Ventilation component
A ventilation component includes a valve body portion, a shaft portion, a ventilation path, and a gas-permeable membrane. The shaft portion extends in a normal direction of the valve body portion. The shaft portion supports the valve body portion. The ventilation path extends through the shaft porti...

| description | A ventilation component includes a valve body portion, a shaft portion, a ventilation path, and a gas-permeable membrane. The shaft portion extends in a normal direction of the valve body portion. The shaft portion supports the valve body portion. The ventilation path extends through the shaft portion. The gas-permeable membrane closes the ventilation path. In a state where the ventilation component is fixed to a housing, a flow of gas passing through a peripheral opening is blocked by the valve body portion, and ventilation occurs between an inner space and an external space via the gas-permeable membrane. When a pressure difference obtained by subtracting a pressure of the external space from a pressure of the inner space is equal to or higher than a predetermined value, the valve body portion elastically deforms to be away from an outer surface to release the pressure of the inner space. |
