Abstract: A fluid pressure cylinder includes a cylinder tube, a piston rod, and a displacement sensor. A bottom portion of the cylinder tube has: a pin hole formed in a direction orthogonal to a center axis; and a through hole penetrating the bottom portion through the pin hole. The displacement sensor has: a sensor body disposed on inner side of the pin hole in the through hole; a sensor rod provided so as to extend from the sensor body; and an annular magnet relatively movable with respect to the sensor rod. The through hole has: a reduced-diameter portion; and a female screw portion that has a female screw formed on an inner circumference of the female screw portion. The sensor body is fixed by being pressed by a plug that is screwed into the female screw portion and by being engaged with the reduced-diameter portion.
