PROBLEM TO BE SOLVED: To reduce load on the shaft to make the shaft hard to be broken and to make the rotation of the windmill usually in a prescribed direction to improve a player interest by equipping a rotation direction regrating means inside a bearing means attached on the rotation shaft of the windmill. ;SOLUTION: A bearing means 20 with a rotation direction regulating means to regulate the rotation direction in one way is intercalated to pivotally support a rotation shaft 2 of a rotation body 1 of this windmill rotatable only in a predetermined direction onto a bearing body 11 made of synthetic resin to be equipped on a game board 10. The rotation body 1 has protruding parts 3 to rotate the rotation body 1 and to bounce balls when launched balls hit the windmill on several parts in the radial positions on the periphery face, dent parts 5 to fit the head part 4 of the rotation shaft 2 in the front center and a cylindrical parts 7 with a through hole 6 to insert the rotation shaft on the back side of the dents 5 are integrally formed. The windmill is formed so that an engaging groove 8 can be fit into either of the dent parts 5 of the rotation body 1 or the head part 4 of the rotation shaft 2 and an engaging protruding bar 9 to another.;COPYRIGHT: (C)1999,JPO
