Abstract
A one-touch action type power window having a retaining circuit which continuously actuates a motor for raising or lowering window glass in response to a one-touch operation on a switch. A pick-up coil is located in the vicinity of a wire through which the motor operating current flows to generate a voltage varying in proportion to the rotational speed of the motor thereby to control the retaining circuit.
