Description

[Detailed description of the invention] This invention allows the back cover, on which pulp is pre-attached to the lamp body, on which a reflector, etc. is formed to reflect the light from the bulb, to be attached and detached without using any tools. The invention relates to vehicle lighting equipment.

In the conventional structure of attaching the back cover to the light body of a vehicle light, the back cover was set on a mounting boss that was erected integrally on the light body, and then it was attached from the rear using multiple screws. Therefore, if the valve went out, I used a tool such as a screwdriver to loosen the screw, then removed the back cover and replaced the pulp with a new one.

This has the disadvantage that replacing the valve is extremely troublesome, and if you don't have a tool such as a screwdriver, or if you lose a screw when removing the back cover, you may not be able to replace the pulp. , or it may not be possible to assemble the parts, which may indirectly lead to an accident.

Moreover, even if the back cover can be removed without using tools such as a screwdriver, separate parts are required.
When the bank cover was removed, the parts sometimes got lost somewhere because they were not integrated with the back cover or the lamp body.

The purpose of the present invention was made in view of the above-mentioned drawbacks, and includes a locking piece provided on the lamp body so as to protrude rearward from the surface of the back cover, and a corresponding locking piece provided on the back cover or the lamp body. a stopper portion formed on the locking piece or the stopper portion; and a hinge portion formed on the locking piece or the stopper portion, and formed so as to press the back cover toward the lamp body when the locking piece is locked to the stopper portion via the hinge portion. To provide a vehicular lamp in which a back cover can be attached to and detached from a lamp body by a so-called hand-touch operation without using any tools by having a structure including a protrusion.

Hereinafter, details of the present invention will be explained using examples shown in the drawings.
