PURPOSE:To eliminate skill work and to aim at the reduction of a working time, the stability of quality, improvement of manufacturing efficiency and the prevention of vibration noise by measuring bending torque to pressurize and adjust the torque by means of predetermined pressurizing force to be reference value in case of less than predetermined value. CONSTITUTION:An input shaft 51 connected to the yoke 12 of a Hook's joint 10 is driven by a torque actuator 21 via a torque sensor 22 and the signal of a strain gauge 221 is amplified by a torque amplifier 23 to be input to a calculating control means 30. The calculating control means 30 judges an input signal through bending torque to output it to a pressurizing means 40 in case of less than reference value. The pressurizing control means 40 pressurizes a caulking portion 15 by means of a pressurizing actuator 43 in response to the signal of the calculating control means 30. Accordingly, skill work is eliminated to eliminate the irregularity of working time, quality is stabilized, manufacturing efficiency is improved and vibration noise can be reduced. |
