Abstract

PURPOSE:To protect a ball joint assembly by separating a part for installing the protection boot of an inner ball joint from a part for installing a rack shaft side boot and installing those parts respectively. CONSTITUTION:An inner ball joint 10 is screwed and fixed to the end face of a rack shaft 2 via a bracket 8 having an installing part 6 for installing a rack shaft side boot 4. A boot holder 20 is installed on the outer periphery of the bracket 8 via an O-ring 18 for sealing. The boot holder 20 is formed in a cylindrical shape having a large diameter part 20a and a small diameter part 20b, and plural claws are formed at an equal interval in the circumferential direction on the end face on the large diameter part 20a side, while the end part 20d on the small diameter part 20b side is bent outward. After the boot holder 20 is installed on the bracket 8, a protection boot 22 for the ball joint is fixed to the holder 20, thereby, carrying out a boot assembling operation.
