PROBLEM TO BE SOLVED: To provide a differential device which has a simple device structure, achieves low manufacturing costs, and smoothly supplies a lubrication oil to a slide portion between a differential case and a drive shaft.SOLUTION: A differential device 30 includes: a differential gear mechanism 35; a differential case 36; a differential housing 37; and an oil feed tube 74 in which a lubrication oil flows. The differential device 30 includes: an oil reservoir part 62 which communicates with a shaft insertion part 36y and may accumulate the lubrication oil; an oil passage 66 which may introduce the lubrication oil to the oil reservoir part 62; and an internal pressure release passage 72 for communicating the interior and the exterior of the oil reservoir part 62 and releasing the internal pressure of the oil reservoir part 62. A jet port 80 for the oil passage, which may jet the lubrication oil to the oil passage 66, is formed in the oil feed tube 74. Further, a guide plate 90 for guiding the lubrication oil scraped by a differential ring gear 31 to the oil passage 66 is provided. |
