Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an accessory mounting structure for an automobile.

(Prior art) Conventionally, the methods for attaching automobile accessories such as ornaments and marks to the base plate include attaching them with double-sided adhesive tape, fixing them with screws, or inserting protrusions made on the accessories into holes made in the base plate. Measures such as press-fitting and attaching are adopted. These accessories are installed using double-sided adhesive tape or screws, so they cannot be installed with one touch and are less workable; Although it is possible to do this, it is not a preferable method because it tends to loosen, that is, play, due to changes in temperature over time after installation. In addition, the Utility Model No. 49, which is considered as prior art.
As disclosed in Publication No. 136109, as a chassis fixing device for attaching a chassis to a synthetic resin mounting plate, a synthetic resin mounting plate is provided with a protrusion and an elastic claw, and the elastic claw of the chassis is provided with a protrusion and an elastic claw. There is one in which a window is provided at the corresponding position, and the claws of the synthetic resin mounting plate are inserted and locked into the windows, and the chassis is held between the protrusion and the claws to secure the chassis. .

(Problems that the invention aims to solve) The methods of attaching accessories to the base plate using double-sided adhesive tape or screws are inferior in workability as the accessories cannot be attached with one touch, and the method of fixing protrusions by press-fitting them into holes Although it can be installed with one touch, there are problems such as loosening and rattling due to changes in temperature and over time after installation. Furthermore, even in the structure disclosed in Japanese Utility Model Application Publication No. 49-136109, the claw portion of the synthetic resin mounting plate is inserted and locked into the window portion of the chassis, and the chassis is held between the protruding portion and the claw portion. Although this allows for one-touch installation, due to aging, temperature changes after installation, and errors or variations in the dimensional accuracy of the product, it may be necessary to keep the clamping between the protrusion and the claw in a stable state for a long period of time. It was difficult to maintain the grip for a long period of time, and it was not sufficient to completely prevent the occurrence of rattling.

Therefore, the purpose of the present invention is to provide an automobile that can be installed with one touch, and that can maintain the installed state reliably without causing looseness even when there are changes over time and temperature after installation, or when there are variations in the dimensional accuracy of the product. The aim is to provide a mounting structure for accessories.
