PURPOSE: A drawn device for a thermal-contraction tube is provided to enable to drawn-process resin which glass transition temperature is over 80-90 deg. C and to replace only a cooling unit according to final diameter of the thermal-contraction tube to manufacture. CONSTITUTION: A drawn device for a thermal-contraction tube comprises a drawn unit(10) and a cooling unit(20). The drawn unit comprises a drawn pipe(11), a heating member(12), and an auxiliary heater(13). The drawn pipe passes the thermal-contraction tube(T) of initial diameter(d1) and the heating member heats to the thermal-contraction tube. The auxiliary heater is connected to surround outer circumference of the drawn pipe, is heated, and delivers the heat inside the drawn pipe. The cooling unit comprises a cooling pipe(21) and a cooling member(22). The cooling pipe passes the thermal-contraction tube in the inside. The cooling member cools the thermal-contraction tube to be harden as final diameter(d2) state corresponding to inner diameter of the cooling pipe.
