された、乳母車の開状態ロック機構。(1) A folding baby carriage that includes a pair of front legs, a pair of rear legs, a pair of push bars, and a pair of connecting bars that rotatably connect each rear leg and each push bar at both ends. When each of the push rods and the corresponding connecting rods are fixed in a straight line, the open state of the baby carriage is locked, and each of the push rods and the corresponding connecting rods are in a bent state. In such a mechanism for locking the open state of the baby carriage, in which the closed state of the baby carriage is obtained with a movement of the baby carriage, each of the rear legs and each of the push rods are provided at both ends of each of the connecting rods, respectively. first and second pivot points rotatably connecting the push rods are located, and the second pivot point connecting each of the push rods is located a predetermined distance above the lower end of each push rod, thereby In the straight line state, each of the push rods and the connecting rod overlap each other by the predetermined distance, and a lock operation member is provided at the lower end of each of the push rods so as to be slidable in the length direction of the push rod. Each of these lock operation members is always urged by a spring to slide toward the lower end of each push rod, and at the lower end of each lock operation member, a retaining part is connected to an inclined guide part. each of the connecting rods is formed with a hook-shaped portion that engages with the engaging portion when the lock operation member is at the lower end position, and each of the connecting rods is formed with a hook-shaped portion following the inclined guide portion; The lock operating member slides on the push rod toward the upper end of the push rod against the elasticity of the spring, and the hook-shaped portion of the engaging part is formed on the opposing surfaces of the connecting rod and each lock operating member. a baby carriage, wherein a pair of an engaging pawl and an engaging hole are formed that engage with each other in order to fix the slide of each of the locking operation members to each of the connecting rods when the locking member is disengaged from the locking member; Open state locking mechanism.
