調整装置。[Claims for Utility Model Registration] A main body holding a laser light source is provided with a lens barrel having a collimating lens that converts the light emitted from the laser light source into a beam so as to be movable forward and backward with respect to the laser light source. An adjustment screw orthogonal to the forward/backward direction of the lens barrel is screwed together, and a tapered surface is formed on the lens barrel to convert movement of the adjustment screw in the axial direction into movement of the lens barrel in the forward/backward direction; A laser beam optical system characterized in that a biasing means is provided between the main body and the lens barrel for biasing the lens barrel in a direction in which a tapered surface of the lens barrel comes into contact with the tip of the adjustment screw. Focus position adjustment device.
