  The problem to be solved by the present invention is that when the underframe of the seat cushion is assembled to the upper rail of the slide rail, the underframe of the seat cushion is attached to the slide rail even if the operating lever is provided at a position where it abuts the lock lever. It is designed to be easily assembled to the upper rail to improve workability.

According to the first aspect of the present invention, a substantially middle bent portion is mounted on the underframe plate surface by a support shaft, a pressing roller is provided on one end side, an operation lever is connected to the other end side, and the roller side is provided by a spring. An underlever of the seat cushion is provided with an unlocking actuating lever that has an approximately L-shaped spring biased upward,
A substantially middle abdominal part is mounted on the plate surface of the upper rail with a support shaft, and a lock tooth that can be engaged or removed with a plurality of lock holes along the longitudinal direction of the lower rail is pinned to one end side, and a pressure roller Is provided on the upper rail side of the slide rail.
In a vehicle sliding seat that is provided at a position where the operating lever contacts the lock lever to assemble the underframe of the seat cushion to the upper rail of the slide rail,
An actuating lever is provided that has a guide piece that abuts the receiving piece of the lock lever and swings the roller side downward against a spring at the lever end opposite to the pressing roller.

  According to a second aspect of the present invention, there is provided an actuating lever provided with an arcuate guide piece whose plate surface is curved toward the swinging direction at the lever end opposite to the pressing roller.

  In the sliding seat for a vehicle according to claim 1 of the present invention, when the under frame of the seat cushion is assembled to the upper rail of the slide rail, the operation lever is guided even if the operation lever is provided at a position where it abuts the lock lever. Since the piece comes in contact with the receiving piece of the lock lever and the operating lever moves so that the roller side swings downward against the spring, the operator holds the operation lever with his hand so that it does not hit the lock lever. There is no need to perform work, and the underframe of the seat cushion can be easily assembled to the upper rail of the slide rail to improve workability.

In the vehicular sliding seat according to the second aspect of the present invention, since it includes an operating lever provided with an arcuate guide piece whose plate surface is curved toward the swinging direction at the lever end opposite to the pressing roller, The guide piece of the actuating lever comes into contact with the receiving piece of the lock lever, and the actuating lever moves smoothly so that the roller side swings downward against the spring.

  FIG. 1 shows the same basic structure as that of a vehicular sliding seat according to a general example. In the drawing, a part of the configuration of the operating lever 1 is excluded, and other common components are denoted by the same reference numerals as those in FIGS.
