<P>PROBLEM TO BE SOLVED: To structure a dust seal system by pressure-inserting a dust seal without giving a bad influence on sealability. <P>SOLUTION: This dust seal system 20 comprises a spacer 23, which houses a rod 12 in a tube 11 in the state of protruding a tip of the rod 12 outside and which is used for a linear moving device for moving the rod 12 and the tube 11 relatively to each other and which surrounds the periphery of the rod 12 in an opening end of the tube 11, and a dust seal 24 held in the inner surface of the spacer 23 through a base part 24a thereof in the state of bringing a single dust lip part 24b thereof in slide-contact with the peripheral surface of the rod 12. In the spacer 23, the peripheral surface 23g thereof is structured to be inclined so that outer dimension thereof is gradually increased from a tip surface, which is positioned on a tip side of the rod 12, to at least a part corresponding to the peripheral range of a base part 24a of the dust seal 24. <P>COPYRIGHT: (C)2009,JPO&INPIT |
