PROBLEM TO BE SOLVED: To provide a wiper motor which can prevent that a fixed terminal and a movable terminal are unintentionally short-circuited.SOLUTION: A wiper motor has an electric motor, an output gear 40 for transmitting a rotation force of the electric motor to a wiper arm, a power supply circuit for supplying a current to the electric motor, and a casing for accommodating the output gear 40. The power supply circuit comprises a relay plate 64 attached to the output gear 40, and a motor contact plate 73 and an earth contact plate 74 which are supported to the casing. The relay plate 64 has a first contact point 65 and a second contact point 66 which are arranged in different positions in a rotation direction of the output gear 40, and a disc circular part 67 for connecting the first contact point 65 and the second contact point 66. The motor contact plate 73 and the earth contact plate 74 are arranged in different positions in the rotation direction of the output gear 40.SELECTED DRAWING: Figure 8

    【課題】固定端子と可動端子とが不用意に短絡することを防止できるワイパモータを提供する。【解決手段】電動モータと、電動モータの回転力をワイパアームに伝達する出力ギヤ40と、電動モータに電流を供給する電源回路と、出力ギヤ40を収容するケーシングと、を有するワイパモータであって、電源回路は、出力ギヤ40に取り付けたリレープレート64と、ケーシングに支持されたモータ用コンタクトプレート73及びアース用コンタクトプレート74と、を備え、リレープレート64は、出力ギヤ40の回転方向で互いに異なる位置に配置された第1接点部65及び第2接点部66と、第1接点部65と第2接点部66とを接続する円弧部67と、を有し、モータ用コンタクトプレート73とアース用コンタクトプレート74とが、出力ギヤ40の回転方向で互いに異なる位置に配置されている。【選択図】図8
