Abstract
A half-open position holding apparatus for a vehicle opening and closing member includes an opening and closing member supported in a vehicle body to be openable and closable and has an opening and closing member driving unit that has a motor and a electromagnetic clutch that can put a power transmission path connecting the motor and the opening and closing member in a connected state and in a disconnected state, for driving the opening and closing member in opening and closing directions thereof, and an in-vehicle battery serving as a power source for the electromagnetic clutch. The apparatus includes a controller for controlling the opening and closing member driving unit, that, when the opening and closing member is held at a half-open position between a fully-closed position and a fully-opened position, holds the opening and closing member at the half-open position by stopping the motor, putting the electromagnetic clutch in a connected state, and controlling the electromagnetic clutch to a half-open position holding connection state such that a voltage applied to the electromagnetic clutch becomes a predetermined voltage lower than an output voltage of the in-vehicle battery.
