Movement-converting device, in particular a speed reducer, comprising a first stage comprising two movable members (50, 60), at least one of which is coupled functionally to a shaft (74) generating a rotational movement; a second stage comprising at least one set of two pulleys (54, 54) [sic] linked in rotation, and interacting respectively with transmission means, for example two endless driving belts (52, 64) which interact with the movable members of the first stage; and a movable support (26) which supports, freely in rotation, the two pulleys of the second stage, and the displacement of which, over an imposed trajectory, generates a second movement, the first movement being a rapid movement and the second movement being a slow movement. |
