PROBLEM TO BE SOLVED: To provide a braking device that can restrain variations in natural frequencies of a disk rotor.SOLUTION: The braking device comprises: a cylindrical drum part 1 including a fixed part 4 fixed to a wheel; a disk rotor 2 connected to the outer peripheral side of the drum part; shoes 31 arranged on the inner peripheral side of the drum part; and an actuator 32 for pressing the shoes against an inner peripheral surface 3a of the drum part. The actuator keeps the shoes in contact with the inner peripheral surface at the time of braking. |
