SEAL STRUCTURE, GAS SENSOR AND GAS DETECTOR

摘要

PROBLEM TO BE SOLVED: To provide a seal structure that has no risk of causing a crack or the like on the gasket even if a gasket undergoes high temperature, and that prevents transpiration of water from a water tank.

SOLUTION: A seal structure comprises a metal plate on the outer peripheral side which is placed so that a metal plate on the inner peripheral side is surrounded; and gasket which is made of thermoplastic elastomer or synthetic rubber and placed between the metal plates. The metal plate on the outer peripheral side is caulked to the metal plate on the inner peripheral side. The gasket transforms and fixes the metal plate on the outer peripheral side and the metal plate on the inner peripheral side and electrically isolates between the metal plates and seals with air-tightness and fluid-tightness.
