In a belt type continuously variable transmission, the oil for the canceler oil chamber and the oil for lubricating the endless belt are commonly used to reduce the required amount of oil to be supplied. The gear shift control oil is supplied to the pulley oil chamber of the driven pulley mounted on the output shaft of the belt type continuously variable transmission through a feed pipe, oil holes of a plug, an oil groove, oil holes of the output shaft and oil holes of the movable pulley half. The lubricating oil supplied to a first in-shaft oil chamber of the output shaft is further supplied through the oil holes of the output shaft to the canceler oil chamber of the driven pulley and also from the first in-shaft oil chamber through a throttle in the plug, the second in-shaft oil chamber and the oil holes of the output shaft to the endless belt.
