Abstract
In an injection apparatus, a movable unit includes a ball screw including a moving block and a screw shaft. The moving block moves in a predetermined direction and is joined to an injection plunger. The screw shaft rotates to move the moving block. The screw shaft and the injection plunger are disposed side by side in a direction orthogonal to the predetermined direction. A fixing unit includes a first portion for holding a rear end part of the screw shaft, a second portion for holding a front end part of the screw shaft, and a third portion for holding the injection cylinder. The moving block is provided between the first portion and the second portion. The third portion is provided to be pressed by the injection cylinder when the injection plunger presses the resin.
