The screw (20) includes a plasticizing portion which includes a body portion (45a) and a flight (53) projectingly formed on an outer circumferential surface of the body portion (45a). An index ?, which is obtained by dividing a value obtained by adding a screw stroke S and a screw effective length L together by the screw stroke S, satisfies the relation 2.0<?<4.5. Even when the screw (20) is shortened, resin can be melted satisfactorily. Accordingly, the axial dimension of the injection apparatus (31) can be reduced.Type: GrantFiled: August 8, 2008Date of Patent: October 25, 2011Assignees: Sumitomom Heavy Industries, Ltd., Spiral Logic LimitedInventors: Hirotsugu Marumoto, Shigeru Takeuchi, Kohei Washida, Daisuke Goto, Munekatsu Kamiya
