To enable an accurate yarn-feeding motion to be performed and facilitate the change of yarn-feeding motion accompanying the shift of the winding direction.

This weft length-measuring and storing device is provided with a weft yarn-feeding mechanism in which the weft yarn wound on a length- measuring dram is moved by plural feeding pieces via a feeding piece bush attached to the rotary shaft. The feeding piece bush comprises a base member consisting of a single member protruding from the end surface of the rotary shaft and a setting member engaged with the outside of the base member. The base member is attached to the rotary shaft in either state out of inclination and eccentricity against the rotary shaft, the peripheral surface of the setting member is in the other state out of the inclination and eccentricity against the base member, and the setting member can be attached in a different phase against the base member.
