PURPOSE:To certainly prevent the shortage of lubricating oil by feeding lubricating oil into a chamber formed between the sun gear and the carrier cylindrical part of a planetary gear apparatus from a lubricating-oil feeding apparatus and feeding the lubricating oil onto a pinion and a carrier by a centrifugal force. CONSTITUTION:A transmission is equipped with a planetary gear apparatus consisting of a sun gear S integrally formed with a sun gear shaft 29 rotatably fitted onto an output shaft 12, pinion P meshed with the sun gear S, carrier PC which supports the pinion P and has a cylindrical part 2 spline-fitted onto the outer periphery of the output shaft 12, and a ring gear R. In this case, a chamber B formed with the outer periphery of the output shaft 12, rear edge surface of a carrier cylindrical part 2, and the inner periphery of the sun gear shaft 29 is formed. Lubricating oil is supplied into the chamber B from a lubricating-oil feeding means 4, and the lubricating oil in the chamber B is supplied onto the pinion P and the carrier PC by a centrifugal force through a lubricating-oil passage 5 formed onto the sun gear S. |
