Abstract
A motor includes a facing member having a part facing a rotary shaft, a seal member having elasticity, and an annular member supporting the seal member. Magnets are disposed on the outer circumferential surface of the rotary shaft. Coil units are disposed on the inner circumferential surface of the annular member. The annular member is rotated by a magnetic force in the same direction as the rotary shaft when the rotary shaft rotates. The seal member rotates with the annular member at a rotation speed that is lower than a rotation speed of the rotary shaft.
