Abstract

To inhibit reduction of driving comfort caused by idle rotation of a primary sheave with respect to a belt during acceleration. A transmission 20 includes an input shaft 12, an output shaft 13, a primary sheave 23 that rotates together with the input shaft 12, a secondary sheave 24 that rotates together with the output shaft 13, and a belt 25 that is wound around both the primary sheave 23 and the secondary sheave 24. The transmission 20 includes a motor 22 that shifts a speed change ratio by driving a moveable sheave 23a of the primary sheave 23. A control device (an ECU 5) of the transmission 20 includes a secondary sheave rotation speed sensor 28 that detects rotation of the belt 25, and a control portion 55 of the ECU 5 performs a sheave position control (a normal control of the speed change ratio) after rotation of the belt 25 is detected after starting.
