Power window regulator apparatus
 A regulator for a power window having a safety function for preventing an object from being caught in a closing power window includes a driving unit for raising and lowering the window glass of a vehicle and a driven unit which receives power from the driving unit. When frictional resistance corresponding to relative displacement between the driving and driven units is less than a fixed value during descent of the window glass and exceeds this fixed during ascent of the window glass, the ascending window glass is reversed and made to descend. When the amount of an increase in current to the driving unit during ascent of the window glass increases in a case where the sliding resistance has exceeded a fixed value even once during descent of the window glass, the ascending window glass is reversed and made to descend.
