。 This is a rotational speed control device for a cooling fan that is rotatably driven by a hydraulic motor, and includes a water temperature sensor that detects the temperature of the cooling water of the internal combustion engine, and a refrigerant pressure sensor that detects the opening and closing of the air conditioner switch and the refrigerant pressure of the air conditioner. In response to at least one of them and the cooling water temperature detected by the water temperature sensor, the flow rate of the working fluid supplied to the hydraulic motor is increased in accordance with the rise in the cooling water temperature, and the air conditioner switch is closed. or when the refrigerant pressure detected by the refrigerant pressure sensor is high, the fluid is supplied to the hydraulic motor compared to when the air conditioner switch is open or when the refrigerant pressure detected by the refrigerant pressure sensor is low. A rotation speed control device for a cooling fan, comprising: a flow rate control device that increases the flow rate of the working liquid relative to the temperature of the cooling water.
