摘要： PROBLEM TO BE SOLVED: To provide a draft device in a spinning machine, capable of easily determining whether a distance (off-set distance) between each top roller shaft center and corresponding bottom roller shaft center is set in an appropriate state corresponding to a kind of spun fiber.SOLUTION: A draft device in a spinning machine comprises a plurality of top rollers 17 to 19 that are supported with a frame 15 of a weighting arm 14 through top roller bases 20 to 22 respectively. The frame 15 has long holes 30a to 30c on an upper wall along the longitudinal direction. The top roller bases 20 to 22 are fixed to the frame 15 with bolts 23 that penetrate through the long holes 30a to 30c. Positioning pieces 31 to 33 that determine fixing positions of the top roller bases to the frame 15 comprise display parts (exhibiting different colors for each off-set distance Δ) that indicate fixing positions of top roller bases 20 to 22 to the frame 15 defined by defining parts 36 that determine positions of the top roller bases 20 to 22, and are fixed to the frame 15 so that each of the top roller bases 20 to 22 can be independently detached.
