PROBLEM TO BE SOLVED: To provide a structure for mounting a plug member which can suppress stress from being concentrated in a specific region in a structure for mounting a plug member in which the plug member is welded to a structural member or the like formed with a through hole, and to which stress is exerted.SOLUTION: A structure for mounting a plug member includes: a partition wall 10 defining an interior space to which a fluid with a higher temperature and a higher pressure than those on the outside is held or circulated; a plug member 20 inserted into a through hole formed at the partition wall 10; and a welding part 30 where an outer surface of the partition wall 10 and the plug member 20 are jointed together. The partition wall 10 has a tapered surface 40 gradually projecting outward as proceeding to a center of the through hole, around the through hole. The welding part 30 is provided so as to be smoothly connected to the tapered surface 40 of the partition wall 10. |
