Abstract
A motor may include a rotation shaft whose output side includes a feed screw, a permanent magnet fixed to an outer peripheral face on an opposite-to-output side of the rotation shaft, a stator having a drive coil disposed on an outer peripheral side with respect to the permanent magnet, a bearing which supports an end part on the opposite-to-output side of the rotation shaft, a bearing holder which is fixed to the stator and slidably holds the bearing in the axial direction, and an urging member which urges the bearing to an output side. The bearing may be formed with a protruded part which is protruded to an outer side in a radial direction of the rotation shaft, and the protruded part may be disposed between an end face on the opposite-to-output side of the permanent magnet and an end face on the output side of the bearing holder.
