In a vehicle-body structure of a vehicle, where suspension forming members are attached to a vehicle body, there are provided a first face portion, through which the suspension forming member extends, a second face portion provided to face to the first face portion, and a support member provided between the first face portion and the second face portion and supporting the suspension forming members, and the support member is joined to said second face portion via a reinforcing member which is formed integrally with the support member or formed separately from the support member. Accordingly, vibrations of the support member can be properly restrained.

Vehicle-body structure of vehicle and manufacturing method of the same

In a vehicle-body structure of a vehicle which comprises at least one vehicle-body forming member forming a closed-section portion continuously in a specified direction, a partition member extending in the specified direction and partitioning an inside of the closed-section portion, and a bulkhead provided in the closed-section portion and joined to the vehicle-body forming member, the bulkhead is joined to an inner face of the vehicle-body forming member at specified positions which are located on both sides of the partition member, and the bulkhead is joined to a specified portion of the partition member which is located in the vicinity of opening portions formed at the partition member or to an end portion of the partition member in the specified direction.

In a vehicle-body structure of a vehicle which comprises vehicle-body forming members forming a closed-section portion and having a dent portion which dents toward an inside of the closed-section portion, and a reinforcing member provided in the closed-section portion and joined to the vehicle-body forming members, a joint portion of the vehicle-body forming members and the reinforcing member includes a rigid joint portion where the vehicle-body forming members and the reinforcing member are joined with a direct contact thereof and a flexible joint portion where the vehicle-body forming members and the reinforcing member are joined via a damping member provided therebetween, and this joint portion is provided at or in the vicinity of the dent portion.

In a frame having a closed-section portion which is formed by joining a first member having a U-shaped section and a second member having a flat-plate shape, a bulkhead is provided in the closed-section portion as a reinforcing member, flanges of the bulkhead and the first and second members are joined with a rigid joint portion where they are joined by a spot welding and a flexible joint portion where they are joined via a damping member. Thereby, transmission of vibrations can be properly restrained, improving the rigidity of the portion having the closed-section portion.

A support mount bracket () provided on a vehicle frame () and configured to support a mount part () of a front differential gear unit () is arranged on part of a cross-member () connecting a pair of right and left main frames () so as to be, in a vehicle width direction, displaced from the center of a vehicle () in a width direction thereof. The support mount bracket () includes a base part () to be connected to the cross-member (), and a pair of fixing parts () protruding from the base part () and sandwiching the mount part () from sides thereof in the vehicle width direction. One () of the fixing parts () on a side closer to the center of the vehicle () in the width direction thereof is detachably attached to the base part ().
