PROBLEM TO BE SOLVED: To provide a high-durability, high-reliability optical scanner for a vehicle. SOLUTION: This optical scanner for a vehicle comprises a laser diode 55 and lenses 34, 35, 36 for sweeping a beam of light from the laser diode 55, in a predetermined first direction. The laser diode 55 is moved in the optical axis direction by a plate spring placed in a holder 51 so that the size of the beam of projected light is varied. COPYRIGHT: (C)2009,JPO&INPIT
