  • reference numeral 67 denotes a flexible push-pull cable configured to connect the valve body 55 and the operating lever 33 to each other. Accordingly, when the valve rod 31 is shifted in a rightward direction (arrow direction in FIG. 2), the valve body 55 is pulled in a downward direction against the force of the compression spring 65 by the action of the control lever 33. In contrast to this, when the control lever 33 is released, the valve body 55 is pushed up again by the tensioning force of the compression spring 65. It follows from this that the connection is interrupted by the elastic tube 54. At this time, the valve rod 31 is shifted in a left direction by a compression spring (return spring) 325a of the check valve 325.
  • a compression spring return spring
  • Reference numeral 341 denotes a safety valve which is arranged on the upper section of the valve chamber 23 in the base section 11. This safety valve 341 is designed to prevent the gas pressure in the valve chamber 23 from becoming unnecessarily high.
  • a rear portion of the cartridge P filled with the viscous agent is fitted into an opening 43 a through a sealing member S.
  • the sealing member S is formed of an elastic material such as rubber or the like, and has a cylindrical member 246 which has an outer flange 242 at its front end and an inward curved member 244 at its rear peripheral portion, each formed integrally therewith.

  • valve body 55 is then pushed in an upward direction by the tensioning force of the compression spring 65. It follows that the connection through the elastic tube 54 is in turn interrupted by the moving pin 59 and the fixed pin 63. At the same time, the valve rod 31 is shifted in a left direction by the compression spring 325a to close the shutoff valve 325. As a result, the supply of pressurized carbon dioxide gas to the gas chamber 43 is stopped.
  • Reference numerals 481 and 483 denote support sections each having a through hole 485.
  • the support sections 481 and 483 are arranged at the front lower end of the base body 11.
  • the two support sections 481 and 483 are separated from one another by a certain distance.
