Abstract:
There is provided a motor including a rotor having a magnet fixed to the outer periphery of a rotor main body, a spindle for rotatably supporting the rotor via the rotor main body, a first bearing unit provided at one end side of the rotor in a longitudinal direction of the spindle, and a second bearing unit provided at the other end side of the rotor in the longitudinal direction of the spindle. The first bearing unit slidably contacts the spindle with a set clearance, and the second bearing unit includes an elastic bearing unit slidably contacting the spindle in a state of being elastically pressed against the spindle. When the first bearing unit is defined as a bearing unit at the one end side in the longitudinal direction of the spindle, the elastic bearing unit is configured to be located as a bearing unit at the other end side.
