A main body having an internal space, a movable body that is movably inserted into the internal space to partition a pressure chamber and a pressureless chamber, and a part of the movable body that penetrates the main body. In the brake device, the brake equipment is provided with a rond extending to the outside, and a pressure fluid is supplied to the pressure chamber to move the movable body and actuate a wheel brake device via the rond. consists of two members, a male and a female, screwed together, and one of the two members on the side of the wheel brake device outside the main body is prevented from rotating, while the other member is is rotatable with respect to one member that is prevented from rotating and the movable body, and the other rotatable member is rotated by a shoe clearance adjustment mechanism in response to excessive movement of the movable body. The brake actuator is configured to increase the overall length of the rond, and the shoe clearance adjustment mechanism is provided in an internal space of the main body. 2. The brake actuator according to claim 1, wherein the shoe clearance adjustment mechanism is constituted by each component of 11th order A to C. A lever whose middle portion is pin-coupled to the main body, one end is located at a distance from the movable body by a distance equivalent to a predetermined shoe clearance, and the other end is engaged with the other rotatable member. 0 (B) When the brake of the wheel brake device is released,
A return spring that returns the lever to its original position before applying the brake. (C) Interposed between the other end of the lever and the other rotatable member, the other member is moved by an amount corresponding to the excessive movement of the movable body only when the rond moves back to release the brake. One-way clutch mechanism that rotates.
