徴とする請求項１記載の車両用自動変速装置。[Scope of Claim for Utility Model Registration] (1) The transmission actuator changes gears based on the command from the control unit based on the signal from the shift lever position detection means, and the driver's clutch pedal operation or from the air reservoir to the clutch booster. In automatic transmission systems for vehicles, the mechanical clutch is connected and disconnected by supplying compressed air to the clutch booster by controlling the opening and closing of a solenoid valve in the air piping connected to the air piping via a double check valve. Clutch connection/disconnection detection means for detecting connection/disconnection of the clutch and inputting the detection signal to the control unit; and gear change operation detection means for detecting gear change operation and inputting the detection signal to the control unit. When the clutch is disengaged and the gear shifting operation is completed based on the detection signals from the contact detection means and the gear shifting operation detection means, the control unit energizes the solenoid valve for a certain period of time to open the air pipe and compress the clutch booster. An automatic transmission device for a vehicle characterized by supplying air. (2) The gear shift operation detection means includes the shift lever position detection means and a gear position detection means for detecting the position of the transmission gear, and these detection signals determine the shift lever position and the transmission gear position. and when the clutch is disengaged according to a detection signal from the clutch disengagement detection means, the electromagnetic valve is energized for a certain period of time in response to a command from the control unit to supply compressed air to the clutch booster. The automatic transmission device for a vehicle according to claim 1, characterized in that:
