摘要： A slide apparatus for a vehicle includes first and second rails and a rolling element circulation unit including first and second cases and a plurality of rolling elements accommodated within a receiving portion that includes first and second annular receiving portions accommodating the rolling elements annularly arranged in a rolling and circulating manner. The second case includes elongated bores connected to the first and second annular receiving portions in a state where the second case is mounted at the second rail. A portion of the rolling elements is exposed from the elongated bores while being inhibited from disengaging from the elongated bores. The rolling elements exposed from the elongated bores make contact with an operating surface of the first rail and inner surfaces of the first and second annular receiving portions, and roll and circulate in association with a relative movement between the first and second rails.

摘要： A vehicle slide device is provided, which can adjustably move the second rail along the first rail without play therebetween in a front-rearward direction with a long adjustment stroke. In the vehicle slide device according to the invention, since a plurality of rolling elements annularly arranged in the attaching portion formed at the second rail are always in contact with the operating surface of the attaching portion and the operating surface of the first rail when the second rail moves relative to the first rail in a front-rearward directions, the play of the second rail relative to the first rail in up-down and right-left directions can be eliminated. Further, since the plurality of rolling elements roll and circulate at the attaching portion, the second rail can smoothly move in a front-rearward direction along the first rail.
