BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of an automobile headlamp according to the present invention will be described below with reference to FIGS. The headlamp 10 of this embodiment is divided into a headlamp body 11 (FIG. 2) and a side lamp 12 (FIG. 1), and the side lamp 12 can be attached and detached at a side portion of the headlamp body 11. This allows the bulbs in the headlamp 10 to be replaced.

In this embodiment, as shown in FIG. 1, a pair of upper and lower parts (FIG. 1, arrow H) are provided at appropriate positions on the inner surface of the side lamp 12.
Claw pieces 13 are provided. Preferably, each claw piece 13 attached to the side lamp 12 in a cantilever manner is arranged substantially in the front-rear direction (FIG. 1, arrow Fr) and is formed of an appropriate synthetic resin material so that the tip portion is appropriately formed. It can bend. Further, the claw piece 13 has an end portion 14 to be fitted with a locking hole of the headlamp body 11 which will be described later. The extension portion 1 having a predetermined length is further provided on the tip side of the end portion 14.
5 is formed. The extension 15 is slightly tapered so that it can be easily inserted into the locking hole on the headlamp body 11 side.

The headlamp body 11 has a pair of upper and lower engaging holes 16 into which the claw pieces 13 fit (FIG. 2). Further, the locking hole 1 is provided so as to correspond to the extension portion 15 of the claw piece 13.
