Abstract

An object of the present invention is to provide a yarn sending device (30, 40, 46, 50, 60) which is able to reduce the burden of maintenance and to achieve cost reduction.
A yarn sending device (30) includes: drive rollers (33) fixed to a drive shaft (31) which is rotationally driven; and driven rollers (34) which are rotated by making contact with circumferential surfaces of the drive rollers (33) and receiving a rotational force from the drive rollers (33). At a part of each driven roller (34) in an axial direction of the driven roller (34), a rotational force receiver (35) configured to make contact with a circumferential surface of one drive roller (33) and a yarn feeding unit (36) configured not to make contact with the circumferential surface of the drive roller (33) are formed. A yarn Y is wound onto the yarn feeding unit (36).
