Abstract

By attaining a certain correlation between shifting the weight of a toy main body and shifting the center of gravity the toy main body between legs thereof there is provided a biped toy that can walk on two feet as naturally as a human being walks without falling down. Left and right legs can be forwarded as naturally as the human being does by positioning the center of gravity above one of the legs which supports the toy main body. With a view to eliminating unstable actions of leg portions, fulcrums thereof are positioned rearward, with a view to eliminating unstable actions of a torso, a fulcrum thereof is positioned rearward, and with a view to eliminating unstable actions of the toy main body, fulcrums of the left and right foot portions are each positioned either inwardly or outwardly.

[0005] In order to allow a biped toy to walk as naturally as a human being does there is a certain correlation to be attained between shifting the weight of a toy main body and shifting the center of gravity thereof between the legs thereof.

[0006] With the prior art, however, since the aforesaid technique of shifting the weight and center of gravity has not been materialized, if the natural walk is tried to be realized by lifting up the left and right legs of a biped toy alternately, the toy falls down, and ther...
