<P>PROBLEM TO BE SOLVED: To certainly and stably remove dust attached to a piston rod in a fluid pressure cylinder to prevent ingression into a cylinder body. <P>SOLUTION: An end part of a cylinder tube 12 constituting the fluid pressure cylinder 10 includes a rod cover 14, and the piston rod 18 is inserted through a rod hole 42 of the rod cover 14. The rod cover 14 includes: a scraper 58 through an installation groove 50 formed in the inner circumferential face; and an annular ring body 66 installed inside the scraper. The scraper 58 is cross-sectionally formed in a U shape from a resin material having self-lubricity, and the ring body 66 formed in a cross-sectionally circular shape from an elastic material is inserted thereinside. An inner cylinder part 64 of the scraper 58 slidingly contacts with the outer circumferential face 18a of the piston rod 18, and the inner cylinder part 64 is pressed on the outer circumferential face 18a side by elastic force of the ring body 66. <P>COPYRIGHT: (C)2012,JPO&INPIT |
