Abstract

PURPOSE: To provide a seal washer capable of pressing a resilient seal substantially perpendicularly and being formed without the need for particularly great processing force by having a curvature radius of the inner corner of the bending portion connecting the plate and cylindrical portion of the seal washer cap to be less than about 30% of the thickness of the plate. CONSTITUTION: A seal washer A has a resilient seal 27 made of rubber and the like, having a thickness D thicker than the height C of a cylindrical portion 25 in the inner side of a cap 21 formed by a plate 22 with a bolt hole 23, the periphery of which forms the cylindrical portion 25 via a bending portion 24. The radius of curvature of the inner corner of the bending portion of plate 22 is less than approximately 30% of the thickness T of the plate 22. When the cap 21 is compressed by a bolt and a nut, the outward expansion of the outer periphery of the resilient seal 27 is restricted inside the cylindrical portion 25 of the cap 21. The periphery of the resilient seal 27 almost does not contact the small diameter circular portion inside the bending portion 24 of the cap 21.
