PURPOSE:To make the oil level of a planetary gear mechanism constant so as to maintain stable lubrication performance in a transmission whose planetary gear mechanisms is connected to the input part of a frictional type continuously variable transmission as an accelerator. CONSTITUTION:Lubrication oil supply holes 31, 32 are provided on housings 11, 12 of a transmission mechanism 1 and a planetary gear mechanism 2 respectively, and the lubrication oil is circularly supplied from an oil tank 33. A communication hole 36 is formed on the lower part of side surfaces of respective housings 11, 21, and then the oil levels in both housings 11, 12 are made constant.
