ABSTRACT:
A method for filling gas into a sealed cylinder device having a rod guide closing one end thereof and guiding a rod slidably therethrough comprising the steps of forming the rod guide to have a cavity consisting of a cylindrical portion to retain a seal therein and an inwardly divergent portion continuous with the cylindrical portion, displacing the seal inwardly so as to form an annular gap between the outer periphery of the seal and the wall of the divergent cavity portion, filling gas into the cylinder device through the annular gap, and displacing the rod outwardly to carry the seal therewith so as to displace the seal into the cylindrical cavity portion, whereby the seal is thereafter retained in its position due to gas pressure in the cylinder.
