The guide rail 76 is satisfied if it is installed in the section between the inclined chute 43 and the discharge chute 77 in which the bolt 3 and the retainer 2 are located, without having to install the entire section of the turntables 33a and 33b. do.

The insertion grooves 70 and 71 vary in size in consideration of the outer diameters of the bolt 3 and the retainer 2. That is, in view of the fact that the outer diameter of the retainer 2 is larger than the outer diameter of the bolt 3, the size of the insertion groove 71 of the lower turntable 33b is larger than the size of the insertion groove 70 of the upper turntable 33a. However, the center line of the insertion grooves 70 and 71 is positioned on the vertical virtual line O, so that the bolt 3 is located at the top and the retainer 2 is directly below the bolt 3 as shown in FIGS. 9 and 11. It is moved in the state which can be temporarily assembled while being located.

Since the turntable 33 rotates in the counterclockwise direction, as shown in FIG. 8, the bolt 3 is attached to the upper turntable in a state where the retainer 2 is first inserted into the insertion groove 71 of the lower turntable 33b. It is later inserted into the insertion groove 70 of 33a).

The turntables 33a and 33b have a flat portion 9 formed at the bottom of the head 4 of the bolt 3 and a flat portion 15 formed at the bottom of the flange 12 of the retainer 2, respectively. It is preferable to construct a planar shape so that it can contact.
