Claims (1)

[Claims for Utility Model Registration] A pair of rear legs extending rearward and downward are rotatably connected to a pair of front legs extending forward and downward, and in the open state, each rear leg connects to each front leg. A folding mechanism of a handrail of a foldable baby stroller, which is in a state in which each rear leg is rotated in a direction away from each other and in a closed state in a state in which each rear leg is rotated in a direction in which each front leg approaches each other; The handrail is rotatably connected to each of the front legs at a position above the connecting portion of each of the front legs to the rear legs, and a retaining wall is formed at the rear end of the handrail, and a retaining wall is formed at the rear end of the handrail. A retaining protrusion is provided at the lower end of the engagement wall to be engaged with the rear leg from the rear in the open state, thereby maintaining the horizontal posture of the handrail in the open state, and maintaining the horizontal position of the handrail in the closed state. As the legs rotate, the engagement protrusion separates from the engagement wall, and the handrail is folded into a state overlapping the front leg due to gravity. A follower is formed on the handrail, whereby the handrail is rotated upward while the cam surface is in contact with the follower according to the rotation of the rear legs during the transition from the closed state to the open state, and the handrail is rotated upwardly while the cam surface contacts the follower. A folding mechanism for a handrail of a baby stroller, wherein the engaging protrusion engages the engaging wall to maintain the horizontal posture of the handrail when the handrail approaches a final position of upward rotation.
