Abstract
Speed change gears wherein an external gear (103 in FIG. 1) is protrusively formed with a plurality of inner pins (103b) of circular cylindrical shape. The rotation of the external gear (103) corresponding to a rotational component on the axis thereof after the absorption of the rocking thereof is directly derived from a pinion gear (106). The pinion gear (106) is formed with inner pin holes (106a) into which the respectively corresponding inner pins (103b) can be loosely fitted. The power is transmitted to or from an opposite gear (27) through the pinion gear (106).
