Claims

[Claims for Utility Model Registration] 1. A cylinder body, a piston provided in a cylinder chamber within the cylinder body so as to be movable along the axial direction, and a piston protruding from at least one end surface of the piston along the axial direction. a piston rod, wherein a linear motion of the piston is converted into an oscillating motion of the piston rod, the first flow path extending along the axial direction of the piston rod; , the first fluid port is formed by opening the first flow passage on the outwardly projecting end side of the piston rod, and the first fluid port is opened outside the cylinder body and is connected to the first fluid port through the first flow passage. a second fluid port that is in communication with the first fluid port; an attachment that is removably provided on the outwardly projecting end of the piston rod and extends along the transverse axis of the piston rod; and a second fluid port that is opened on the free end of the attachment; It is characterized by comprising a third fluid port to which a predetermined fluid pressure device is connected, and a second flow path formed in the attachment and allowing the first fluid port and the third fluid port to communicate with each other. Oscillating cylinder device. 2. The oscillating cylinder according to claim 1, wherein a plurality of working fluid pressure ports for actuating the piston and the second fluid port are respectively opened in a concentrated manner at one end of the cylinder body. Device. 3 A flow path having a ring-shaped cross section is formed between the outer peripheral surface of the inner cylinder tube and the inner peripheral surface of the outer cylinder tube, which are arranged coaxially with each other, and is connected to one of the working fluid pressure ports and the piston. 3. The oscillating cylinder device according to claim 2, wherein one of the fluid chambers of the cylinder chambers partitioned by the cylinder chamber is communicated with each other via the flow path.
