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 notch hole of a predetermined size formed in the lower rail so as to face the roller rolling surface thereof, and corresponding to the notch hole forming portion on the outer surface side of the lower rail. a fulcrum pin that is slidably and rotatably supported in a position where the fulcrum pin is slidably and rotatably oriented with its axial direction perpendicular to the axial direction of the lower rail; is an engaging portion that can protrude onto the roller rolling surface of the lower rail, and an engaging position where the engaging portion projects onto the roller rolling surface through the notched hole and a peripheral edge of the notched hole. a rotary lever that can be positioned in two positions, including a release position where the lever comes into contact with the roller and is prevented from protruding toward the rolling surface of the roller; a biasing means that always biases the fulcrum pin in its axial direction so as to correspond to the peripheral edge of the notched hole, and always biases the rotary lever toward the engagement position; A stopper that restricts further biasing rotation of the rotary lever when the engaging portion protrudes above the roller rolling surface of the lower rail, and a stopper that slides the fulcrum pin against the biasing means. 1. A slide device for a vehicle seat, comprising: a slide regulating mechanism having a slide regulating mechanism and an operating section for rotational operation.
