A control device for a belt-type continuously variable transmission, the control device comprising: a drive source; a belt-type continuously-variable transmitting mechanism including a primary pulley, a secondary pulley, and a belt wound on sheave surfaces (42c, 42d, 43c, 43d) of both the primary and secondary pulleys (42, 43) and formed by stacking multiple elements in an annular shape; a forward/reverse switching mechanism provided between the drive source and the belt-type continuously-variable transmitting mechanism, configured to switch a transmission-input rotational direction by engaging a forward-side friction engagement element when a range position is a forward running range and by engaging a reverse-side friction engagement element when the range position is a reverse running range, and configured to release both of the forward-side and reverse-side friction engagement elements (31, 32) when the range position is a non-running range; and a hydraulic control circuit configured to control pulley hydraulic pressures for the primary pulley and the secondary pulley and engagement-element pressures for the forward-side friction engagement element and the reverse-side friction engagement element, characterized by a selection control means (8, FIG. 4) for controlling the hydraulic control circuit to cause the pulley hydraulic pressure to be equal to an idle-time clamping pressure which is higher than an idle-time minimum pressure calculated from an input torque, when the drive source is in operation during a selection of the non-running range, wherein the selection control means (8, FIG. 4) sets the idle-time clamping pressure such that a belt clamping force which maintains the elements of the belt on the sheave surfaces (42c, 42d, 43c, 43d) is larger than a drag torque which is generated in the forward/reverse switching mechanism. a drive source; a belt-type continuously-variable transmitting mechanism including a primary pulley, a secondary pulley, and a belt wound on sheave surfaces (42c, 42d, 43c, 43d) of both the primary and secondary pulleys (42, 43) and formed by stacking multiple elements in an annular shape; a primary pulley, a secondary pulley, and a belt wound on sheave surfaces (42c, 42d, 43c, 43d) of both the primary and secondary pulleys (42, 43) and formed by stacking multiple elements in an annular shape; a forward/reverse switching mechanism provided between the drive source and the belt-type continuously-variable transmitting mechanism, configured to switch a transmission-input rotational direction by engaging a forward-side friction engagement element when a range position is a forward running range and by engaging a reverse-side friction engagement element when the range position is a reverse running range, and configured to release both of the forward-side and reverse-side friction engagement elements (31, 32) when the range position is a non-running range; and provided between the drive source and the belt-type continuously-variable transmitting mechanism, configured to switch a transmission-input rotational direction by engaging a forward-side friction engagement element when a range position is a forward running range and by engaging a reverse-side friction engagement element when the range position is a reverse running range, and configured to release both of the forward-side and reverse-side friction engagement elements (31, 32) when the range position is a non-running range; and a hydraulic control circuit configured to control pulley hydraulic pressures for the primary pulley and the secondary pulley and engagement-element pressures for the forward-side friction engagement element and the reverse-side friction engagement element, characterized by a selection control means (8, FIG. 4) for controlling the hydraulic control circuit to cause the pulley hydraulic pressure to be equal to an idle-time clamping pressure which is higher than an idle-time minimum pressure calculated from an input torque, when the drive source is in operation during a selection of the non-running range, wherein the selection control means (8, FIG. 4) sets the idle-time clamping pressure such that a belt clamping force which maintains the elements of the belt on the sheave surfaces (42c, 42d, 43c, 43d) is larger than a drag torque which is generated in the forward/reverse switching mechanism.
