Electromagnetic valve manifold

An electromagnetic valve manifold, comprising:

• an electromagnetic valve;
• and
• a manifold base on which the electromagnetic valve is mounted, the manifold base including a supply passage, an output passage, and a discharge passage, wherein
• the electromagnetic valve includes:
• a casing including a valve hole;
• a valve member that is movably accommodated in the valve hole;
• and
• a supply port, an output port, and a discharge port that are formed in the casing and respectively connected to the valve hole,
• the supply port is connected to the supply passage,
• the output port is connected to the output passage,
• the discharge port is connected to the discharge passage,
• the output passage is configured such that a fluid flowing through the output passage drives a fluid pressure device connected to the output passage,
• the electromagnetic valve includes a manual shaft,
• the manual shaft is configured to be manually operated to be switched between a first switching position, in which the manual shaft allows the valve member to move relative to the valve hole, and a second switching position, in which the manual shaft restricts movement of the valve member relative to the valve hole, thereby maintaining a pressure of a fluid between the output passage and the fluid pressure device,
• the manual shaft includes a projection that is projected into and retracted from the valve hole,
• the valve member includes at least one recess in an outer surface of the valve member, and
• the manual shaft is configured such that, in a state in which the manual shaft is located in the second switching position, the projection is projected into the valve hole and engaged with the recess, so as to restrict movement of the valve member relative to the valve hole.
