In a frame structure for a vehicle having a reinforcement body provided inside a frame body, the frame body comprises a first face portion and a second face portion extending in a direction substantially perpendicular to a rotational-axis direction of a bending moment occurring when a torsional load acts on a vehicle body, and third face portions positioned between the first and second face portions, and the reinforcement body comprises third-face connection portions connected to the third face portions, a first-face connection portion connected to the first face portion at a corner portion, a first-face non-contact portion provided away from the first face portion, a second-face connection portion connected to the second face portion at a corner portion, and a second-face non-contact portion provided away from the second face portion.

Frame structure for vehicle

An example molding method includes: feeding a molten foamable resin by injection in a cavity formed in a molding die; allowing the molten foamable resin to flow in the cavity; and foaming and solidifying the molten foamable resin to mold a resin foam product. The example molding method performs flow rate control by controlling a flow rate of the molten foamable resin at a welding portion to be equal to or higher than a flow rate of the molten foamable resin at an upstream portion adjacent to the welding portion.

Method and apparatus for molding resin foam product

Provided are a thermoplastic resin composition, a thermoplastic resin molded product and an outside plate part of a vehicle capable of improving both characteristics of heat resistance and impact resistance while being compatible with each other. The thermoplastic resin composition contains: 65 to 86.5 mass % of a polyamide resin component (A), 13 to 25 mass % of an acid modified elastomer component (B), and 10 mass % or less of an olefin-based resin component (C) and/or 8 mass % or less of a filler component (D), wherein a dispersion phase of a core-shell type particle structure that is formed from the acid modified elastomer component (B) serving as a shell phase and the olefin-based resin component (C) and/or the filler component (D) serving as a core phase is dispersed in a matrix phase formed from the polyamide resin component (A).
