PURPOSE: To enable a toy to walk stably even with small feet by supporting the toy on three points of the rear lower end of the trunk with the head and two legs.
CONSTITUTION: A toy A is supported on three points of the rear lower end of a trunk 1 and both legs 4. A motor 5 is rotated by turning on a switch 35 to rotate a drive gear 7 to a slide gear 8b. A turning force is transmitted to a leg driving gear 11 through a first intermediate gear 9a and a second intermediate gear 10a to rotate a support shaft 21. Both legs 4 move alternately to perform a walking action. As one leg 4 ascends, the other leg descends to disturb balance. However, since the whole toy is supported on three points, it walks without falling down. When the walking action continues, the slide gear 8b slides so that the turning force of the motor 5 is transmitted to an arm driving gear 9b and mouth driving gear 10b. A connecting link 22 and connecting rod 26 move vertically so that the mouth 2 moves vertically and the arms 3 are swung vertically.
