PURPOSE: To enable various kinds of parts feeding, by installing a slider block which is intermittently moved horizontally and by providing the slider block with a plurality of horizontal rows of parts housing grooves which extend at different levels and correspond to gates located at different levels.

CONSTITUTION: A plurality of parts feed units 1, in which different kinds of bolts (a) are stored, are installed at three levels in two columns. Parts outgoing passages 2 extend from the feed units 1. Gates 3 are provided at the downstream ends of the passages 2. A slider block 4, which is intermittently moved horizontally, is installed in front of the gates 3. The slider block 4 is provided with horizontal rows of parts housing grooves 5 which extend at three levels to correspond to the gates 3 at different levels. Each of the rows includes sixteen grooves, for example. The bolts sequentially put in the parts housing grooves 5 through the gate 3 are conducted to an inversion drum 17 through a pipe 6 and thereafter conveyed by air pressure to a prescribed place through a parts feed passage 16.
