The utility model pertains to the technical field of couplings, and discloses an end cover used for a spider type universal coupling. An end cover body (1) is circular and is uniformly provided with a plurality of screw holes (5) along the circumference; one side of the end cover body is provided with a flat cylinder (2); the diameter of the cylinder is equal to that of the circular end cover body; two arc surfaces (3) are respectively and symmetrically arranged from the top surface (4) to two sides of the cylinder; and bolt holes (6) are vertically arranged on the top surface of the cylinder. The end cover used for the spider type universal coupling can effectively utilize the space of a flange jaw, leads the end cover structure to be more solid, improves the strength, and increases the born axial impact load.
