PROBLEM TO BE SOLVED: To reduce a delay in extension and convergence of a wiper arm which is synchronized with reciprocation operation of the wiper arm.SOLUTION: A microcomputer 58 controls a rotation angle of an output shaft of a second motor 12 based on a rotation angle map in which a timing of rotation control for the output shaft of the second motor 12 to a rotation angle of an output shaft of a first motor 11 which is stored in a memory 60 is accelerated, and an actual rotation angle of the output shaft of the first motor 11, thereby normally rotating the output shaft of the first motor 11 and moving a front passenger seat side wiper blade 36 from a lower inversion position P2P to an upper inversion position P1P. During such a movement, the microcomputer normally rotates the output shaft of the second motor 12 thereby moving a fifth axis L5, which is a fulcrum of a front passenger seat side wiper arm 35, in an angle direction above the front passenger seat side on a wind shield glass 1, and until the front passenger seat side wiper arm 36 arrives at the upper inversion position P1P, the microcomputer reversely rotates the output shaft of the second motor 12 thereby returning a position of the fifth axis L5 to an original position.SELECTED DRAWING: Figure 1

    【課題】ワイパアームの往復動作に同期するワイパアームの伸長及び収束における遅延を低減させる。【解決手段】マイクロコンピュータ58は、メモリ60に記憶されている第1モータ11の出力軸の回転角度に対する第2モータ12の出力軸の回転制御のタイミングを早めた回転角度マップと、第1モータ11の出力軸の実際の回転角度と、に基づいて第2モータ12の出力軸の回転角度を制御することにより、第1モータ11の出力軸を正回転させて助手席側ワイパブレード36を下反転位置P2Pから上反転位置P1Pへ移動させている間に、第2モータ12の出力軸を正回転させて、助手席側ワイパアーム35の支点である第5軸線L5をウィンドシールドガラス1上の助手席側上方の角方向に移動させ、助手席側ワイパブレード36が上反転位置P1Pに到達するまでに第2モータ12の出力軸を逆回転させて第5軸線L5の位置を元に戻す。【選択図】図1
