A lubricating device of an automatic transmission includes a partitioning member (91) that partitions an oil chamber (73), to which a lubricating oil of a first oil chamber (71) is introduced; a second oil chamber (73a) partitioned by the partitioning member (91) and to which lubricating oil to supply to a forward clutch (20) is introduced; and a third oil chamber (73b) partitioned by the partitioning member (91) and to which lubricating oil to supply to a pinion unit such as a pinion gear (P) coupled with one engagement unit of the forward clutch (20) is introduced; wherein a clutch oil path (24d) that introduces the lubricating oil of the first oil chamber (71) to the second oil chamber (73) and a pinion oil path (24e) that introduces the lubricating oil of the first oil chamber (71) to the third oil chamber (73b) are formed in a clutch drum (24) interposed between the first oil chamber (71) and the oil chamber (73); and an oil path switching member (81) that opens the clutch oil path (24d) and interrupts the pinion oil path (24e) at time of clutch engagement, and that interrupts the clutch oil path (24d) and opens the pinion oil path (24e) at time of clutch release is arranged. |
