Driving force distribution apparatus

A driving force distribution apparatus that distributes and outputs, to first and second output rotary members, a driving force input from a driving source, the driving force distribution apparatus comprising:

• a case member in which lubricating oil is stored;
• a shaft that receives the driving force and rotates in the case member;
• a clutch housing that is restrained from rotating relative to the shaft, the clutch housing including a cylindrical portion having a cylindrical shape, and a bottom wall portion extending radially inward from an axial end of the cylindrical portion;
• a first multi-disc clutch including a plurality of clutch plates disposed between the cylindrical portion of the clutch housing and the first output rotary member;
• a second multi-disc clutch including a plurality of clutch plates disposed between the cylindrical portion of the clutch housing and the second output rotary member;
• a first pressing mechanism that presses the first multi-disc clutch;
• and
• a second pressing mechanism that presses the second multi-disc clutch;
• wherein
• the first multi-disc clutch is disposed closer to the bottom wall portion in the clutch housing than the second multi-disc clutch is;
• the first pressing mechanism includes a pressing member including legs inserted in insertion holes formed in the bottom wall portion of the clutch housing, and an annular pressing portion disposed between the bottom wall portion and the first multi-disc clutch;
• and
• the pressing member includes a lubricating oil introduction portion that guides the lubricating oil supplied from a clearance between the first output rotary member and the bottom wall portion toward the first multi-disc clutch.
