PROBLEM TO BE SOLVED: To provide a laminated support 10 for suppressing the occurrence of crack in a portion of a rubber layer 1 or a rubber protecting layer 5 pasted to the edge of an end flange 4. SOLUTION: The face edge of the laminated support 10, adjacent to a laminate 3 of the end flange 4, is chamfered. This chamfered portion has a chamfering depth of 5 mm or greater in the direction of the thickness of the end flange, a thickness which is the thickness of the end flange minus the thickness of the rubber protecting layer, or smaller, and a chamfering angle of 32-72°with reference to the direction of a straight line perpendicular to the flange face of the end flange.
