PURPOSE:To make a slide door structure compact by a method in which a spiral shaft is turned by a driver to allow a slide part to travel, and a four-joint link mechanism is turned around a supporting point in coordination with the slide part to open or close a door. CONSTITUTION:When a switch is closed and a power source circuit is connected to a power source, a closing switch is closed. An earthing circuit is then interrupted, and a drive motor 22 is operated through the power source circuit and the relay coil excited to close the relay contact. An electric current is then supplied to an actuator 23 through the power source circuit to turn a cam shaft 20 through a given angle. Also, a clutch part is rocked around a support shaft and a female screw is engaged with a spiral shaft 21 to allow the slide part 24 to move in the closing direction of door. A four-joint link mechanism 25 is turned around a joint 25a to close the slide door along a guide rail 4. |
