ABSTRACT:
An oil seal disposed between a housing and a rotating shaft received in the hollow inside of the housing so as to prevent a liquid in the housing from leaking to the outside. The oil seal has a first metal ring and a second metal ring. The first metal ring is secured at the outer peripheral portion thereof to the housing and is provided at the inner peripheral portion thereof with an annular seal lip which is in slide contact with the outer peripheral surface of the rotating shaft thereby to seal the liquid in the housing. The second metal ring is connected at the outer peripheral portion thereof to the outer peripheral portion of the first metal ring and is separated at the inner peripheral portion thereof from the inner peripheral portion of the first metal ring in the axial direction of the rotating shaft so as to form an annular space in cooperation with the first metal ring. The second metal ring further has a dust lip which is in slide contact with the outer peripheral surface of the rotating shaft. The seal lip is constituted by a main lip located on the side thereof which is closer to the liquid to be sealed and a subsidiary lip located on the side thereof which is closer to the dust lip. Further, the dust lip is provided in its slide contact surface for slide contact with the rotating shaft with a circumferentially continuous groove.
