PROBLEM TO BE SOLVED: To provide a lamp that is less expensive and permits high degree of freedom in designing, in relation to a bulb fixing structure that utilizes a bayonet engagement. SOLUTION: By rotating a bulb fixture 32 around an optical axis Ax at a predetermined angle, with three bayonet engaging legs 32cA, 32dA, 32eA formed in the circumferential direction of the bulb fixture 32 inserted into three recessed slots 30c, 30d, 30e formed in the circumferential direction of the inside peripheral surface of an annular wall 30 of a reflecting mirror 18 from the back side in the direction of the optical axis Ax of the reflecting mirror 18, respectively, the bayonet engaging legs 32cA, 32dA, 32eA are made to engage in a bayonet engaging manner with bayonet engaging protrusions 30cA, 30dA, 30eA formed on the recessed slots 30c, 30d, 30e, respectively. Thus the bayonet engagement on inside periphery of the annular wall 30 makes a slide mold unnecessary in molding the reflecting mirror and allows the bulb to be fixed regardless of the bulb fixing location in relation to the reflecting mirror 18. |
