For the purpose of obtaining a manifold for a change-over valve capable of corresponding with given situations easily and reliably even when some of piping directions of the change-over valves are different or piping directions are altered during an operation, port surfaces 21, 22 are respectively formed on a front end surface and a bottom surface of a manifold 1, output openings 23a, 23b commonly in communication with output passages 14a, 14b are respectively formed on the port surfaces 21, 22, and a port block 26 having output ports A, B in communication with the output openings 23a, 23b and a closing plate 27 for closing the output openings 23a, 23b are allowed to be selectively mounted.
