摘要:
A heating method, a heating apparatus, and a hot press holding method for a plate workpiece are provided. The plate workpiece has a first region and a second region. A cross sectional area of the first region in a widthwise direction of the plate workpiece is substantially uniform along a longitudinal direction of the plate workpiece or is monotonically increased or decreased along the longitudinal direction. The second region is adjoining a portion of the first region in a monolithic manner. The method includes heating the second region, and heating at least the first region by direct resistance heating along the longitudinal direction. The second region is heated before heating the first region such that the first region and the second region are heated to be in a given temperature range.

A coupling structure includes a hollow rod section formed of a metal pipe and fastening sections formed by plastic deformation of the metal pipe so as to be connected with end sections of the hollow rod section. The fastening section includes a pair of base end sections which are each connected with a peripheral wall section forming a closed cross-section at the end section of the hollow rod section, and are separated from each other, and a bottom wall including a flat surface connected with the pair of the base end sections, and a pair of front end sections including a pair of side walls curving inwards from at least widthwise end sections of the bottom wall on a base end section side.
