Abstract
A lubricating structure of an automatic transmission is provided which is capable of realizing sufficient cooling lubrication with lubricating oil, utilizing a given space efficiently, and avoiding the possibility of an increase in the weight of assembly parts by checking an increase in the number of the assembly parts. The rotational direction of a front planetary gear device (46) and the like is changed by engagement or disengagement of each of multiplate clutch plates (35, 43) of a plurality of multiplate clutch devices (33, 40), and thereby the transmission state of driving force is shifted. A 2-4 brake clutch (33) of the multiplate clutch devices (33, 40) is engaged in two forward gears and is disengaged in a forward gear between the two forward gears. A reverse clutch (40) of the multiplate clutch devices (33, 40) is disposed substantially in the same position as that of the 2-4 brake clutch (33) in the axial direction and outside of the 2-4 brake clutch (33) in the radius direction. The reverse clutch (40) uses a clutch drum (36) of the 2-4 brake clutch (33) as a clutch hub.
