Abstract:
1. A rolling element accommodating tool for rotatably accommodating a plurality of rolling elements at predetermined intervals, the rolling element accommodating tool being placed along an endless circulation path along which the rolling elements circulate in a linear motion device provided with the endless circulation path and comprising a rail element and a linear moving element that moves linearly relative to the rail element; wherein the rolling element accommodating tool has a main body configured from spacers individually provided between adjacent rolling elements, and connecting parts oriented in a direction orthogonal to the direction in which the spacers are aligned, protruding on both sides of the rolling elements in a state of accommodating the rolling elements, and serially connecting the spacers; reinforcing films having the same length in the longitudinal direction as the connecting parts being contained within the connecting parts; and the reinforcing films being formed at large widths in the positions of the spacers in the longitudinal direction of the main body as compared to other portions in the longitudinal direction of the main body.
