To provide a manufacturing method for a suspension support capable of enhancing productivity of the lightweight suspension support.

Using an outer cylinder 2 integrally molded by aluminum to a shape provided with a cylinder part 21 capable of storing a vibration-proof base body 3 comprising a rubber-like elastic body, an inner peripheral flange part 22 provided at an axial one side of the cylinder part 21, and an opening 23 formed so as to receive the vibration-proof base body 3 at the axial other side of the cylinder part 21, after the vibration-proof base body 3 integrated with an inner cylinder 1 is stored in the cylinder part 21 through the opening 23, a plate member 4 is stored in the opening 23 while the vibration-proof base body 3 stored in the cylinder part 21 is clamped by the inner peripheral flange part 22 and the plate member 4 in an axial direction. A peripheral edge of the opening 23 is inwardly calked to mount/fix the plate member 4 to the cylinder part 21.
