    Abstract: An injection member of a molding machine is provided which can shorten the molding cycle and maintenance time, and prevent occurrence of galling between a cylinder member and an injection member. The injection member of the molding machine includes a supply section (P1) to which a molding material is supplied via a molding material supply port of the cylinder member, a compression section (P2) for melting and compressing the molding material supplied from the supply section (P1), and a metering section (P3) for metering the molding material supplied from the compression section (P2). The supply section (P1) has a pressure adjustment changeover point (q1) shifted rearward from its front end by a predetermined distance, and is divided at the pressure adjustment changeover point (q1). The pressure of the molding material is gradually reduced in a pressure gradual reduction area (AR1) from the rear end of the supply section (P1) to the pressure adjustment changeover point (q1).
