Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an injection apparatus having excellent controllability and maintainability in a small size and a light weight with which a plunger is driven with a simple driving mechanism. SOLUTION: Regarding the hybrid high speed injection apparatus having excellent controllability, in an injection apparatus where molten metal is filled up into a cavity in a die by driving a plunger, the rear part of a hydraulic cylinder with a built-in plunger rod controlled by a hydraulic control mechanism is provided with a piston rod controlled by an advancing/retreating control mechanism.
