ABSTRACT:
A stepless speed change device comprises first ratchet rings arranged in plural rows side by side in an axial direction on an inner circumferential surface of a rotary member on an input side through one-way clutches interposed therebetween, and an eccentric cam assembly arranged on a center shaft. An eccentricity of the cam assembly is adjustable relative to the center shaft. The device further comprises first pawls in plural rows to engage ratchets provided in the ratchet rings and having bottoms pivotally connected to a carrier rotatably provided on the eccentric cam assembly. The bottoms of the pawls in one row are between the bottoms of the pawls in the other row. The device comprises second ratchet rings arranged in plural rows side by side in the axial direction on an inner circumferential surface of an annular portion formed integrally with the carrier through one-way clutches interposed therebetween, second pawls in plural rows to engage second ratchets provided in the second ratchet rings and having bottoms pivotally connected to a rotary member on an output side. The bottoms of the further pawls in one row are between said bottoms of the further pawls in the other row.
