Abstract

PURPOSE: To produce always constant pressing force despite use of multiple times by controlling the opening and closing of a check valve for air suction provided in a bag body by way of the elastic body which is contained in the inside and is pressed from the outside.
CONSTITUTION: When pressing force is applied from the outside to a bag body 3 having airtightness and flexibility such as synthetic resin or the like containing an elastic material 4 such as foamed resin or the like, the check valve 2 provided to the bag body 3 closes and the pressure of the air in the bag body 3 is detected with a pressure detecting switch 5. When the bag body 3 recovers together with the elastic body 4 owing to removal of the pressing force, the valve 2 opens, thus always fixed volume of air is flowed into the bag body 3, and this provides the pressing device which is capable of applying always constant pressing force despite use of multiple times.
