<p><P>PROBLEM TO BE SOLVED: To provide a coupling structure of a swing arm a valve body by which making time can be shorten, yield can be improved, and sufficient toughness can be obtained and to provide a reheat steam stop valve. <P>SOLUTION: In the coupling structure of the swing arm and the valve body in the swing valve having the swing arm 30 turnably arranged around a turning axis J0 and the valve body 20 coupled to the coupling end 30a of the swing arm, the valve body has a valve body center through-hole 21 passing through in a center axis J1 direction at the center position of the same, the swing arm has a coupling end passing through-hole 31 passing through in the turning direction of the swing arm in the coupling end with the valve body, and a highly tough fastening member fastening the valve body and the swing arm by threading the same through both holes of the valve body center passing through-hole and the coupling end of passing through-hole with the valve body and the swing arm brought into abutment with each other such that the valve body center passing through-hole and the coupling end passing through-hole overlap is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
