To provide a wheel driving device having an in-wheel motor structure, which enables a rotation detecting device to detect rotation properly.SOLUTION: A rotary electric machine 12 is stored inside in a radial direction of a cylindrical wheel 11. The rotary electric machine 12 has a rotator 30 that rotates together with a rotating shaft 36, and a stator 40 arranged to oppose to inside in a radial direction of the rotator 30. The stator 40 has a stator winding 41, and a cylindrical stator core 42 assembled to the inside in a radial direction of the stator winding 41 to hold the stator winding 41 and a stator holder 43. A rotation sensor 80 that detects rotation of the rotating shaft 36 is mounted on the stator holder 43. A refrigerant passage 48 through which refrigerants are passed is provided at a part to be mounted on which the rotation sensor 80 is mounted in a holder end plate part 45.SELECTED DRAWING: Figure 4

    【課題】インホイールモータ構造の車輪駆動装置において回転検出装置による回転検出を適正に行わせる。【解決手段】回転電機12は、円筒状の車輪11の径方向内側に収容されている。回転電機12は、回転軸36と一体回転する回転子30と、その回転子30の径方向内側に対向配置される固定子40とを有している。固定子40は、固定子巻線41と、その固定子巻線41の径方向内側に組み付けられた状態で固定子巻線41を保持する円筒状の固定子コア42及び固定子ホルダ43とを有している。固定子ホルダ43には、回転軸36の回転を検出する回転センサ80が取り付けられている。ホルダ端板部45において回転センサ80が取り付けられる被取付部には、冷媒を流通させる冷媒通路48が設けられている。【選択図】 図4
