At least one supporting disk is provided on which the intermediate gear is axially supported, and a duct, that is connectable to the lubricant circuit of the internal combustion engine, to supply lubricant to the needle bearing. The support disk and the axle contact one another at the end faces, the mouth of the lubricant duct that opens toward the needle bearing is formed by one or more recesses on the contact surface of the support disk and/or on the contact surface of the axle.
