Background technology A CVT has a belt that transmits torque between an input sheave and an output sheave, and the radius of the belt on the input sheave and the output sheave is controlled by the pressing force from the input sheave and the output sheave. As a result, the gear ratio (=reduction ratio) is continuously controlled. In order to move the vehicle forward, backward, or stop, a planetary gear mechanism must be installed in series with the CVT in the engine's power transmission path, but in conventional continuously variable transmissions for automobiles, the planetary gear mechanism is It is located on the side.

Therefore, the direction of movement of the belt is opposite during forward movement and reverse movement, and when the belt is in neutral position, rotation of the input and output side sheaves stops, and the friction of the belt against the tapered surface of the sheave increases. It is difficult to shift the CVT. The CVT shift when in neutral is CV
It is very important to set T to the maximum reduction ratio immediately before starting to prepare for the next start, and a decrease in the direction of belt movement will cause a decrease in belt durability. Furthermore, it is advantageous that the reduction ratio of the planetary gear mechanism during forward movement and during reverse movement is the same in order to match the maximum climbing capacity during forward movement and during reverse movement.

During forward movement, the clutch 52 is in the engaged state and the brake 54 is in the released state. As a result, sun gear 42 and carrier 50 rotate integrally, and the rotation of output shaft 18 is transmitted to shaft 56 in the same direction at a reduction ratio of 1.
