ことを特徴とする無段変速機の変速指令弁。[Claim for Utility Model Registration] A rack provided on the spool of the speed change command valve is engaged with a pinion gear rotationally driven by a speed change motor, and the speed change ratio is adjusted according to the axial position of this spool. In the shift command valve of a continuously variable transmission, a stopper pin attached to the valve body protrudes into the valve hole of the shift command valve, and when the spool moves to a predetermined position in the axial direction, it contacts the stopper pin and stops. The continuously variable transmission is characterized in that the spool is provided with an axial stop portion that allows the spool to rotate, and that the spool is provided with a rotational direction stop portion that comes into contact with a stopper pin and is stopped when the spool attempts to rotate. Speed change command valve.
