WIRE FEEDING DEVICE

The object is to adjust a moving amount of a wire to an appropriate amount and feed the wire with appropriate force. A wire feeding device 1 feeding a guide wire GW includes a grip portion 10 that is able to grip the guide wire GW and move in the distal end direction, a hammer 15 that is arranged on the proximal end side of the grip portion 10, and is movable in an axial direction of the guide wire GW and is able to come into contact with and separate from the grip portion 10, a push spring 16 that is able to energize the hammer 15 toward the distal end direction, a slider 20 that deforms the push spring 16 and increases energizing force on the hammer 15 toward the distal end direction, and a protruding portion 5D that releases a deformed state of the push spring 16 with the energizing force increased by the slider 20. The guide wire GW gripped by the grip portion 10 is fed toward the distal end direction by causing the hammer 15 to hit the grip portion 10 by the energizing force of the push spring 16 whose deformed state is released by the protruding portion 5D and moving the grip portion 10 toward the distal end direction.
