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: A balancer mechanism for a rotating shaft is capable of preventing deviation of the axis of the rotating shaft. The balancer mechanism (20) has an assistance torque generation means (21) for generating an assistance torque; the assistance torque generation means (21) includes a cam member (24) fixed to the rotating shaft (4), a cam follower member (25) and a gas spring (27); and a reaction force generation means (22) is provided for generating, by the biasing force of the gas spring (27), a balancing moment that cancels out a tilting moment that tilts the rotating shaft (4) around a bearing member (9) in a direction to separate it from the assistance torque generation means (21).

Abstract: A clamping device increases the diameter of a gripping assembly that is inserted into a hole in a workpiece and thus grips the inner circumferential surface of the hole, and particularly relates to such a clamping device that is adapted so that, in the vicinity of a scraper, no clearance occurs between the gripping assembly and a clamp rod, and the scraper. The clamping device is capable of enhancing the durability of a scraper, reducing the amount of pressurized air consumed by blowing, and ensuring the strength of a clamp rod against pulling and so on.

Abstract: A clamp device has a grip member for gripping the inner peripheral surface of a hole in a workpiece, a clamp rod having a tapered shaft portion that is fitted into and engaged with the grip member, a hydraulic cylinder for driving the grip member and the clamp rod forwards and backwards in the axial direction, and a main body member to which the above elements are mounted. A tubular cylindrical main body portion projecting upwards is provided at the center portion of an upper half portion of the main body member. The outer diameter of this tubular main body portion is set less than or equal to three times the outer diameter of the grip member in the unclamped state, and, in the unclamped state, the upper half portions of the grip member and the tapered shaft portion are made to project outward from the upper end of the tubular main body portion.
