Abstract
A wiper is pivotably supported and is swung by a drive force of an electric motor. When a command, which commands execution of one of high and low speed modes, is entered through a wiper switch in the middle of operation of the wiper in another one of the high and low speed modes, a control unit controls an electric motor such that a moving speed of the wiper, which is preset for the another one of the high and low speed modes, is changed to the moving speed of the wiper, which is preset for the one of the high and low speed modes, during a time period of executing a predetermined number of swings of the wiper between an upper return position and a lower return position upon entering of the command through the wiper switch means.
