Zusammenfassung:A seal washer of the present invention includes a metal washer body 10 including a center hole 11, an outer resilient material 17 projecting from an outer periphery of the washer body 10 to a location lower than a lower surface of the washer body 10, and an inner resilient material 20 provided on an inner periphery of the washer body 10 which faces the center hole 11. If a fastening force in an axial direction is applied, since the lower surface 15 of the washer body 10 metal-touches on a mating member, loosening does not occur unlike a conventional technique. In addition, since no further compression load is applied to the resilient material 17, a phenomenon that the resilient material 17 is deformed in a crushed manner does not occur.
