As is evident from FIGS. 4 and 5 , the expiratory resistor of the first embodiment has reflective symmetry between front and rear sides, and left and right sides; therefore FIGS. 2 and 3 represent the views of front and rear sides, and left and right sides, respectively. As is evident from FIGS. 10 and 11 , the expiratory resistor of the second embodiment has reflective symmetry between front and rear sides, and left and right sides; therefore FIGS. 8 and 9 represent the views of front and rear sides, and left and right sides, respectively. As is evident from FIGS. 16 and 17 , the expiratory resistor of the third embodiment has reflective symmetry between front and rear sides, and left and right sides; therefore FIGS. 14 and 15 represent the views of front and rear sides, and left and right sides, respectively. As is evident from FIGS. 22 and 23 , the expiratory resistor of the fourth embodiment has reflective symmetry between front and rear sides, and left and right sides; therefore FIGS. 20 and 21 represent the views of front and rear sides, and left and right sides, respectively.
