It is about.

Background Art Conventionally, a baby carriage that rides an infant is known as a baby carriage having a baby carriage body, a seat portion and a back portion, and a seat member mounted on the baby carriage body. Most of the baby carriages currently being used are configured such that the back portion can be reclined. In many cases, the seat member is composed of a core member and a cushion member covering the core member, and the seat portion and the backrest portion of the seat member are supported by the stroller body so that the edge portion thereof can be fixed to the stroller body to be suspended. have.

In such a stroller, for example, as described in paragraphs 0053 and 0054 of JP2010-538923T, the amount of suspension from the stroller body is shortened, and the backrest part is raised by raising the back part to approach the stroller body. can do. On the contrary, it is possible to lengthen the amount of suspension from the baby carriage main body and to lie down the back portion so as to be separated from the baby carriage main body, so that the backrest portion can be laid down.

However, in the above-described conventional reclining mechanism, the length of the suspension from the stroller body of the backrest becomes long in the state where the backrest portion is inclined rearward from the stroller body, so that the backrest portion is in the width direction (lateral direction) with respect to the stroller body. It becomes easy to shake (vibration). Such shaking of the backrest worsens the ride comfort of the infant riding in the stroller, and also worsens the maneuverability of the driver (user, guardian) who drives the stroller.
