装置。 A permanent magnet is attached to the outer periphery of a piston fitted in a cylinder tube of a fluid pressure cylinder with the opposing directions of the magnetic poles facing the moving direction of the piston, and two magnetic resistance elements whose sensing directions are perpendicular to each other. are arranged on the same surface and connected in series, and the output power is taken out from the connection point. A sensor is mounted on the outer peripheral surface of the cylinder tube so that the sensitive direction of each of the magnetic resistance elements is in the direction of movement of the piston. A piston position detection device for a fluid pressure cylinder, characterized in that the piston position detection device is mounted on a surface of the piston that faces in the radial direction along the piston in a posture that faces parallel to and perpendicular to the moving direction of the piston.
