Document Type and Number:
Japanese Patent JP6747362
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a friction plate for a transmission, capable of supplying lubricant to a loading range at sufficiently high oil pressure, even in a case where the loading range is distributed to an outer peripheral edge side portion of a friction surface of the friction plate.SOLUTION: A driven plate 81 includes: a plurality of cores 85 arranged annularly at intervals; a pair of annular surface plates 86 provided on both sides of the plurality of cores 85, and sandwiching the plurality of cores 85 from both sides; a lubricant flow passage 81b formed by a gap between adjacent cores 85; and a plurality of discharge holes 81d provided on the annular surface plate 86, and configured to discharge lubricant from the lubricant flow passage 81b to a friction surface 81c of the annular surface plate 86. A lateral width W2 of the lubricant flow passage 81b is made gradually smaller from an inner peripheral edge side of the annular surface plate 86 toward an outer peripheral edge side thereof.SELECTED DRAWING: Figure 4
