ABSTRACT:
A magazine device of an air nailer is disclosed. A support shaft for supporting a coil nail is formed by fitting concentrically a guide post having an outer diameter corresponding to the winding diameter of the coil nail, an adjust post inside the guide post and a tension post inside the adjust post so that the guide post outside the adjust post, that is fixed to the bottom of a case cover, is rotatable with respect to the adjust post and the tension post inside the adjust post is also rotatable with respect to the latter. While the support shaft is under the fitting stage, a guide pin is inserted through the support shaft in its radial direction. The adjust post is moved in the circumferential direction while the guide pin is engaged with several receiving stages having different heights and along with this movement, the guide post as well as a nail bracket are rotated and can extend or retract with respect to the adjust post. The tension post permits the movement of the guide pin in the axial direction of the support shaft. A tension spring is interposed between the tension post and the case cover in such a manner that the rewinding force acts upon the tension post, and always engages the guide pin with the receiving stage of a guide window hole.
