車機能付き自動変速機。[Claims for Utility Model Registration] 1. Uphill road stopping function in which a rotational force transmission path is formed by engaging the band brake so that the rotation of the output shaft in the backward direction is prevented by the action of the one-way clutch. Automatic transmissions with automatic transmissions are equipped with two hydraulic servo devices that can each apply a tightening force from both ends of the band brake. An automatic transmission with an uphill road stopping function, characterized in that the automatic transmission is configured to operate a hydraulic servo device on the side that puts the band brake in a leading state and the band brake in a trailing state when the engine is driving. 2. The automatic transmission with an uphill road stopping function according to claim 1, wherein a band brake with a drum wrapping angle of 360 degrees or more is used.
