Abstract:
A cross joint is provided which is adapted to prevent a shaft portion and rollers from being damaged when a bearing cup having the rollers on an inner periphery thereof is assembled to a cross shaft. The cross joint includes: a cross shaft 1 including four shaft portions 3; a closed-end cylindrical bearing cup 5; and plural needle rollers 6 having the first end portions thereof located on an opening side of the bearing cup 5 and arranged along the raceway surface of the bearing cup 5. An inner periphery of the bearing cup 5 includes a tapered surface portion. 11 increased in diameter toward the opening side. When the plural needle rollers 6 arranged along the inner periphery of the bearing cup 5 are fitted about the shaft portion 3, the tapered surface portion 11 allows the needle rollers 6 to incline as shifting the first end portions radially outwardly.
