An object of the present invention is to reduce deformation in the rolling bearing outer ring, thereby providing 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. 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 their two ends supported via rolling bearings (34b) fitted into bearing fitting holes (32b) formed in a speed reducer casing (20bL) which houses the parallel shaft gear speed reducer. A groove (45) is provided in an inner circumferential surface of the bearing fitting hole (32b) into which the rolling bearing (34b) is fitted, for communication between a space (G1) that houses the speed reducer and an inside space (G2) of the bearing fitting hole, at a location not crossed by the line of action of a load acting upon the rolling bearing 34b due to the meshing of the gears.
