PROBLEM TO BE SOLVED: To provide a vehicular reduction gear which can be easily manufactured or assembled, capable of smoothly supplying lubricant to a bearing device of a type wherein a shaft is arranged so as to extend upward. SOLUTION: The vehicular reduction gear is composed such that a bearing cage 21 is provided in a penetrating part 4 formed in an upper side wall plate 2A, a ring body 22 is provided so as to freely abut on the bearing cage from an upper side, an input shaft 10 is rotatably supported in a bearing cage side via bearings 24A and 24B, a seal body 26 is provided between the ring body and the input shaft, and a plurality of lubricant introducing paths 30 guiding lubricants OA and OB running along an inner face 1a of the upper side wall plate to a part above the bearings are formed from the upper side wall plate to the bearing cage and the ring body. A plurality of ribs 2H and 2I extending radially with respect to an axis of the input shaft are protrudedly formed in an inner face side of the upper side wall plate, lubricant guiding faces 2h and 2i are formed by longitudinal faces of the ribs, and inlet ends 31 of the lubricant introducing paths are positioned in inner end side positions of the lubricant guiding faces.
