Patent ID: 7798718

Claim:
A rolling element accommodating belt for a linear guide apparatus which comprises: a guide rail having a rolling element guiding face; a slider arranged relatively movable to the guide rail and comprising: a load rolling element guiding face opposite to the rolling element guiding face to constitute a rolling element track path together with the rolling element guiding face; a pair of direction converting paths communicating to both ends of the rolling element track path; and a rolling element return path communicating to the pair of direction converting paths; a plurality of rolling elements circulating while rolling within an endless circulation path defined by the rolling element track path, the pair of direction converting paths and the rolling element return path; and a guide groove provided internally along the endless circulation path, the rolling element accommodating belt comprising: a plurality of spacer portions interposed between the rolling elements adjacent to each other; coupling arms coupling the spacer portions with one another and hanging over outwardly from end faces of the spacer portions so as to be guided by the guide grooves; and rolling element accommodating portions defined by the spacer portions and the coupling arms and accommodating the rolling element individually so as to align the rolling elements in an arrangement direction in which the rolling element aligns within the endless circulation path, wherein the spacer comprises an inward abutting face abutting on the rolling element so as to prevent the rolling element from moving to inner diameter side of the endless circulation path; and wherein the spacer further comprises an other abutting face abutting on the rolling element, the other abutting face permitting the rolling element to move toward outer diameter side of the endless circulation path in the rolling element track path.
