Claims

[Claims for Utility Model Registration] In a gear bearing structure in which an inner race is inserted between a bearing that rotatably supports a gear on a rotating shaft and the rotating shaft, at least one end face of the inner race is rotated. A tapered surface forming a predetermined angle with respect to a plane perpendicular to the axis, and an end surface of a member that is adjacent to the inner race and rotates integrally with the rotating shaft, on the side opposite to the tapered surface, is the tapered surface. A bearing structure for a gear, characterized in that the tapered surface forms a predetermined angle with respect to a plane orthogonal to the rotational axis so as to be complementary to the rotational axis.
