摘要： A rack and pinion type oscillating actuator includes a pair of parallel sliding holes formed in a body, rack members having racks slidably fitted in the pair of sliding holes, respectively, an output shaft having a pinion engaged with the racks is rotatably supported by bearings arranged in the body, and an output shaft is rotated by reciprocating of the rack members on the basis of supplying and discharging of compressed air. An end member closing one opening in the sliding hole is arranged in the body, a piston extending in an axial direction from the end member within the sliding hole is inserted in a closed-end cylindrical hole provided in the rack member so as to be relatively displaced in an axial direction, and a fluid passage, in which one end portion communicating with a pipe port provided in the end member and another end communicating with the closed-end cylindrical hole is provided in the piston.
