Abstract
In a double wishbone suspension structure, a damper coupling part at one end of a damper is coupled to either of a pair of coupling shafts for coupling an upper arm or a lower arm and a knuckle. Since impact from a wheel is not applied to an intermediate part of an arm and no bending moment acts upon the arm, the arm is not required to be reinforced and can be significantly decreased in size and weight. A damper attachment for attaching a damper to the arm is not required and the number of parts and manufacturing costs can also be reduced.

A double wishbone suspension structure comprising:
- a wheel side and a vehicle body side;
- a pair of upper arms and a pair of lower arms vertically swingably connected to the body side of the suspension structure, said upper and lower arms each having a first end and a second end, wherein said second ends are positioned on said vehicle body side of said suspension structure;
- an upper coupling shaft and a lower coupling shaft operatively connected to said respective first ends of said upper and lower arms;
- a knuckle on the wheel side being coupled to the respective first ends of the upper and lower arms via the respective upper and lower coupling shafts;
- a damper for dampening an impact transmitted from the wheel side to the vehicle body side;
- and
- a first end of the damper being coupled to either of the upper coupling shaft or the lower coupling shaft, wherein the first end of the damper coupled to the upper coupling shaft or the lower coupling shaft is coaxial with a central axis of the damper.
