PROBLEM TO BE SOLVED: To prevent a motor assembly from falling off from a chassis.SOLUTION: A rotating lamp unit comprises: a light source 15b arranged at a chassis; a motor assembly 18 which has a drive motor 30 and is assembled to the chassis 13; a rotating reflector 17 which has a drive force transmission part 26 to which drive force of the drive motor is transmitted, is rotated by the transmission of the drive force of the drive motor to the drive force transmission part, and reflects light which is emitted from the light source; an energization spring 33 which energizes the motor assembly to a direction in which an output shaft of the drive motor is pressed against the drive force transmission part; and a regulation cover 34 in which a movement regulation part 34c for regulating the movement of the motor assembly to a direction opposite to an energization direction by the energizing spring is arranged, and which is attached to the chassis. This structure allows the movement regulation part of the regulation cover to regulate the movement of the motor assembly in the direction opposite to the energization direction due to the energizing spring to prevent the motor assembly from falling off from the chassis. |
