Abstract
A collimator lens unit in which an aperture limit stop formation member and a collimator lens are integrally disposed in a cylindrical member is inserted in a lens-barrel hole of the module casing so as to be reciprocatable in an optical axis direction, and a light-emitting unit is fixed in the lens-barrel hole, with an optical axis of a light source aligned with an optical axis of the collimator lens. A long hole through which an adjust pin is penetrated so as to be reciprocatable in the optical axis direction is formed in a peripheral sidewall of the lens-barrel hole, and a fitting portion in which the adjust pin is fit is formed in an outer peripheral surface of the cylindrical member. On an inner peripheral surface of the lens-barrel hole, at a position opposed to the fitting portion, bearing portions in contact with the outer peripheral surface of the cylindrical member are formed.
