It is.
- the sound insulating member of the sound insulating seal is in contact with the mounting portion of the seal body at the outer peripheral portion and the same seal at the inner peripheral portion. Since it is structured to be held by the seal body in contact with the seal lip of the body, the radial direction that allows the passage of transmitted sound as in the prior art in FIG. A gap will not be formed. Further, since the bellows are not arranged in the two axial directions as in the prior art of FIG. 4, it is possible to prevent the axial length of the sealing device from increasing.

- the sound insulation seal 7 has a sound insulation member 20 held in a sound insulation seal holding space 15 provided in the seal body 6, and the sound insulation member 20 is an elastic body, for example, a sponge-like foam material ( For example, it is formed into an annular shape by Super Seal (registered trademark) manufactured by Nippon Hojo Co., Ltd.
- the sound insulation member 20 has an outer diameter D equal to or larger than a diameter of the sound insulation seal holding space 15 (inner diameter of the rubber-like elastic body 12 of the mounting portion 8) d. And the inner diameter D is set to
- the outer diameter 14 of the outer peripheral portion 14a is formed smaller than the outer diameter d.
- the outer peripheral portion 20a is in contact with the mounting portion 8 and the inner peripheral portion 20b is in contact with the seal lip portion 9. Specifically, the outer peripheral portion 20a comes into contact with the inner peripheral surface of the rubber elastic body 12, and the inner peripheral portion 20b comes into contact with the outer peripheral portion 14a of the bumper 14 specifically.
- the sound insulation member 20 is formed into a rectangular cross section before assembly!

- the sound insulation member 20 is held by the seal body 6 in contact with the mounting portion 8 at the outer peripheral portion 20a and in contact with the seal lip portion 9 at the inner peripheral portion 20b. Therefore, the conventional technology shown in FIG. A radial gap that allows the passage of transmitted sound is not formed. Therefore, since the sound insulating member 20 completely closes the space between the mounting portion 8 and the seal lip portion 9 to form a double structure with respect to the bellows portion 10, the sound transmitted through the bellows portion 10 is effectively absorbed. Thus, the sound insulation performance can be improved.
- the sound insulating member 20 comes into contact with the shaft 4 made of a metal material. Although there is a concern that early fatigue such as sag and wear may occur in 20, in the above configuration, the sound insulating member 20 contacts the seal lip portion 9 made of an elastic body, not the metal shaft 4. Accordingly, it is possible to suppress the early fatigue of the sound insulating member 20.
- the sound insulation member 20 is supported by a lip-shaped sound insulation seal support portion 17 provided in the mounting portion 8, and interferes with the seal lip portion 9 and is pressed by the seal lip portion 9 to be partially 20c. Therefore, a radial gap is generated between the sound insulation member 20 and the seal lip portion 9. Therefore, the sound insulation performance can be improved also from this point.
- the sound insulation member 20 supported by the sound insulation seal support portion 17 and pressed by the seal lip portion 9 has an effect that the sound insulation member 20 is not easily detached from the seal body 6 without taking measures such as adhesion.
