ABSTRACT:
A manifold which are widely applicable for oil pressure, water pressure or pneumatic pressure equipments is manufactured, instead of grinding or boring machining process on an ingot, by forming a fluid passage with a pipe group and casting this pipe group in a casting member or supporting the same with a surface plate or a base plate which may double as a surface plate, thereby achieving a light-weight manifold of a high precision and of a simple structure.
