摘要：
A plurality of microscopic grooves are created on the surface of the teeth of planetary gears, and thus, irregular unevenness is created. This irregular unevenness includes a plurality of first microscopic grooves which function as lubricant grooves and a plurality of second microscopic grooves which are shallower than the first microscopic grooves.
