Vehicle-use automatic opening/closing device

An automatic open-close device for a vehicle that has an open-close component attached to the vehicle so as to freely open and close and a driving unit that drives the open-close component and a control unit that controls the driving unit, and automatically opens and closes the open-close component, the device comprising:

• a stop state detecting unit that detects a stop state of the open-close component that stops in an intermediate position between its fully opened position and its fully closed position thereof;
• a low driving force mode setting unit that operates the driving unit by low driving force, when the stop state detecting unit detects that the open-close component stops in the intermediate position between the fully opened position and the fully closed position thereof;
• and
• an automatic open-close mode setting unit that makes the open-close component automatically open and close, when the move speed of the open-close component in the low driving force mode becomes a specified speed or higher within a specified time;
• wherein when the vehicle is inclined in the open-close direction of the open-close component, the open-close component temporarily stops at the intermediate position and then the open-close component is automatically operated toward the downward side of the inclination.
