Abstract
A continuously variable transmission of an automotive vehicle has a start assist device, a forward-reverse changeover device, and a V-belt type transmission. The changeover device has an input shaft for receiving power from the start assist device. The V-belt type transmission has a drive shaft connected to a drive pulley. The input shaft and the drive shaft are aligned along a common longitudinal central axis. A fluid passage arrangement for the transmission includes a hydraulic fluid passage for a chamber of the drive pulley, which passage includes mutually communicating axial holes formed in the input shaft and the drive shaft. One of the axial holes communicates with a hydraulic fluid supply, while the other axial hole communicates with the chamber. The fluid passage arrangement further has lubricating fluid passages for the transmission and the changeover device. These lubricating fluid passages are formed in radially outer peripheral portions with respect to the input shaft and extend axially along the input shaft.
