That is, the dust-proof cover 6 has one end fixedly attached to the side seal 5 of the slider 2 and the other end fixedly attached to the end of the guide rail 1, and expands and contracts in accordance with the movement of the slider 2. 1a and both side surfaces 1b, 1b (in particular, the rolling element rolling groove 3) can be completely covered at all times, and the dustproof effect is great, but the maximum extension length of the dustproof cover depends on the movement stroke of the slider 2. It is necessary to manufacture the dustproof device while taking into consideration the relationship between the length and the minimum shrinkage length. Therefore, it is necessary to prepare a dustproof device corresponding to each specification of the linear motion guide bearing, it is difficult to secure a large number of lots, the price is high, and the manufacturing lead time tends to be long. I can't.

A slider having a rolling element rolling groove facing the rolling element rolling groove of the guide rail on its inner surface and a plurality of sliders rotatably inserted in the two rolling element rolling grooves facing each other. The present invention relates to a dust proof device for a linear motion guide bearing having a rolling element, and includes a dust proof cover that covers the upper surface and both side faces of the guide rail and is expandable and contractible in the axial direction. One end of the dust proof cover is fixed to the end of the slider. The other end is movable along the guide rail through a slide guide member having a concave portion having a shape in close contact with the cross-sectional shape of the guide rail.

移動するすべり案内部材により排除される。In the dustproof device having the above structure, one end side fixed to the end of the slider moves together with the slider as the slider of the linear guide bearing moves. On the other hand, the other end side does not move and stays in a fixed position on the guide rail while the slip resistance of the slide guide member is larger than the tension of the dustproof cover. As a result, a predetermined range in the longitudinal direction of the upper surface and both side surfaces of the guide rail remains covered with the dustproof cover.
When the dustproof cover extends and its tension becomes larger than the slip resistance of the slide guide member, the slide guide member at the other end moves as the slider and the dustproof cover move. Therefore, an exposed portion that is not covered with the dustproof cover is formed on the upper surface and both side surfaces of the guide rail. Therefore, the foreign matter adhering to the exposed portion is eliminated by the slide guide member which simultaneously moves back when the slider moves back.

合と同等の防塵能力が発揮されることになる。When the slider 2 moves on the guide rail 1, the dustproof cover 6 of the dustproof device 12 expands and contracts with the movement (see FIG. 2). When the slider 2 moves in the extending direction of the dustproof cover 6 (FIG. 2A), the side fixed to the end of the slider 2 moves together with the slider. On the other hand, the other end side engaged with the guide rail 1 does not move while the slip resistance of the slide guide member 14 is larger than the tension of the dust cover 6, and remains at a fixed position on the guide rail 1. Therefore, the upper surface 1a and both side surfaces 1b, 1b of the guide rail remain covered with the dustproof cover 6 in a predetermined range in the longitudinal direction. When the dustproof cover 6 is further extended and its tension becomes larger than the slip resistance of the slide guide member 14, the slide guide member 14 moves together with the slider 2 and the dustproof cover 6. Therefore, the exposed portion A which is not covered with the dustproof cover 6 on the upper surface 1a and both side surfaces 1b, 1b of the guide rail.
Occurs (FIG. 3 (a)). Foreign matter such as dust adheres to the exposed portion A. However, when the slider 2 moves in the return direction, the extended dust-proof cover 6 begins to contract, and when the slide guide member 14 is pushed and moves toward the fixed position of the end portion (FIG. 3 (b)), The attached foreign matter is removed by the slide guide member 14 functioning as a seal (FIG. 3C), and as a result, the dustproof capability equivalent to that of the dustproof cover 6 fixed at both ends is exhibited.

きるという実用上の大きな効果を生じる。Since the dustproof device 12 of the present embodiment operates as described above, not only can it exhibit a dustproof function equivalent to that of the conventional one that constantly covers the upper surface and both side surfaces of the guide rail. Even if the stroke length of the slider 2 of the linear motion guide bearing 11 is changed, it can be automatically and easily dealt with. Therefore, it is not necessary to prepare multiple types of dustproof devices according to the specifications of the linear motion guide bearing, especially the slider stroke length, mass production of a large number of lots is possible, and standard inventory can be easily secured. Therefore, it has a great practical effect that it can be provided at a low cost and in a short delivery time.

This is different from the first embodiment in that a mandrel 16 made of a steel plate or the like is attached in advance to the mandrel 16 and a seal-shaped slide guide member 14 is assembled to the mandrel 16 by using screws 17. By using such a cored bar 16, there is an advantage that the existing inexpensive side seal 5 for the slider can be diverted to the slide guide member 14. Further, the mandrel 16 is provided with a flexible sliding guide member 14 formed of a material made of rubber or synthetic resin containing a lubricant in advance.
Can also be assembled as a reinforcing material.
