b shows an example provided on the pedestal 3, and the goniometer 8c shows an example provided on the upper surface of the side 1d of the seat body. However, the mounting position of any of these goniometers is difficult to see when the child seat is fixed on the vehicle seat.

On the other hand, JI established by the Japan Standards Association
According to SD0401-1996 Automobile Supplies-Child Protection System (hereinafter abbreviated as JIS standard), the types and categories of child protection systems are regulated.
It is divided into "baby beds", "infant seats", and "school child seats". Further, the categories are W1 (less than 10 kg), W2 (less than 10 kg), depending on the weight range of young people (general term for newborns, babies, infants, school children, etc. weighing 36 kg or less).
(9 kg to 18 kg), W3 (15 kg to 25 kg)
kg or less) and W4 (22 kg or more and 36 kg or less). FIG. 9 shows a rear-facing exclusive infant seat corresponding to the section W1. In the figure, C is a rear-facing infant seat W1. There are two types of child seats C corresponding to the JIS standard category W1. One type has an arc-shaped bottom surface, and can be used as a rocking chair indoors, and the other type. The bottom has a flat surface, and it is a type that can be stably seated.

FIGS. 9 (a) and 9 (b) are side views showing the rearward-facing infant seat (W1) C mounted on an automobile seat. FIG. 9A shows an example in which the bottom surface 1e of the child seat main body 1 has an arc shape. Since the bottom surface 1e has an arc shape as described above, the mounting angle of the child seat main body 1 with respect to the seat S of the automobile is arbitrary. It can be attached and fixed with a seat belt. Therefore, it is possible that the mounting state is nearly horizontal like the child seat C1 indicated by the two-dot chain line, but such a nearly horizontal mounting state is not an appropriate mounting angle. In the child seat C1 having the bottom surface 1e having an arc shape as described above, the child seat C1 can be freely mounted at an arbitrary angle.

On the other hand, FIG. 9B shows an example in which the bottom surface 1e of the child seat body 1 is a flat surface. In this case, since the bottom surface 1f of the child seat body 1 is flat and the seat surface S1 of the car seat S is also flat,
Unlike FIG. 9A, the angle of attachment to the vehicle is uniquely determined. However, since the seating surface S1 of the vehicle seat S has various angles depending on the vehicle as described above, there may be a case where the seating surface S2 is almost horizontal as shown by a two-dot chain line in FIG. Then child seat C
Also, the mounting angle becomes improper, such as the position of C2 which is nearly horizontal as indicated by the two-dot chain line. As described above, even when the bottom surface 1f of the child seat body 1 is a flat surface, it is necessary to check each time whether the mounting angle is appropriate. As described above, it is necessary to confirm whether the mounting angle is appropriate for each of the two types of the child seat C dedicated to the rearward direction. In the conventional child seat C, the same as the child seat B in FIG. In many cases, the goniometer is in a position where it is difficult to see when placing the child seat, so that the child often forgets to visually recognize the goniometer when placing the child seat on the car seat.
