PURPOSE: To discharge excessive oil and water contents in the inside of the rotary joint. CONSTITUTION: A pool H1 to pool a fluid is arranged in the vicinity of a shaft P on the inner circumferential part of a face to which two rotating bodies B1 , B2 oppose in a rotary joint 100 where the two rotating bodies B1 , B2 are fitted to the shaft P via, e.g. bearings so that the two rotating bodies B1 , B2 are rotated around the shaft P relatively while opposing to each other. Then a drain groove H2 is provided to discharge the fluid along a face A to which the two rotating bodies B1 , B2 oppose from the pool H1 to the outer circumference of the two rotating bodies B1 , B2 . A centrifugal force is exerted to the fluid in the pool attended with the rotation of the two rotating bodies B1 , B2 and the fluid is naturally discharged along the drain groove H2 . |
