A stepless speed change gear that is small in size, light in weight, simple in construction, secure in operation. long in service life and capable of high-output speed changes. An input shaft crank (3) and an input side member (4) are mounted on an input shaft (1) and an output shaft (2) via a one-way clutch mechanism (100). respectively, and the respective members are coupled to each other by means of an input connecting rod (5) and an output connecting rod (6). Also, a speed-change link (7) is coupled to a junction point (B) of these links at one end thereof, and the other end thereof (Q) is allowed to move to any position within a certain range and to be fixed at that point. Also, the one-way clutch is a rolling bearing clutch. Variable speed change can securely be obtained with a simple mechanism. In a case where the rolling bearing clucth is used. high-output speed change is possible with the stepless speed change gear that is small in size and light in weight. |
