<p>PROBLEM TO BE SOLVED: To surely retain origin return even in a failure of a control circuit, in a light distribution variable type headlight device.SOLUTION: The light distribution variable type headlight device includes: a housing in which a stopper part is formed; a light source fixed at the housing; a holder for holding a projector lens and rotating around the light source; a first lever in which a gear is formed on an outer periphery and which is fixed at the holder; a second lever in which a contact piece is formed and which rotates around the holder; a first coil spring in which one end is locked to the first lever and the other end is locked to the second lever; a second coil spring in which one end is locked to the second lever and the other end is locked to the housing; and a motor mounted with a driving gear. Winding directions of the first coil spring and the second coil spring are opposite to each other, and the contact piece of the second lever and the stopper part of the housing are in contact with each other during non-conduction time of the motor.</p> |
