A gear shift control device for a continuously variable transmission of a vehicle is configured to steplessly and continuously change and output a rotation speed of an engine. The gear shift control device includes a gear shift control unit and a torque control command unit. The gear shift control unit is configured to implement a pseudo-stepped upshift control to change a gear shift ratio in steps when upshifting the continuously variable transmission. The torque control command unit is configured to output a torque reduction command so as to reduce an engine torque in conjunction with the pseudo-stepped upshift control so that reduction of the engine torque starts before a point in time when an actual gear shift ratio starts changing in response to an upshift command.
