2. Description of the Related Art For example, when driving an actuator such as an air cylinder with a solenoid valve, it is necessary to connect these solenoid valve and the actuator with a pipe. When driving a plurality of actuators, a plurality of solenoid valves corresponding to them are used, and thus the number of pipes naturally increases. When connecting the solenoid valve and the actuator with pipes in this way, usually, the solenoid valve and the actuator are fixed in place respectively, and then pipe fittings are attached to those ports to connect the pipes. However, since it is necessary to carry out the steps from installation of the pipe joint to connection of the pipes separately and in sequence, the number of man-hours increases and the work is very troublesome.

Such a problem is not limited to the case where a plurality of solenoid valves are collectively used as described above.
This is a common problem when connecting piping to general fluid pressure equipment having a plurality of ports.
