VEHICULAR SLIDE DEVICE, AND ROLLING ELEMENT CIRCULATION UNIT

WIPO Patent Application WO/2017/163866

A1

This vehicular slide device includes a first rail, a second rail, working surfaces, and rolling element circulation units. The second rail is supported on the first rail so as to be capable of relative movement in the extension direction of the first rail. The working surfaces are provided to the first rail, and face the second rail. The rolling element circulation units are provided with: a plurality of rolling elements which come into contact with the working surfaces, and roll; and annular storage portions which enable the plurality of rolling elements to roll and circulate while the plurality of rolling elements are in an annularly arranged state. The rolling element circulation units are provided between the first rail and the second rail. The annular storage portions include: regions including contact surfaces which come into contact with the working surfaces via the rolling elements; and regions including non-contact surfaces which do not come into contact with the working surfaces via the rolling elements. The annular storage portions are formed from at least two materials having different rigidities. The regions including the contact surfaces are formed from a material having a higher rigidity than the regions including the non-contact surfaces.
