摘要： According to the present invention, a nut is in a state of being received by nut receiving means. In this state, a ball-embedding nozzle is fitted into the nut so that a gap between the inner circumference of the nut and the outer circumference of the ball-embedding nozzle is uniformly formed around the entire circumference thereof. Balls are supplied into a screw groove of the nut via a ball supply path in the ball-embedding nozzle.
