PROBLEM TO BE SOLVED: To perform the operation of inserting a butterfly rod smoothly by arranging a slider in an inclined state to the box body of an opening, separating, fitting, and inserting device. SOLUTION: The upper surface of a box body 1 is formed into an inclined slope part 16, and the slope part 16 is formed into a downgrade slope from a side wall 9a of a box-rod insertion hole 4 toward a side wall 9b of a butterfly rod insertion hole 5. When the rear open side S' of a slider S is brought into contact with the box body 1 at the time of opening, separating, fitting, and inserting operations to insert a butterfly rod 3 into the box body 1 in which a box rod 2 is fitted, inserted, and fixed to the box-rod insertion hole 4 of the box body 1, the slider S is inclined to the box body 1. As the butterfly rod 3 is inserted into the butterfly insertion hole 5 of the box body 1 from diagonally above the box body 1 in this slide fastener in comparison with that the butterfly rod 3 was inserted into the butterfly-insertion hole 5 from immediately above the box body 1 before, it is possible to perform operations extremely smoothly and simply. |
