The optical scanner (1) comprises: a motor (2) having an rotor shaft (4); a rotor (11) being attached to the rotor shaft (4); a tilt mirror (3) having an inclined reflective surface (3a) and being attached to the rotor shaft (4) together with the rotor (11); and a bearing section (9a, 9b) being provided to a stator housing (7) and capable of rotatably holding the rotor shaft (4). The rotor (11) and the tilt mirror (3) are prohibited from detaching from and rotating with respect to the rotor shaft (4). A recessed part (3g), through which the rotor shaft (4) is penetrated, is formed in the tilt mirror (3). An elastic member (14), which always biases the tilt mirror (3) toward the rotor (11), is provided between a retainer section (12) and an inner bottom part of the recessed part (3g). |
