Abstract: One example of a sliding device that can sufficiently reduce a separation phenomenon is disclosed. The sliding device includes a fixed rail, a movable rail, a fixed-side hook, an engagement hook, and a reinforcing hook. The fixed rail is configured to be fixed to a vehicle. To the movable rail, the seat body is attachable. The movable rail is slidable with respect to the fixed rail. The fixed-side hook is configured to be fixed to the vehicle. The engagement hook is provided to the movable rail. The engagement hook is engageable with the fixed-side hook, and is formed by a first plate material curved approximately into a letter J or U shape. The reinforcing hook overlaps with the engagement hook in a thickness direction of the first plate material. The reinforcing hook is formed by a second plate material curved approximately into a letter J or U shape.

Abstract: Disclosed is one example of a sliding device in which a movable rail can be inhibited from being largely deformed even when a load such as a compressed load acts on the movable rail. The sliding device includes a fixed rail, a movable rail, and a load receiving portion. The fixed rail is configured to be fixed to a vehicle. To the movable rail, the seat body is attachable. The movable rail is slidable with respect to the fixed rail. The load receiving portion extends from a fixed rail side toward a movable rail side. The load receiving portion is configured to receive a load directed from the movable rail toward the fixed rail in conjunction with the movable rail when the load acts on the movable rail.

Abstract: A seat slide device is fixed to the floor of a vehicle and includes lower rails, each of which includes a front range and a rear range and extends forward and backward, and an upper rail supporting a movable seat and capable of moving over the lower rails. The seat slide device also includes a lock portion, a stopper, and a stopper-releasing operating portion. The lock portion selectively restricts movement of the upper rail on the lower rails at a plurality of positions. The lock portion is provided to the upper rail. The stopper stops movement of the upper rail before the upper rail advances from either one of the front range and the rear range, past this range, to the other range. The stopper-releasing operating portion enables movement of the upper rail when the upper rail has been stopped by the stopper.
