5, the side surface 79 of the flange 74 on the side where the brake member 73 is mounted tends to undulate around the bolt hole 75, so that the accuracy of the runout of the side surface 79 tends to be affected, and the runout accuracy is poor. As a result, the performance of the brake member 73 and the wheel member 77 is adversely affected. Therefore, it is necessary to pay sufficient attention to the surface runout accuracy of the flange side surface 79, and the management thereof is troublesome. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the conventional structure and to provide a fastening structure capable of minimizing an influence on a side surface of a flange due to press-fitting of a bolt.

A bolt is press-fitted and fixed in an axial bolt hole formed in the flange, a member to be mounted is attached to a foot of the bolt protruding from the flange, and a nut screwed into a screw formed in a foot of the bolt. In the fastening structure in which the attached member is pressed and fixed to the side surface of the flange, the attached member comes into contact with the side surface of the flange circumferentially.
A continuous band-shaped groove is formed, and the bolt hole is formed in the groove.
It is characterized by having been formed . Further, according to the present invention, an annular or substantially annular radially outer flange is provided on the mounting member, and a plurality of bolts are press-fitted and fixed into a plurality of axial bolt holes formed in the flange, and the bolts protruding from the flange are provided. In a fastening structure in which a member to be mounted is attached to a foot portion of the bolt, and the member to be mounted is pressed and fixed to a side surface of the flange by a nut that is screwed into a screw portion formed on a foot portion of each bolt, Forming a circumferentially continuous band-shaped groove on the side surface of the flange with which the
