To enable the 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 pleural feeding pieces via a feeding piece bush engaged with the rotary shaft. The feeding piece bush comprises an inclination member engaged with the rotary shaft in an inclined state and an eccentric member whose peripheral surface is eccentric to the inner circumference surface, and which is engaged with the peripheral surface of the inclination member and can be attached in a different phase against the inclination member.
