Abstract
In a connected-part seal structure configured to couple a first connected part and a second connected part through a seal member, the taper angles of first and second inner pressure-contact tapered parts provided in the seal member are smaller than the taper angles of first and second inner tapered parts provided in the first and second connected parts. Thus, a pressure-contact force of first and second inside tapered pressure-contact allowances are larger as the inside tapered pressure-contact allowances are located closer to base end parts of first and second annular protrusions.
