PROBLEM TO BE SOLVED: To provide a folding buggy having a folding interlock mechanism easy in quality control, strength management, assembling work, and maintenance. SOLUTION: The folding buggy is equipped with rear legs 5 and a a rear leg coupling member 50 capable of being folded. The rear leg coupling member 50 includes rotation parts 52b held by the rear legs 5 in such a way as rotating round an axis positioned not overlapping on the rear legs 5 and bent parts 51 and 52a to couple the rotation parts 52b in pair and bending in association with rotations of the rotation parts 52b. The buggy includes moving members 31 and 70 moving in the longitudinal direction of the rear legs 5 in association with the folding motion of the buggy and a movement changing means to couple the moving members 31 and 70 and the rotation parts 52b so as to convert the motion in the vertical direction of the moving members 31 and 70 into the rotational motion of the rotation parts 52b. The movement changing means includes a combination of a guide groove 71 extending spirally with a guide pin positioned inside the guide groove 71 and capable of moving spirally along the groove 71.
