Abstract
A motor is provided with a chucking device enabling attachment and detachment of a disk-shaped storage medium. In the motor, a turntable forming a portion of the chucking device is disposed axially above a rotor holder. The turntable has a placement portion on which the storage medium is placed. An inner recess is formed on an outer surface of a shaft between a position at which the rotor holder is fitted and another position at which the turntable is fitted. An outer recess is formed to radially face the inner recess and is concave away from a center axis. Adhesive is placed in the inner recess and the outer recess.
