A travel device (11) is provided with: a coupling (38) that couples a motor shaft (14) and a rotating shaft (15); a coupling housing (46) fitted to the outer peripheral surface of the coupling (38); a coupling oil passage (43) that is provided to the coupling (38) and that supplies lubricating oil (L) to spline coupling sections (39A, 40A) between the motor shaft (14) and the rotating shaft (15) and the coupling (38); and a housing oil passage (47) that is provided in the joint housing (46) and guides a portion of the lubricating oil (L) to the joint oil passage (43). The coupling housing (46) is provided with an oil storage section (50) that stores lubricating oil (L) supplied to spline coupling sections (39A, 40A) between the motor shaft (14) and the rotating shaft (15) and the coupling (38), and the oil storage section (50) has a shape in which the capacity of a portion positioned on the radially upper side of the coupling housing (46) increases.
行驶装置(11)具备:联轴器(38),其将马达轴(14)与旋转轴(15)之间结合;联轴器壳体(46),其与联轴器(38)的外周面嵌合;联轴器油路(43),其设置于联轴器(38),向马达轴(14)以及旋转轴(15)与联轴器(38)的花键结合部(39A)、(40A)供给润滑油(L);以及壳体油路(47),其设置于联轴器壳体(46),将润滑油(L)的一部分向联轴器油路(43)引导。在联轴器壳体(46)设置有贮油部(50),该贮油部(50)贮存向马达轴(14)以及旋转轴(15)与联轴器(38)的花键结合部(39A)、(40A)供给的润滑油(L),贮油部(50)具有位于联轴器壳体(46)的径向上侧的部位的容量变大的形状。
