ABSTRACT:
A lubrication device for a toroidal type continuously variable transmission, which can set the speed change ratio continuously by transmitting a torque inputted from a power source by rolling members contacting each other through an oil film, and by varying the position of the contact portion of those rolling members steplessly, characterized by comprising: an auxiliary hydraulic power unit for generating an oil pressure without relying on said power source, a preliminary operation detector for detecting whether or not the preliminary operation relative to the start up of said power source is executed, and a preliminary lubricating mechanism for feeding the lubricating oil to the contact portion between said rolling members by means of said auxiliary hydraulic power unit before starting up said power source, when the preliminary operation is detected.
