PROBLEM TO BE SOLVED: To provide a vehicle motor drive unit which can change block torque by a vehicle speed, can easily switch torque transmission and block, and can reduce a manufacturing cost or the like more than a prior art which has taken a higher safety rate more than that at a normal time, and a vehicle having the vehicle motor drive unit.SOLUTION: This vehicle motor drive unit comprises a motor 1, and a torque transmission device 3 for transmitting the torque of the motor 1 to wheels 2. The torque transmission device 3 has a torque limiter function part 8 in which block torque for blocking torque transmission becomes small as a vehicle speed becomes high. The torque limiter function part 8 has: engaged members 54 and 55 which are rotatably arranged around the same rotating axial cores while facing each other, and have engagement grooves extending to a radial direction at opposing faces; engagement bodies 56 which are arranged at both the engagement grooves of the engaged members 54 and 55, and perform the torque transmission; and energization means for energizing the engagement bodies 56.SELECTED DRAWING: Figure 1

    【課題】 遮断トルクを車速により変化させることができ、またトルク伝達と遮断とを容易に切り換えることができると共に、安全率を通常よりも大きくとった先行技術よりも製造コスト等の低減を図ることができる車両用モータ駆動装置およびその車両用モータ駆動装置を備えた車両を提供する。【解決手段】 この車両用モータ駆動装置は、モータ1と、モータ1のトルクを車輪2に伝達するトルク伝達装置3とを備える。トルク伝達装置3は、車速が速くなるに従って、トルク伝達を遮断する遮断トルクが小さくなるトルクリミッタ機能部8を有する。トルクリミッタ機能部8は、互いに対向して同一の回転軸心回りに回転自在に設けられて対向面に径方向に延びる係合溝を有する被係合部材54,55と、被係合部材54,55の係合溝の両方に保持されてトルク伝達を行う係合体56と、係合体56を付勢する付勢手段とを有する。【選択図】 図1
