PURPOSE:To reduce the perceived burden of an operator and to promote safety by automatically opening and closing side windows for a car in required positions by variable resistance type slide control switches, forward and reverse motors and rotary type potentiometer. CONSTITUTION:An automatic opening and closing device of side doors for a car is constituted of variable resistance type slide control switches S provided to each of doors 15, etc., as the number of articles corresponding to side windows W for a car, forward and reverse motors 18 built in the doors 15 so that each of the side doors W is raised and lowered and rotary type potentiometers to detect a position of an extent that the side window is currently opened and closed by integrating the potentiometer into a unit on the rotary shaft of each of the motors 18. The motors 18 are rotated forward and reversely by slide control position designation of the control switches S to open and close the side windows W by an extent corresponding to the designation. According to the constitution, the side windows W can be opened and closed in required positions by only slide control of the control switches S. |
