Abstract
A yoke for universal joint includes a base portion and a pair of opposed side walls and is connected to one end of a rotating shaft having two planes parallel to each other. One end of the rotating shaft is inserted between the opposed side walls such that both planes oppose the respective opposed side walls and the lower surface is abutted on the base portion. Then, a fastening portion of the opposed side walls in the upper portions thereof is fastened by a bolt such that the rotating shaft is interposed and fixed. On the inner surfaces of the opposed side walls, the concave portion is formed under the fastening portion. The concave portion is pushed against the outer peripheral square portion of the rotating shaft in both sides of the fastening portion in the axial direction of the rotating shaft.
