摘要： A sealing structure for use in an automobile engine includes a retainer 1, a plurality of lips 2a, 2b, 2c, 2d and a metal ring 3. The retainer 1 has a main annular body made of a resin material. The lips 2a, 2b 2c, 2d are formed on the metal ring 3. After that, the metal ring 3 and the lips together are inserted in a die so as to produce the retainer 1 by an injection molding method. Thus, the retainer 1, the lips and the metal ring 3 are formed as an integral unit. Two inner lips 2a, 2d are positioned at an inner periphery of the ring 3 and contact a shaft 6 for the engine, while the other two outer lips 2b, 2c are made of a resilient or elastic material and positioned at an outer periphery of the ring 3 so that the main body of the retainer 1 supports the ring 3 and the inner lips 2a, 2d in a floating manner. (FIG. 2 A)

摘要： A sealing device comprising a projected portion having a rubber-like elastic member on the outer periphery of a seal member, an outer cylindrical portion extending toward the seal member on a flange portion of a sleeve member. This outer cylindrical portion covers an opening formed between the seal member and the flange portion, thereby preventing entry of dust. The outer cylindrical portion is further provided on the tip thereof with a bend portion which can be engaged with the projected portion. The projected portion, the outer cylindrical portion, and the bend portion form a small clearance which serves as a labyrinth seal. The projected portion is fixedly fitted with a projection ring for covering the opening formed between the seal member and the flange portion of the sleeve member so that the free end portion of the projection ring can be engaged with the flange. This free end portion of the protection ring and the flange portion form a small clearance, and this small clearance serves as a labyrinth seal.

摘要： A lip-type oil seal for use with a rotary shaft is manufactured by a method wherein different elastomeric materials for forming respectively the sealed liquid side and the atmospheric side of a tip portion of a sealing lip of the oil seal have different moduli of elasticity or hardnesses and are placed in a superposed condition within a mold prepared for vulcanization molding the oil seal. The mold is then clamped and the materials are heated and compressed so that an elastomeric material is fluidized and is vulcanization molded together with the other material to form an integral structure while a surplus portion is allowed to remain on the atmospheric side, thereby forming a sealed liquid side surface of the sealing lip. After the fluidized material has been hardened, the mold is opened and the surplus portion is then cut off, thereby forming an atmospheric side surface of the sealing lip.

摘要： 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.
