A light source fixing structure of a lamp is provided. The structure includes a lamp body having a mounting base, a light source having a disc flange, and a set spring elastically contacting the disc flange to fix the disc flange to the mounting base. The lamp body includes a latch protrusion to lock the set spring. The set spring includes a support portion supported on the lamp body, a manually operable lock operating portion, and an elastically contacting portion. An operation of the lock operating portion in one direction causes the elastically contacting portion to elastically contact the back surface of the disc flange and generates an elastic reaction force in a direction different from the one direction. The elastic reaction force urges the lock operating portion toward the latch protrusion and causes the lock operating portion to engage with the latch protrusion. |
