The second drive unit 24 urges the respective pistons 24B such that the housing 24A, the pair of pistons 24B displaced by power from the first drive unit 20, and the pair of pistons 24B are displaced in the direction away from each other. And 24C. In the present embodiment, the first friction member 12A is attached to one piston 24B, and the second friction member 12B is attached to the other piston 24B.

  By operating the lever G1 of the brake operating device G, hydraulic oil in the cylinder G2 is supplied to the first drive unit 20 via the first hydraulic hose H1, and the piston 20B is moved to the first space 20E. 2 Move in the direction approaching the connecting portion 20D. Then, the hydraulic oil in the second space 20F is supplied to the second drive unit 24 through the second hydraulic hose H2, and the first friction member 12A and the second friction member 12B are at the first standby position SP1 or the second standby position. The pair of pistons 24B is displaced so as to move from SP2 to a contact position in contact with the rotating body F1. Thus, hydraulic pressure acts on the brake device 10 in response to the input to the brake operation device G, and the brake device 10 brakes the rotating body F1. On the other hand, when the input to the brake operation device G is released, the first friction member 12A and the second friction member 12B move from the contact position to the first standby position SP1 or the second standby position SP2 by the biasing force of the biasing member 24C. The piston 24B is displaced to move, and the hydraulic oil in the housing 24A is returned to the first drive unit 20 via the second hydraulic hose H2.

Note that one of the pair of pistons 24B and one of the first friction member 12A and the second friction member 12B may be omitted. That is, the rotary body F1 may be braked by only one of the first friction member 12A and the second friction member 12B. Alternatively, one of the first friction member 12A and the second friction member 12B may be fixed, and only the other may be moved.

  In a state where the friction member 12 (here, the first friction member 12A and the second friction member 12B) is disposed at the first standby position SP1, the electric drive unit 14 moves the piston 20B in a direction approaching the first connection portion 20C. As a result, the second space 20F is enlarged. In this case, the hydraulic oil in the housing 24A is returned to the first drive unit 20 via the second hydraulic hose H2, and the biasing force of the biasing member 24C causes the friction member 12 to move from the first standby position SP1 to the second standby position SP2. The piston 24B is displaced so as to move to the On the other hand, in a state where the friction member 12 is disposed at the second standby position SP2, moving the piston 20B in the direction approaching the second connection portion 20D by the electric drive unit 14 increases the size of the first space 20E. In this case, the hydraulic oil in the second space 20F is supplied to the second drive unit 24 via the second hydraulic hose H2, and the piston is moved so that the friction member 12 moves from the second standby position SP2 to the first standby position SP1. 24B is displaced. Thus, when the electric drive unit 14 is driven, the friction member 12 is moved from one of the first standby position SP1 and the second standby position SP2 to the other.
