Claim 8:
9. A vehicle drive transmission device, comprising:
a first friction plate and a second friction plate arranged in an axial direction;
a friction clutch device including a press member configured to press the first friction plate and the second friction plate in the axial direction;
a first support supporting the first friction plate from an outer side in a radial direction; and
a second support supporting the second friction plate from an inner side of the second support in the radial direction, wherein
the first support is open toward a first side in the axial direction,
the second support includes:
a cylindrical support section extending in the axial direction and supporting the second friction plate; and
a radial extension section extending in the radial direction on an inner side of the cylindrical support section in the radial direction and coupled to the cylindrical support section,

the press member is at such a position as to press the first friction plate and the second friction plate from the first side in the axial direction,
the second support further includes a protrusion protruding from the cylindrical support section toward the first side in the axial direction,
the press member has an insertion hole extending through the press member in the axial direction and configured to receive the protrusion, and
the cylindrical support section, the radial extension section and the protrusion are integrally formed.
