Abstract
A friction type continuously variable transmission has double cones kept in contact with an input shaft and a drive cone and is capable of transmitting the rotation of the input shaft to an output shaft so that the output shaft rotates at a higher speed than the input shaft. A mechanism is provided for preventing the double cones from rotating about the input shaft and from coming off of their support shafts. A stay is mounted on a carrier supporting the double cones. The stay carries a guide roller bearing received in a guide fixed to a housing of the transmission. The stay thus prevents the rotation of the carrier while allowing only its axial movement. A stopper surface is provided at one end of the guide to restrict the axial movement of the carrier within a predetermined range.
