PROBLEM TO BE SOLVED: To provide a laser device capable of adjusting appropriately the distance between a laser light source and a collimating lens, at a low cost. SOLUTION: When an operator applies moment force to an operating member 107, a lens holder 104 moves to the position shown by a dotted line under the circumstances, the ball 106c of a plunger 106 is pushed in so that the lens holder 104 may be prevented from wrenching and may be made possible to rotate. On the other hand, when the operator stops operating the operating member 107 by the elastic force of a spring 106b, the ball 106c of the plunger 106 pushes back the lens holder 104 to the position (position without an optical-axis gap) shown by a solid line. Consequently, an optical-axis gap can be controlled. COPYRIGHT: (C)2005,JPO&NCIPI
