ABSTRACT:
A composite step-cut type synthetic resin seal ring having a pair of abutments provided at one circumferential point of the ring body and spaced from each other. Each abutment has end face and comprises a protrusion and a shoulder provided adjacent to each other. The protrusion is provided on one axial side of the ring body and the shoulder is provided on the other axial side of the ring body. The end face, protrusion and shoulder of one abutment are complementary in shape to the end face, shoulder and protrusion of the other abutment, respectively. Chamfers are formed at the boundary between an end face of each protrusion and its inner axial side face facing the axial side face of the protrusion of the other abutment when the abutments are fitted together, at the boundary between the end face of protrusion of each abutment and its inner radial surface facing the shoulder of the other abutment when the abutments are fitted together, and at the boundary between the outer radial surface of the shoulder of each abutment and the end face of each abutment.
