Title: WIRE FEEDING DEVICE
Abstract:
A wire feeding device comprising a feeding roll and a pressing roll. A weld wire is sandwiched between the feeding roll and the pressing roll and fed in a prescribed direction. The wire feeding device comprises: a pressing roll holder that supports the pressing roll; a pressing lever that applies pressing force to the pressing roll holder; and a support body that supports the feeding roll, the pressing roll holder, and the pressing lever. The pressing roll holder has a first end part and a second end part that are set apart from each other. The pressing roll holder is capable of rotating about a first axis along which the first end part extends. A force-receiving part that receives the pressing force from the pressing lever is provided to the second end part. The pressing lever is capable of rotating about a second axis. The pressing lever rotates between a pressing position at which the pressing force is applied to the pressing roll holder, and a pressing release position at which rotation of the pressing roll holder about the first axis is permitted.
