To efficiently supply lubricating oil to engaging elements.SOLUTION: A differential gear device comprises: an input shaft 32; a first output shaft 34; a second output shaft 33; a spider shaft 41 provided on the input shaft 32 so as to be rotatable integrally; a pinion gear 42 rotatably provided on the spider shaft 41; a first side gear 44 engaging with the pinion gear 42, and for transmitting power to the first output shaft 34; a second side gear 45 engaging with the pinion gear 42, and for transmitting power to the second output shaft 33; and a pump 50 capable of supplying lubricating oil to engaging parts between the pinion gear 42 and the side gears 44 and 45. The pump 50 is an internal gear pump comprising a pump housing 51, an outer rotor 58, and an inner rotor 59. The pump housing 51 is provided so as to be rotatable integrally with the first side gear 44. The inner rotor 59 is provided so as to be rotatable integrally with the input shaft 32 or the second output shaft 33.SELECTED DRAWING: Figure 4

    【課題】噛合要素に潤滑油を効率的に供給する。【解決手段】入力軸32と、第1出力軸34と、第2出力軸33と、入力軸32に一体回転可能に設けられたスパイダ軸41と、スパイダ軸41に回転自在に設けられたピニオンギヤ42と、ピニオンギヤ42と噛合すると共に、第1出力軸34に動力を伝達する第1サイドギヤ44と、ピニオンギヤ42と噛合すると共に、第2出力軸33に動力を伝達する第2サイドギヤ45と、ピニオンギヤ42とサイドギヤ44,45との噛合部に潤滑油を供給可能なポンプ50とを備え、ポンプ50は、ポンプハウジング51と、アウタロータ58及び、インナロータ59とを有する内接型ギヤポンプであり、ポンプハウジング51は、第1サイドギヤ44と一体回転可能に設けられ、インナロータ59は、入力軸32又は第2出力軸33と一体回転可能に設けられる。【選択図】図4
