PURPOSE: To supply a screw to a predetermined position stably and to make it possible to take it out stably by forming a bottom portion, at the conveying passage of a screw parts aggregate, which is inclined upward for pushing up a screw leg portion projected from the under surface of the aggregate from the lower part.

CONSTITUTION: A screw parts aggregate 9 in which screw parts are longitudinally taped at a predetermined distance is wound like a reel to be fitted to a supplying device. The head of the taping is reached to an escape portion 8 via a taping conveying passage 10 and screw parts are separated one by one to be supplied. Namely, screw parts 11 are supplied by a predetermined pitch to holes for feeding provided at the taping 9 at a predetermined distance, a screw leg portion projected from the bottom of the taping 9 does not obstruct feeding because an escape recess groove 13 is provided at the conveying passage 10. Since the bottom portion of the recess groove 13 is gradually risen from this side of the escape portion 8 and the screw leg portion is gradually pushed up upward during the pitch feed to the escape portion 8, vacuum drawing etc. become easy and stable supply and separated take-out become possible.
