PURPOSE: To improve the effective life of a flat receiver for an extrusion molding machine by constituting this receiver of a non-circular hole inner bushing having curvilinear chamfered part on the short sides of a cross-section and another portions shrinkage fitted thereto.

CONSTITUTION: The flat receiver 1 for the extrusion molding machine comprises the inner bushing 3 having the non-circular hole 2 formed of plural portions in some cases and having the curvilinear chamfered parts 34, 34' on the short sides of the cross-section and at least another portions which are arranged nearly concentrically therewith and are coupled to the inner bushing 3 by the shrinkage fit. As a result, the effective life and reliability of the receiver 1 may be improved.
