Abstract

An injection apparatus wherein a pressure accumulation part is connected to an operating chamber of an injection cylinder. A control unit which controls the speed at which the injection cylinder moves is connected to a rod of the injection cylinder. The control unit comprises: a rotating shaft that follows the movement of the rod and is capable of moving in the same direction as the rod; a conversion mechanism that converts the linear motion of the rod into the rotational motion of the rotating shaft; and a rotating member that is coupled to the rotating shaft. The control unit comprises: a resistance generating member that generates a frictional resistance by coming into sliding contact with the rotating member; an actuating member that is moved by an electric drive source; and a movement mechanism that follows the movement of the actuating member and moves the resistance generating member to the rotating member.
