Abstract: A stroller includes a stroller body having a frame member and an armrest, a back part frame pivotably joined to the stroller body, and a support member connecting the armrest and the back part frame with each other. The support member has a flexibility so as to allow the back part frame to be pivoted with respect to the stroller body within a predetermined range. The support member makes it possible that the back part frame is pivoted with respect to the stroller body, in conjunction with the folding action of the stroller body.

Abstract: A stroller includes: a frame part; a handle connected to the frame part so as to be swingable; caster mechanisms turnably holding wheels; and a switching mechanism including a switching member which is configured to be held on predetermined positions in accordance with the position of the handle. The caster mechanisms are provided with locking members configured to regulate turning of the wheels. In addition, there are provided transmission mechanism configured to operate the locking members in conjunction with a movement of the switching member.

Abstract: A stroller allowing an operation for switching the conditions of the wheels in accordance with a position of the handle to be performed in a more stable and reliable manner is provided. The stroller includes a frame part; a handle swingably connected to the frame part; caster mechanisms that turnably hold wheels; and a switch mechanism having a switching member disposed on the handle. The caster mechanisms are provided with locking member for restricting turnings of the wheels. The switching member is movable about a swing center of the handle in accordance with a swinging of the handle. A transmission member operates the locking member in conjunction with an action of the switch mechanism.
