To provide a stroller in which a wheel state-changing operation can be stably and surely performed according to the position of the handle. The stroller comprises a frame part, a handle (50) so connected to the frame part as to be capable of swinging, caster mechanisms rotatably holding wheels, and switch mechanisms (100a, 100b) each having a lock-changing member (110) movable when pressed by the swinging handle (50). Each of the caster mechanisms has a lock means for restricting the rotation of each wheel. The stroller further includes transmission means (120, 130) for operating the lock means in linkage with movement of respective lock-changing members.
