PROBLEM TO BE SOLVED: To allow a tread width of a vehicle to be changed without changing suspension geometry while suppressing an increase in costs.SOLUTION: A suspension arm 16 includes: an arm portion 18 having one end portion 26 coupled to a front wheel 12 (wheel) side and the other end portion 27 coupled to a suspension member 25 of a vehicle body 14 side; an outer cylinder member 22 provided to the other end portion 27; and an inner cylinder member 24 being concentrically disposed radially inside the outer cylinder member 22 via a rubber bush in the other end portion 27, being capable of being coupled to the suspension member 25 and having protrusions in which a protrusion amount of the other end surface 22B side of the outer cylinder member 22 is set to be greater than that of one end surface 22A side thereof concerning protrusion amounts of the protrusions from both end surfaces while the protrusions are individually protruding from both the end surfaces of the outer cylinder member 22 in an axial direction of the outer cylinder member 22. |
