Claims

[Scope of utility model registration request]

Two or more parts having through holes, a flat rubber gasket interposed between the parts, a cylindrical rubber gasket with a convex cross section inserted into the through hole of one of the components, a bolt with a washer that passes through the cylindrical rubber gasket, the component, and the flat rubber gasket. In the anti-vibration fastening structure consisting of a washer and nut attached to the bolt, the right angle part touching the circumference of the component through hole of the convex cross-section cylindrical rubber packing is rounded, or the end point from the outer periphery of the cylinder has a larger diameter. A cylindrical rubber gasket characterized in that it has a tapered part whose slope is in contact with a flange surface.
