Claims

[Scope of Claim for Utility Model Registration] (1) A movable member supported by a guide means so as to be movable in a straight line; a feed screw passing through the movable member and extending in the moving direction of the movable member; a nut member that is permanently attached and screwed together with the feed screw; and an elastic member that is attached to both end faces of the moving member in the moving direction, and the elastic member has an inner space surrounding the outer periphery of the feed screw. A slide mechanism characterized in that the inner space has an insertion hole located on the opposite side of the moving member and has a diameter substantially the same as the outer diameter of the feed screw, and the inner space of the elastic member is connected to a pressure reducing means. . (2) a guide rail provided to extend in a straight line; a moving member having a guided portion slidably engaged with the guide rail; and a moving member moved by a moving means; and a moving direction of the moving member. an elastic member attached to both end surfaces of the guided part, the elastic member being located in an inner space surrounding the outer periphery of the guide rail or a part thereof, and on a side of the inner space opposite to the guided part. A slide mechanism comprising an insertion hole having substantially the same cross-sectional shape as a guide rail, and wherein the internal space of the elastic member is connected to a pressure reducing means.
