PROBLEM TO BE SOLVED: To rouse amusement of a game by making the rotation of a windmill variable and making playing balls advance in unexpected directions and enable an integral forming by one metal mold. SOLUTION: This windmill is constituted of an axial cylinder 1 having a hole 6 into which a support shaft 5 is inserted at the inner periphery, a ball receiver 2 arranged at the outer periphery of the axial cylinder 1 to receive playing balls falling down from the upper side, a bearing 3 continuously connected to the hole of the axial cylinder 1 and arranged in front of the axial cylinder 1, and a rotary plate 4 disposed at the outer periphery of the axial cylinder 1 or in front of it. The inner peripheral face of the axial cylinder 1 is formed to have a tapered shape widening toward the rear end to impart an unexpected advancing directions to the playing balls and make it possible to integrally form it by one metal mold.
