摘要

This automobile member has a closed cross section including joint portions in which edge portions of two vertical walls of an inner panel are joined with edge portions of two vertical walls of an outer panel, wherein: in a first region, a first region outer height ho1 and a first region inner height hi1 have a constant value and the difference between the first region outer height ho1 and the first region inner height hi1 is smaller than the difference between a second region outer height ho2 and a second region inner height hi2; in a second region, the second region outer height ho2 has a value which is greater than the second region inner height hi2 and constant, or the second region outer height ho2 has a value which is smaller than the second region inner height hi2 and constant; in a first transition region, a first transition region outer height ho1-2 is continuously varied between the first region outer height ho1 and the second region outer height ho2, and a first transition region inner height hi1-2 is continuously varied between the first region inner height hi1 and the second region inner height hi2.
