Abstract
A sealing structure with a torsional damper and an oil seal includes a damper pulley serving as a torsional damper and an oil seal. The damper pulley has an annular hub pocket that is recessed in the outer side direction and extends in the circumferential direction along a boss part of a hub. The oil seal includes a side lip that extends toward the outer side. An outer circumferential surface of the hub pocket increases in a diameter toward the outer side, the side lip of the oil seal does not enter inside the hub pocket, and an annular gap is formed between an outer side end of the side lip and an inner side end of the outer circumferential surface of the hub pocket.
