Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a reflector mounting structure in a vehicle lamp, particularly a two-wheeled vehicle lamp.

(Prior Art) To attach a reflector to a conventional motorcycle lamp, for example, as shown in FIG. It is disposed on the upper surface of b', and a boss c' formed on lens c is brought into contact with the upper part thereof. Then, connect the tapping screw d to the boss c' of the lens c and the reflector a.
Insert it into the hole a″ provided in the protruding piece a′ of the housing b.
The structure was such that it was tightened and fixed to the boss part b' of the.

(Problems to be Solved by the Invention) In the conventional installation, the projecting piece a' of the reflector a and the boss part c' of the lens c are self-tapped to the boss part b' of the housing b using a tapping screw d. If the housing b is made of a resin material, the threaded part between the boss part b' of the housing b and the tapping screw d may be damaged if the housing b is repeatedly tightened. The boss portion b' of the housing b itself had a large amount of waste, and the sink mark after molding of the housing b was conspicuous and the appearance was poor.

The present invention attempts to solve these conventional problems.

(Means for Solving the Problems) As a means for solving the above problems, the present invention provides a housing in which protrusions having a U-shaped cross section are formed facing each other at the opening end, and an L-shaped rising portion. and an L-shaped cut-and-raised piece provided on the other side of the L-shape so that a square nut can be press-fitted between the two and the hook can be fixed. The main feature is that the reflector has a projecting piece at its open end, and a screw that passes through the boss of the lens and screws into the nut to fix the projecting piece of the reflector.

(Function) The above configuration eliminates the need for the boss part of the housing, prevents breakage of the boss part, and reduces the wall thickness of the boss part, thereby preventing sink marks during housing molding, and making it possible to securely attach the reflector. I can do it.

(Embodiment) Hereinafter, the present invention will be explained in detail with reference to the illustrated embodiment. Reference numeral 1 denotes a housing, which has a concave groove 1a formed on the outer periphery of the opening end, and an inner wall of the housing having a protrusion in the shape of a cross section. The pieces 1b are formed to face each other, and the interval A between the upper pieces 1b' between the protruding pieces 1b is slightly larger than the interval B between the lower pieces 1b'' (see Fig. 2). 2 is a reflector. An L-shaped projecting piece 2a is formed in the opening, a cut-and-raised claw piece 2b and a hole 2c are formed in the horizontal part, and the tip 2d is bent to stand up. The height C of the raised tip 2d is slightly longer than the width D of the groove 1c of the protrusion 1b of the housing 1 (see FIG. 2). Between the projecting pieces 2 of the reflector 2
A is fitted from above onto the lower piece 1b'' between the protruding pieces 1b, and the square nut 3 is inserted between the protruding pieces 2a.
Press fit between the projections 1b so that the hooks are fixed to the cut and raised claws 2b. At this time, the tip 2d of the protruding piece 2a formed on the reflector 2 is tightly fitted between the upper piece 1b' of the protruding piece 1a of the housing 1, thereby positioning it in the left-right direction. Next, the outer peripheral edge 4a of the lens 4 is inserted into the groove 1a of the housing 1.
The reflector 2 is brought into close contact with the reflector 2 through the gasket 5, and the boss portion 4b formed on the inside thereof is attached to the reflector 2.
The screw 6 is inserted into the hole 2c formed in the horizontal part of the protruding piece 2a of the reflector 2 and the boss part 4b of the lens 4 whose axes match, and the screw 6 is inserted into the square nut 3. The reflector 2 and lens 4 are fixed to the housing 1 by screwing. Reference numeral 7 denotes a socket attached to the reflector 2, and an insulator 9 is disposed in the cylindrical portion of the housing 1 via a coil spring 8. Note that 10 is a valve, and 11 is a power supply cord.

(Effects of the invention) As explained above, according to the invention, a cut-and-raised claw piece formed at the open end of the reflector is provided between the protruding pieces having a cross-sectional shape of [ ] which are formed opposite to the open end of the housing. At the same time as arranging an L-shaped protrusion, a square nut is press-fitted between the protrusions of the housing so that the hook is fixed to the cut and raised claw of the reflector, and a screw inserted through the boss portion of the lens is screwed into the square nut. The projecting piece of the reflector is fixed in place by being fitted into the housing, so the reflector can be securely fixed without rattling or loosening even after repeated tightening, and there is no need for a boss to screw the screw into the housing. As a result, the amount of waste in the housing is reduced, and there are no sink marks after molding the housing, resulting in excellent effects such as improved appearance.
