Elastic piece of preventing elastic fatigue

The utility model discloses an elastic sheet of preventing elastic fatigue, which comprises a fixing part, spring parts and a butting part, wherein the two spring parts are respectively extended from both ends of the fixing part; the spring parts are alternately arranged fore and back and are extended and connected with both ends of the butting part so as to form an integral structure of the elastic sheet. Hence, the arrangement of the spring parts causes the elastic not to generate the deformation of deflection and shift after stressed; hence, the contact effect and the structural strength of the elastic sheet can be effectively enhanced.
