Patent ID: 8807587

Claim:
A stroller comprising: a frame part including a front leg and a rear leg, a handle connected to the frame part so as to be swingable between a first position and a second position; a caster mechanism disposed at least on one of the front leg and the rear leg, the caster mechanism including a wheel, a wheel holder configured to rotatably and turnably hold the wheel, and a locking member capable of being moved between a locking position for regulating a turning of the wheel and an unlocking position for enabling the turning of the wheel; a switching mechanism including a switching member which is configured to be held on a first holding position when the handle is located on the first position, and to be held on a second holding position when the handle is located on the second position; and a transmission mechanism disposed between the switching mechanism and the caster mechanism, and configured to transmit, to the locking member, a movement of the switching member between the first holding position and the second holding position, so as to move locking member from the unlocking position to the locking position or from the locking position to the unlocking position; wherein: the frame part further includes an armrest connected with the front leg and the rear leg, the switching member is pivotably supported in the armrest; the switching member includes a projecting part that is projectable in a trajectory zone of the handle, which is defined when the handle is swung, or a trajectory zone of a member disposed on the handle, which is defined when the handle is swung; the projecting part can project from the armrest, the switching member is structured such that, when the handle or the member disposed on the handle presses the projecting part during a movement of the handle from the first position to the second position or from the second position to the first position, the switching member is turned between the first holding position and the second holding position, when the switching member is held on the second holding position, the projecting part of the switching member is located within the trajectory zone of the handle or within the trajectory zone of the member disposed on the handle, and is pressed by the handle or the member disposed on the handle, which is swung from the second position toward the first position, and the projecting part of the switching member is pressed up to a position outside the trajectory zone of the handle or outside the trajectory zone of the member disposed on the handle, by the handle or the member disposed on the handle, which is swung from the second position toward the first position.
