SOLUTION: A circular recessed part 12A is formed on the end surface of a wire reel, and a projecting part 44A to be engaged with the recessed part 12A is formed on a turn table 44. The recessed part 12A and the projecting part 44A are formed so that their inner peripheral surfaces 44B are engaged with each other. The wire reel is cylindrically formed, and a rib 12R is formed on its inner peripheral surface 12C. |
