PROBLEM TO BE SOLVED: To realize a driving device which enables a wheel speed sensor to be provided while achieving downsizing of the device in an axial direction.SOLUTION: A wheel speed sensor 40 is disposed at a position which is located at an outer side of a motor case 20 in a radial direction R and overlaps with the motor case 20 when viewed in the radial direction R. Further, the wheel speed sensor 40 is disposed so as to face a detected part 5 provided at a hub 30 or a member, which integrally rotates with the hub 30, in an axial direction L.SELECTED DRAWING: Figure 1 【課題】装置の軸方向の小型化を図りつつ車輪速センサを設けることが可能な駆動装置を実現する。【解決手段】車輪速センサ４０は、モータケース２０に対して径方向Ｒの外側であって、径方向Ｒに見てモータケース２０と重なる位置に配置されている。更に、車輪速センサ４０は、ハブ３０又はハブ３０と一体回転する部材に設けられた被検出部５に対して、軸方向Ｌに対向するように配置されている。【選択図】図１
