摘要： PROBLEM TO BE SOLVED: To achieve a structure capable of sufficiently reducing a load on a starter motor for starting an engine without the occurrence of excessive sliding at each traction part, in a continuously variable transmission whose gear ratio can be changed infinitely.SOLUTION: After the engine is started, a controller gradually increases pressing force generated by a pressing device on condition that a shift lever is left in a non-travel state. Then, tilting angles of trunnions having supported respective power rollers are mutually synchronized. Thereafter, on the basis of a learning function, a step count for adjusting the gear ratio of a troidal type continuously variable transmission to a desired value is learned.

摘要： PROBLEM TO BE SOLVED: To materialize a structure capable of quickly carrying out gear shifting operation including switching between a low speed mode and a high speed mode while suppressing a sense of incongruity imparted to a driver to the minimum, when setting a manual mode in a continuous variable transmission in which a toroidal type transmission unit 1A is combined with a planetary gear type transmission unit 2A.
SOLUTION: This continuously variable transmission device retains a reduction gear ratio between an input shaft 7A and an output shaft 8A at values in a plurality of stages which are mutually different reduction gear ratios set in advance, and has a function to change the retained reduction gear ratios based on operation of the driver. Either one of the values in a plurality of stages regarding the reduction gear ratio is made to conform with the reduction gear ratio at the time when switching a low speed mode and a high speed mode. Since the moment when the driver shifts the gear concurs with the moment when a transmission shock occurs, a sense of incongruity is reduced.
