INDUSTRIAL HYBRID ENGINE

Based on further ingenuity, it is possible to support a heavy and large electric motor on an engine body with sufficient strength while driving the electric motor with a belt without slipping, thereby providing a more streamlined industrial hybrid engine. The industrial hybrid engine is provided with an endless rotation band 9 wound around a drive pulley 6a of a crankshaft 6 and a motor pulley 8a of an electric motor 8 for motive power. The electric motor 8 is attached to an engine case k in a position-fixed state using one support bracket 22. The support bracket 22 includes first and second support portions 23 and 24 for attaching the electric motor 8, and attachment portions 25 positioned between the first and second support portions 23 and 24 for attaching the electric motor 8 to the engine case k.
