1. A binding machine, comprising:
a wire feeding portion which feeds a wire;
a cutting portion which is provided on a downstream side of the wire feeding portion along a feeding direction of the wire fed by the wire feeding portion and cuts the wire;
a first abutment portion which is provided between the wire feeding portion and the cutting portion and on a first side of a feeding path of the wire and capable of abutting on the wire from the first side; and
a guide portion which is provided on a downstream side of the cutting portion and on a second side opposite to the first side with respect to the feeding path of the wire, includes a second abutment portion capable of abutting on the wire from the second side, and regulates an advancing direction of the wire and causes the wire to curl by making the second abutment portion abut on the wire in a state where the wire abuts on the first abutment portion, wherein
the cutting portion includes:
a fixed blade in which a first wire passage through which the wire passes is formed; and
a movable blade in which a second wire passage is formed and which slides on an outer peripheral surface of the fixed blade and cuts the wire, the second wire passage being configured by an opening through which the wire passes,
the movable blade configured to move between a standby position where the first wire passage and the second wire passage communicate with each other and a movement finish position where the first wire passage and the second wire passage do not communicate with each other by sliding on the outer peripheral surface of the fixed blade,
the second wire passage includes a guiding portion for guiding the wire after cutting in a movement when the movable blade moves from the movement finish position to the standby position, the guiding portion including a recess configured such that a dimension, in the moving direction of the movable blade, of a downstream side end of the opening, in the feeding direction of the wire, is greater than a dimension of an upstream side end of the opening, in the feeding direction of the wire, the recess being configured to hold and contact the wire, and
the guiding portion is located on the second side and is configured to protrude in a direction of the guide portion and blocks a portion between the movable blade and the guide portion in a non-wire-passing-through manner when the movable blade moves to the standby position.
