Provided is a continuously variable transmission including: a first pulley including a first fixed sheave fixed to a first rotating shaft and a first movable sheave rotating integrally with the first rotating shaft and is movable along the first rotating shaft; a second pulley including a second fixed sheave fixed to a second rotating shaft and a second movable sheave rotating integrally with the second rotating shaft and is movable along the second rotating shaft; and a transmission belt wrapped around a belt wrapping groove formed on the first pulley and around a belt wrapping groove formed on the second pulley. In a belt track for a minimum gear ratio, surfaces of the first pulley that are in contact with the transmission belt have a lower coefficient of friction relative to the transmission belt than surfaces of the second pulley that are in contact with the transmission belt.

A transverse member (1) for a drive belt for a continuously variable transmission with a base part (10) and two pillar parts (11). On either side thereof, the transverse member is provided with a pulley contact surface (12) for contacting pulleys of the transmission. The pulley contact surfaces (12) are each provided in two sections (13, 14) with a surface part (15) of the transverse member (1) provided there between that does not arrive in contact with the transmission pulleys, whereof a first section (13) is provided at least partly in the base part (10) and whereof a second section (14) is wholly provided in a respective pillar part (11).
