PURPOSE:To enhance the applicability of a walking type management machine provided with a belt type stepless speed change gear unit, for general purposes, by constituting the stepless speed change gear unit with a stationary rotary body and a movable type rotary body which is made in press-contact with the stationary rotary body and is movable radially of the latter to make it possible to steplessly or infinately change shift rotational speed. CONSTITUTION:By means of a manipulating element which is not shown, a driven disc 10 is moved radially of a drive disc 9 through a wire 14 and a shift lever 13. Accordingly, in accordance with a radial position from the center of the drive disc 9, the rotational speed of the driven disc 10 is shifted from zero, and is made to be possible to be transmitted to a transmission unit 16. With this arrangement the shift rotational speed may be infinately lowered. |
