<p>An injection device (43) capable of increasing an efficiency, reducing a size, and increasing the durability of an injection member, comprising the injection member disposed in a cylinder member movably in forward and backward directions, a linear motor device (49) driven to move forward the injection member, a metering member rotatably disposed in the cylinder member, and a metering drive means for rotating the metering member, whereby, since the injection member can be directly moved forward in an injection process by driving the linear motor device (49) for injection operation, an energy loss can be prevented from being produced and thus the efficiency of the injection device (43) can be increased.</p> |
