To provide a suspension link excellent in precision and functional property with simple minimum working by providing a hole connected to the car body side and rear swing side and a hole connected to a buffer having the same dimension widthwise of an autocycle.

An extruded material 40 to provide a link is a long aluminum material formed by extrusion molding method such that the aluminum material with approximately triangular cross section is provided inside the proximity of each apex of the triangle longitudinally with first, second and thirs holes 44, 45 and 46 and in the intermediate part with a lightening part 4 to lighten itself. This extruded material 40 is cut off to the uniform width same as the width of an autocycle longitudinally. Since the extruded material 40 is cut off to the predetermined width, the obtained link has accurate precision in the width dimension W and the desired precision of the inner diameter dimension is obtained in the respective holes 44, 45 and 46. Further, the respective holes 44, 45 and 46 are connecting holes of a rear swing arm through a car body, hydraulic buffer and tension rod.
