To improve productivity of a suspension support which is made lighter.

An inner and an outer cylinders 1 and 2 are made of aluminum. A rubber elastic body 3 is vertically held by an upper and a lower inner circumferential flanges 6 and 7. The second inner circumferential flange 7 is molded in an opened shape when the outer cylinder 2 is forged. After the rubber elastic body 3 is inserted from an opening 11, a circumferential edge part of the opening is folded inward to be the second inner circumferential flange 7. The rubber elastic body is thus held compressed between both flanges to complete a product.
