Abstract
An engageable pawl member is provided so as to be swingable about a supporting shaft so that a pawl tip is movable along a moving path for a strapping band. The engageable pawl member is pulled forwardly in a swinging direction by a helical tension spring to push the pawl tip against the strapping band. The engageable pawl member shifts forwardly, following the movement of the strapping band in a feeding direction, and the strapping band is sandwiched and held between the engageable paw member and a holding guide. Then, the engageable pawl member follows the movement of the strapping band in a direction to pull back, and the engageable pawl member shifts backwardly so that the pawl tip moves in a direction out of the moving path for the strapping band.
