摘要: An object is to reduce the axial dimension of an injection apparatus (31), facilitate the work of removing and inserting a screw (20), and improve the quality of molded products. The injection apparatus (31) comprises a heating cylinder (17), a screw (20), and a drive apparatus. 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 ε, 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
