Abstract: When a nylon cord is used as a cutter for mowing weeds and lawns, extraction and replacement of the nylon cord are facilitated. A reel (5) having a cylindrical member (6) is inserted on a bearing (4) of a case body (1). A through hole (12) extends through the cylindrical member (6) to be perpendicular to the axis of rotation of the cylindrical member (6) outside the inner diameter portion of the cylindrical member (6). A guide member (14) having pawls (13) and a pin press (16) having pawl presses (15) are provided in the cylindrical member (6). End portions (15b) of the pawl presses (15) corresponding to trough portions (13b) are inclined with respect to the upper surface of a support flange (11) at an appropriate acute angle. A main shaft (20) is inserted in the bearing (4). A stopper pin (22) to engage with the guide member (14) is provided in the main shaft (20).
