Abstract

A rear vehicle-body structure of a vehicle comprises a wheel house, a side frame, a suspension comprising a damper and a spring, and a suspension housing connecting the side frame and the wheel house. The suspension housing includes a supporting part for supporting the damper and a spring receiving part for supporting an upper end portion of the spring at a position located on an outward side, in a vehicle width direction, of the side frame and on an upward side, in a vehicle vertical direction, of a lower end of the side frame. Further, connection portions connecting, in the vehicle vertical direction, the side frame and the spring receiving part are provided on a downward side, in the vehicle vertical direction, of the spring receiving part.

Claims

1. A rear vehicle-body structure of a vehicle, comprising:

a wheel house provided at a side face portion of a vehicle-body rear portion and housing a wheel;

a side frame extending in a vehicle longitudinal direction on an inward side, in a vehicle width direction, of the wheel house;

a suspension comprising a damper extending in a vehicle vertical direction on an outward side, in the vehicle width direction, of the side frame and a spring arranged around the damper and suspending the wheel at a position below the spring; and

a suspension housing including a supporting part for supporting the damper and provided to connect the side frame and the wheel house,

wherein said suspension housing includes a spring receiving part for supporting an upper end portion of said spring at a position which is located on an outward side, in the vehicle width direction, of said side frame and on an upward side, in the vehicle vertical direction, of a lower end of the side frame, and a connection portion which connects, in the vehicle vertical direction, the side frame and said spring receiving part is provided on a downward side, in the vehicle vertical direction, of the spring receiving part.

2. The rear vehicle-body structure of the vehicle of claim 1, wherein a lower face of said spring receiving part is substantially of a circular shape, and a through hole for inserting said damper is provided at the spring receiving part.

3. The rear vehicle-body structure of the vehicle of claim 1, wherein said suspension comprises a bump stopper which is arranged on the downward side, in the vehicle vertical direction, of said supporting part, said suspension housing includes a peripheral wall portion which is provided to extend downward from the supporting part and enclose said bump stopper, and said spring receiving part is provided to expand radically outside from a lower edge of the supporting part in a flange shape.

4. The rear vehicle-body structure of the vehicle of claim 2, wherein said suspension comprises a bump stopper which is arranged on the downward side, in the vehicle vertical direction, of said supporting part, said suspension housing includes a peripheral wall portion which is provided to extend downward from the supporting part and enclose said bump stopper, and said spring receiving part is provided to expand radically outside from a lower edge of the supporting part in a flange shape.

5. The rear vehicle-body structure of the vehicle of claim 1, wherein said suspension housing comprises a high-rigidity portion which extends along the peripheral edge portion of said spring receiving part discontinuously or continuously.

6. The rear vehicle-body structure of the vehicle of claim 2, wherein said suspension housing comprises a high-rigidity portion which extends along the peripheral edge portion of said spring receiving part discontinuously or continuously.

7. The rear vehicle-body structure of the vehicle of claim 3, wherein said suspension housing comprises a high-rigidity portion which extends along the peripheral edge portion of said spring receiving part discontinuously or continuously.

8. The rear vehicle-body structure of the vehicle of claim 4, wherein said suspension housing comprises a high-rigidity portion which extends along a peripheral edge portion of said spring receiving part discontinuously or continuously.
