Binding machine

A binding machine comprising:

• a wire feeding unit configured to feed a wire;
• a curl guide configured to curl the wire fed by the wire feeding unit around an object to be bound;
• a binding unit including a twisting shaft provided to be rotatable around a predetermined axis, a gripping part provided at one end side of the twisting shaft and a drive unit provided to the other end side of the twisting shaft, wherein the gripping part is configured to grip the wire curled by the curl guide and the twisting shaft is configured to twist the gripped wire so as to bind the object;
• a control unit configured to control an operation of the drive unit;
• and
• a binding machine main body configured to accommodate therein the binding unit and the control unit,
• wherein when an inside of the binding machine main body is divided into two by a virtual plane perpendicular to or substantially perpendicular to the axis so as to be partitioned into a first space in which the gripping part is accommodated and a second space in which the drive unit is accommodated, the control unit is arranged in the second space in which the drive unit is accommodated.
