An automobile-motor driving device equipped with speed reducer which has improved supply of lubrication oil to inside of the rolling bearings without sacrificing the function of the bearings, to reduce deformation in the rolling bearing outer ring. A parallel shaft gear speed reducer provides an automobile-motor driving device equipped with speed reducer. The parallel shaft gear speed reducer includes a plurality of gear shafts having two ends supported via rolling bearings fitted into bearing fitting holes in a speed reducer casing which houses the parallel shaft gear speed reducer. A groove in an inner circumferential surface of the bearing fitting hole into which the rolling bearing is fitted communicates between a space that houses the speed reducer and an inside space of the bearing fitting hole, at a location not crossed by the line of action of a load acting upon the rolling bearing due to the meshing of the gears.
