摘要

The reducer has a skidding component/carrier body (120) synchronizing with a rotation component of a planetary gear, and an internal saw tooth gear (134) formed at an opposite side of a relativity machine (150). A casing unit (136) is provided in the relativity machine, and a main bearing i.e. taper roller bearing (128), supports a carrier. The planetary gear is supported by an oily pin, and a sub bearing i.e. taper roller bearing, supports the carrier. The main bearing is arranged in radius direction outer side of the carrier than the oily pin.
