PROBLEM TO BE SOLVED: To provide a metal seal assembling structure capable of easily assembling a seal at a designated position without any influence of an assembling direction of a metal seal. SOLUTION: An assembling structure of a circular metal seal S is mounted on a storing recessed portion 6 having a first flat surface 1 and is wholly interposed between the first flat surface 1 and a second flat surface 2 parallel to the first flat surface 1. The metal seal S has a first contact portion 11 with a cross-sectioned convex shape approached to an outer periphery, which is brought into contact with the first flat surface 1 and a second contact portion 12 with a cross-sectioned convex shape approached to an inner periphery, which is brought into contact with the second flat surface 2. A drop out prevention member 3 capable of preventing the metal seal S from coming off the recessed portion 6 by coming into contact with the metal seal S is provided. COPYRIGHT: (C)2005,JPO&NCIPI
