Abstract: A cylinder main body is provided with a first port that supplies fluid pressure to a first cylinder chamber, and a second port that supplies fluid pressure to a second cylinder chamber. The fluid pressure supplied to the first port is transmitted to the first cylinder chamber via a clearance formed in a double tube structure.

Abstract: A coupling device includes a fluid pressure cylinder fixed to the first member. The fluid pressure cylinder includes a cylinder main body, a first piston and a second piston each reciprocally movable with respect to the cylinder main body along a first direction, and a biasing member that drives each of the first piston and the second piston to one side in the first direction. The cylinder main body has a first cylinder chamber that drives the first piston to the other side in the first direction, and a second cylinder chamber that is formed to be separated from the first cylinder chamber and that drives the second piston to the other side.

Abstract: The fluid clamp apparatus includes: a sliding piston member that vertically partitions its cylinder bore; first and second fluid pressure operation chambers; a fluid passage that, during an upward light-load stroke of the piston member, causes the back pressure in the second fluid pressure operation chamber to be received by the output rod to advance the output rod; a force multiplying mechanism that, during a heavy-load stroke of the piston member, multiplies the force acting on the piston member and transmits this force to the output rod; and a link mechanism that, during unclamping lowering operation of the piston member, links together the output rod and the piston member after lowering by a predetermined stroke amount.
