Abstract
Differential apparatus capable of guiding and supplying a sufficient amount of lubricant oil to the lubrication elements accommodated in the differential apparatus (). The differential apparatus comprises a differential case (), a differential carrier (), a carrier cover (), a differential mechanism housed in the differential case, and a ring gear () secured to the ring differential case. The differential case has a through bore () radially formed in differential case to have the inner space of the differential case held in communication with the outer space of the differential case. The differential carrier has a lubricant oil reservoir portion () positioned below the differential case to reserve the lubricant oil therein. The carrier cover is secured to the differential carrier and has a lubricant oil flow guide portion () vertically extending in the vicinity of and in side-by-side relationship with the outer circumferential portion of the ring gear to guide the lubricant oil of the lubricant oil reservoir portion stirred up with the rotation of the ring gear and to discharge the lubricant oil toward the central portion of the differential mechanism.
