PROBLEM TO BE SOLVED: To provide the vibration free construction of a plastic molding body that prevents a tear of a hard elastic plastic spiral body by utilizing a soft elastic plastic bent pipe capable of recovering the effective elasticity or preventing the position shift due to an excessive bending, and has the effectiveness to aid the vibration absorption mutually. SOLUTION: This vibration free construction of a plastic molding body is constituted so that a hard flexible plastic spiral body with stiffness is connected with a soft flexible plastic spiral bent pipe. Various characteristic as an unit is obtained by mutual cooperation with the pressure resistance stiffness and the reversed flexibility of the flexible plastic spiral body and the vibration absorption effect and the damping function of the flexible plastic spiral bent pipe.
