Claims

[Scope of utility model registration request]

An adjustment plate having a plurality of adjustment grooves in the rail direction is fixed to the upper rail, which is movably fitted to the lower rail fixed to the vehicle body side and fixed to the seat side. An operating shaft having a handle is rotatably mounted between the pair of shaft support pieces, and a locking member having a locking pawl that can selectively engage each of the adjustment grooves is attached to the operating shaft. It is fitted so that it can rotate integrally with the operating shaft and is movable in the axial direction, and is always urged by a spring in the direction in which the locking pawl engages with the adjustment groove, while the locking pawl is attached to the lower rail. has an engagement hole into which the locking pawl is removably inserted, is rotatable between an engaging position and a non-engaging position with respect to the locking pawl, and is always biased to the engaging position by a spring; A lock plate is provided on the front side of the lock plate, which is rotated to the disengaged position in conjunction with the forward folding of the seat bag. The memory mechanism is characterized in that a cam surface is formed to rotate and guide the lock plate in the disengagement direction against the biasing force of the spring when pressed by the locking pawl of the lock member. Comes with seat adjustment device.
