The front operation lever (7) is mainly used to adjust the tilt angle of the seat back (SB), and the rear operation lever (7) is used to tilt the seat back (SB) forward and the seat cushion (SC) vehicle floor. The lock on the side is released so that the seat cushion (SC) can be lifted up.
[0014]
As shown in FIG. 2, the finisher cover (A) has a resin main body (1) having a certain rigidity, and a notch (12) formed by notching a part of the flange (11) of the main body (1). And a cover piece (2) having flexibility fixed to.
[0015]
A storage recess (1A) that houses the front operation lever (7) is provided on the front side of the main body (1), and the front operation lever (7) is inserted into one side wall facing the storage recess (1A). The front through hole (10) is opened.
[0016]
The cover piece (2) is fixed by thermal caulking (23) (23) along a notch (12) formed by notching the flange (11) on the rear side from the top of the main body (1). .
[0017]
A movable notch (21) of the arm (4) fastened to the seat back (SB) is cut out at the top of the cover piece (2), and the rear part is long in the vertical direction through which the rear operation lever (6) is inserted. The rear through hole (20) is opened.
[0018]
The rear through hole (20) is formed by a tongue-shaped closing piece (22) extending on the cover piece (2) and the cover piece (2), and the rear through hole (20) is formed on the closing piece (22). By opening, the opened rear operation lever (6) is formed so as to be able to enter the rear through hole (20) inward from the direction of the outer edge (24) of the cover piece (2).
[0019]
The closing piece (22) is sized to close the gap between the movable arm (4) and the rear operation lever (6), and its inner end edge (25) becomes a hole edge of the rear through hole (20). Part of the outer edge (24) forms the mouth edge of the notch (21).
[0020]
Accordingly, as shown in the chain line in FIG. 2, the closing piece (22) is connected to the cover piece (2) only at the upper end side of the rear passage hole (20), so when the upper end is bent, the rear passage hole ( 20) has a large cutout shape communicating with the outside, and the rear operation lever (6) can be inserted into the rear through hole (20) from the mounting direction of the finisher cover (A).
