An output shaft extending from a casing of a power transmission device is fitted into an inner joint member of a constant-velocity universal joint, and a sealing device is provided to cover the gap between an outer joint member of the constant-velocity universal joint and the casing. The sealing device has a bendable and extendable boot that encloses the gap between the outer joint member of the constant-velocity universal joint and the casing. The boot is mounted at one end on the outer joint member side of the constant-velocity universal joint via a bearing structure section, and is mounted at the other end on the casing. Rotation that would accompany the rotation of a propeller shaft is thereby restricted. |
