PROBLEM TO BE SOLVED: To provide a repair structure of an existing elastic support device modified and repaired to a functional discrete type elastic support device preventing fluctuation in a normal time of an upper structure due to live load such as wheel load on an existing base plate, and to provide a repair construction method. SOLUTION: A steel lower support member 2 having a pair of side support members 5 is fixedly placed on the base plate 1 of the existing elastic support device, a shearing deformation restrictive member 8 having a vertically penetrated through hole for containing a slide type load support elastic support 12 is fixed to the upper part of the steel lower support member 2, the slide type load supporting elastic supporter 12 is installed in the shearing deformation restrictive member 8 so that the elastic layer 15 in the slide type load supporting elastic support 12 is constituted so as not to deform in the shearing force, and a horizontal buffer 19 is arranged on the upper face of the side of the steel lower support member 2 and the other side of the horizontal buffer 19 is fixed to the main girder 47.
