PROBLEM TO BE SOLVED: To provide a technology for an in-wheel motor driving apparatus for a steering wheel, in which folding and extension of power line upon steering is reduced, and to provide an in-wheel motor driving apparatus in which inner space of a vehicle body is not use as a sacrifice.SOLUTION: An in-wheel motor driving apparatus (10) comprises a motor part (21) comprising a power line connecting part (91), and a foldable power line (93) whose one end is connected to the power line connecting part, whose another end extends to a vehicle body (101) outside of a casing of the in-wheel motor driving apparatus, and which supplies electric power from the vehicle body to the motor part, and which is attached on a vehicle body side member in a manner that it may be steered on a steering axis line extending in a vertical direction. Angle between an extending direction of one end part of the power line held by the power line connecting part and a criterion line parallel with an axis line (O) of a wheel hub (12) upon straight traveling is a predetermined value (θ) within a range of 10° or more and 90° or less when seen toward the vertical direction.SELECTED DRAWING: Figure 9
【課題】転舵輪のインホイールモータ駆動装置に関し、転舵時の動力線の曲げ伸ばしを低減する技術を提供することを目的とする。また車体の内部空間が犠牲にならないインホイールモータ駆動装置を提供する。【解決手段】インホイールモータ駆動装置(10)は、動力線接続部(91)を有するモータ部(21)と、一端が動力線接続部と接続し、他端がインホイールモータ駆動装置のケーシング外部の車体(101)まで延び、車体からモータ部へ電力を供給する屈曲可能な動力線(93)とを備え、上下方向に延びる転舵軸線を中心として転舵可能に車体側メンバに取り付けられる。動力線接続部に保持される動力線の一端部の延在方向と、直進時の車輪ハブ(12)の軸線(O)に平行な基準線とがなす角度が、上下方向にみて、10°以上90°以下の範囲に含まれる所定値(θ)である。【選択図】図9
