The invention discloses a shaft rod device of a vehicle drive shaft. The shaft rod device comprises a sliding end shaft rod (1) and a fixed end shaft rod (2), wherein the sliding end shaft rod (1) is used for being connected with a sliding end universal joint, and the fixed end shaft rod (2) is used for being connected with a fixed end universal joint and detachably connected with the sliding end shaft rod (1). A shock absorption part is arranged between the sliding end shaft rod (1) and the fixed end shaft rod (2) and can buffer axial shocks. The shocks in the axial direction can be effectively buffered and absorbed through the shaft rod device, NVH of a drive shaft assembly are improved, and the shaft rod device is convenient to detach and maintain.
