To provide a coupled vehicle of a track system having a coupling device on upper and lower coupling units between vehicle bodies for ensuring the traveling stability capable of efficiently enhancing the traveling stability and the ride quality when the vehicle travels on a curve at low cost.
An upper coupling device comprises a first coupling device 3 which is provided on at least one coupling unit present between trucks 1 to permit the relative yawing and rolling between the vehicle bodies, a second coupling device 4 which is provided on at least one place out of coupling units present between three trucks 1 to permit the relative yawing, rolling and pitching between the vehicle bodies, and a third coupling device 5 which is provided on other coupling units other than the first coupling device 3 and the second coupling device 4 to permit only the relative yawing between the vehicle bodies. A lower coupling device 6 is constituted of a pair of spherical joints to be fitted to each other.
