Abstract
An automatic transmission includes a parallel-axis gear pair including a first gear having a shaft portion and a gear portion, and a second gear which meshes with the first gear; a case that has a supporting wall which is adjacent to the gear portion of the first gear and rotatably supports the shaft portion of the first gear; and a frictional engagement apparatus that includes friction members, a piston that presses on, so as to apply, the friction members, and a hydraulic chamber that holds hydraulic fluid which moves the piston in the direction of the friction members. As a result, both the shaft to shaft dimension as well as the axial dimension of the automatic transmission can be reduced.
