ABSTRACT:
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)
