Claims

[Scope of utility model registration request]

A plurality of mutually parallel rotating shafts arranged around the center of the rubber band binding device, an arm part and a toe part form an L shape, and the base end of the arm part is perpendicular to the rotating shaft at the tip of the rotating shaft. an expansion nail for expanding a rubber band fixed to the rubber band, and the expansion nail is rotated together with the rotating shaft so that the tip portion of the expansion nail rotates outward from the center of the rubber band binding device, and vice versa. In a rubber band binding device equipped with a rotary drive device that drives reciprocating rotation, a removal member for removing the rubber band is provided behind the arm portion of the expansion claw, and the removal member includes a rubber band binding device that is attached to both sides of the toe portion of the expansion claw in an expanded state. 1. A rubber band binding device, characterized in that a protruding portion is formed at the tip of the expanding claw, and the rubber band hung in an expanded state on the tip of the expanding claw is pushed out by the protruding portions on both sides of the tip.
