A cylinder locking device for a fluid pressure cylinder in which two brake members (6, 7) are formed by dividing axially into two a thick cylinder having outer and inner circumferences in eccentric relation, the division being made in the region of maximum thickness and the region of minimum thickness. A piston rod (5) of a fluid pressure cylinder (1) is slidably fitted within the inner circumferential portion of the nearly semi-cylindrical brake members (6, 7). Support members (8, 9) rotatably support the outer circumferential portions of the two brake members (6, 7). A spring (14) is arranged to bias the brake members (6, 7) in a direction to lock the piston rod (5), and an actuator (20) can rotate the brake members (6, 7) in a direction to release them from their locking condition against the biasing force of the spring (14). |
