Abstract
An injection apparatus includes a plunger, an injection sleeve, a sleeve frame, and a rotational-linear motion transmission mechanism. The plunger is supported at a substantially central portion of a supporting frame. The injection sleeve is provided to be movable forward/backward with respect to the supporting frame and receives a distal end portion of the plunger such that the distal end portion can move forward/backward. The sleeve frame supports the injection sleeve. The rotational-linear motion transmission mechanism is arranged between a motor and the supporting frame and converts a rotational motion into a linear motion.
