Abstract
A fluid pressure cylinder apparatus comprises a cylinder tube integrally connected between a head cover and a rod cover; a piston internally installed in the cylinder tube, for making displacement in accordance with an action of a pressure fluid supplied into the cylinder tube; and a piston rod connected to the piston; wherein a pair of first dust-removing members are installed on an outer circumferential surface of the piston with a piston packing intervening therebetween; and a second dust-removing member and a third dust-removing member are installed to an inner circumferential surface of a support section of the rod cover for the piston rod with a rod packing intervening therebetween.
