Abstract:
A fluid-type torque transmission device comprising:a front cover; an impeller being fixed to said front cover to form a fluid chamber; a turbine disposed inside said fluid chamber in a space between said front cover and said impeller; and a lockup device comprising, a clutch-purpose friction plate being configured to be coupled with said front cover to rotate integrally therewith, a pair of drive members comprising, first and second disk-shaped members being disposed to be spaced apart from each other in an axial direction, a cylindrical part extending from an outside circumferential edge of said second disk-shaped member toward said first disk-shaped member, said cylindrical part engaging with an inside circumferential edge of said friction plate, said friction plate being non-rotatable and axially movable relative to said cylindrical part, and a fixing part formed on said cylindrical part of said second disk-shaped member, said fixing part being bent radially inward and fixed to said first-disk shaped member, a driven member being fixed to said turbine, and an elastic member being configured to be compressed when said pair of drive members and said driven member rotate relative to each other.
