The packings are compressed to protrude the rubber elastic piece 1 from the edges of the reinforcing steel sheets 2. The protruded portions are cutoff. The compressive force to the packings is removed. Since arc-shaped recesses 6 are provided on the lateral face of the elastic piece 1, this piece is not deformed and protruded from the reinforcing steel sheets even if a vertical and a horizontal forces act to the rubber elastic piece. This results in reducing stress concentration due to protrusion of the rubber elastic piece and improving its durability.
