In this case, the parts automatic supply device 10 is mounted on the work floor 12, and the parts automatic supply device 10 is mounted on the upper walls 14a and 14b horizontally suspended above the floor surface 12. A parts distribution unit W16 is provided that arranges and delivers a predetermined number of parts, such as valve guides (described later), at equal intervals.

Therefore, first, the parts distribution device 16 will be explained. That is, pillars 18a, 20a and 18b120b having different heights are erected on the upper walls 14a and 14b, respectively, and parts feeders 22a and 248 are installed on the pillar 18a having a large height and the pillar 20H having a small height. is established,
