Claims

[Scope of utility model registration request]

A lower rail fixed to the floor panel of the vehicle body, an upper rail fixed to the seat cushion frame and fitted to the lower rail so as to be slidable in the longitudinal direction of the seat, and a top rail provided on the lower rail side and arranged in the longitudinal direction of the seat. a lock plate that is rotatably supported on the upper rail and that engages with the engaging portion with a spring force to prevent the seat cushion from moving back and forth; and a lock plate that is rotatable on the upper rail. and a release lever supported so as to be slidable in the front-rear direction of the seat between the first position and the second position, a cam holder pivotally supported on the upper rail, and a cam holder rotatably supported on the cam holder. , and when the release lever is brought to the first position and rotated, the rotation of the release lever is not transmitted to the cam holder, and the release lever is moved to the second position. and a connecting means for connecting the release lever and the cam holder so that when the cam holder is brought to the position and rotated, the cam holder rotates relative to the upper rail as the cam holder rotates. 1 position and rotated upward, the lever contacts the lock plate and rotates it, disengaging the plate from the engagement portion and moving the release lever to the second position. The relative position of the release lever and lock plate is set so that the lever does not come into contact with the lock plate when the release lever is brought into position and rotated upward, and the cam contacts the contact portion and the protrusion. When the cam holder rotates as the release lever rotates, the contact portion engages with one of the engaging portions, and the cam rotates around this engaging portion and slides in the front-rear direction with respect to the cam holder. A seat adjuster for a vehicle, wherein the protrusion contacts a lock plate engaged with another engagement part and pushes it out of the engagement part.
