摘要： A press formed article such as a center pillar or the like for a vehicle having a demanded strength distribution achieved by hardening through induction hardening or the like, and a method and an apparatus for performing induction hardening on the press formed article. The center pillar (10) being a press formed article has an intermediate top portion (11) which extends in a longitudinal direction of the center pillar (10), and two blade portions (12) which are both bent in the same direction from both sides of the intermediate top portion (11), in which hardening regions (Q) are provided on both sides of the intermediate top portion (11), extending over the intermediate top portion (11) and the blade portions (12). These hardening regions (Q) hardened by the induction hardening apparatus are regions in a form which widens toward the end and continuously expand from the upper portion to the lower portion of the center pillar (10). Therefore, the ratio between the hardening regions and non-hardening regions changes in the longitudinal direction of the center pillar (10), resulting in a demanded strength distribution.

When a region to be heated of an article made of a thin sheet is heated inductively so that the whole region thereof reaches a temperature equal to or more than a target temperature using an inductive portion of a heating inductor to which a high-frequency current is applied by a power supply device, by providing a period to stop or reduce temporarily the power application of the high-frequency current to the heating inductor during the temperature increase, a temperature difference in the region to be heated is reduced so that the unevenness of the temperature increase at the end of the heating work is reduced by the step of reducing the temperature difference.

摘要： A vehicle door which can be used as a tailgate or a side door of a vehicle and a manufacturing method of this vehicle door is provided. A tailgate (1) which is a vehicle door is formed of an outer panel (2) on an outer side of a vehicle, an inner panel (3) on an inner side of the vehicle, and a module plate (4) to which door parts such as a wiper motor (18) are attached, and a lining (6). The inner panel (3) is in a frame shape with only a marginal portion (10) of the whole periphery left and with an opening (11) formed therein, which results in reduction in the weight of the tailgate (1). The module plate (4) which also serves as a reinforcing member is composed of a first extending portion (13) extending in a right and left direction and a second extending portion (14) extending downward from the first extending portion (13) to be in a substantially T-shape, which also results in reduction in the weight of the module plate (4), and connection of the module plate (4) to the outer panel (2) and the inner panel (3) reinforces the tailgate (1).
