[ Further, the lid member 89 can hide the reinforcing ribs 35 and improve the appearance. Further, when the lid member 89 is made of a relatively high-strength material such as resin, the rigidity of the child sheet body 20 can be further increased. On the other hand, when the lid member 89 is formed of a relatively soft material such as foamed styrol or rubber, the whole or a part of the lid member 89 forming the surface of the lid member 89 is extremely hardened by the storage cavity 27 Can be effectively prevented. Particularly, in the case where the reinforcing rib 35 is provided in the short neck portion 37b and the lid member 89 is formed by using a relatively soft material, it is possible to improve both the rigidity and the ride comfort.

In the present embodiment, the accommodating cavity 27 includes the end surface of the belt supporting member 34 as a part of the cavity bottom surface 28. More specifically, the belt supporting member 34 is formed in a cylindrical shape. The second belt member 92 is extended from one opening of the cylindrical belt supporting member 34. One end surface (a top surface) of the tubular belt supporting member 34 forms a part of the cavity bottom surface 28. According to this embodiment, the second belt member 92 The supporting state can be stabilized.

Each of the bottom end portions 37b of the seat portion 45 and the backrest portion 50 is formed to be in conformity with the connecting position of the side portion 55 and the seating portion 45 and the backrest portion 50, As shown in Fig. According to this embodiment, the strength of the side portion 55 is secured to maintain the rigidity of the child seat 10, and the second belt member 92 at the time of non-use can be folded to be formed in the storage cavity 27 .

<Modifications>

It is also possible to make various modifications to the above-described embodiments. Hereinafter, an example of the modification will be described.

The claw piece 85 of the lock-off device 80 has the base extension 85a extending from the flange 84 in the width direction and the base extension 85a extending upward from the base extension 85a And an end claw portion 85b which is extended and extended. However, the present invention is not limited to this. For example, the claw piece 85 may be provided on the device main body 81 and have a tip end claw portion extending forward or rearward. The lock device 80 can be positioned with respect to the seat body portion 30 by allowing the device main body portion 81 to slide in the groove 33. [ Therefore, it is possible to easily mount the lock-off device 80 to the seat body portion 30. [

Unlike the above-described embodiment, the fastening hole 87 is formed by engaging the reinforcing arm portion 65 with the rear portion of the lock-off device 80 that is located rearward beyond the slit 80a . In this example, the claw piece 85 may be provided at a position which is located forward of the slit 80a of the lock-off device 80. [ In this modified example as well, a portion of the lock-off device 80, which is one side of the slit 80a in the front-rear direction, can be fixed to the seat body 30 by the fastening member 87, The other part of the slit 80a in the front and rear direction of the lock-off device 80 is engaged with the claw piece 85 and the flange part 84 and the three- (30). &Lt; / RTI &gt; That is, the lock-off device 80 can be connected to the seat main body 30 on both sides of the slit 80a opened downward. Thus, the lock-off device 80 can be more reliably fixed to the seat body portion 30. [ In addition, deformation of the lock-off device 80 can be prevented, and the lock-off device 80 can be stabilized and the seat belt 7 can be gripped.
