Wide angle joint

A wide angle joint comprising:

• a pair of yoke shafts mounted on opposite sides thereof to transmit power from one side to an opposite side, each yoke shaft having a ball end portion provided on a first yoke part to which a spider universal joint is coupled;
• a plate having a large-diameter part formed in a middle thereof and protruding parts protruding from the large-diameter part in opposite axial directions while being reduced in a radially inward direction, wherein the protruding parts have insertion recesses into which the ball end portions of the yoke shafts are inserted, and the large-diameter part is formed to have different widths in different radial directions;
• and
• a pair of coupling yokes, each of which has a second yoke part connected with a respective one of the first yoke parts through the spider universal joint and a support recess into which the large-diameter part of the plate is inserted,
• wherein a radial gap is disposed between an outside surface of the large-diameter part and inner circumferential surfaces of the support recesses, and the large-diameter part comprises a large-width portion that forms a smallest portion of the radial gap together with the support recesses and a small-width portion that forms a largest portion of the radial gap together with the support recesses,
• the large-width portion includes large-width segments disposed symmetrically on radially opposite sides of the plate,
• the small-width portion includes small-width segments disposed symmetrically on radially opposite sides of the plate, and
• dampers formed of a resilient material are coupled to outer surfaces of connecting portions between the large-width portion and the small-width portion, and disposed between the outer surfaces of the connecting portions and inner circumferential surfaces of the support recesses of the coupling yokes.
