PURPOSE: To provide a device for aligning thin cylindrical work, which can fit thin cylindrical works out of an aligning bar without pinching them and which has the simple structure and which can easily correspond to a change of position of the aligning bar.

CONSTITUTION: A stopper part 14 and a work outlet 16 are provided in the lower part of an inclined gutter 12. A bottom wall 12b of the inclined gutter 12 facing to the outlet 16 is inclined at an angle θ toward the outlet 16 side, and the upper end of an aligning bar 4, which can be inserted into a center hole of a work 2, is positioned in the side and lower part of the outlet 16. A work 2 rotated downward for movement inside of the inclined gutter 12 abuts on the stopper part 14, and thereafter, the work 2 is made to fall down by the inclination of the bottom wall 12b, and falls from the outlet 16. On the way of this fall, the work 2 is fitted out of the aligning bar 4 for alignment.
