To provide a parking mechanism for a transmission configured to reduce the number of parts constituting a parking mechanism included in a conventional transmission is reduced.
The parking mechanism for a transmission with a planetary gear mechanism for speed changing and outputting the rotation of a driving force source (20), includes a plurality of friction elements (33, 34) which change a speed ratio of the planetary gear mechanism by being engaged or released; and an engaging unit which engages the friction elements (33, 34). The engaging unit maintains at least two interlock friction elements in engaged states out of the plurality of friction elements (33, 34), the two interlock friction elements being engaged to bring the transmission into an interlocked state when the operation of the driving force source (20)stops due to a key-off operation.
