Claims

[Claims for Utility Model Registration] 1. A piston housed in a cylinder chamber in a direct-acting actuator partitions the cylinder chamber into a right-hand chamber and a left-hand chamber, and the right-hand chamber and the left-hand chamber are separated. A seal member for sealing is provided on the piston, and a piston rod extending from the piston in the axial direction is swingable integrally with respect to the swing axis of the swing actuator and in the axial direction. The compound actuator is connected to the swing shaft so as to be movable in a straight line along the axis, and the compound actuator includes a linear seal part that seals a linear sliding part of the piston, and a swing seal part that seals a swing sliding part of the piston. A piston seal mechanism, characterized in that the seal member is formed by integrating the two together. 2. The seal member is formed by integrating a bumper portion that buffers the impact force of the piston at a stroke end, the straight-travel seal portion, and the rocking seal portion with each other. piston seal mechanism. 3. A composite actuator comprising the piston seal mechanism according to claim 1 or 2.
