PROBLEM TO BE SOLVED: To provide an anti-vibration connecting rod excellent in durability and low in cost. SOLUTION: In a first anti-vibration bush 18 arranged in the first cylindrical part 12 of a rod body 16 which is composed of a resin material, the first anti-vibration bush is constituted of an inner cylinder metal fitting 28 arranged in the first cylindrical part axially in parallel therewith, an outer cylinder metal fitting 30 which surrounds the inner cylinder metal fitting axially in parallel therewith, and an anti-vibration base body 32 composed of a rubbery elastic body which is interposed between the inner cylinder metal fitting and the outer cylinder metal fitting. The anti-vibration base body 32 has a pair of elastic connecting parts 44 for supporting inner and outer cylinders on both sides with the inner cylinder metal fitting 28 interposed therebetween in a direction M perpendicular to the longitudinal direction L of the rod body 16. The outer cylinder metal fitting 30 is formed into an oblong cylindrical shape in cross section in which a diameter D2 in the direction M perpendicular to the longitudinal direction is larger than a diameter D1 in the longitudinal direction L, and is connected and held in the first cylindrical part 12 with the injection molding of the rod body 16.
