PROBLEM TO BE SOLVED: To provide a wide range of transmission gear ratio by reducing the total of a required tilting angle allowance corresponding to torque shift. SOLUTION: A transmission control device, wherein a freely tilting power roller held between input and output discs is rotatably supported, includes a trunnion 4 rotatable around a shaft, and a transmission control valve 7 for controlling oil pressure to a hydraulic servo cylinder 1 to drive the trunnion 4 to the axial direction. In a precess cam 2 for transmitting the rotational movement of the trunnion 4 around the shaft to the transmission control valve 7 via a feedback link 5, collision preventive slopes 21, 21 are formed via bent portions 22, 23 on both sides of an normal control slope 20 and the bent portion 23 is formed in a recessed shape at the side of a greater transmission gear ratio. |
