In a gear mechanism that includes a gear in which a tooth trace is twisted at a predetermined angle with respect to an axial direction, a curvature radius along a line of contact at a meshing position where a line of contact does not intersect a pitch circle is formed larger than a curvature radius along a line of contact at a meshing position where a line of contact intersects a pitch circle, on a plane of action of the gear. |
