PROBLEM TO BE SOLVED: To provide an injection apparatus excellent in the controllability and the maintainability in a small size and a light weight with which a plunger is driven with a simple driving mechanism. SOLUTION: In this hybrid injection apparatus, molten metal is filled up into a cavity 5 in a die by driving the plunger. The apparatus excellent in the controllability is provided with an advancing/retreating control mechanism 20 for driving a hydraulic control mechanism in the advancing and retreating direction of the plunger, in the hydraulic control mechanism 10 connected with the plunger.
