PURPOSE: A tandem suspension adopting a ready earth rod is provided to improve fuel efficiency by reducing the weight of a vehicle body and displaying a smooth suspension action and to reduce the number of assembling processes by reducing the number of parts. CONSTITUTION: An upper front ready earth rod(1) is hinge-coupled to the upper portion of a front vehicle shaft(112a) and installed toward the rear portion. An upper rear ready earth rod(3) is hinge-coupled to the upper portion of a rear vehicle shaft(112b) and installed toward the front portion. The upper front ready earth rod and the upper rear ready earth rod are coaxially connected. The common rotating shaft is connected to suppress the relative rotation of the upper front and rear ready earth rods. The common rotating shaft is realized by an upper connecting member rotatably supported on a frame(100).
