Abstract: A front body construction of a vehicle includes a lengthwise front side frame welded to the lower periphery of each of left and right wheel houses in the form of a substantially quatered spherical segment. Inner and outer extension frames different in length extend from the front side frame and are laterally spaced apart from each other. To the outer extension frame an apron frame welded to an outer edge of the wheel house is welded at its lower end. A frontal impact force is received by the inner and outer extension frames, specifically by the longer one at first and, then, by the shorter one when a buckling or crushing is caused in the longer one due to frontal impact force.

Abstract: An arrangement for forming a rear partial structure of a vehicle body construction comprises, a rear end portion of a vehicle body forming an opening therein, a rear lamp assembly mounted on the rear end portion of the vehicle body so as to be disposed at a lower margin of the opening, and a tailgate mounted on the rear end portion of the vehicle body to be operative to open and close the opening. The tailgate includes a gate frame member which is attached through a hinge to the rear end portion of the vehicle body and a tailgate glass which is attached to the gate frame member and provided with an extended portion incorporated therewith to extend outward beyond at least a portion of one side of the gate frame member so as to cover therewith an outer surface of the rear lamp assembly when the tailgate is in a position for closing the opening.

Abstract: An automobile front body structure having an engine compartment defined therein, and also having a pair of spaced first longitudinal frames extending beneath the engine compartment in a direction longitudinally of an automobile and connected at a rear end to a floor panel. The front body structure comprises suspension arm support members secured to front ends of the first longitudinal frames, respectively, for the support of left-hand and right-hand suspension arms, and a transverse connecting member extending between the first longitudinal frames in a direction widthwise of the automobile and having its opposite ends connected to the respective support members.

Abstract: A motor vehicle front body structure including a dash panel separating the engine compartment from the passenger compartment. The dash panel has an upper portion which is inclined forward at an transversely intermediate portion and rearward at the transversely opposite end portions so that the upper edge portion of the dash panel has a forwardly convex configuration to conform with a corresponding configuration of the lower edge of the windshield glass.

Abstract: An arrangement for forming partially a vehicle body of the open-top type comprises a front header member provided at an upper end portion of a front windshield for interconnecting therethrough right and left front pillars which are provided at right and left side portions of the front windshield, respectively, and a center frame member including a lateral part which is connected at a front end portion thereof to a central portion of the front header member and elongates in the direction of the length of the body and a vertical part which elongates in the direction of the height of the body with its upper end portion connected to a rear end portion of the lateral part and its lower end portion connected to a floor panel member.

Abstract: A "hard-top" type automobile body having rear side panel structures formed at front edge portions with seats for rear edges of side doors. A rear pillar extends from each side panel structure to the roof. A longitudinal reinforcement member is provided in the side panel structure to extend from the door edge seat rearwardly to be connected with the rear pillar. The member further extends beyond the rear pillar and has a rear end connected with a transversely extending reinforcement so that the transverse rigidity of the rear side panel is increased at the area of the door edge seat without increasing the cross-section of the longitudinal reinforcement member.
