An oil seal that faces the outside of the machine and has a second metal ring closely fitted and attached to the stationary side, a dust cover that is located on the outside of the oil seal and attached to the rotating side, and the second metal ring periphery where the equipped with muddy water seal lip slidably brought into close contact with the dust cover, the outer peripheral tube portion formed in the dust cover while being integrally formed is formed on the first metal ring of the oil seal It extends so as to surround the outer peripheral side of the cylindrical portion.

また、請求項２の発明に係る密封装置は、第一の金属環に対油シールリップが一体に成形されると共に前記第一の金属環に機外側に面して第二の金属環が密接嵌合され静止側に取り付けられるオイルシールと、このオイルシールの機外側に位置して回転側に取り付けられるダストカバーと、前記第二の金属環に一体に成形されると共に前記ダストカバーに摺動可能に密接される対泥水シールリップを備え、前記ダストカバーに形成された外周筒部が前記静止側の外周側を包囲するように延びるものである。According to a second aspect of the present invention, an oil seal lip is integrally formed on the first metal ring, and the second metal ring is in close contact with the first metal ring facing the outside of the machine. An oil seal that is fitted and attached to the stationary side, a dust cover that is located on the outer side of the oil seal and that is attached to the rotating side, and is integrally formed with the second metal ring and slides on the dust cover An anti-muddy water seal lip that can be brought into close contact is provided, and an outer peripheral cylindrical portion formed on the dust cover extends so as to surround the outer peripheral side of the stationary side.

また、請求項３の発明に係る密封装置は、第一の金属環に対油シールリップが一体に成形されると共に前記第一の金属環に機外側に面して第二の金属環が密接嵌合され静止側に取り付けられるオイルシールと、このオイルシールの機外側に位置して回転側に取り付けられるダストカバーと、前記ダストカバーに一体に成形されると共に前記第二の金属環のフランジ部に摺動可能に密接される内周側の対泥水シールリップと、前記ダストカバーに一体に成形されると共に前記第二の金属環の外周筒部の内周面に摺動可能に密接される外周側の対泥水シールリップと、を備え、前記ダストカバーに形成された外周筒部が前記オイルシールの第一の金属環に形成された外周筒部の外周側を包囲するように延びるものである。According to a third aspect of the present invention, an oil seal lip is integrally formed on the first metal ring, and the second metal ring is in close contact with the first metal ring facing the outside of the machine. An oil seal that is fitted and attached to the stationary side, a dust cover that is located on the outer side of the oil seal and that is attached to the rotating side, and a flange portion that is integrally formed with the dust cover and that is formed on the second metal ring The muddy water seal lip on the inner peripheral side that is slidably in contact with the inner surface and the dust cover are formed integrally with the inner peripheral surface of the outer peripheral cylindrical portion of the second metal ring. An outer peripheral side anti-muddy water seal lip, and the outer peripheral cylindrical portion formed on the dust cover extends so as to surround the outer peripheral side of the outer peripheral cylindrical portion formed on the first metal ring of the oil seal. is there.
