PROBLEM TO BE SOLVED: To suppress abnormal wear on a specified gear tooth of a gear for changing the eccentricity of an eccentric member in a vehicular power transmission device including a crank-type continuously variable transmission.SOLUTION: The teeth number of a ring gear 19b is set to a value that is different by the integral multiple of the teeth number of a pinion 17. When a shift range detected by a shift range detection means is a non-running range, a change gear ratio control means U drives a shifting actuator 23 and rotates an eccentric disc 19 360° with respect to an eccentric cam 18. As a result, the gear teeth of the pinion 17 meshing with the gear teeth of the ring gear 19b can differ between before and after the rotation, which can prevent a gear tooth of a specified gear "a" of the pinion 17 from wearing. The eccentric disc 19 rotates 360° when the shift range is the non-running range and a vehicle is stopped, and there is therefore no problem even when a change gear ratio of a continuously variable transmission temporarily changes during the rotation. |
