The present invention relates to a lubrication structure of a clutch for an automatic transmission. The lubrication structure of a clutch for an automatic transmission comprises: multiple retainers and hubs which are connected to multiple disk sets, respectively; multiple pistons which are formed in one side of the disk sets, respectively, to press plates and disks formed in the disk sets; and multiple return springs and balance pistons which are formed in one side of the pistons, respectively, to apply restoring force to the pistons. The pistons and the balance pistons form a chamber. Discharge holes for guiding oil flowing into the chamber to one among the disks formed in the disk sets are formed in the hubs, the pistons, or the balance pistons, thereby improving the lubricating and cooling performance of the disk sets. |
