よりなることを特徴とする。To achieve this object, a method of manufacturing a universal joint yoke according to the present invention has a race hole inner diameter for accommodating a cross shaft head.
Arranging individual steel sleeves in a mold as cores that penetrate through the yoke holes of a pair of yoke legs facing each other, and casting a universal joint yoke made of cast steel around the steel sleeves as cores. Then
It is characterized in that it comprises a step of casting a part of the steel sleeve into the yoke hole of the yoke leg, and a step of cutting off a part other than the part existing in the yoke hole of the yoke leg of the steel sleeve.

ことができる。According to the present invention, since the steel sleeve is embedded over the entire inner surface of the yoke hole of the cast steel yoke, after inserting the cross shaft head into the yoke hole, the periphery of the steel sleeve is closed. The cross shaft head can be fixed by continuously or discretely striking and caulking.

サルジョイントの十字軸のヘッド（ベアリングケース）
を挿入するレース孔に対応する形状にする。FIG. 1 shows an embodiment of three types of steel sleeves 1 used as cores for the yoke holes of a casting yoke. The inner surface of this steel sleeve 1 is a cross joint head (bearing case) of a universal joint.
Make the shape corresponding to the race hole to insert.
