The present invention relates to a cover plate-fastened actuator in which a foreign substance inflow space is blocked. According to the present invention, an accurate horizontal-vertical interworking motion can be performed while an accurate operation can be performed as any foreign substance or operation fragment is blocked from flowing inside from the outside. According to the present invention, a horizontally penetrating cover through-hole is formed in a moving block which directly performs a horizontal interworking of the actuator, and a cover panel is inserted into the cover through-hole so that an open hole of an actuator base frame is covered and a phenomenon in which a foreign substance flows inside from the outside is fundamentally blocked by the cover panel. In addition, a vertical cover plate portion which forms an open portion of the base frame covers a vertical blocking portion of the cover panel while ensuring a higher-level position so that even the foreign substance which could horizontally flow into the inflow space can be completely blocked from flowing inside. |
