ABSTRACT:
When a baby carriage is in its opened state, the front and rear legs extend in an inverted-V form. Each rear leg is provided with a bracket extending toward the front leg, with a foldable locking rod turnably connected at its opposite ends between the bracket and the front leg. The locking rod is adapted to be maintained in its unfolded state by being held between an attitude control surface fixedly provided on the rear leg and a slider provided on the rear leg and urged by a spring to slide toward the attitude control surface. The slider is formed with an unlocking engagement portion. When the unlocking engagement portion is slid away from the attitude control surface by operating an operating lever, the unlocking engagement portion engages the end of the locking rod to fold the locking rod.
