Abstract
An oil sump 44 and a second oil supply passage 45, which are to lead lubrication oil from a first oil supply passage 43 to where lubrication is needed, i.e., to gears and a clutch, are formed in a sun gear 21, which has a sufficient strength as a torque transmission member. In comparison with another case where an oil sump and an oil supply passage are provided in a relatively thin member such as a sleeve 3, the unfavorable effect of stress concentration around the oiling aperture and of deterioration of strength from the reduced thickness can be greatly minimized. In addition, the fabrication of the oil sump and the oil supply passage is much easier and cost-effective than if they were to be provided in a thinner member.
