<p>A plurality of electromagnetic valves are mounted on a manifold base, a single top cover that covers the plurality of electromagnetic valves as a whole is mounted, the top cover is screwed into the manifold base in a state in which a positioning pin on a lower end of a peripheral wall is fitted into a small hole in the manifold base, a reinforcing rib is formed on an inner face of a top plate of the top cover, the rib is arranged so that the rib is brought into contact with the upper faces of the electromagnetic valves all the time or is brought into contact with the electromagnetic valves when the top cover is elastically deformed by a pressing force from the outside acting on the top cover.</p> |
