PURPOSE:To improve a clutch in responsibility from a connection state to a disconnection state by mounting an orifice in an oil discharge path connected to the internal gap of a torque converter, with the clutch disconnected. CONSTITUTION:When a throttle angle increases, a clutch control valve 12 is changed to a left disconnection position by throttle pressure to feed oil to an oil chamber 10. In this case, oil in the internal gap 5 is discharged through the second discharge oil path L5, and the internal pressure of the gap 5 is determined to be set at comparatively low pressure by an orifice 16. Therefore, a clutch plate 9 is separated from an input case 2 by feeding oil to the oil chamber 10 so as to disconnect the clutch. |
