摘要： Provided is 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 body 120 includes a side lip 124 extending from near a distal end of an inward flange part 112 radially inward and further toward an air side (A) than a dust lip 122 to a position not as far as the outer circumferential surface of a tubular part 210. An annular member 250 is further provided, which is fixed to the outer circumferential surface of the tubular part 210 further on the air side (A) than the side lip 124 and covering an outer circumferential surface of the side lip 124 such that there is a gap between the annular member 250 itself and the outer circumferential surface of the side lip 124.

摘要： Provided is a sealing structure that allows for formation of a labyrinth structure between an oil seal and a torsional vibration damper even when the oil seal does not include a side lip. The oil seal 100 includes an oil lip 121 provided such as to be slidable on an outer circumferential surface of a tubular part 210, and a dust lip 122 provided further on an air side (A) than the oil lip 121 and slidable on the outer circumferential surface of the tubular part 210. An annular member 250 is further provided, which is fixed to the outer circumferential surface of the tubular part 210 further on the air side (A) than the dust lip 122 and covering an outer circumferential surface of the dust lip 122 such that there is a gap between the annular member 250 itself and the outer circumferential surface of the dust lip 122.

摘要： To provide a sealing structure with a torsional damper and an oil seal that can reduce exposure of a seal lip of the oil seal to foreign matter entering from around the torsional damper.
A sealing structure (1) with a torsional damper and an oil seal includes a damper pulley (10) serving as a torsional damper and an oil seal (20). The damper pulley (10) has an annular hub pocket (30) that is recessed in the outer side direction and extends in the circumferential direction along a boss part (14) of a hub (11). The oil seal (20) includes a side lip (29) that extends toward the outer side. An outer circumferential surface (31) of the hub pocket (30) increases in a diameter toward the outer side, the side lip (29) of the oil seal (20) does not enter inside the hub pocket (30), and an annular gap (g1) is formed between an outer side end (29a) of the side lip (29) and an inner side end (31a) of the outer circumferential surface (31) of the hub pocket (30).

摘要： Provided is 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 body 120 includes a side lip 124 extending from near a distal end of an inward flange part 112 of the reinforcing ring 110 radially inward and further toward an air side (A) than a dust lip 122 to a position not as far as the outer circumferential surface of a tubular part 210. The tubular part 210 includes a small-diameter part 211 on which the dust lip 122 slides, and a large-diameter part 212 on the air side (A). The large-diameter part 212 has a tapered surface 212a formed on an outer circumferential surface thereof that reduces in diameter toward the air side (A). An annular gap S is formed between this tapered surface 212a and an inner circumferential surface of the side lip 124.
