<P>PROBLEM TO BE SOLVED: To restrain or prevent the occurrence of rattle of a carrier 44 provided in a planetary gear mechanism 40, in a driving device 1 configured to store the planetary gear mechanism 40 in a case 3 filled with oil. <P>SOLUTION: A first annular plate 441 of the carrier 44 is prevented from rotating in the case 3 with play in a circumference direction thereof. The case 3 is provided with oil paths 3d for introducing oil to end-face openings of respective oil holes 443a of respective pinion shafts 443. Oil which is introduced from the oil path 3d in the case 3 to the end-face opening of the oil hole 443a on the pinion shaft 443 pushes the carrier 44 in one circumference direction thereof, and thus play in the circumference direction of the carrier 44 relative to the case 3 is configured to be shortened in the one circumference direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
