To provide an electric winch device for a vehicle capable of reducing/preventing the occurrence of problems such as a failure in an oil seal even when a wet multiplate type brake is used.SOLUTION: An electric winch device (1) for a vehicle includes a motor (20), a case part (30) covering at least a part of an output shaft (25) of the motor (20), an oil seal (27) supporting the output shaft (25), a rotating drum (10) winding up or feeding out a wire (11), a deceleration mechanism part (40), a first transmission shaft (60) having a connection part (62) always connected to the output shaft (25), a second transmission shaft (70) being engaged with the first transmission shaft (60) and transmitting the output torque of the motor (20) to the deceleration mechanism part (40), and a wet multiplate brake part (50) provided on one end side of the first transmission shaft (60). A recessed part (30a) is provided at a position over an external wall of the case part (30), vertically above an axis of the output shaft (25) and opposite to the output shaft (25).SELECTED DRAWING: Figure 1

    【課題】湿式多板式ブレーキを用いても、オイルシールに不具合等の問題が生じることを軽減・防止することができる車両用電動ウインチ装置を提供すること。【解決手段】車両用電動ウインチ装置(1)は、モータ(20)と、モータ(20)の出力軸(25)の少なくとも一部を覆うケース部(30)と、出力軸(25)を支持するオイルシール(27)と、ワイヤ(11)を巻取り又は巻出しする回転ドラム(10)と、減速機構部(40)と、出力軸(25)と常時連結する連結部(62)を有する第1伝達軸(60)と、第1伝達軸(60)に係合し、モータ(20)の出力トルクを減速機構部(40)へと伝達する第2伝達軸(70)と、第1伝達軸(60)の一端側に設けられる湿式多板ブレーキ部(50)と、を具備し、ケース部(30)の外壁上であって、出力軸(25)の軸線よりも鉛直上方且つ出力軸(25)に対向する位置に、凹部(30a)が設けられる。【選択図】 図1
