To play a game such as baseball by using a doll by arranging a transmission mechanism operated by an operation part and operated by returning to a former position by an energizing means in the doll having a movable part y swingingly arranging an arm part and performing a desired game.

By pressing a pushing-down button 12 downward against an energizing spring 13 in a state of placing a ball on a hand part 7 of a movable arm part 5, a rack bar 11 is moved downward. Then, a pinion gear 21, in its turn, a first clutch plate 22 meshing with a rack tooth 15 of a rack member 14 is rotatably driven according to a movement of the rack bar 11. At this time, since clutch teeth 24 and 24 of the first clutch plates 22 and 23 mesh with each other by a clutch spring 25, both clutch plates 22 and 23 are integrally rotated, and an arm support shaft 16 is rotated, so that a movable arm part 5 connected to this shaft is rotated by a prescribed angle to thereby perform ball throwing operation of a ball placed on the hand part 7.
