<P>PROBLEM TO BE SOLVED: To provide an automatic transmission which suppresses a drop in oil pressure in a vehicle capable of stopping a power source during traveling. <P>SOLUTION: An automatic transmission comprises an oil pump (10m) which is rotated by the power of a drive power source (1) of a vehicle to generate oil pressure, a line pressure oil passage (39) in which at least line pressure generated by the adjustment of the oil pressure generated by the oil pump (10m) is supplied and a means (12) for stopping a driving power source during traveling which stops the rotation of the driving power source during vehicle traveling where the line pressure oil passage includes an oil pressure drop suppressing means for suppressing a drop in the line pressure accompanied by the reverse rotation of the driving power source when the rotation of the driving power source is stopped by the means for stopping the driving power source during traveling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
