PROBLEM TO BE SOLVED: To smoothly lubricate a motor portion and a decelerator portion in starting a rotary pump, even in stopping for a long time under a cold environment.SOLUTION: In an in-wheel motor driving device including a motor portion A, a decelerator portion B, a bearing portion C for a wheel, a casing 22 accommodating the motor portion A and the decelerator portion B, and a lubrication mechanism supplying a lubricant to the motor portion A and the decelerator portion B by a rotary pump 56, the lubrication mechanism is disposed on a storage region of the lubricant in the casing 22, and includes a latent heat storage body 75 accommodating a latent heat storage material 73 in an exterior member 74, and impact shock application means 76 disposed near the latent heat storage body 75, and applying impact shock to the latent heat storage material 73 in the exterior member 74.SELECTED DRAWING: Figure 1

    【課題】 寒冷環境下で長時間停止した場合であっても、回転ポンプの始動時にモータ部および減速機部の潤滑を円滑に行う。【解決手段】 モータ部Aと、減速機部Bと、車輪用軸受部Cと、モータ部Aおよび減速機部Bを収容したケーシング22と、回転ポンプ56によりモータ部Aおよび減速機部Bに潤滑油を供給する潤滑機構とを備えたインホイールモータ駆動装置であって、潤滑機構は、ケーシング22内の潤滑油の貯溜部位に配置され、潜熱蓄熱材73を外装部材74内に収納した潜熱蓄熱体75と、その潜熱蓄熱体75に近接配置され、外装部材74内の潜熱蓄熱材73に衝撃を付与する衝撃付与手段76とを具備する。【選択図】 図1
