A travel device (11) is provided with: a cylindrical mandrel (12) that rotatably supports a wheel attachment cylinder (17) to which a wheel (7) is attached; an electric motor (13) attached to the mandrel (12); a motor shaft (14) that protrudes from the electric motor (13) and outputs the rotation of the electric motor (13); a rotating shaft (15) to which the rotation of the motor shaft (14) is transmitted; a speed reduction mechanism (21) that decelerates the rotation of the rotating shaft (15) and transmits the rotation to the wheel mounting tube (17); a lubricating oil circulation circuit (50) that repeatedly supplies lubricating oil (L) to the speed reduction mechanism (21); and a coupling (38) that couples the motor shaft (14) and the rotating shaft (15). The coupling (38) is provided with a lubricating oil passage (43) that supplies part of the lubricating oil (L) supplied to the speed reduction mechanism (21) by the coupling part lubrication circuit (50) to the coupling part of the motor shaft (14) and the coupling (38).
行驶装置(11)具有:筒状的心轴(12),其能够旋转地支承供车轮(7)安装的车轮安装筒(17);电动马达(13),其安装于心轴(12);马达轴(14),其从电动马达(13)突出且输出电动马达(13)的旋转;旋转轴(15),其传递马达轴(14)的旋转;减速机构(21),其将旋转轴(15)的旋转减速并向车轮安装筒(17)传递;润滑油循环回路(50),其向减速机构(21)反复供给润滑油(L);和联轴器(38),其将马达轴(14)与旋转轴(15)之间结合。在联轴器(38)设有润滑油通路(43),润滑油通路(43)将由结合部润滑回路(50)向减速机构(21)供给的润滑油(L)的一部分向马达轴(14)与联轴器(38)的结合部供给。
