Zusammenfassung:A plurality of guide shafts which are disposed parallel to an input/output shaft (a first input/output shaft, a second input/output shaft) are assembled in a case body which holds a cylinder in which first and second piston sets, move reciprocally. A first guide bearing, which abuts both side surfaces of a first piston body and receives only lateral pressure generated by the reciprocal movement, and a second guide bearing, which abuts both side surfaces of a second piston body and receives only lateral pressure generated by the reciprocal movement, are assembled coaxially and separated in an axial direction on each guide shaft.
