PROBLEM TO BE SOLVED: To provide a sealing device achieving sound insulation performance equivalent to that of a sealing device using double seal.SOLUTION: A sealing device 10 seals a space between a housing 20 and an operation shaft 30 penetrating through an opening part 20a of the housing 20 and includes: a fixed ring 1 fixed to the opening part 20a; a seal lip 2 which slidably adheres to an outer peripheral surface of the operation shaft 30; a bellows part 5 which elastically connects the fixed ring 1 with the seal lip 2 and may deform in a radial direction; a flange 6 fixed to a fixed ring 1 side inner periphery; and a second lip 7 which is provided continuing into an inner diameter part 52 of the bellows part 5, adheres to the flange 6 so as to slide in the radial direction, and defines a seal space 10a between the bellows part 5 and the flange 6.SELECTED DRAWING: Figure 1 |
