Abstract
【解決手段】ポンプ装置10には、モータケース12とポンプケース14とを離間する方向に変位可能に固定する固定構造82と、モータケース12とポンプケース14との間にポンプ室50の内圧が所定値以上となったときにポンプ室50内の流体を外部に逃がす逃がし構造70と、が備えられている。従って、ポンプ装置10の使用雰囲気が水溶液の凍結温度以下になって、ポンプ室50内の水溶液の一部が凍結して体積膨張した場合でも、固定構造82によりモータケース12とポンプケース14とが離間する方向に変位されてポンプ室50の体積が増加されると共に、逃がし構造70によりポンプ室50内の水溶液が外部に排出されるので、ポンプ室50の内圧の異常上昇を抑制できる。
