摘要： PURPOSE:To prevent deformation of a member by the check pressure by fitting a rotation side member to hold the member outer periphery by a check claw, carrying out alignment and fixing the opposite surface of the member press- contact surface by a pin on a check face plate of a rotary head. CONSTITUTION:A pin hole of the member A is fitted on a pin 6 of setting material 5 to set it. The member A is held by the check claw 4 provided on the check face plate 2 on the tip of a rotation axis 1. The check claw 4 is fitted on a guide 3 of the check surface 2, the member A is held and centering is completed at the same time. Since the rotational force of a rotating check face plate 21 is transmitted to the member A via the pin 6, a slip is not generated between the check claw 4 and the member A and a flaw on the surface of the member A can be prevented. Since this is not a cap stopper type, the setup time can be reduced and productive efficiency is satisfactory.
