<P>PROBLEM TO BE SOLVED: To provide a sealing arrangement which restrains a foreign matter, etc. from outside, from being bitten while restraining a sliding resistance from being increased. <P>SOLUTION: The sealing arrangement 1 is installed on an annular groove 201 provided in one member of a shaft 300 relatively mutually reciprocating in axial direction and a housing 200 including a shaft hole into which the shaft 300 is inserted, and seals the annular gap formed between the shaft 300 and the shaft hole provided on the housing 200. The sealing arrangement is provided with: a first sealing portion 11 which slidably contacts on a surface of the other member; and a second sealing portion 15 which slidably contacts on surface of the other member in an anti-sealing target area side A rather than the first sealing portion 11 when the relatively reciprocating state of one member and the other member is in such a state that the other member shifts relative to one member in direction from an anti-sealing target area side A toward a sealing target area side O and does not come into contact with the surface of the other member when the relatively reciprocating state of one member and the other member is in other state. <P>COPYRIGHT: (C)2010,JPO&INPIT |
