PROBLEM TO BE SOLVED: To provide a vehicular differential gear having increased house-strength. SOLUTION: In the vehicular differential gear, first and second holding holes 21, 22 are made in a body part 2A so as to hold respectively rotatably first and second planetary gears, and a third and fourth holding holes 23, 24 are made to rotatably hold first and second transfer gears 7, 8. The first and second holding holes 21, 22 are made blind, and provided respectively in one and the other ends of the body part 2A. First and second support-wall parts 31, 32, which are made continuous with each other in the circumference of the body part 2A, are formed respectively between the third and fourth holding holes 23, 24 and the internal circumferential surface of the body part 2A. One circumferential side of the end part, which is located on the side of the second holding hole 22 of the first support-wall part 31, is made continuous to the other part of the body part 2A. The other circumferential end of the end part, which is located on the side of the first holding-hole 21 of the second support-wall part 32, is made continuous to the other part 42 of the body part 2A.
