Abstract
A speed change control system is equipped with a feedback mechanism which feeds back the gyration angle of a power roller and the axial displacement of the power roller, to a speed change control valve (100) via a speed change link (12). The feedback mechanism comprises a cam plate (2) which outputs a feedback amount according to the gyration angle of the power roller, an L-shaped link (7) which outputs a feedback amount according to the axial displacement of the power roller, and a feedback link (3) connected to the cam plate (2) and L-shaped link (7), and connected to the speed change link (12). The feedback gain of the feedback amount according to the axial displacement of the power roller due to the L-shaped link (7), is varied according to the gyration angle of the power roller.
