Claims

[Claims for Utility Model Registration] 1. A brake device that fixes a piston rod of a fluid pressure cylinder by applying a frictional force thereto, the brake device surrounding the piston rod and fixing the piston rod in the axial direction by a spring. a fluid chamber for moving the piston in an axially opposite direction against the spring by introducing fluid; a fluid chamber surrounding the piston rod and supporting the spring of the piston rod; a brake member configured to apply a frictional force between the piston rod and the piston rod when biased by the brake member; and a brake member having one end fixed to the piston and extending in an axial direction opposite to the biasing direction of the spring. A brake for a fluid pressure cylinder, further comprising: a threaded member that penetrates a main body member that is fixedly provided to the main body of the brake device, and a nut member that is threadedly engaged with the threaded member. Device. 2. The piston is provided with a tapered surface that serves as a chair toward the end, and the brake member is in sliding contact with the tapered surface and contracts toward the center in the radial direction by the bias of the spring of the piston. A brake device for a fluid pressure cylinder as set forth in claim 1 of the utility model registration claim, which is constructed as follows.
