Claims

[Scope of utility model registration request]

A lower rail that is fixedly arranged on the vehicle body floor, and an upper rail that is fixedly arranged on the seat side and is slidable in the axial direction with respect to the lower rail by a roller that is rotatably inserted between the lower rail and the lower rail. A sliding device for a vehicle seat, comprising: a lower rail;
a rod which is disposed so as to be movable forward and backward in a direction substantially orthogonal to the axial direction of the lower rail and which is always biased by an appropriate biasing means so as to protrude toward the roller rolling surface of the lower rail; a first regulating means for regulating at least further protrusion in a release position where the head is located outward from the roller rolling surface; and the regulating action of the first regulating means is released and the rod protrudes. A slide regulating mechanism is provided, comprising a second regulating means that engages with the rod at an engagement position where the head of the rod protrudes a predetermined amount above the roller rolling surface to regulate further forward and backward movement. A vehicle seat sliding device characterized by:
