Abstract: A ball joint 10 includes a ball seat 200, and the ball seat 200 includes a thermal caulking portion 221 for fixing a ball seat 200 to a housing 300. The ball seat 200 includes a concave portion 212 having an overhang portion 212b for withstanding a pullout load so as to prevent a ball portion 120 from coming off from the concave portion 212. The concave portion 212 of the ball seat 200 is formed of polyoxymethylene, and the overhang portion 212b and the thermal caulking portion 221 are formed of a resin, in which glass fiber is added to the polyoxymethylene, so as to be strengthened. Consequently, the pullout load can be increased, and the weight of the ball joint is maintained and the production cost is not greatly increased.

Abstract: A torque tuning method includes a high-frequency induction heating apparatus (20) that generates a magnetic field from a coil (24) by passing an alternating current (i) to the coil (24), which is arranged so as to be separated from an outer housing (11). By passing the current (i) having a predetermined frequency from the high-frequency induction heating apparatus (20) to the coil (24), a ball portion (10b) is induction-heated by a magnetic field generated from the coil (24) through which the current (i) flows, and after the ball portion (10b) has reached a temperature at which a ball seat (12) can be deformed by induction heating, the current (i) is stopped and the ball portion (10b) is cooled.

Abstract: A stabilizer device 1 includes a bar 100 having a portion 10a to be mounted to a vehicle body. A resin ring 40 is integrally formed to the bar 100 by a direct injection method, and a bush 30 made of rubber is provided around the periphery of the resin ring 40. The bush 30 is fixed to a member 50 of the vehicle body side by a bracket 20. Since the contact area of the resin ring 40 to the bar 100 is secured by using the axial direction length of the bush 30, the movement strength of the bush 30 in the axial direction can be improved even when there is size restriction. In the fixing construction of the stabilizer device, the movement of the bush to the bar can be sufficiently prevented even when the size restriction is severe.
