PCT No. PCT/JP97/02154 Sec. 371 Date Apr. 14, 2000 Sec. 102(e) Date Apr. 14, 2000 PCT Filed Jun. 23, 1997 PCT Pub. No. WO97/49931 PCT Pub. Date Dec. 31, 1997This invention relates to a sliding guide apparatus for, for example, a linear guiding apparatus, curved guiding apparatus, swiveling bearing or the like for infinite sliding motion, and more particularly to a sliding guide apparatus wherein an end-present rolling element chain for supporting a linear motion or rotary motion is inserted in a full track. The sliding guide apparatus comprises a track rail having a rolling path for rolling elements extending in the length direction of the sliding guide apparatus, a moving body which contains a loaded rolling path facing the aforementioned rolling path and an unloaded rolling path which circulates the rolling elements from one end to the other end of the loaded rolling path and moves along the aforementioned track rail, and a plurality of rolling elements which roll between the moving body and track rail while being loaded with a load and circulate in a full track composed of the loaded rolling path and unloaded rolling path of the aforementioned moving body. The rolling elements are disposed in line at predetermined intervals in a single or plurality of flexible connecting belts such that they can roll freely and incorporated in the full track of the sliding member together with the connecting belts. The connecting belts circulate with the balls in the full track of the sliding member while both end portions thereof are opposed to each other.
