  • Structure for improving strength of tabular portion and substantially rectangular parallelepiped member
    Patent number: 9461580
    Abstract: A polygon in a tabular portion includes first and second axes of symmetry substantially orthogonal to each other. A top surface of the tabular portion has a swelling portion with an outline that is line-symmetric with respect to the first and second axes of symmetry. In a lateral half portion of the outline, a short-side side crest portion that is convex toward the polygonal outline in the direction of the first axis of symmetry, concave corner-side trough portions connected to each end of the short-side side crest portion and long-side side crest portions that are connected to each corner-side trough portion and convex toward the polygonal outline are formed. On one of a top surface and an undersurface of the swelling portion, a pair of lateral ribs or a pair of longitudinal ribs that spreads toward the polygonal outline and transversely crosses the swelling portion is formed.
