Abstract:
1. A hollow panel comprising: an extruded aluminum panel body formed in a structure such that a plurality of plate-like members are joined by a plurality of ribs, the panel body comprising an open space portion and a closed space portion; and a joined member forming an open space having an opening and joined to the panel body, the joined member being formed of a material stronger than the material of the panel body, wherein the open space portion of the panel body is formed so as to extend in a predetermined direction and is formed as an open space in a cross-section perpendicular to the predetermined direction, wherein the closed space portion has a shape such that a plurality of closed spaces are defined by the ribs between the plate-like members in a cross-section perpendicular to the predetermined direction, and wherein the joined member is press-fitted into the open space portion of the panel body such that the open space of the joined member is exposed to the exterior of the hollow panel, wherein the open space portion of the panel body comprises a pair of protruding portions formed so as to extend in the predetermined direction and provided so as to be opposite each other across an opening, and wherein the pair of protruding portions are in contact with a side of the joined member press-fitted into the open space portion of the panel body such that the opening of the open space portion and the opening of the joined member are aligned with each other so that the open space of the joined member is reached from outside of the hollow panel by sequentially passing through the opening of the open space portion of the panel body and the opening of the joined member.
