Claims

[Claims for Utility Model Registration] (1) A drive rack provided in the main body and reciprocated by fluid pressure, a pinion meshed with the drive rack, one end of which is inserted into the main body, and an internal shaft. a cylinder that is engaged with one end of the pinion inserted in the direction of the pinion and thereby oscillates with the pinion; a piston that is housed inside the cylinder so as to be movable in the axial direction; The other end of the cylinder is connected and protrudes through a closing member that closes the other end of the cylinder, and forms a sliding pair with the cylinder, so that the cylinder can be moved without being restrained from relative displacement in the axial direction. A swinging cylinder comprising a piston rod that swings together with the piston rod. (2) The rocker according to claim 1 of the utility model registration, characterized in that the piston rod passing through the closing member has a polygonal cross section, so that the piston rod and the cylinder form a sliding pair. Cylinder. (3) a support member that is engaged with the outer end of the piston rod; and a support member that is provided parallel to the piston rod, one end of which is slidably inserted into the wall surface of the cylinder, and the other end of which is inserted into the support member. 2. The swinging cylinder according to claim 1, wherein the piston rod and the cylinder form a sliding pair by an engaged guide bar. (4) A driven rack that reciprocates following the swinging of the pinion is meshed with the pinion, and by regulating the stroke end of the driven rack, the pinion swings through the cylinder. The swinging cylinder according to claim 1, wherein the swinging angle of the piston rod is adjusted. (5) A fluid supply/discharge device formed to pass through the pinion in the axial direction, one end of which opens into a fluid chamber formed on one side of the piston within the cylinder, and the other end of which is provided in the main body. a fluid passageway communicating with the port; and a fluid chamber formed in the wall surface of the cylinder in the axial direction, with one end opening into a fluid chamber formed in the cylinder on the other side of the piston;
A request for registration of a utility model characterized in that the piston rod reciprocates by supplying and discharging fluid into the cylinder through a fluid passage whose other end communicates with a fluid supply and discharge port provided in the main body. The swing cylinder according to the range 1 above.
