Abstract

　簡易な構成で密封対象液体の漏れを検出することを可能とする。 　密封構造Ｓは、第１密封領域Ｍ１に密封された密封対象液体が第２密封領域側Ｍ２に漏れるのを防止する第１環状シール１１０と、この第１環状シール１１０に連結され、かつ、第２密封領域Ｍ２に密封された密封対象流体が第１密封領域側Ｍ１に漏れるのを防止する第２環状シール１２０とを備える密封装置１００と、第１環状シール１１０と第２環状シール１２０との間の空間領域Ｋに漏れてきた密封対象液体を検出するセンサ４００と、センサ４００によって検出される信号の処理を行う処理装置７００と、センサ４００と処理装置７００とを電気的に接続する電線６００と、電線６００が通る通路であって、大気側からセンサ４００が設けられた位置に至る通路を形成する管５００と、を備えることを特徴とする。
