Abstract
PURPOSE:To enable the action of an engine brake to be promptly attained by enabling a drain release valve to discharge working oil not through a speed change control valve further a line pressure correcting valve to increase a line pressure when a select control unit is placed in an engine brake position. CONSTITUTION:A belt type continuously variable transmission 12 is equipped with a speed change control device which comprises a speed change direction selector valve unit 138 and a speed change speed selector valve unit 140 controlling working oil to be supplied to and discharged from an oil hydraulic actuator 50 for changing speed change ratio between a pair of variable pulleys 36, 38 winding 9 transmission belt 40 to be linked. Here connecting a drain release valve 186 to the oil hydraulic actuator 50, the working oil in the oil hydraulic actuator 50 can be released directly to a drain not through the speed change control device. While providing a line pressure correcting valve which increases a line pressure of oil by the predetermined value correlating to the holding pressure for a transmission belt, these release valve 186 and correcting valve are controlled to be actuated when a shift lever is controlled to an engine brake position.
