  • the above-mentioned seat has a pair of side wall portions arranged on the left and right sides of the seat surface portion. Further, each side wall portion is urged by an elastic member so as to be bent inward in the left-right direction. This prevents the side walls from being folded so as to expand outward in the left and right direction as the stroller is folded (and thus from being stored with the side walls of the seat sandwiched between the stroller body (frame)). The effect of being carried out is demonstrated.
  • the above effect may be weakened (or no longer obtained) as the elastic member deteriorates over time. Furthermore, even when the stroller is in its unfolded state (that is, when an infant can ride in the stroller), the force exerted by the elastic member acts on the side wall, causing the side wall to bend slightly inward in the left-right direction. The width of the infant riding space in the left-right direction may be compressed by the above-mentioned bend. In addition, the space between the outside of the side wall in the left-right direction and the main body (frame) of the baby carriage becomes larger due to the above bending, which causes the problem that parts of the infant's body or toys are likely to get caught in the space. obtain.
