A gas pressure inspecting device of an air bag portion of a bag with an air bag

摘要

A gas pressure testing device, which is for checking pressure of gas inside the gas compartment portion of a bag, including: a pressing member (31) disposed on one side of the bag, a receiving member (38) positioned on another side of the bag, and a movable support member (39) having thereon the pressing member and a distance sensor (32). The pressing member being kept urged toward the gas compartment portion by air cylinder (44) is moved toward the bag so that the gas compartment portion is sandwiched by the pressing member and the receiving member. The distance sensor measures the distance (D) at such time to the pressing member and sends a distance signal to a control unit (37). Based on the distance signal, the control unit determines whether or not the gas pressure in the gas compartment portion is within a preset range.
