PROBLEM TO BE SOLVED: To inexpensively provide an engine-driven heat pump device of high durability while simplifying its constitution, though the rated operation of an engine is performed corresponding to the variation of the air conditioning load. SOLUTION: A generator is interlocked and connected to the engine through a clutch for power generation, and a compressor is interlocked and connected to the engine through a clutch for air conditioning. The air conditioning load is operated by an air conditioning load operating means on the basis of an indoor temperature measured by an indoor temperature sensor, a target temperature set by an air conditioning temperature setting device, and an outside air temperature measured by an outside air temperature sensor, a ratio of air conditioning time for operating the compressor and power generation time for operating the generator is calculated on the basis of the air conditioning load by a ratio calculating means, and the switching of the clutch for power generation and the clutch for air conditioning is controlled by a clutch control means to control the ratio of the air conditioning time and the power generation time within a set time, on the basis of the ratio calculated by the ratio calculating means.
