Abstract
There is provided a sealing structure in which sealing is performed by covering a fluid passage of a housing using a displacement member that is displaceable according to change in pressure. The displacement member includes a first projecting section which is a sealing section in an outer peripheral section, and a second projecting section which is formed in an inner peripheral section rather than the first projecting section, and the housing is capable of fixing the displacement member in a state in which the first projecting section is compressed, and includes a depression section, in which the second projecting section is placed when the displacement member is fixed, in a position which faces the second projecting section.
