[0006]

As described above, in the conventional mounting structure of the interior component 1, the mounting on the clip mounting seat 2 is performed by sliding the clip on the clip mounting seat 2 in the direction of the arrow in FIG. It is pointed out that there is no restriction on the direction in which the clip 3 comes off, and that the clip 3 falls off before the interior component 1 is attached to the vehicle body panel 4, and that the smooth attachment of the interior component 1 cannot be guaranteed. .

Further, the clip 3 is positioned at an appropriate position on the clip mounting seat 2 by sliding the clip 3 onto the clip mounting seat 2 until the clip 3 comes into contact with a stopper piece 2c of the clip mounting seat 2. Panel 4
After mounting, the contraction force acts on the interior part 1 due to the difference in thermal shrinkage between the vehicle body panel 4 and the interior part 1 due to the fluctuation of the environmental temperature in the car, etc., but the clip 3 moves slightly in the removal direction. Although it is possible, the mounting hole 4a of the vehicle body panel 4 is set to have a long hole shape with respect to the contraction force of the interior component 1, and the clip 3 moves the mounting hole 4a of the vehicle body panel 4 in the arrow Y direction. By sliding, the contraction force of the interior component 1 is absorbed and the interior component 1 is not deformed.

However, since the mounting hole 4a of the vehicle body panel 4 is set to have a long hole shape, the rigidity of the vehicle body panel 4 is reduced, and external noise and the like easily enter the vehicle interior through the mounting hole 4a. The disadvantage of poor performance has been pointed out.

The present invention has been made in view of such circumstances, and in a mounting structure of an interior component to be mounted on a vehicle body panel by a clip method, a clip is surely prevented from falling off before the interior component is mounted. In addition to assuring the smooth mounting of the interior parts, the clip is slid along the direction of expansion and contraction of the interior parts with respect to the clip mounting seat, so that the mounting hole of the body panel can be downsized, and the rigidity of the body panel can be enhanced and It is an object of the present invention to provide a mounting structure of interior parts for improving sound insulation in a vehicle cabin.

[0010]

In order to achieve the above object, according to the present invention, a clip is mounted on a clip mounting seat formed on the back surface of an interior part, and an elastic piece of the clip is inserted into a mounting hole of a vehicle body panel. In the mounting structure of the interior component, in which the interior component is mounted on the vehicle body panel by press-fitting, the clip is outwardly bent at both ends of a pair of leg pieces bent in an inverted U-shape. A locking flange is formed, and an elastic piece formed by cutting and raising substantially the center of the leg is provided with a locking portion bent outward, while a clip mounting seat for mounting the clip is provided with a support rib. Side wall ribs are set on both sides, and a locking groove for slidingly mounting a clip locking flange is formed on the lower inner wall surface of the side wall rib. Engage A notch is formed, and before the interior component is mounted on the vehicle body panel, the locking portion of the clip is locked in the notch of the side wall rib in the clip mounting seat, thereby restricting movement of the clip in the insertion direction. At the same time, after the interior component is mounted on the vehicle body panel, the elastic piece is bent inward, the locking portion is disengaged from the notch of the clip mounting seat, and movement in the clip insertion direction is allowed.

[0011]

As is apparent from the above configuration, in order to mount the clip on the clip mounting seat, the locking flange of the clip is slid and mounted in the locking groove provided on the inner surface of the side wall rib of the clip mounting seat. If the engaging portion provided at the tip of the elastic piece is engaged with the notch provided on the inner surface of the side wall rib of the clip mounting seat, the clip is housed in the engaging groove, and the elastic piece is further provided in the notch. Because the locking part of
The clip can be securely mounted on the clip mounting seat.

Furthermore, after the clip is mounted on the clip mounting seat, the elastic piece of the clip is forcibly pressed into the mounting hole of the vehicle body panel, so that the fitting portion of the elastic piece is pressed inward and the tip of the elastic piece is locked. The part comes off from the notch on the inner surface of the side wall rib of the clip mounting seat, and the clip only has the locking flange fitted into the locking groove on the inner surface of the side wall rib of the clip mounting seat,
The clip is slidable with respect to the clip mounting seat along the expansion and contraction direction of the interior component.
