PURPOSE: To provide a lighting fixture for a car free of restriction on the position to form an opening for bulb replacement where a back cover is mounted with a bayonet engagement. CONSTITUTION: This lighting fixture for a car is composed of a lamp body molded with a first die for molding the outside of lamp body and a second die for molding the inside of the lamp body and having a front face left open and a back face furnished with a circular opening 100B for bulb replacement and a back cover 200B mounted at the opening 100B with bayonet engagement and located about the circumferential direction. The opening 100B is arranged to open in the direction inclining with respect to the die opening direction, and the outward extension (223) on the side with back cover 100B abuts to a stopper 110 on the side with lamp body when the back cover 100B is rotated in the bayonet engagement direction so that the back cover 200B is located about the circumferential direction of the circular opening 100B. According to this arrangement in which opening 100B for bulb replacement is formed by the use of split dies, no undercut will be produced when the lamp body is formed, and it is possible to widen the degree of freedom for the position where the opening for bulb replacement is to be provided.
