Abstract:
A vehicle transmission comprising:a group of parts including at least an input gear and an output gear which are stacked and supported on a shaft supported in casings via at least one pair of bearings, a torque that has been input to the input gear being output from the output gear, wherein: the input gear and the output gear are helical gears; first and second thrust forces acting on the input gear and the output gear, respectively, are generated in opposite directions; one of said first thrust force and said second thrust force is borne by the casing via a shaft end of the shaft; the other of said first thrust force and said second thrust force is borne by the casing via a side of the output gear; a retaining part integrally formed on the shaft for restricting movement of one of the input gear and the output gear in the direction in which the one departs from the other; and a retaining means detachably provided on the shaft for restricting movement of the other of the input gear and the output gear in the direction in which the other departs from the one, wherein a thrust bearing is interposed between the casing and the output gear so as to engage only the casing and the output gear.
