Viscous material application apparatus

A viscous material application apparatus comprising:

• a main body having a pressurized chamber for storing a viscous material, the pressurized chamber connecting through to a discharge port;
• a viscous material supply device for transferring said viscous material under pressure to said pressurized chamber;
• and
• a discharge pressure regulating device for regulating a discharge pressure of said viscous material by increasing and decreasing a capacity of said pressurized chamber when said viscous material inside said pressurized chamber is pressurized and discharged,
• wherein the discharge pressure regulating device includes a cylinder having a piston and a diaphragm which is engaged by said piston and which transforms under influence of said piston and increases and decreases capacity inside said pressurized chamber.
