て達成される。According to the present invention, there is provided, in accordance with the present invention, a substantially cylindrical retainer fixed to a member to be fastened, and having a substantially cylindrical retainer around the fastening axis. A first screw-type fastening member that fits into the retainer so as to be relatively unrotatable; and a second screw-type screw member that is screwed with the first screw-type fastening member and clamps the member to be fastened between at least the retainer. This is achieved by a screw-type fastening device, comprising: a fastening member, wherein the first screw-type fastening member has a flange that abuts on the retainer on a side opposite to the member to be fastened.

したりする虞れが低減される。According to the first aspect of the present invention, the first screw-type fastening member is fitted to the retainer such that it cannot rotate relatively around the fastening axis, and the first screw-type fastening member is opposite to the member to be fastened. Has a flange portion that abuts the retainer on the side of the nut. Therefore, even if the nut and the retainer loosen over time due to a difference in the coefficient of thermal expansion of the constituent materials of the nut and the retainer, the nut can be retained. And the bolt does not rotate relative to the bolt, and the compressive stress due to the fastening is reliably transmitted from the flange to the member to be fastened via the retainer, thereby reducing the pressure acting on the member to be fastened. The possibility that the fastening state of the fastening member deteriorates relatively early or that the member to be fastened is reduced is reduced.

れを効果的に且つ確実に低減することができる。As is apparent from the above description, according to the structure of the first aspect of the present invention, the first screw-type fastening member is fitted to the retainer so as to be relatively non-rotatable about the fastening axis. Since the one screw-type fastening member has a flange portion that comes into contact with the retainer on the side opposite to the member to be fastened, there is a difference between the nut and the retainer due to a difference in the coefficient of thermal expansion of the constituent materials of the nut and the retainer. Even if the nut is loosened over time, the nut does not rotate relative to the retainer and the bolt, and the compressive stress due to fastening is transmitted to the member to be fastened via the retainer more reliably from the flange. The pressure acting on the member to be fastened is reduced, so that the risk of the fastening state of the member being fastened or the member being damaged being damaged relatively quickly can be effectively and reliably reduced.

る。Further, since the first screw-type fastening member does not rotate relative to the retainer, it is not necessary to fix the first screw-type fastening member with a tool so as not to rotate even when the fastening needs to be released. The fastening can be easily and reliably released simply by rotating the second screw-type fastening member.

Therefore, the first screw-type fastening member can be easily and reliably fixed to the member to be fastened via the retainer, and the possibility that the coated fastening member is damaged can be further reduced.
