ABSTRACT:
In a gear mechanism, inner gear teeth and outer gear teeth are formed of high-tooth. An engagement ratio of the inner and outer gear teeth is configured so as to be 2.0 or more, whereby a load can be transferred between the inner and outer teeth via a continuous gear engagement of at least two pairs of gear teeth thereof. Accordingly, a contact face pressure and a bending stress occurring to inner and outer gear teeth can be reduced, the limitation of the durability of the gear mechanism due to the large difference of durability between the inner and outer gear teeth can be improved, and the necessity of increasing hardness of the inner gear teeth can be lessened.
