PROBLEM TO BE SOLVED: To facilitate and ensure and assembling of a lamp housing to a lens. SOLUTION: A width W2 at a front end side of an assembling of a fitting protrusion 101 is larger than a width W1 at a rear end side of an assembling. As a result, when a lamp housing 100 and a lens 200 are assembled, a guide action for sliding the fitting piece 201 on a surface of the fitting protrusion 101 becomes large and an assembling of the lamp housing 100 to the lens 200 is facilitated. Since a width W1 at a fitting step portion at a rear end side of an assembly of the fitting protrusion 101 is smaller than the width W2 at a front end of the assembly, a fitting margin of the fitting step portion 102 with an fitting through hole 202 is small. Even if the lamp housing 100 and the lens 200 are surely assembled, a release of an fitting state of the fitting step portion 102 with the fitting through hole 202 is simple.
