Abstract:
PURPOSE:To reliably feed grease to a shaft portion and a cylinder portion by providing grease feed nonreturn device grips at suitable places of covers mounted at both ends of a cylinder. CONSTITUTION:When a piston 3 is returned to the terminal portion, a through hole 17 coupled to a grease feed nonreturn device grip 11 is aligned with an O-groove 16 of a piston portion, so that on feeding grease, grease can be fed to the interior of the O-groove 16 of the piston portion. Accordingly, when the piston 3 is moved forward and backward, grease in the O-groove 16 of the piston portion is supplied to O-rings 14, 15 to be supplied to the inner wall surface of a cylinder 1. Further, for feeding grease to a shaft portion 4, grease is supplied by a grease pump from a grease feed nonreturn device grip 10 mounted on a cover 7 disposed on the cylinder 1.
