PROBLEM TO BE SOLVED: To reduce the number of components and working hours during manufacturing time and cut down cost in an attempt to drain condensed water or penetrated water favorably in an outdoor machine unit of an engine-driven heat pump device. SOLUTION: In an outdoor machine unit of an engine-driven heat pump device, a groove-shaped drain recessed part 81 is integrally provided on the top 2a of a frame 2 of a power unit housing case. The top 2a is formed so that water deposited on the top may be collected in the recessed part 81. The drain recessed part 81 is formed slantingly so that it may reach the rear surface, lowering the bottom of the groove as it approaches the rear side, thereby discharging water which flows in the drain recessed part 81 outside from the side of the rear surface. |
