PURPOSE: To provide a window regulator equipped with an insertion preventive function in which there is no need to arrange sensors in a wide range, and which is high in detection capacity. CONSTITUTION: If door glass hits upon an obstacle, the tension of the tape for raising the door glass increases, and the guide body 40 retained by a guide receiver 44 shifts in the direction of an arrow A. By this guide body 40, a piezoelectric element 48 is nipped to generate voltage. This generated voltage is sent to a controller after being amplified with an amplifier. Here, the obstacle can be prevented from nipped between the door glass and the window frame by the controller reversing a motor by a specified amount and stopping it. |
