Abstract
A hydraulic type pressing device secures the contact pressure between the peripheral surfaces of respective power rollers and the inner surfaces of respective input side disks and respective output side disks. When a torque to be transmitted changes abruptly, the pressing force of the pressing device is set to a value corresponding to the maximum torque to be transmitted by a toroidal type continuously variable transmission. According to this configuration, the variation of the transmission ratio based on the variation of the elastic deformation values at the respective portions is suppressed to prevent the uncomfortable feeling of a driver.
