ABSTRACT:
A vehicle door (10) includes an inner door panel (11). The inner door panel includes a door frame (20) and elongated members (25, 26). The elongated members extend in a front-and-rear direction of a vehicle body. The elongated members have fragile sections (60) each extending in a widthwise direction of the vehicle body to provide a stepped portion. The fragile section fractures under the action of a fracturing stress produced when a compression force (FO) greater than predetermined intensity acts on the elongated members. One element of the elongated member having the thus fractured fragile section then moves to absorb the compression force, thereby enhancing a passenger protecting performance of the vehicle door.
