To provide a device for controlling a lubricating oil passage of a belt type continuously variable transmission for a vehicle capable of achieving effective lubrication.
This device for controlling the lubricating oil passage supplies lubricating oil discharged from a drain oil passage to an input side variable pulley 42 and/or an output side variable pulley 46 not through an oil cooler 124 when lubricating temperature is equal to or lower than previously fixed specified temperature. Consequently, efficient lubrication is achieved at the time of low oil temperature in starting a vehicle, etc. by supplying the lubricating oil of comparatively high temperature discharged from the drain oil passage not through the oil cooler 124 for lubrication of pulley bearing parts 134, 136 especially easy to cause loss when lubricating oil temperature is comparatively low.
