According to this embodiment, each storage cavity 27 capable of receiving the second belt member 92 includes, as a part of the cavity bottom surface 28, a position at which the corresponding second belt member 92 extends and protrudes. Thus, it is formed in the seat portion 40 . Therefore, the 2nd belt member 92 at the time of non-use can be folded, and it can form in the storage cavity 27 favorably. In addition, corresponding to the extended protrusion position of the 2nd belt member 92, the two storage cavities 27 are spaced apart in the width direction, and are provided. Each of the storage cavities 27 is located at both ends in the width direction in the waist region 37 including the connection positions of the seat portion 45 in the seat portion 40 and the backrest portion 50 . Accordingly, the storage cavity 27 is disposed outward in the width direction and rearward in the front-back direction from the site where the child will mainly apply its own weight through the cover material 99 of the child seat 10 . has been For this reason, this storage cavity 27 does not deteriorate the comfort of the child seat 10. As described above, according to the present embodiment, it is possible to store the child's belt when not in use nicely without relying on a deep recess over a large area. In addition, the tongue 94 through which the 2nd belt member 92 has passed may be accommodated in the storage cavity 27, and may be accommodated in the storage recessed part 25 mentioned above.

In particular, in this embodiment, the child seat main body 20 has a pair of cover members 89 attached on the seat main body part 30 . On the other hand, as shown in FIGS. 15 and 16 , in the seat body portion 30 , an end concave portion 37b is formed in each end region 37a of the waist region 37 . And each cover member 89 is arrange|positioned so that the short recessed part 37b of the corresponding side may be covered. As shown in FIG. 15 , the seat body 30 has a pair of belt support members 34 that support each second belt member 92 . Each belt support member 34 is arrange|positioned in the short recessed part 37b of the corresponding side. Moreover, the reinforcing rib 35 is provided in each end recessed part 37b. At least one reinforcing rib 35 is connected to the belt support member 34 in each end recessed portion 37b. Each cover member 89 covers the short recessed portion 37b around the corresponding belt support member 34 . And each lid member 89 forms the storage cavity 27 which can accommodate the 2nd belt member 92 in the part in which each belt support member 34 is located.

According to this embodiment, the rigidity of the child seat main body 20 can be reinforced by the reinforcing rib 35. As shown in FIG. Further, by the cover member 89, the appearance can be improved by hiding the reinforcing ribs 35. Moreover, when the cover member 89 consists of comparatively high strength material, such as resin, the rigidity of the child seat main body 20 can be reinforced further. On the other hand, when the cover member 89 is made of a relatively soft material such as foamed Styrol or rubber for the entirety or a part constituting the surface thereof, it is extremely unlikely that the riding comfort is deteriorated due to the storage cavity 27 . can be effectively prevented. In particular, when the reinforcing rib 35 is provided in the concave portion 37b and the lid member 89 is formed using a relatively soft material, both the improvement of rigidity and the improvement of riding comfort can be achieved.

Moreover, in this embodiment, the storage cavity 27 contains the end surface of the belt support member 34 as a part of the cavity bottom surface 28. As shown in FIG. More specifically, the belt support member 34 is formed in a cylindrical shape. The second belt member 92 extends and protrudes from one opening of the cylindrical belt support member 34 . And one end surface (front surface) of the cylindrical belt support member 34 forms a part of the cavity bottom surface 28. According to this embodiment, the 2nd belt member 92 support can be stabilized.

Further, according to the present embodiment, each of the lower concave portions 37b conforms to the connection position of the side portion 55 , the seat portion 45 , and the backrest portion 50 , and the seat portion 45 and the backrest portion 50 . ) is formed on the surface of According to this embodiment, while securing the strength of the side portion 55 and maintaining the rigidity of the child seat 10, the second belt member 92 when not in use can be folded to be nicely formed in the storage cavity 27. can

<Modified example>

Moreover, it is possible to add various changes with respect to the above-mentioned embodiment. Hereinafter, an example of a deformation|transformation is demonstrated.

In the above-described embodiment, the claw piece 85 of the lock-off device 80 extends upwardly from the base end extension 85a and the base end extension 85a extending and protruding from the flange portion 84 in the width direction. Although the example with the tip claw part 85b extended and raised was shown, it is not limited to this. For example, the claw piece 85 may be provided on the device main body 81 and may have a tip claw portion extending forward or rearward. Also in this example, the lock-off device 80 can be positioned with respect to the seat body 30 by allowing the device body 81 to slide in the groove 33 . Accordingly, it becomes possible to easily attach the lock-off device 80 to the seat body portion 30 .

Moreover, unlike the above-described embodiment, the fastener 87 penetrates the reinforcing arm portion 65 from the rear side to the front side, and engages with a portion rearward than the slit 80a of the lock-off device 80 . You can also let it go. In this example, the claw piece 85 may be provided in the part used as front rather than the slit 80a of the lock-off device 80. As shown in FIG. Also in such a modified example, the part which becomes one side of the slit 80a in the front-back direction in the lock-off device 80 can be fixed to the seat body part 30 by the fastener 87, A portion of the lock-off device 80 on the other side of the slit 80a in the front-rear direction is engaged with the claw piece 85 and the flange portion 84 and the triangular frame 32 to form the seat body. The position may be determined in the unit 30 . That is, the lock-off device 80 can be connected to the seat body part 30 on both sides of the slit 80a opened downward. Thereby, the lock-off device 80 can be fixed to the seat body part 30 more reliably. In addition, by preventing deformation of the lock-off device 80 , the lock-off device 80 is stabilized and it becomes possible to grip the seat belt 7 .
