PROBLEM TO BE SOLVED: To quicken supply of tip parts by providing a going backward preven tion means preventing tip parts entering a parts entrance part from going back ward by air due to an agitation means. SOLUTION: On a part close to parts entrance part 8 of a parts transfer path 7 and the upper surface, a recessed part 10 is formed. A lock wall 11 is formed between the recessed part 10 and a parts temporary storage part 5. The lock wall 11 functions as a going backward prevention means for preventing tip parts 4 form going backward to the side of the parts temporary storage part 5. Tip parts 4 pushed up within the recessed part 10 by air do not go backward to the side of the parts temporary storage part 5 because a surface turning to the parts temporary storage part 5 is abutted on the lock surface 10a of the recessed part 10. When air supply is stopped, parts fall to the downstream of the parts transfer path 7. |
