Abstract
A vehicle transmission including a rotatable input shaft connected to a driving source; a countershaft parallel to the input shaft; a differential unit below the countershaft, to which rotation is input from the countershaft, and coupled to right and left wheels; a case member containing the input shaft, countershaft, and the differential unit; a differential chamber disposed in the case member, contains the differential unit, and is separated from an oil storage chamber; and a differential separation member separating the differential chamber from the storage chamber, and formed along the differential unit ring gear, which meshes with an output gear of the countershaft. The differential separation member has an opening so the output gear can mesh with the ring gear, a communication portion, formed in an upper part of the differential separation member, and located on an upstream side of the opening in a rotation direction of the ring gear during forward traveling, discharges oil from the differential chamber, and a wall member on a side of an output gear meshing portion and the ring gear with respect to the communication portion, and contacts the differential separation member outer surface.
