Fixing device for a rotating machine on a vehicle motor

The device has a guide pin type fixation unit (2) and a lug type fixation unit (3), where the units project outside an outer periphery of a case (1a) of a rotating machine (1). The units are placed perpendicular to each other in upper and lower parts of the case. The units have openings for cooperating with a support (7) through a clamping unit to distribute forces due to integration of the machine on the support of an engine.
