材である。 Fig. 1 is a perspective view showing an embodiment of this invention, Fig. 2 is a perspective view of the side seal member of the dustproof seal, and Fig. 3 is a front view of the end cap shown in Fig. 1 with the end cap partially cut away. 4, 5, and 6 are cross-sectional views showing modified examples of the side seal member, FIG. 7 is a perspective view of a linear guide device equipped with a conventional dustproof seal, and FIG. 8 is a cross-sectional view showing a modification of the side seal member. FIG. 2 is a perspective view of a conventional dustproof seal. In the figure, 1 is the guide rail, 2 is the slider, 2A is the slider body, 3 is the ball rolling groove (of the guide rail), 5 is the end cap, 6A is the bolt insertion hole,
6B is a plane part, 8a is a seal projection, 13 is a nipple, 10 and 20 are dustproof seals, 21 is a side seal member, 23 is a notch part, and 25 is a top seal member.

Claims

[Scope of utility model registration request]

A guide rail that has a bolt insertion hole for fixing to the base and has axial ball rolling grooves on both sides and extends in the axial direction, and a ball that faces the ball rolling groove of the guide rail. Dust-proofing of a linear guide device comprising a slider having rolling grooves and supported by the guide rail so as to be movable in the axial direction through the rolling of a large number of balls inserted into the ball rolling grooves. a seal, comprising a seal protrusion that slides into contact with the ball rolling groove surface on the side surface of the guide rail;
and a side seal member that is attached to the axial end of the slider and has a notch at a location corresponding to the opening of the bolt insertion hole on the upper surface of the guide rail, and a side seal member that is attached to the axial end of the slider, and both sides of the opening of the bolt insertion hole of the guide rail. The linear guide is formed of a top seal member that is directly fixed to the inner surface of the slider so as to face the flat part extending in the axial direction, and prevents foreign matter from entering the ball rolling groove. Equipment dust seal.
