[0006]

According to the present invention, there is provided a component (2) which is attached to the substrate (1) so that at least a part thereof is in contact with the substrate (1).
A surface part (3) attached so as to cover at least a part of the part (2), and the tip of the surface part (3) is the base material (1).
And a plastic clip (4) for attaching the exterior component (2) to the base material (1) by inserting it into a through hole provided in the component (2), and inside the surface component (3). A box boss (5) is formed integrally with the surface part (3), and a flange (4a) is formed on the head of the clip (3) and its tip is sharply formed with respect to the through hole. The brim (4a) is housed in the box boss (5), and the clip (4) is held so that the tip of the clip (4) protrudes from the end (5s) of the box boss (5).
Is formed with an opening (2p) having a shape through which the end of the box boss can pass at a position corresponding to the box boss.
A rib (6) is integrally formed with the surface part (3) on the side of the rib, and the rib (6) abuts the part (2) around the opening so that the clip (4) is attached to the base material. It is characterized in that the component (2) is pressed against the base material (1) while being inserted into the provided hole. The component (2) is a component called an exterior component or an interior component.

The numbers in the above parentheses are reference numbers in the embodiment drawings described later. This is given for easy understanding of the configuration of the invention, and is not for understanding the invention by limiting it to the embodiments (the same applies hereinafter).

The first feature of the present invention is to use a plastic clip (4) in place of the conventional screw. Then, a box boss (5) is formed inside the surface part (3, for example, a lens), and the head of the plastic clip (4) is held by the box boss (5). There are features. Furthermore, when the tip of the clip held by the box boss (5) is inserted into the through hole, the rib (6) formed on the side of the box boss (5) is not the tip of the box boss, but the rib (6) of the part (2). The third characteristic is the structure in which the surface is pressed against the base material (1, for example, body).

When the tip of the plastic clip passes through a hole provided in a base material (for example, a body), it is crushed and passes while contracting. It is a structure that cannot be easily pulled out after restoration. Therefore, it is not necessary to use a screw driver by using the plastic clip both in the manufacturing process and in the maintenance work for lamp replacement.

Since the plastic clip is held by the box boss and the tip of the clip is sharply formed with respect to the through hole, the surface component is applied to the approximate hole position in the assembling work, and the surface component is simply attached. By pressing the whole toward the base material (eg body), the hole positions of the surface parts and the parts are automatically aligned with the hole positions of the base material (eg body). Therefore, the work corresponding to the position alignment before the screw insertion is substantially unnecessary.

Furthermore, since the surface of the exterior component is not directly pressed by the tip of the box boss, but the surface of the component is pressed by the rib provided on the box boss, the optimum pressing force is set according to the thickness of the component. can do. As a result, parts can be attached with proper and uniform pressing force without using screws, and high reliability can be obtained.

Further, according to the present invention, the collar formed on the head of the clip (4) has a double structure (4a, 4b), and the first (4a) of the double structure is the box boss. It is housed in (5), and the second (4b) is outside the box boss (5), and the end (5b) of the box boss is clamped by the two flanges (4a, 4b). It is desirable to have a structure. With this structure, the clip does not drop out of the box boss during or before the attachment work, and an appropriate force can be applied to the clip when a pressing force is applied for attachment.

It is desirable that the rib (6) is formed so as to be parallel to the axis of the clip, that is, the direction of the through hole, and that a plurality of ribs are formed for one box boss. As a result, the rib structure becomes solid, and even if uneven pressing force is applied during installation work,
It is possible to avoid the inconvenience that the ribs and parts are damaged.

The flange of the head of the clip (4) is further formed in a triple structure, and the third flange (4c) has the opening (2) while the clip is inserted into the hole formed in the base material.
It is desirable to have a structure for pressing the surface of the base material that appears in p). Furthermore, an elastic washer is preferably inserted between the third flange (4c) and the surface of the base material (1). With this structure, an unnecessary space is not created between the brim of the clip and the surface of the base material.

With the above structure, one of the plurality of clips used for mounting the surface component can be replaced with a (conventional) screw which can be fastened from the surface by a driver. This is a consideration to maintain a high reliability track record by screw tightening. This is also to make it easier to understand how to remove the surface parts (lens) when performing lamp replacement maintenance.

After the position is adjusted using the above-mentioned clip for mounting one surface part, it is not necessary to perform the position adjustment for inserting the screw even if the remaining one is tightened with the screw. Even if only one screw is used, the manufacturing man-hour will not be so large.

During lamp replacement maintenance, when one screw is visible on the surface, the operator immediately thinks to loosen it with a screwdriver. Then, by loosening one screw, the whole becomes loose, and the work can be performed by pulling out the plurality of plastic clips with appropriate forces. If all the through holes are attached by plastic clips, the person replacing the lamp is not always familiar,
Improper operation such as prying open the surface parts with a driver may damage the surface parts,
This is because there is concern that this mounting structure will not be liked by users.
