<P>PROBLEM TO BE SOLVED: To provide a fluid pressure cylinder capable of preventing a sealing means, which is used to seal an opening end of a shaft hole formed in a piston rod, from coming down to the inside of a cylinder tube, and a method of manufacturing the same. <P>SOLUTION: A head-side passage 11 for connecting a head-side chamber 2 to a working fluid pressure source is defined by a head-side shaft hole 12 which is elongated in the axial direction of a piston rod 30. The head-side shaft hole 12 includes the opening end 12A which is opened in a part protruding from the cylinder tube 10 of the piston rod 30, and a tip 12B which is formed inside the piston rod 30. The sealing means (plug 17) for sealing the opening end 12A of the head-side shaft hole 12 is provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
