A handle 16 (FIG. 1) of a reclining mechanism is provided on the side of the cushion portion 2, and is provided transversely to a rear portion of a substantially U-shaped leg member 17 having one end connected thereto. The cross portion 18 can be selectively engaged with one of the rack grooves 19 provided on the back surface of the shell 3.

As shown in FIG. 1 and FIG.
On both sides of the rear part, the belt through holes 2
The tang belt 24 is engaged with the lock 25 by passing the lap belt 22 and the shoulder belt 23 constituting the vehicle seat belt 21 (FIG. 1) from one side to the other side in the left-right direction. By doing so, the entire child seat can be fixed on the automobile seat S.
