Disclosed is a continuously variable transmission that expands the operating range over which belt-slip control is allowed, while maintaining the estimated precision of the belt-slip state. This reduces belt friction, thereby reducing the drive energy used. A belt (44) is wrapped around a primary pulley (42) and a secondary pulley (43), and the gear ratio is controlled by controlling a primary hydraulic pressure and a secondary hydraulic pressure. The disclosed belt-type continuously variable transmission for a vehicle is provided with a belt-slip control means (fig. 8) and a gear-ratio change-rate limitation means (step S23 in fig. 12). When a gear-ratio change rate is less than a given value, said gear-ratio change rate being the rate at which the gear ratio changes, the belt-slip control means controls the secondary hydraulic pressure on the basis of a phase difference ( ) between a vibration component due to oscillation in the actual gear ratio and a vibration component due to oscillation in the actual secondary hydraulic pressure. The gear-ratio change-rate limitation means uses prescribed acceleration limitation allowance conditions to determine whether or not the acceleration of the vehicle may be limited (steps S21, S22, and S26 in fig. 12), and if so, limits the gear-ratio change rate to less than the aforementioned given value.
