Description of the Related Art In a conventional seat adjuster device, a lock mechanism is provided on each of the left and right seat rails to improve safety, and a normal operation lever mounted on one seat rail side cannot be operated. In general, the locking mechanism on the seat rail side is operated, and at the same time, the locking mechanism on the other seat rail side is transmitted via the first pull wire. In addition, a seat adjuster is also known, which allows the seat to move beyond a normal adjustment range in order to bring the seat cushion and the seat back into a fully flat state. In this type of device, a reclining device provided separately is also known. The operation means interlocking with the like is connected to the lock mechanism of the seat rail on the side where the normal operation lever is not attached, and when the operation of the operation means operates the lock mechanism portion on the connected side, A configuration in which the lock mechanism is transmitted to the other seat rail side via the two pull wires is known.

ない（図１及び図３参照）。First, when adjusting a normal seat, the operation lever 6 is at the position shown in FIG. 2, and the locking claw pieces 8 and 12 are both in the locking position where they engage the locking plates 10 and 11. At this time, in order to adjust and move from the lock position, the operation lever 6 is operated and the second link 1 fixed to the operation lever 6 is operated.
When the first link 17 is moved in the range of the A angle by the locking portion 19a of 9, the pull wire 16 connected to the first link 17 operates the first link 17 by the operation amount of the operation lever 6, and the operation is performed by this operation. The pawl pieces 8 and 12 unlock the locking plates 11 and 10. In this case, since the pulling amount is small, the outer side (upper rail 2a side) operates only in the range of B angle, so that the stopper 11a provided on the locking plate 11 cannot be overridden and can be moved only within the range of M up to the stopper 11a. No (see FIGS. 1 and 3).

reference). Therefore, when the reclining is tilted forward and the walk-in operation is performed, the first lever 17 that fits on the manipulation lever 6 and rotates while the manipulation lever 6 remains in the same state causes the manipulation piece 17a to move through the walk-in cable 18 when the reclining is tilted. When is pulled, the first link 17 integrated with the operation piece 17a moves to the C angle range. Therefore, by this operation, the locking claw piece 8 is released from the locking plate 10 and the first link 17 is largely actuated to increase the working angle of the locking claw piece 12 through the pull wire 16 connected to the first link. Works,
The locking claw piece 12 can get over the stopper 11a and can be slid up to N, and can be moved forward and fully flat (see FIG. 4). That is, it is possible to achieve full flatness by changing the operation amount (see FIG. 5C).
