A belt-type continuously variable transmission in which a drive pulley mounted on an input shaft and a driven pulley mounted on an output shaft are connected by an endless belt, a forward- and backward-movement switchover mechanism for transmitting a driving force from an engine to the drive pulley is disposed adjacent the stationary pulley half of the drive pulley, and a starting clutch for transmitting the rotation of the output shaft to driving wheels is disposed adjacent stationary pulley half of the driven pulley. This ensures that dead spaces created in a section opposed to both the movable pulley halves which move axially can be utilized as spaces for disposition of the forward- and backward-movement switchover mechanism and the starting clutch, thereby enabling the forward- and backward-movement switchover mechanism and the starting clutch to be disposed in a compact layout.
