<p>A locking mechanism for a push rod of a baby carriage is constructed to fix a push rod (12) in its face-to-back push state and face-to-face push state and comprises a hook (15) having an engaging recess adapted to fit on engaging pins erected on the baby carriage, and a knob (16) operable to rotate the hook (15). The knob (16) is slidable and is constantly urged by a spring (36a) toward the hook (15). The knob (16) has an engaging projection (31), while the hook (15) has an engaging recess (32) engageable with the engaging projection (31). When the engaging projection (31) and the engaging recess (32) are engaged with each other and when the rotation of the hook (15) is not inhibited, the rotation of the knob (16) causes the rotation of the hook (15). On the other hand, when the rotation of the hook (15) is inhibited by an engaging pin, the rotation of the knob (16) causes the knob (16) to slide away from the hook (15) against the force of the spring (36a), thereby canceling the engagement between the engaging projection (31) and the engaging recess (32).</p> |
