Abstract
There is provided 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. A stroller 10 includes: a frame part 20; a handle 50 connected to the frame part so as to be swingable; caster mechanisms 60 and 80 configured to turnably hold wheels; and switch mechanisms 100a and 100b respectively including lock switching members capable of being pushed so as to be moved by the handle that is swung. The caster mechanisms are respectively provided with locking means capable of restricting a turning of the wheel. There are disposed transmission means 120 and 130 configured to operate the locking means in accordance with movements of the lock switching members.

A stroller comprising:
- a frame part including an armrest, a front leg, and a rear leg, the front leg and the rear leg being connected to the armrest;
- 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 means capable of moving between a locking position for restricting a turning of the wheel and an unlocking position for enabling the turning of the wheel;
- a switch mechanism supported on the armrest of the frame part and, the switch mechanism including a lock switching member capable of being pushed so as to be moved by the handle that is swung toward the first position or the second position;
- and
- a transmission means disposed between the switch mechanism and the caster mechanism and configured to transmit a moving action of the lock switching member to the locking means so as to move the locking means from the unlocking position to the locking position or from the locking position to the unlocking position, wherein:
- the caster mechanism includes a caster mechanism for front leg disposed on a lower end of the front leg, and a caster mechanism for rear leg disposed on a lower end of the rear leg;
- the switch mechanism includes a first switch mechanism to be engaged with the handle resting on the first position and a second switch mechanism to be engaged with the handle resting on the second position, the first switch mechanism and the second switch mechanism being supported on the armrest;
- and
- the transmission means includes a first transmission means disposed between the first switch mechanism and one of the caster mechanism for front leg and the caster mechanism for rear leg, and a second transmission means disposed between the second switch mechanism and the other of the caster mechanism for front leg and the caster mechanism for rear leg.
