However, such a conventional technique has a structure in which a projection formed on one lamp is inserted into a cylindrical portion formed on the other lamp. Therefore, it is necessary to accurately position the tip of the protruding piece and the cylindrical portion, and the positioning operation is difficult, resulting in a decrease in work efficiency. In addition, since the protrusion is prevented from coming off from the cylindrical portion by the connecting portion formed in another portion, if there is a dimensional error in the forming position of the protruding portion or the cylindrical portion, the connecting portion is prevented from coming off. There is a possibility that the alignment of the lamps may be affected, and both lamps may not be connected at the connecting portion. Instead of forming the connecting portion, a claw portion may be formed at the tip of the protruding piece, and the claw portion may be configured to be engaged with the end of the cylindrical portion. This increases the resistance when inserting the protruding piece into the cylindrical part, and requires a large force to insert the protruding piece into the cylindrical part. There is also a possibility that it will.

The present invention focuses on such prior art, and provides a vehicle lamp connecting structure that does not require difficult positioning and does not require a large force.
