Abstract
A forward-reverse rotation device for a continuously variable transmission is provided to reduce the manufacturing cost of a forward-reverse rotation device for a continuously variable transmission. A forward-reverse rotation device for a continuously variable transmission is equipped with a planetary gear set , a reverse brake , and a forward clutch . The planetary gear set has a sun gear provided on an input shaft , a ring gear , double planetary gears , and a carrier that axially supports the double planetary gears and serves to output power to output shaft . The brake is for allowing and prohibiting the rotation of the ring gear . The clutch is a mechanism for coupling and releasing the input shaft to and from the carrier . The sun gear and splines are formed integrally on an external circumferential surface of the input shaft . The clutch has a clutch drum that has internal splines that are press-formed integrally into the clutch drum and mesh with the splines
