The present invention provides an intentional slip by lowering the clutch chute pressure P of the automatic oscillation clutch 12 and the rotational speed detecting means 40. The presence or absence of slip is determined on the basis of the detected value of (42), and the coupling torque Tslip of the automatic oscillation clutch 12 is provided from the clutch hydraulic pressure P at the start of slip, and the coupling torque Tslip is slipped. It assumes the transmission torque at the previous clutch engagement.
