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 lead groove provided on one of the outer peripheral surface of the piston rod or the inner peripheral surface of the penetrating portion of the piston rod; and a lead groove provided on the other of the outer peripheral surface or the inner peripheral surface of the piston rod; and a ball that is rotatably fitted into the piston rod, and the linear motion of the piston is converted into a rocking motion of the piston rod by rolling of the ball along the lead groove. An oscillating cylinder device characterized in that the cross section of the lead groove is formed in a substantially V-shape, and the ball is biased toward the lead groove by a biasing means. 2. The oscillating cylinder device according to claim 1, further comprising adjusting means for adjusting the oscillating angle of the piston rod. 3. The oscillating cylinder device according to claim 2, wherein said adjusting means is formed by stroke adjusting means for adjusting the stroke of said piston rod relative to the linear motion.
