Abstract: PURPOSE: A variable exhaust pressure muffler utilizing a rotating blade is provided to improve reliability in the working performance and to extend the life span, by simplifying constitution. CONSTITUTION: A variable exhaust pressure muffler utilizing a rotating blade(10) has an axial hole(2) formed in the middle of an output end of a muffler case(1). Large holes(4) and small holes are alternately symmetrically formed to the outside of the axial hole. A guide groove(3) for guiding rotation of the rotating blade is spirally formed in the inner wall surface of the axial hole. The rotating blade is rotatably installed to the axial hole. The rotating blade has a blade(12) selectively opening the large holes or the small holes by linearly rotating according to the pressure of exhaust gas passing through the muffler case.
