PURPOSE: A rotational support device of an extruder cross head is provided to support the extruder cross head steadily and separate the extruder cross head regardless of machines which are adjacent to the extruder cross head. CONSTITUTION: A rotational support device of an extruder cross head comprises a supporting board(10), a horizontal moving board(30), a rotation support plate(40), and a rotating disc(50). Two parallel rails are formed on an upper surface(11) in the longitudinal direction in a table shape of the supporting board. A stopper is installed at the end of the supporting board. In a horizontal moving board, a circular center hole(32) is formed at the middle of a plate body(31). A rotation support plate fixes the location by inserting an anchoring bolt(43) in a bolt hole formed in a plate body(41). In the rotating disc, a taper bearing(70) and a ball bearing(71) are installed.
