Abstract
A stepless speed change device comprising an internally toothed ratchet formed in an inner circumference of a driving rotary body, a floating ring having an inner diameter smaller than a root diameter of teeth of the internally toothed ratchet and arranged in floating condition in side-by-side relation to the internally toothed ratchet, and a plurality of pawls whose distal ends engage the teeth of the internally toothed ratchet and inscribe the floating ring. Bottoms of the pawls are pivotally connectd to a driven rotary body rotatably provided on an eccentric cam assembly whose eccentricity is adjustable.
