The two brake members 6.7 are rotated so as to open the upper part and close the lower part against the biasing force of the coil spring 14 with the outer peripheral part supported by the support member 8.9, and the outer peripheral part of the brake member 6.7 Since the center of the circle containing the piston rod is offset downward from its inner circumference, that is, the center of the cross-sectional circle of the piston rod 5, a slight gap is created between the brake member 6.7 and the piston rod 5, and the brake is released. .

That is, when the fluid pressure inside the fluid pressure actuator 20 is released, the force that was pushing the two pistons 22.23 outward disappears, so that the biasing force of the coil spring 14 is applied to the brake member 6.7.
act to rotate the brake member 6.7 along the inner periphery of the support member 8.9 in the direction in which its upper portion closes. Then,
The center of the circle that includes the inner circumference of the support member 8.9, that is, the outer circumference of the brake member 6.7, is the inner circumference of the support member 8.9, that is, the piston rod 5.
Since the piston rod 5 is eccentrically downward from the center of the cross-sectional circle, the piston rod 5 is locked between the brake members 6 and 7 from both sides, and the piston rod 5 is locked without applying any shearing force or rotational force to the piston rod 5. I can do it.

The brake can lock the piston rod without generating shearing force or rotational force on the piston rod, preventing deformation and wear of the piston rod and its bearing, and making it possible to reliably stop the piston rod. Furthermore, since the brake member is constantly biased in the locking direction by the spring, even if the fluid pressure source or power supply of the actuator is suddenly turned off due to an accident, the piston rod is immediately locked by the biasing force of the spring, ensuring safety.
