A binding machine comprising: a wire feeding unit configured to feed a wire to be wound on an object to be bound; a binding unit configured to twist the wire wound on the object to be bound; a curl guide configured to curl the wire being fed by the wire feeding unit, wherein the curl guide comprises: a first guide plate, a second guide plate, and a third guide plate located between the first and second guide plates; and an inductive guide (S1A) configured to guide the wire curled by the curl guide toward the binding unit; whereby the binding machine further comprises: a retraction guide part (54DL, 54DR), the retraction guide part (54DL, 54DR) being configured to retract the wire on a downstream side of the binding unit with respect to a feeding direction of the wire that is fed by the wire feeding unit in a direction of curling the wire by the curl guide, so that in a state in which there is an obstacle in a position in which it blocks a feeding path of the wire, the wire coming into contact with the obstacle is retracted through the retraction guide part (54DL, 54DR), wherein the retraction guide part (54DL, 54DR) is provided on an axially outer side of a loop to be formed by the wire, and the retraction guide part (54DL, 54DR) is configured by providing the third guide plate as protruding further than the first and second guide plates (50L, 50R) toward a downstream side with respect to the feeding direction and by the resulting space on both sides of the third guide plate with regard to the first and second guide plates, through which the wire can pass toward the axially outer sides of the loop to be formed by the wire, with respect to the feeding of the wire in the forward direction. a wire feeding unit configured to feed a wire to be wound on an object to be bound; a binding unit configured to twist the wire wound on the object to be bound; a curl guide configured to curl the wire being fed by the wire feeding unit, wherein the curl guide comprises: a first guide plate, a second guide plate, and a third guide plate located between the first and second guide plates; and an inductive guide (S1A) configured to guide the wire curled by the curl guide toward the binding unit; whereby the binding machine further comprises: a retraction guide part (54DL, 54DR), the retraction guide part (54DL, 54DR) being configured to retract the wire on a downstream side of the binding unit with respect to a feeding direction of the wire that is fed by the wire feeding unit in a direction of curling the wire by the curl guide, so that in a state in which there is an obstacle in a position in which it blocks a feeding path of the wire, the wire coming into contact with the obstacle is retracted through the retraction guide part (54DL, 54DR), wherein the retraction guide part (54DL, 54DR) is provided on an axially outer side of a loop to be formed by the wire, and the retraction guide part (54DL, 54DR) is configured by providing the third guide plate as protruding further than the first and second guide plates (50L, 50R) toward a downstream side with respect to the feeding direction and by the resulting space on both sides of the third guide plate with regard to the first and second guide plates, through which the wire can pass toward the axially outer sides of the loop to be formed by the wire, with respect to the feeding of the wire in the forward direction. a retraction guide part (54DL, 54DR), the retraction guide part (54DL, 54DR) being configured to retract the wire on a downstream side of the binding unit with respect to a feeding direction of the wire that is fed by the wire feeding unit in a direction of curling the wire by the curl guide, so that in a state in which there is an obstacle in a position in which it blocks a feeding path of the wire, the wire coming into contact with the obstacle is retracted through the retraction guide part (54DL, 54DR), wherein the retraction guide part (54DL, 54DR) is provided on an axially outer side of a loop to be formed by the wire, and the retraction guide part (54DL, 54DR) is configured by providing the third guide plate as protruding further than the first and second guide plates (50L, 50R) toward a downstream side with respect to the feeding direction and by the resulting space on both sides of the third guide plate with regard to the first and second guide plates, through which the wire can pass toward the axially outer sides of the loop to be formed by the wire, with respect to the feeding of the wire in the forward direction.
