摘要 In a control apparatus for an automotive continuously variable transmission (2) having a forward-reverse selector mechanism (7) in which a gear ratio for reverse is set closer to a speed reducing side than a gear ratio for forward and a belt type continuously variable transmission mechanism (6), a PH pressure that is outputted from a first regulator valve (11) and a PL pressure that is outputted from a second regulator valve (12) are changeably supplied to one and the other of a hydraulic cylinder (60b) of a drive pulley (60) and a hydraulic cylinder (61b) of a driven pulley (60) via a shift control valve (13). A hydraulic pressure supplied to a reversing hydraulic pressure connecting element (75) from a reversing manual valve (20) is inputted into an oil chamber (110a) of a first regulator valve (11) so that the PH pressure is increased with the hydraulic pressure so inputted. <IMAGE>
