Therefore, the sliding of the webbing 31 with respect to the lock mechanism 40 can be more effectively prevented. Furthermore, since the retractor 32 is disposed on the front side of the cushion frame 10F from the axis of the recliner 17, the length between the retractor 32 and the belt guiding member 33 can be shortened, and the webbing 31 The first portion 31c1 can be shortened. Accordingly, the first portion 31c1 involved in the generation of tension is shortened, and the fall of the seat back 20 toward the back side can be more effectively suppressed without being affected by the feeding length of the webbing 31. In addition, the cushion inner portion 31c11 and the back inner portion 31c13 in the first portion 31c1 of the webbing 31 are disposed so that they cannot be seen from the seated person side. As a result, the exposed portion 31c12 visible from the seated person side is shortened, and the appearance of the automobile seat 1 is improved.

  FIG. 12 shows another embodiment of the present invention. FIG. 12 is a diagram corresponding to FIG. 7 in the above-described embodiment, and the same reference numerals are given to the overlapping components, and description thereof is omitted. The difference from the above embodiment is the difference in the arrangement position of the retractor 32. In the present embodiment, the retractor 32 is mounted on the floor F on the rear side of the cushion frame 10F. Then, the webbing 31 drawn out from the retractor 32 is turned from the lower surface of the belt guiding member 33 disposed in the cushion frame 10F to the rear upper direction along the front surface and extends to the lock mechanism 40 to form the first portion 31c1. ing. Compared with the above-described embodiment, the length of the first portion 31c1 is increased by the length from the retractor 32 to the belt guiding member 33, and the effect of suppressing the falling of the seat back 20 to the back side is slightly inferior. On the other hand, it is effective when a space for arranging the retractor 32 in the seat cushion 10 cannot be found.
