PURPOSE:To aim at speed up of the shooting action of a spoke by discharging the pressure air from an upper end of a spoke housing chamber to shoot the spoke from a nozzle. CONSTITUTION:A spoke S is housed in a spoke housing chamber, and when the pressure air is discharged from an upper part of the spoke chamber, the spoke S is moved to an opening end of a nozzle N, and the spoke S is shot from the nozzle N by the inertial force and the pressure air of this time to be inserted to a spoke hole of an annulus. At this stage, even if the spoke hole and the tip of the spoke S are dislocated from each other a little, since a spoke moving passage has a vibration space and the thrust is given to the spoke moving passage by compressive feeding with the pressure air, the vibration corresponding to the vibration space is generated in the spoke S, and the tip of the spoke S is inserted to the spoke hole. After completing the positioning of a hub, a move to the spoke shooting can be thereby performed quickly. |
