Further, it is possible to increase the number of steps. For example, as shown in the figure, between the small diameter step 15a and the large diameter step 15b, a medium diameter step 15c having an intermediate diameter between the small diameter step 15a and the large diameter step 15b is provided. Accordingly, a groove 16e can be added between the groove 16a and the groove 16b. In such a case, the operation pedal 12 is additionally set by the middle diameter step 15c at an intermediate step amount between the small diameter step 15a and the large diameter step 15b. Further, the steps and grooves can be increased as needed.
