うなおそれはない。 When carried or not in use, the cylindrical cap 14 is rotated in the opposite direction so that the outer tube 3 and the cylindrical cap 14 come into contact with each other, eliminating a gap between them for the size of the notch. When the cylindrical cap 14 is rotated in the opposite direction in this state, the cylindrical cap 14 and the outer cylinder 3
Since the engagement element 6 of the core pipe cylindrical receiving part 7 is in contact with the end of the spiral path 5 of the cylindrical body 4 and the cylindrical body 4 does not rotate, the rod-shaped object holder 1
3 moves rearward along the spiral groove 15 of the cylindrical cap 14, and only the rod 11 protrudes from the rear end of the cylindrical body 4. Since there is no gap between the outer cylinder 3 and the cylindrical cap 14 when the rod-shaped object 11 is used, no knocking movement can occur, so even if a strong force is applied to the rod-shaped object 11, the rod-shaped object 11 will not sink. That's not it.
