Claim:
1. A container refrigeration device with a refrigerant circuit including a compressor, a condenser, an expansion mechanism, and an evaporator which are sequentially connected together, and with an inside fan configured to blow inner air having exchanged heat in the evaporator of the refrigerant circuit to an inside of a container, a rotation speed of the inside fan being variable, the container refrigeration device comprising: a fan controller which reduces the rotation speed of the inside fan when a temperature inside the container has continuously remained within a predetermined temperature range set relative to a target temperature; and a rotation speed controller which, in response to the reduction of the rotation speed of the inside fan by the fan controller, reduces an operational rotation speed N of the compressor such that the temperature inside the container becomes equal to the target temperature.
