<p>A belt type continuous reduction gear mechanism (Tm), in which a V-belt (42) is made to run under tension between drive and driven V-pulleys (40, 41) each equipped with a fixed pulley half (44, 57) and a movable pulley half (47, 59) made movable back and forth relative to the fixed half for adjusting and effective radius. The drive and driven V-pulleys are equipped with actuators (Hy1, Hy2) for moving the respectlve pulley halves thereof back and forth. There is interposed between the actuators a coaction mechanism (130) for effecting the coactions of the same.</p> |
