Claims

[Claims for Utility Model Registration] A mechanism for interlocking and locking left and right casters respectively attached to left and right leg members of a baby carriage, wherein each of the left and right casters is fixed to the lower end of the leg member. a rotating yoke rotatably mounted about a vertical axis relative to the fixed member; and a rotating yoke rotatable about a first horizontal axis passing through a position different from the vertical axis relative to the rotating yoke. and a wheel that can be mounted on the fixed member, the fixed member being capable of swinging about a second horizontal axis and having a position stably maintained at each end of the range of swing. A control lever is attached to the control lever, and a lock member is rotatably attached to one end of the control lever, and as the control lever swings, the lock member moves vertically along the fixed member. a guide member is provided for regulating the rotation of the baby carriage, and the rotating yoke is provided with a lock recess into which the lock member can fit when the wheel faces in the direction in which the baby carriage moves straight; and further, each of the left and right casters A locking mechanism for a caster of a baby carriage, wherein the left and right operation levers provided in connection with the stroller are connected by an interlocking rod so as to swing together.
