Fluid pressure cylinder

A fluid pressure cylinder comprising:

• a body having a rectangular parallelepiped shape with a cylinder hole;
• a piston movably accommodated in the cylinder hole;
• and
• a piston rod secured to the piston, wherein:
• when viewed in section orthogonal to an extension direction of the cylinder hole, the cylinder hole has a polygonal shape including inner circumferential surfaces parallel to a plurality of surfaces constituting the body;
• the piston has a polygonal outer edge having a shape corresponding to a shape of the cylinder hole accommodating the piston and partitions the cylinder hole into a head-side cylinder chamber and a rod-side cylinder chamber;
• the body is cut off so that one surface of the plurality of surfaces constituting the body has a stepped shape, and a solenoid valve configured to switch between supply of pressurized fluid to the headside cylinder chamber or the rod-side cylinder chamber and discharge of the pressurized fluid from the head-side cylinder chamber or the rodside cylinder chamber is disposed in a space formed by cutting off the body;
• and
• the solenoid valve is disposed inside a virtual outer shape defined by most-protruding faces in the respective surfaces.
