Title:
VALVE STRUCTURE, OPENING-SEALING MEMBER, POWER STORAGE DEVICE, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/181693
Kind Code:
A1
Abstract:
The present invention comprises: a tube body (tube 16) that is provided with a shaft (18); and a first valve body (11) that adheres to the shaft and thereby seals an opening (22) of the tube body, such that when a gas that has entered inside the tube body causes the pressure (P) inside the tube body to rise to or above a threshold value (Pth), the valve body separates from the shaft and the gas is released to the outside from the tube body. The valve body comprises a closing section (40) that receives the pressure (P) of the gas inside the tube body, and the pressure received by this closing section (40) serves as a valve-opening force. The foregoing configuration improves the emission characteristics of a gas which fills the interior of a case, and allows for an enhanced pressure regulating function.
