摘要： Provided is a fastening band including a steel plate (111) plated with a plating layer (110) as a base material. The plating layer (110) has a self-repairing function of forming a protective film (112) on a plating peeling part with a component dissolved from the plating layer. The steel plate plated with a zinc-aluminum-magnesium alloy is used as the base material. The plating layer contains 4.0 mass % to 14.0 mass % of aluminum, 1.0 mass % to 10.0 mass % of magnesium, and the balance of zinc. The plating layer contains aluminum and magnesium in a total content of 15 mass % or less and zinc in a content of 85 mass % or more.

摘要： A constant velocity universal joint includes an outer joint member having an opening portion at one end thereof, and an inner joint member configured to transmit torque while allowing angular displacement with respect to the outer joint member through balls. End portions of a boot closing the opening portion of the outer joint member are fastened and fixed to a mounting part of the outer joint member and a mounting part of a shaft extending from the inner joint member. At a part of an outer peripheral surface of the shaft where at least an inner peripheral surface of the boot contacts when the shaft takes an operating angle with respect to the outer joint member, a sliding bearing is arranged to reduce abrasion due to friction caused by relative movement between the outer peripheral surface of the shaft and the inner peripheral surface of the boot.

摘要： A constant velocity universal joint has a large-diameter mounting portion fastened and fixed by a first fastening clamp onto a boot receiving portion of an outer joint member, and a small-diameter mounting portion fastened and fixed by a second fastening clamp onto a boot receiving portion of a shaft. A circumferential clamp groove to which the first fastening clamp is fitted is formed in an outer peripheral surface of the large-diameter mounting portion. A protruding portion is formed at a boot outer side end portion of an inner peripheral surface of the large-diameter mounting portion. A recessed portion to which the protruding portion is fitted is formed in the boot receiving portion being a cylindrical surface of the outer joint member. A projection is formed in the vicinity of a boot inner side of the recessed portion.
