Inner tangentially driving wheel

Abstract

An inner tangentially driving wheel providing a driving apparatus at the position on a tangent line of the inner circle of the wheel to lower a position of a force exertion point mainly includes a driving apparatus disposed at the position of an inner circle tangent point at the lower aspect of the inner circle of the wheel. The driving apparatus is supported by a railing device respectively disposed on bisecting angles at the upper aspect thereof to efficiently and tangentially move a motion wheel which moves oppositely; through the operation of an external force, it drives the motion wheel in an inner tangentially driving type thereby defining an hollow state on the inner arcuate plane of the wheel so as to lower the position of the force exertion point for operation and provide extensive applications for various kinds of exerciser or toys.
