PROBLEM TO BE SOLVED: To properly supply a lubrication oil to a portion needing lubrication or cooling with a simple structure.SOLUTION: A lubrication oil supply structure in an in-wheel motor drive device (10) includes: an oil tank (47) which is provided at a lower part of a motor part (21) and/or a speed reduction part (31) and stores a lubrication oil; an oil pump (54) which pumps the lubrication oil from the oil tank; and an oil pipe (70) which is fixedly attached to an upper part of the motor part and/or the speed reduction part. The oil pipe (70) includes: an inflow port (76) into which the lubrication oil pumped by the oil pump (54) flows; and at least one outflow port (77) which is provided from one end to the other end and discharges the lubrication oil flowing from the inflow port (76) in a downward direction.SELECTED DRAWING: Figure 1
【課題】簡易な構造で、潤滑または冷却が必要な部位に的確に潤滑油を供給する。【解決手段】インホイールモータ駆動装置(10)における潤滑油の供給構造は、モータ部(21)および/または減速部(31)の下部に設けられ、潤滑油を貯留するオイルタンク(47)と、オイルタンクから潤滑油を汲み上げるオイルポンプ(54)と、モータ部および/または減速部の上部に取り付け固定されるオイル管(70)とを備える。オイル管(70)は、オイルポンプ(54)により汲み上げられた潤滑油が流入する流入口(76)と、一端から他端までの間に設けられ、流入口(76)から流入した潤滑油を下方に向けて吐出する少なくとも1つの流出口(77)とを含む。【選択図】図1
