Abstract:
To provide a feeding roll and a wire feeding device that are capable of attaching and detaching rolls using a simpler mechanism while regulating the relative rotation of the rolls.SOLUTION: A feeding roll A10 includes a gear 10, a boss 30, and a roll 20. The boss 30 has a rotation regulating part 39, a base part 31 fixed to the gear 10, and a support piece 32. The support piece 32 extends from the base 31 in an axis central direction N. The roll 20 has an inner peripheral surface 21 surrounding the boss 30 and a groove 24 recessed from the inner peripheral surface 21. At least a portion of the rotation regulating part 39 is accommodated in the groove 24. The support piece 32 has a beam part 321 and a claw part 322. The claw part 322 is located on the opposite side of the gear 10 with respect to the inner peripheral surface 21 in the axis central direction N. The beam part 321 bends in a radial direction r toward the side where an axis center n is located. The claw part 322 protrudes from the beam part 321 in the radial direction r on the side opposite to the side where the axis center n is located with respect to the inner peripheral surface 21.SELECTED DRAWING: Figure 1
