To smoothly operate a switching lever by forming a lever sliding surface between a lamp tool body and the switching lever in a room lamp for a vehicle whose lamp tool body has a plurality of flat conductive plates.

An extending part 36 extending in a planar direction is integrally made at a conductive plate 7c and is formed between a luminaire body 2 and a switching lever 10 such that it surrounds a shaft 13 for rotatably supporting the switching lever 10, thereby forming a lever sliding surface. A contact member 12 is fixed to the free end of a leaf spring 31 supported at one end by the switching lever 10 and is pressed to a contact part. Since the extending part 36 is made the sliding surface of the switching lever 10, friction resistance is made small without putting the switching lever 10 into direct contact with the surface of the luminaire body 2 and the switching lever 10 is smoothly operated.
