Claims

[Scope of utility model registration request]

An actuator that connects and disconnects a clutch between the engine and transmission of a vehicle, an air supply solenoid valve installed in a passage that introduces working air into the air chamber of this actuator, and a duty pulse signal that connects the air in the air chamber. The exhaust solenoid valve opens to the atmosphere at a time ratio according to the ratio, and the air supply solenoid valve is controlled to open, and the gear position of the transmission is controlled to change, and then the exhaust solenoid valve is opened by a pulse signal. unit, an emergency switch that is manually operated in the event of an abnormality in the control unit, and an emergency switch that controls the opening of the air supply solenoid valve in accordance with the switch operation of the emergency switch to operate the transmission at a predetermined time. An automatic transmission device comprising: a gear shift circuit that controls the exhaust electromagnetic valve to be open for a certain period of time after switching to a gear position. 5
