Abstract: A stroller capable of reducing dimensions upon folded, while maintaining a rigidity is proposed. A stroller includes: a core member; a front leg that is swingably connected to the core member and extends downward from the core member toward the front; and a pair of rear legs that are swingably connected to the core member and extend downward from the core member toward the rear. The pair of rear legs are arranged in a vehicle width direction, and are, in the used condition, separated away from each other, as a certain point on each rear leg separates away from the core member. An end of the front leg on the opposite side to the core member and ends of the rear legs on the opposite side to the core member are located on positions closer to each other in a folded condition than in a used condition.

Abstract: There is provided a child car seat capable of preventing a seat body from being unintentionally moved to a turning position. The child car seat includes a pedestal and a seat body that can be slid with respect to the pedestal. A plurality of reclining positions and a turning position are included in a range within which the seat body can be slid. The seat body includes a retractable projecting member projecting toward the pedestal, and an operation member connected to the projecting member. The seat body can be held in the respective positions when the projecting member is engaged with the pedestal. An operation amount of the operation member, which is required for sliding the seat body between the reclining positions, is smaller than an operation amount of the operation member, which is required for sliding the seat body from the reclining position to the turning position.
