A drive control device for an opening/closing member may be advantageously utilized in vehicular power window systems and the like. The drive control device is active to detect occurrence of pinching of an object obstructing the path of motion of the opening/closing member and, upon detection of such pinching during closing operation is controlled so as to move in the opening direction for a predetermined distance for preventing serious pinching from being applied to, for example, a persons hand or arm which may be blocking a power window while being closed by a vehicle driver. The drive control device further includes timing functions such that closing operation may not be immediately resumed after pinch detection, until a predetermined time period has elapsed. The pinch detection operation is effective to compensate for overrun of the opening/closing member caused by a lag between the time a closing control signal is stopped and the acutal motion of the opening/closing member finally and completely stops.
