Claims

[Scope of utility model registration request]

a guide rail that extends in the axial direction and has a ball rolling groove on its outer wall; a slider that is movably straddled over the guide rail and has ball rolling grooves on the inner walls of both sleeves; The slider includes a large number of balls that are rotatably interposed between the ball rolling groove of the slider and the ball rolling groove of the guide rail, and an end cap that is attached to the end of the slider and forms a circulation path for the balls. A dustproof seal used in a linear guide device, comprising a metal plate attached to the end cap, and a rubber body joined to the metal plate with a protrusion protruding from the inner edge of the opening of the metal plate toward the guide rail. In addition, the tip of the inner edge of the rubber body is formed with a thin sliding lip portion that is in contact with the guide rail, and a thin sliding lip portion that precedes the sliding lip portion and is not in contact with the guide rail through a slight gap. A dustproof seal for a linear guide device characterized by having a thick non-sliding edge portion.
