A shaft (21) has a recessed portion (21ea) for accumulating a cooling medium on an outer circumferential surface (21aa). A roller (22a) is rotatable with respect to the outer circumferential surface (21aa) of the shaft (21). A radial sliding bearing (23aa) supports the roller (22a) rotatably with respect to the outer circumferential surface (21aa) of the shaft (21). A floating seal (26a) has a rotating-side member (26aR) supported by the roller (22a), and a fixed-side member (26aF) that slides with the rotating-side member (26aR). The recessed portion (21ea) faces both a sliding portion of the rotating side member (26aR) and the fixed side member (26aF) of the floating seal (26a) and the radial sliding bearing (23aa) in the radial direction of the shaft (21).

    轮轴(21)在外周面(21aa)具有用于积存冷却介质的凹部(21ea)。轮体(22a)能够相对于轮轴(21)的外周面(21aa)旋转。径向滑动轴承(23aa)将轮体(22a)支承为能够相对于轮轴(21)的外周面(21aa)旋转。浮动密封(26a)具有支承于轮体(22a)的旋转侧构件(26aR)和与旋转侧构件(26aR)滑动的固定侧构件(26aF)。凹部(21ea)在轮轴(21)的径向上对置于浮动密封(26a)中的旋转侧构件(26aR)与固定侧构件(26aF)的滑动部和径向滑动轴承(23aa)这两者。
