For example, even when an impact force is generated when the reclining mechanism 20 changes the inclination angle of the body portion 14 with respect to the seat portion 16, the impact force is generated by the flap-shaped attachment 46. Be relaxed. For this reason, in such a stroller 10, it is said that the shocking force is transmitted to the body portion 14 (the back portion 40 and the pair of side portions 42), and the position of the body portion 14 is shifted or the shape is lost. Such inconvenience can be effectively prevented.
[0027]
Further, since the back portion 40 and the pair of side portions 42 are provided integrally, the back portion 40 is also supported by the back pipe 30 via the side portions 42 and the flap-shaped fittings 46, and its position and shape are reclined. It is adjusted and maintained effectively regardless of the presence or absence of.
