Design registration No. 1069774 (front view, left side view)

  However, recently, as shown in FIG. 25, there is an exhaust muffler 1 of the vehicle 2 that faces obliquely downward. If the conventional muffler cutter is attached to such an exhaust muffler 1, the muffler There was a drawback that the exhaust port of the cutter turned downward, and the appearance of the muffler cutter as viewed from the rear became worse.

  The present invention eliminates the above-mentioned drawbacks.

  The muffler cutter for a vehicle according to the present invention includes a muffler cutter main body and a coupling member that couples the muffler cutter main body to an exhaust muffler of the vehicle so as to be tiltable with respect to an axis thereof.

  A muffler cutter for a vehicle according to the present invention includes a muffler cutter body and a coupling member that couples the muffler cutter body to an exhaust muffler of the vehicle so as to be rotatable about its axis.

  The coupling member includes a belt member fastened to the outer periphery of the exhaust muffler.

  The coupling member is located in a notch provided in the muffler cutter body.

  The coupling member includes a plate member having an outer surface in contact with an inner surface of the belt member, and a movement latching means for the belt member.

  The movement latching means is plural.

  The coupling member includes a first plate member coupled to the muffler cutter body, a second plate member coupled to the first plate member, and the belt provided on the first and second members. It comprises an outer surface that is in contact with the inner surface of the member, and a movement latching means for the belt member.

  The plate member is provided in the muffler cutter main body so as to be tiltable in the left-right direction with respect to the axis thereof.

  The belt member moving latching means is provided movably with respect to the plate member.
