To provide an in-wheel motor driving device in which, even if a gear shaft mounting hole of a casing is eccentric from a regular position due to machining error, the eccentricity is corrected and the gear shaft can be mounted without eccentricity.SOLUTION: In a space between an outer diameter of a rolling bearing 49 supporting a gear shaft 36 and an inner diameter of a bearing fitting hole 73b in which the rolling bearing 49 is fitted, there are arranged an outside eccentric ring 82 in which an inner diameter is eccentric with respect to an outer diameter and an outer diameter can be turned in a range of 360° with respect to an inner diameter of a gear shaft mounting hole 73b; and an inside eccentric ring 81 in which the size of an outer diameter is the same size as the inner diameter of the outside eccentric ring 82, and an inner diameter is eccentric with respect to the outer diameter, and which can turn in the range of 360° with respect to the inner diameter of the outside eccentric ring 82. The outside eccentric ring 82 and the inside eccentric ring 81 are each relatively rotated in the range of 360°, and accordingly a shaft center of the gear shaft 36 inserted and fixed in the inner diameter of the inside eccentric ring 81 is made movable.SELECTED DRAWING: Figure 2

    【課題】 ケーシングの歯車軸取付穴が加工誤差により正規位置から偏芯していても、その偏芯を修正して歯車軸を偏芯なく取付けることができるインホイールモータ駆動装置を提供する。【解決手段】 歯車軸36を支持する転がり軸受49の外径と転がり軸受49を嵌める軸受嵌合穴73bの内径との間に、内径が外径に対して偏芯し、外径が前記歯車軸取付穴73bの内径に対して360°の範囲内で回動可能な外側偏芯リング82と、前記外側偏芯リング82の内径と同じ大きさの外径を有し、外径に対して偏芯し、前記外側偏芯リング82の内径に対して360°の範囲内で回動可能な内側偏芯リング81とを配置し、前記外側偏芯リング82と内側偏芯リング81とをそれぞれ360°の範囲内で相対回転させることにより、前記内側偏芯リング81の内径に挿入固定される前記歯車軸36の軸心を移動可能にした。【選択図】図2
