ABSTRACT:
A cylinder locking device comprises a thick cylindrical brake member whose inner diameter is slightly smaller than the outer diameter of a piston rod to be locked. The cylindrical brake member is disposed in a casing and fitted on the piston rod, and has a slit opening formed axially therein. Two receive rollers are disposed oppositely and rotatably on both margins of the slit opening. An actuator having a tapered portion is disposed in the casing. The locking of the piston rod is released when the tapered portion is forced in between the receive rollers to expand the cylindrical brake member. When the actuator is not in actuation, the piston rod is strongly gripped and locked by the elasticity in the diameter-decreasing direction of the cylindrical brake member.
