PROBLEM TO BE SOLVED: To provide a seal structure for a fluid machine reducing cost and extending a life.SOLUTION: An annular male adapter 21 disposed at one side of an annular packing 20 for gripping the packing 20 from both sides includes a V-shape cross section projection part 21a, and is manufactured from flat plate by pressing. Consequently, cost is reduced by inhibiting increase of manufacturing cost. The packing 20 is pressed by an elastic function of the V-shape cross section projection part 21a. Consequently, looseness is eliminated by applying load in the packing 20 and a life is extended. |
