Abstract

Official abstract text for this publication.

A lubrication structure of a driving force transmission apparatus includes a rotating shaft, a friction engagement device, a piston member, a piston housing, a component, a piston chamber, a moving member, a holding member, a rotation stopper, and a hydraulic oil path. The rotating shaft has a shaft direction and is rotatable around the shaft direction. The friction engagement device includes a friction engagement unit which is arranged around an outer circumference of the rotating shaft and in which a plurality of friction materials are alternately laminated along the shaft direction. The piston member is provided movably along the shaft direction to press the friction engagement unit so that the plurality of friction materials engage with each other. The piston housing houses the piston member.
