position of the leg cover 10 from being displaced after the leg cover 10 is installed.

  Further, the slope 21b of the leg bracket 20 is formed to be inclined with respect to the extending direction (that is, the horizontal direction) of the surface (the lower surface of the claw 23a) that is locked with the second locking portion 13. Yes. Thus, in order to attach the leg cover 10 attached by rotating around one of the locking portions (the first locking portion 12), the hole 22 of the leg bracket 20 is provided in the slope portion 21b. The leg cover 10 can be easily rotated. As a result, the leg cover 10 can be easily attached to the leg bracket 20.

  In other words, the claw portion 23a for locking the second locking portion 13 is formed horizontally, while the hole portion 22 for locking the first locking portion 12 has a horizontal plane. Therefore, the leg cover 10 can be easily rotated, and the leg cover 10 can be easily attached.

  Moreover, the leg cover 10 can be made more difficult to come off by rotating and attaching the leg cover 10 as described above, rather than pressing the leg cover 10 straight from above with the leg bracket 20.
