Side panel structure for vehicle

摘要

A side panel structure (20), including a side outer panel (21) provided on the vehicle exterior side, and a side inner panel (22) provided on the vehicle interior (12) side. The side outer panel (21) and the side inner panel (22) form, as a closed cross-section structure, a peripheral edge section forming door openings (35, 36). The side outer panel (21) comprises an inner frame (26) formed from a high-strength steel sheet having a high tensile strength, and an outer frame (27) provided to the outer periphery section (26a) of the inner frame (26). The outer frame (27) is formed from a low-strength steel sheet having a low tensile strength.
