Abstract
An automatic transmission for a vehicle having a planetary gear mechanism, which is accommodated in an automatic transmission case, is provided with an accordion-like leaf spring disposed in a gap for allowing interior spaces of an automatic transmission case to communicate with each other, the gap being provided in the automatic transmission case between an outer peripheral surface of axially movable brake elements which are fixed against rotation on the one hand, and an inner peripheral surface of the automatic transmission case on the other. The accordion-like leaf spring is adapted to engage and bias a friction plate and has folded-back portions or pleats that lie generally parallel to the rotating shaft.
