Claims

[Scope of utility model registration request]

a lower rail fixed to the floor side; an upper rail slidably fitted to the lower rail; a lock plate provided on the lower rail side with lock teeth carved thereon; a engraved memory rack; a pipe rotatably attached to the upper rail;
A handle shaft rotatably inserted through the pipe, a lock lever fixed to the pipe and released from engagement with the lock plate during walk-in, and a lock lever that locks the pipe into engagement with the lock lever and the lock plate. a first spring that is biased to rotate in the same direction; a lift lever that is fixed to the handle shaft and that comes into contact with the lock lever and rotates together when the seat slide is unlocked; a gear arm whose rotating end is pivotally supported by the lift lever; a gear rotatably attached to the gear arm and capable of meshing with the memory rack; and a gear connected to the gear and with which the lock lever is locked. a drum-shaped memory disk having a locking portion and a spiral groove with the locking portion as one end and on which the lock lever can slide; and a rotation biasing force in a direction to engage the memory disk with the lock lever. A seat truck comprising a second spring and a third spring that biases the handle shaft to rotate in a direction in which the gear engages with the memory rack.
