摘要： A biasing spring is interposed between a coupling plate and a covering section while being compressed from its natural length. The biasing spring biases, by its resilient force, a lens unit toward a −Z side to bring a surface of the lens unit at the −Z side into contact with an abutment portion of a fixing frame section. When a temperature of an actuator is equal to or lower than a predetermined temperature, a biasing force of the biasing spring surpasses a force generated in the actuator, and thus the lens unit is not moved. When the actuator is heated up to a temperature equal to or higher than the predetermined temperature, the lens unit is continuously moved in the +Z direction. Thereby, movement of a lens due to a change of an environmental temperature can be prevented.
