Claims

[Scope of utility model registration request]

Inside a cylinder with one end closed and the other end open, there is a disc-shaped sliding body that is in close contact with the inner wall of the cylinder and moves in response to fluid pressure sent into the cylinder, and a disc-shaped sliding body that moves by being pushed by the movement of the sliding body. A disc-shaped or ring-shaped ratchet and a protruding rod that is similarly pushed and moved through the ratchet by the movement of the sliding member and protrudes from the opening of the cylinder are fitted so as to be movable in the axial direction, and the above-mentioned In the case of a disc-shaped or ring-shaped ratchet, its outer diameter is smaller than the inner diameter of the cylinder, and the length between the end of one face and the end of the other face diagonally passing through the axis is longer than the inner diameter of the cylinder. A disk or ring which is also large in size, and a projection is provided on a part of the outer peripheral edge side of the surface of the disk or ring on the protruding rod side, and this projection is brought into contact with the protruding rod. Output support.
