Connection member for vehicle structure

A connection member for a vehicle structure equipped with at least two connection sections that connect appropriate sites within the vehicle structure, the connection member being characterized by having a columnar layered structure section configured by impregnating a layered body in which a plurality of fiber bodies have been winded with a matrix resin and curing the impregnated layered body, and employing, as the fiber bodies, bodies in which bundles of unidirectionally aligned carbon fibers have been interwoven with thermally fusible fibers, and the connection sections being configured from metal bodies affixed to the layered structure section,

• wherein end section of the layered structure are provided with the connection sections, and the connection sections comprise cross-shaped slits,
• wherein the end sections of the layered structure are divided and comprise first parts and second parts with an axis of symmetry between the first parts and the second parts,
• wherein the cross-shaped slits are formed in each layer of the layered structure such that first angles of first cross-shaped slits of the first parts symmetrically correspond to second angles of second cross-shaped slits of the second parts based on the axis of symmetry,
• wherein at least one of the first cross-shaped slits is formed at 45° relative to a 0° longitudinal direction of the layered structure section, and at least one of the first-cross-shaped slits is formed at −45° relative to the longitudinal direction of the layered structure section,
• wherein the metal bodies are provided with a flange-form section on a circumferential surface of a main body serving as the axis of symmetry, and
• wherein a number of layers of the first parts on an upward side of the flange-form section is equal to a number of layers of the second parts on a downward side of the flange-form section.
