ABSTRACT:
A power transmission mechanism includes a gear member and an annular and eccentric floating member having internal gear teeth meshed with external gear teeth of the gear member. A pair of guide plates provided on both outer sides of either the gear member or floating member prevent lateral disengagement of the floating member from the gear member. A pair of seal rings arranged between the inner sides of the guide plates and the outer sides of either the floating member or gear member prevent entry of dust or the like foreign material into a substantially closed space between the teeth of the gear member and the floating member, to thereby improve the durability of the mechanism.
