PROBLEM TO BE SOLVED: To enable a vehicle equipped with a crank type stepless speed change device to make an evacuation travel when unable to travel by a driving source for traveling.SOLUTION: A crank type stepless speed change device T is so constituted that an input-side fulcrum 19 which rotates eccentrically and integrally with an input shaft 12 and an output-side fulcrum provided to an outer member 38 of a one-way clutch 36 supported at an outer periphery of an output shaft 13 are connected to each other through a connecting rod 33, so when the input shaft 12 rotates by an engine E and the connecting rod 33 moves reciprocally, the one-way clutch 36 intermittently engages and the output shaft 13 intermittently rotates so as to transmit driving power. When an electric motor of a speed change actuator 23 is driven while a travel by a driving source E for traveling ends in failure, a speed change shaft 15 rotates relatively to the input shaft 12 and the eccentricity of the input-side fulcrum 19 is changed, so the connecting rod 33 connected to the input-side fulcrum 19 is driven and the output shaft 13 rotates to enables the vehicle to make an evacuation travel. |
