Thereafter, another pneumatic cylinder 114 moves back the work table 110 until the work table 110 reaches the work position.

When the work table 110 is placed in the work position, the Y-axis rail 154, the Z-axis rail 156, and the lift block (not shown) are inserted into the bolt feed hole 122 of the bolt feeder 120, 158 are moved, and then the suction device is operated to suck the bolt at the lower end of the driver 135. [

When the bolt is sucked to the lower end of the driver 135, the Y-axis rail 154, the Z-axis rail 156, and the lift block 158 move so that the bolt is positioned just above the ventilation member and the bolt hole of the housing. Then, the pneumatic cylinder 133 and the motor 134 of the bolt fastener 130 are operated, and at the same time, the adsorber is stopped, and in this process, the bolt is fastened to the bolt hole.
