PROBLEM TO BE SOLVED: To reduce the bending moment around a connecting part center point of a suspension part.SOLUTION: A vehicle suspension device comprises a third link 9 to which the outside of an upper arm, a shock absorber lower end and a knuckle upper part are connected. A connecting part center point between the shock absorber lower end and the third link 9 is set as a point A, a connecting part center point between the shock absorber upper end and a vehicle body is set as a point B, a king pin rotation axis center point being a connecting part between the knuckle 5 and the third link 9 is set as a point C, a connecting part center point between the outside of the upper arm and the third link is set as a point D, and a line component which connects the point A and the point D is set as a line component AD. When a caster angle is a rearward-inclined angle, the point B is arranged so as to be offset to a vehicle rear position in an upper face view with respect to the line component AD, the point C is arranged so as to be offset to a vehicle front position in the upper face view with respect to the line component AD, and the point D out of the point A, the point B, the point C and the point D is arranged in a position at the outermost side of a vehicle in the upper face view. The upper arm 11 and the shock absorber 10 are arranged so that a positional relationship between and among the point A, the point B, the point C and the point D is established. |
