ABSTRACT:
In a bulb fixing structure, a bulb mounting hole portion has an inner wall and an outer wall that stand concentrically with the bulb mounting hole. A fixture has a dish-like shape having a peripheral wall portion in which interlocking grooves are formed. Each interlocking groove is partially defined by at least one claw portion. The fixture can be readily fixed to the bulb mounting hole portion with a high fixing strength by inserting the peripheral wall portion into the space between the inner and outer walls so that the claw portions of the interlocking grooves bite into rib walls that stand between the inner and outer walls. When the fixture is thus fixed, the inner and outer walls cover the peripheral wall, protecting it from an external force.
