Abstract
A coupler is provided inside an engaging hole of a piston yoke, which is connected to pistons. A slider is installed on an upper portion of the coupler through a coupler-insertion hole. An engaging member, provided at a lower portion of the coupler, is inserted into the engaging hole so as to be displaceable by a slight amount in the widthwise direction of a cylinder tube. The coupler is inserted into the coupler-insertion hole of the slider, so that the coupler-insertion hole is slidable with respect to curved surface sections of the coupler.
Claims13
A displacement difference-absorbing mechanism for a cylinder apparatus including a main cylinder body and a belt that closes a slit extending in an axial direction, and wherein a piston is displaceable in the axial direction under an action of a pressure fluid supplied from a pressure fluid inlet/outlet port, said displacement difference-absorbing mechanism comprising:
- a displacement member displaceable in the axial direction along said main cylinder body;
- a displacement-transmitting member connected to said piston, which transmits displacement of said piston to said displacement member;
- and
- a displacement difference-absorbing member provided between said displacement member and said displacement-transmitting member, which has a perpendicular surface disposed substantially perpendicular to a displacement direction of said displacement member, and a curved surface having a constant radius about a center of a vertical line,
- wherein said displacement difference-absorbing member is arranged such that said perpendicular surface is fitted to one of said displacement member and said displacement-transmitting member, and said curved surface is fitted to another one of said displacement member and said displacement-transmitting member.
