Claim:
1. An oscillating actuator comprising: an actuator main body having a shaft which is configured to oscillate and rotate about an axis in a predetermined range of angle by an action of a compressed air; and a fixing plate for fixing the actuator main body to a load device, wherein the fixing plate is not part of the actuator main body and is an independent element separate from the actuator main body, wherein the actuator main body and the fixing plate are connected together by a connection mechanism so as to relatively change each other's position in the rotation direction of the shaft so that an oscillation start position of the shaft is changed by displacement of the actuator main body and the fixing plate relative to each other, and wherein the connection mechanism includes a plurality of screw holes that are disposed on a plate mounting surface of the actuator main body in the circumferential direction about the axis at specific intervals, a plurality of screw insertion holes that are disposed on the fixing plate in the circumferential direction about the axis at specific intervals, and a plurality of connection screws that are inserted into the screw insertion holes and are threaded into the screw holes, and wherein the number of screw holes is an integer multiple of the number of the screw insertion holes, and the number of connection screws is equal to the number of screw insertion holes.
