Flow path structure

Abstract

A flow path structure includes a first member, a second member that defines, together with the first member, first and second flow paths adjacent to each other through which cooling water for cooling an engine flows, a single face seal member; and a single shaft seal member. The first member includes a first defining portion that partially defines the first flow path and a second defining portion that partially defines the second flow path. The second member includes a third defining portion that partially defines the first flow path and a fourth defining portion that partially defines the second flow path. The single face seal member is disposed between the first and third defining portions. The second and fourth defining portions are fitted to each other. The single shaft seal member is disposed between the second and fourth defining portions.
