A connection cable is connected to the centralized connector from a program controller or the like, and each solenoid valve of the solenoid valve manifold is driven. As the centralized connector, a D-sub connector and a flat cable connector are used.

When installing a solenoid valve manifold in various apparatuses, the installation state such as the position and orientation of the manifold varies. Therefore, the connection direction in which the connection cable can be connected to the solenoid valve manifold without any trouble differs depending on the installation state of the solenoid valve manifold, and the direction of the centralized connector is required to be in the connection direction.

Then, due to this change, the orientation of the centralized connector of the installed solenoid valve manifold may become inappropriate. In this case, in order for the centralized connector to have an appropriate orientation, the orientation of the centralized connector has to be changed for each solenoid valve manifold. As a result, the man-hour and cost required for the change have been unnecessarily generated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to rotate a housing provided with a centralized wiring section to change the direction of the centralized wiring section. Is to provide.
