Zusammenfassung:	PURPOSE:To suppress the undulation of the side surface on an installed member side when a bolt is press-fitting-fixed in a bolt hole formed on the flange of the installed member. CONSTITUTION:As for a tightening structure, a radial direction flange 6 is installed on an installation member 2, and a bolt 10 is press-fitting-fixed in a bolt hole 7 in the axial direction which is formed on the flange 6, and an installed member 8 is installed at the foot part 10b of the bolt 10 projecting from the flange 6, and the installed member 8 is press-contact-fixed on the side surface 14 of the flange 6 by a nut 12 screwed with a screw part formed at the foot part 10b of the bolt 10. Accordingly, a groove part 13 including the peripheral edge is formed at the peripheral edge of the bolt hole 7 on the flange side surface 14 where the installed member 8 makes contact, and the bolt hole 7 is positioned in the groove part 13.
