PROBLEM TO BE SOLVED: To obtain a low-vibration and low-noise motor unit and a low-vibration and low-noise lens barrel without reducing motor torque, and to thereby obtain a camera that does not record unwanted noise. SOLUTION: The motor unit includes: a motor, a lead screw rotated by the motor, a fixing frame for holding the motor and the lead screw through an end bearing, and a thrust spring installed in the motor. At least any of the lead screw, end bearing, fixing frame, and thrust spring is formed of vibration damping material. COPYRIGHT: (C)2008,JPO&INPIT
