Stroller

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 the locking member from the unlocking position to the locking position or from the locking position to the unlocking position;
• wherein:
• the switching member is slidably disposed on the handle;
• and
• the switching member is arranged on the first holding position on the handle when the handle is located on the first position, and is arranged on the second holding position on the handle, which is different from the first holding position, when the handle is located on the second position.

• wherein:
• the switching member is pivotably supported on the frame part;
• 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;
• and
• 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.
