Abstract
A driving force transmitting apparatus includes a clutch drum having a cylindrical portion, an inner shaft having an end housed in the clutch drum, a friction clutch having outer clutch plates that rotate along with the clutch drum and inner clutch plates that rotate along with the inner shaft, a piston that presses the friction clutch, and a housing in which a first housing chamber housing the friction clutch is formed. The friction clutch is lubricated with a lubricant fed through an opening. The housing is provided with a storage chamber in which the lubricant scooped up by rotation of the clutch drum is stored and a lubricant supply hole which allows the lubricant stored in the storage chamber to be fed from inside the piston to the first housing chamber.
