PURPOSE:To smoothly inject a viscous agent such as a sealant without rendering pressurized gas futile, by providing an extraction control valve to an emitting port and allowing said valve to cooperate with the opening and closing valve of pressurized gas through a flexible cable while imparting the control and safe function of gas pressure. CONSTITUTION:When an operation lever 29 is pulled to the direction shown by the arrow against compression springs 25a, 71, a valve lever 27 is slid to the right direction and an opening and closing valve 25 is opened to flow pressurized carbon dioxide into a gas chamber 39 to press the bottom surface of a viscous agent packed cylinder P. At the same time, a flexible cable 73 is pulled to pull down the valve body 61 of an injection control valve 53 and, because a closed elastic pipe 59 is communicated, the viscous agent of the viscous agent packed cylinder P is injected from a nozzle 55. When injection is stopped, the pulling of the operation lever 29 is released. Herein, the gas pressure of the gas chamber 39 is regulated by determining the spring force of the compression spring by rotating a control nut member 103 and a safety valve 41 is operated when said gas pressure reaches or exceeds the predetermined pressure.
