To provide an in-wheel motor type drive unit which enables a burden of an electric motor which continuously drives in a high load state and enables reduction of magnetic resistance and electric resistance of the electric motor.SOLUTION: An in-wheel motor type drive unit has: an electric motor 2; a hub carrier 4 which is rotated by rotation of the electric motor 2; a case member 5 which rotatably holds the hub carrier 4; and a rotation transmission mechanism which is housed in the case member 5 and transmits the rotation of the electric motor 2 to the hub carrier 4. The rotation transmission mechanism includes multiple disc clutches 7, 8 and a two-way clutch 9 serving as a transmission mechanism for changing a speed of the rotation of the electric motor 2. The two-way clutch 9 includes a ratchet mechanism.SELECTED DRAWING: Figure 2

    【課題】 高負荷状態で連続駆動している電動モータの負担を低減し、さらに電動モータの磁気抵抗および電気抵抗を低減することができるインホイールモータ型駆動ユニットを提供すること。【解決手段】電動モータ2と、電動モータ2の回転によって回転するハブキャリア4と、ハブキャリア4を回転可能に保持するケース部材5と、ケース部材5に収容され、電動モータ2の回転をハブキャリア4に伝達する回転伝達機構と、を有するインホイールモータ型駆動ユニットにおいて、回転伝達機構は、電動モータ2の回転を変速する変速機構として多板クラッチ7、8と二方向クラッチ9とを含み、二方向クラッチ9は、ラチェット機構を備えることを特徴とする。【選択図】図2
