Abstract
A sealing structure that allows for formation of a side lip, as well as a labyrinth structure between an oil seal and a torsional vibration damper, even when a reinforcing ring has a short inward flange part. The sealing bodyincludes a side lipextending from near a distal end of an inward flange partof the reinforcing ringradially inward and further toward an air side (A) than a dust lipto a position not as far as the outer circumferential surface of a tubular part. The tubular partincludes a small-diameter parton which the dust lipslides, and a large-diameter parton the air side (A). The large-diameter parthas a tapered surfaceformed on an outer circumferential surface thereof that reduces in diameter toward the air side (A). An annular gap S is formed between this tapered surfaceand an inner circumferential surface of the side lip
