摘要： A power transmission device including a transmission, a case housing the transmission, a brake including a plurality of frictional engaging plates and a piston for pressing the frictional engaging plates and configured to non-rotatably hold any one of rotation elements of the transmission stationary to the case, and a support fixed to the case and including a ring-shaped wall portion extending in a radial direction of the transmission, a drum portion extending from the ring-shaped wall portion in an axial direction of the transmission and non-rotatably supporting a part of the frictional engaging plates, and a boss portion extending from the ring-shaped wall portion toward a side opposite to the frictional engaging plates in the axial direction and rotatably supporting another rotation element of the power transmission device.

摘要： A power transmission apparatus including a transmission, a case that accommodates the transmission, a counter drive gear to which power from the transmission is transmitted, and a counter driven gear that meshes with the counter drive gear, the power transmission apparatus including: a brake that fixes any rotational element of the transmission to the case so as not to be rotatable; and supporting member that is fixed to the case via a fastening member and that supports the counter drive gear so as to be rotatable, wherein the supporting member is integrally molded with a cylindrical drum portion that functions as a brake drum of the brake.
