Abstract
A friction-plate lubricating device for an automatic transmission that includes a friction engagement element with a plurality of friction plates in which outer friction plates and inner friction plates are alternately disposed; a hub with splines engaged with teeth formed on an inner circumference of the inner friction plates, the hub having the splines on an outer circumference thereof and having uneven portions formed on an inner circumference thereof; and a nozzle that discharges lubricant to the uneven portions. Recesses of the uneven portions serve as oil reservoirs in which the lubricant gathers, and through-holes are formed in bottom surfaces of the recesses. The lubricant discharged from the nozzle is collected in the oil reservoirs formed by the recesses so as to be supplied to the plurality of friction plates of the friction engagement element through the through-holes.
