1. An electromagnetic valve manifold, comprising:
electromagnetic valves arranged side by side in one direction, each electromagnetic valve including a supply port;
manifold bases each including a supply passage, the supply passage being configured to supply a pressure fluid to the supply port;
spacers, each spacer being displaced between one of the manifold bases and one of the electromagnetic valves; and
pressure reducing valves each including a body that has a shape of an elongated rectangular block, each pressure reducing valve being configured to reduce a pressure of the pressure fluid that flows out from one of the electromagnetic valves, wherein
the manifold bases, the spacers, and the bodies are arranged side by side in an arrangement direction of the electromagnetic valves in correspondence with the electromagnetic valves,
a width direction of each body agrees with the arrangement direction of the electromagnetic valves,
each spacer includes:
an attachment surface to which the body is attached;
a first supply connecting passage that includes a first end connected to the supply passage and a second end that opens in the attachment surface; and
a second supply connecting passage that includes a first end connected to the supply port and a second end that opens in the attachment surface, each body includes:
a primary-side passage that is connected to the first supply connecting passage;
a secondary-side passage that is connected to the second supply connecting passage;
a first surface that is located at a first end in a longitudinal direction of the body;
a second surface that is located at a second end in the longitudinal direction of the body; and
a connecting surface that connects the first surface and the second surface to each other, and extends in the longitudinal direction and the width direction,
a pressure gauge is provided on the connecting surface, the pressure gauge being configured to detect a pressure in the secondary-side passage,
a width of the body is smaller than a size in the width direction of the pressure gauge,
the pressure reducing valve is configured to reduce the pressure of the pressure fluid that flows out from the electromagnetic valve by reducing the pressure in the secondary-side passage such that the pressure detected by the pressure gauge becomes the preset pressure,
each of the primary-side passage and the secondary-side passage extends in the longitudinal direction through the body, and includes a first opening and a second opening that respectively open in the first surface and the second surface,
the pressure gauge protrudes from the connecting surface in a state of being offset toward the first surface with respect to a center in the longitudinal direction of the connecting surface, the bodies include:
one or more first bodies, the first surface of each first body being attached to the attachment surface; and
one or more second bodies, the second surface of each second body being attached to the attachment surface of one of the spacers different from the spacer to which the first body is attached, and
the first bodies and the second bodies are arranged alternately in the arrangement direction.
