Abstract
A shaft has an outer circumferential surface provided with a recessed portion in which a cooling medium is accommodated. A roller is rotatable relative to the outer circumferential surface of the shaft. A radial sliding bearing supports the roller to be rotatable relative to the outer circumferential surface of the shaft. A floating seal includes a rotating-side member that is supported by the roller and a fixed-side member that slides together with the rotating-side member. In a radial direction of the shaft, the recessed portion faces: a sliding portion between the rotating-side member and the fixed-side member in the floating seal: and the radial sliding bearing.
