PURPOSE:To perform assembling without giving stress to a circuit board. CONSTITUTION:For a case body 32, a lamp socket part 35 and a lighting circuit arranging section 37 are formed integrally. For a circuit board 34, lighting parts are connected, and also a lighting circuit, which has a connection 73 to be electrically connected to the terminal 51 of a lamp socket 35, is formed. In the lighting parts storing chamber 63 of a lighting circuit arranged part 37, a slit 65 for heat radiation is made to pierce the board to the inner and outer faces, and also a support projection 70 to support the circuit board is made. A locking claw 66 to be locked with the slit for heat radiation of the case body 32 is made in a cover 33 for the case body 32. The circuit board 34 arranged on the openings of the terminal storing chamber 48 and the lighting parts storing chamber 63 of the case body 32 is caught and held with the cover 33 and the supporting projection 70 of the case body 32. Accordingly, the incorporation of the circuit board 34 can be made easily. The heat of the lighting circuit part is radiated from the slit 65 for heat radiation of the case body 32. |
