ABSTRACT:
A joint structure for bonding a ball portion and a shaft portion, with the ball including a mounting hole bored toward a center thereof. A corrugated surface for effecting the bonding is formed in an inner circumferential surface of the mounting hole. A shaft portion, of a softer material than the ball portion, is fitted into the mounting hole of the ball portion. An outer circumferential portion of the shaft portion is plastically locally deformed in the vicinity of a corrugated surface of the mounting hole with the ball portion and the shaft portion being are bonded to each other with a tightening force.
