To provide an in-wheel motor driving device which enables a wheel speed detector to be arranged without affecting a length of the in-wheel motor driving device as seen in an axle direction and enables control of a gap between a detected part and a rotary sensor to be easily performed.SOLUTION: A wheel speed detector (6) includes: a detected part (61) which is disposed in a hat part (52) of a brake rotor (5) and generates flux change in a circumferential direction; and a rotary sensor (62) which is attached to an outer ring (13) of an inner ring rotation type wheel hub bearing part (11) or a hub support member supporting the outer ring so as to face the detected part.SELECTED DRAWING: Figure 1

    【課題】インホイールモータ駆動装置の車軸方向長さに影響することなく車輪速検出装置を配置でき、かつ、被検出部と回転センサとの間のギャップ管理を容易に行えるようにすること。【解決手段】車輪速検出装置(6)は、ブレーキロータ(5)のハット部(52)内に配置され、円周方向に磁束変化を生じさせる被検出部(61)と、被検出部と対面するように、内輪回転タイプの車輪ハブ軸受部(11)の外輪(13)、または、外輪を支持するハブ支持部材に取り付けられた回転センサ(62)とを備える。【選択図】図1
