ブレーキ装置。A piston fitted in a cylinder so as to be able to reciprocate in the axial direction is moved in one direction by the biasing force of a spring to bring the brake into operation, and the piston is moved in the other direction by fluid pressure against the biasing force of the spring. In a negative operation type fluid pressure brake device having a structure in which the brake is released by movement, a holding member is provided in a fitting hole penetrating the peripheral wall of the cylinder so as to be able to move forward and backward in a direction orthogonal to the axis of the cylinder by operation from the outside. is fitted onto the peripheral wall of the piston,
A retaining portion is provided that matches the fitting hole when the piston is moved to the brake release position, and the engaging end of the holding member is engaged with the retaining portion to maintain the brake release state. A negative actuation type fluid pressure brake device characterized in that:
