That is, this type of composite type vehicular lamp has a structure in which the two lamp bodies are integrated with each other, and the joining brackets protruding from the side wall of the lamp body by insert molding or the like are brought into contact with each other, and the two brackets are joined together. Although tightening with bolts and nuts was generally used, not only the number of parts is large, the manufacturing cost rises, the assembly work is complicated and the workability deteriorates, and the assembly position is finely adjusted. There is a problem such as a defective appearance after assembly due to a defect.

Therefore, as a conventional assembly structure for a vehicle lamp, the lamp bodies of adjacent vehicle lamps can be assembled by one-touch positioning with certainty. , Various things have been proposed.

For example, the conventional structure shown in FIG.
A fixing piece 52 having a fastener 51 and a fixing piece 54 having a boss hole 53 are projectingly provided on a side wall of a lamp body 50 of one of the vehicle lamps, and a side wall of a lamp body 55 of the other vehicle lamp, It has a structure in which a locking pin 56 that is inserted into and engaged with the fastener 51 and a boss 57 that is inserted into and positioned in the boss hole 53 are provided so as to be parallel to the opposing position.

Therefore, when assembling the two lamp bodies 50 and 55, the boss 57 is inserted into the boss hole 53, and the locking pin 56 is inserted into the fastener 51, so that the fastener 51 is integrated by the elastic force of the fastener 51. Type vehicle lighting device.

[0006]

However, according to the configuration of the conventional vehicular lamp having the above-described configuration, the one-touch insertion of the locking pin 56 into the fastener 51 facilitates the assembling work, while the locking pin is provided. 56 is fastener 5
Even if it is not completely inserted with respect to No. 1, since a temporary assembly state is formed, the levels of the front lens surfaces of the two lamp bodies 50, 55 are different, or the levels are the same when assembled. However, there may be a problem that the locking pin 56 comes out of the fastener 51 during use.

The present invention was conceived in view of the above problems, and the number of parts is small and the assembling work can be easily performed by one-touch operation, and the assembling position can be reliably determined.
After assembly, the mounting positions of both lamp bodies will not shift,
An object of the present invention is to provide a composite type vehicular lamp having a new assembly structure between adjacent lamp bodies.

[0008]

In order to achieve the above object, a vehicular lamp according to the present invention is a vehicular lamp having a structure in which a plurality of adjoining lamp bodies are integrated with each other. Male and female engaging structures that are integrally formed with the respective lamp bodies on the facing side walls and mutually engage with each other, and integrally formed with the respective lamp bodies on the upper wall of the adjacent lamp body, and the male and female engaging structures are engaged. In the combined state, the first and second locking pieces are formed by forming axial holes so that they are coaxially stacked, and the first and second locking pieces are coaxially polymerized. The gist is that an assembling structure including a fastener bolt penetrating both shaft holes is configured.

In the above-mentioned assembly structure, the engaging direction of the male and female engaging structures formed on the side wall of the lamp body and the engagement of the first and second locking pieces formed on the upper wall of the lamp body by the fastener bolts. It is preferable that the directions are orthogonal to each other.

Further, a detent locking end is formed at the tip of the insertion portion of the engaging male structure formed on the side wall of one of the lamp bodies constituting the male and female engaging structure, and the relative distance between the other adjacent lamp bodies. It is also possible to adopt a structure in which a bending edge is formed on a part of the shaft hole engaging edge of the engaging female structure formed on the facing side wall.

[0011]

According to the above construction, the male and female engaging structures integrally formed with the lamp bodies of both vehicle lamps are inserted and engaged, and the first and second locking pieces matched by this operation. It is possible to complete the assembling work so that the front lenses of the two lamp bodies are flush with each other by pressing the fastener bolts into the shaft holes that have been drilled, and to construct a composite type vehicle lamp.

When assembling the two lamp bodies,
When the assembling position is incomplete and the male and female engaging structures are not engaged at the predetermined position, the relative positions of the first and second locking pieces are displaced horizontally and both shaft holes are moved vertically. Because they do not match
It becomes impossible to press-fit the fastener bolt from such a state.

Moreover, since the fitting characteristics of the male and female engaging structures can be improved and the adjacent lamp bodies can be surely integrated, the accuracy of assembling the composite type vehicle lamp to the vehicle body can be improved. .
