A multi-stage transmission that includes a case including an annular support that extends radially inward from an inner peripheral surface of the case; a first planetary gear mechanism that includes a plurality of rotating elements and to which power is transmitted from the input member; a second planetary gear mechanism that is disposed on an opposite side of the support of the case from the first planetary gear mechanism; a clutch that interconnects any one of the rotating elements of the first planetary gear mechanism with an element to be connected which is included in the second planetary gear mechanism and releases this interconnection; and a brake that connects the element to be connected to the case to hold this element stationary and releases this connection.
