<P>PROBLEM TO BE SOLVED: To provide a motor capable of being downsized in an axial direction and a radial direction even when a slide bearing can be moved in an axial direction smoothly. <P>SOLUTION: A motor 1 comprises: a rotary shaft 2; a driving magnet 3; a driving coil 5; a case body 17 covering an outer peripheral surface of the driving coil 5; a slide bearing 7 supporting an anti-output side end part of the rotary shaft 2 and being movable in an axial direction of the rotary shaft 2; and a bearing holder 8 holding the slide bearing 7 on an inner peripheral surface 8a movably in the axial direction. The bearing holder 8 is fixed to an anti-output side end surface 17b of the case body 17, and the whole of the bearing holder 8 is arranged outside the case body 17. A bearing holding surface 17c connected with the inner peripheral surface 8a of the bearing holder 8 is formed to the case body 17. A part of the slide bearing 7 is arranged inside the case body 17. The slide bearing 7 is held movably in the axial direction by the inner peripheral surface 8a of the bearing holder 8 and the bearing holding surface 17c. <P>COPYRIGHT: (C)2013,JPO&INPIT |
