  Any of the conventional muffler cutters using a belt may fall off due to vibration during use. That is, according to the structure of Patent Document 1, the end of the muffler body is mounted so as to be surrounded by the end of the muffler cutter, and the belt member is used by utilizing the plate body that protrudes from the end of the muffler cutter toward the muffler body. It is structured to wrap around the muffler body. That is, the muffler cutter is superposed on the upper surface of the muffler main body, but only the belt member fixes the muffler main body without the muffler cutter contacting the lower surface of the muffler main body. For this reason, all the loads generated by the vibration of the muffler cutter are transmitted to the plate body and the belt member.

  Moreover, since the muffler cutter does not contact the lower surface of the muffler main body and is locked to the muffler main body only by the upper surface of the muffler cutter, the muffler cutter itself has a structure that is extremely easy to shake. As a result, a large load is applied to the belt member, and when the load gradually expands the belt member, the muffler cutter connected only by the belt member falls off. Therefore, in Patent Document 1, in order to prevent the belt member from extending, a plurality of screws that penetrate the muffler cutter from the outside toward the belt member are arranged, and the outer surface of the belt member is strongly pressed by the tip of the screw. The draft is also disclosed. However, if it is attempted to prevent the belt from being stretched with screws, a large number of screws are required, which causes inconvenience that much labor is required for the mounting operation.

  Moreover, in patent document 2, it fixes with the belt member in the state which crimped | compressed the lower end part of the muffler main body which faced diagonally downward inside the muffler cutter. Therefore, when the muffler cutter vibrates up and down, the part in contact with the lower end of the muffler body becomes a fulcrum, and the coupling member and belt member provided on the upper part of the muffler cutter act as a point of action to concentrate a very large load. It has become. As a result, these large loads may cause the coupling member and the belt member to stretch or cut. If it does so, since the muffler cutter is connected only by the belt member also in this patent document 2, there is a possibility that the muffler cutter may fall off during traveling.

  Further, according to Patent Document 3, since the muffler cutter is suspended from the muffler body by a belt, the load of the muffler cutter and the load caused by vibration are all concentrated on the belt. In addition, since the belt is wound around the outer peripheral surface of the muffler body inclined downward, the muffler cutter may slide down along the inclined surface of the muffler body even when the belt is slightly extended.

  As described above, any of the conventional muffler cutters using the belt may drop off due to vibration during traveling. Such a drop off of the muffler cutter is extremely dangerous even on ordinary roads. However, if the muffler cutter is dropped off on a highway or the like, it may lead to a catastrophe.

  Therefore, the present invention was created to solve the above-described problems, and can reliably prevent an accident caused by the removal of the muffler cutter, and it also has a good appearance when worn and causes vibrations that cause the dropout.
