1. A binding machine comprising:
a main body;
a wire feeding unit configured to feed a wire;
a curl forming unit comprising a curl guide and configured to form a path along which the wire fed by the wire feeding unit is to be wound around a to-be-bound object;
a cutting unit comprising a cutting blade and configured to cut the wire wound on the to-be-bound object; and
a binding unit comprising a wire engaging body, the binding unit positioned in the main body and configured to twist the wire wound on the to-be-bound object and cut by the cutting unit,
wherein the wire feeding unit comprises a pair of feeding members configured to sandwich the wire and to feed the wire by a rotating operation,
wherein an amount of contact between one feeding member of the pair of feeding members and the wire is switched in accordance with a feeding direction of the wire,
wherein, as compared to the amount of contact between the one feeding member and the wire in an operation of feeding the wire in one direction and winding the wire around the to-be-bound object, the amount of contact between the one feeding member and the wire in an operation of feeding the wire in other direction, which is opposite to the one direction, and winding the wire on the to-be-bound object is made larger,
wherein the one direction is a direction extending from the pair of feeding members toward the curl guide, and
wherein a feeding path of the wire that is fed by the wire feeding unit is bent along the one feeding member on a downstream side, in the one direction, of a location where the pair of feeding members face each other with respect to a feeding direction of the wire.
