Summary:In a flow path forming structure, axial runout of a shaft relative to a central axis generated when the shaft is inserted into the flow path is suppressed. This structure includes a flow path along which a fluid passes, and a shaft body that is inserted into the flow path. An upstream side of the shaft body and an inner circumferential surface of the flow path have a plurality of contact positions at different phases, and a downstream side of the shaft body and an inner circumferential surface of the flow path have a plurality of contact positions at different phases. The fluid flows through gaps between the shaft body and the inner circumferential surface. The contact positions on one of the upstream and downstream sides are at different phases from all of the contact positions on the other one of the upstream and downstream sides.
