Abstract
A motor may include a rotation shaft, a drive magnet, a drive coil, a case body covering the drive coil, a slide bearing supporting the rotation shaft and movable in an axial direction, and a bearing holder holding the slide bearing movably in the axial direction through an inner peripheral face. The bearing holder is fixed to an opposite-to-output side end face of the case body and an entire bearing holder is disposed on an outer side of the case body and the case body has opening part having a bearing holding face for slidably supporting the slide bearing together with an inner peripheral face of the bearing holder. A part of the slide bearing is disposed in an inside of the case body and the slide bearing is slidably held by the inner peripheral face of the bearing holder and the bearing holding face of the case body.
Claims19
A motor comprising:
- a rotation shaft;
- a drive magnet which is fixed to the rotation shaft;
- a drive coil which is disposed on an outer peripheral side of the drive magnet;
- a case body which covers at least a part of an outer peripheral face of the drive coil;
- a slide bearing which supports an end part on an opposite-to-output side of the rotation shaft and is movable in an axial direction of the rotation shaft;
- and
- a bearing holder which holds the slide bearing movably in the axial direction through an inner peripheral face of the bearing holder;
- wherein the bearing holder is fixed to an opposite-to-output side end face of the case body and an entire bearing holder is disposed on an outer side of the case body;
- wherein the case body is structured with an opening part having a bearing holding face for slidably supporting the slide bearing together with an inner peripheral face of the bearing holder;
- wherein a part of the slide bearing is disposed in an inside of the case body;
- and
- wherein the slide bearing is held by the inner peripheral face of the bearing holder and the bearing holding face of the case body so as to be movable in the axial direction.
