    • PROBLEM TO BE SOLVED: To provide a motor with built-in brake, which has a built-in brake in the motor and is capable of obtaining stop holding torque when power is not applied. SOLUTION: The motor with built-in brake consists of a motor comprising a casing 1, a magnet 7 mounted on the inner wall of the casing 1, a rotor 8 placed opposite to the magnet, and a shaft 9 that supports the rotor. The shaft 9 of the rotor 9 is installed in the casing 1 so that the shaft can be rotated and slid in the axial direction, and is provided with a movable-side braking member 18. The casing 1 is provided with a fixed-side braking member that is abutted against the movable-side braking member 18 and thereby performs braking action. A brake is applied to the rotor 8, when energized, by the center of the rotor in the axial direction being displaced relative to the magnetic center of the magnet 7 in such a direction that the movable-side braking member 18 goes away from the fixed-side braking member 19, and, when not energized, by the movable-side braking member 18 being pressed against the fixed-side braking member 19 by centripetal force between the magnet 7 and the rotor 8.
