Abstract: A body comprising a nut retaining apparatus mounted thereon for fastening a bolt to the body. The bolt is inserted into a bolt insertion hole at an end surface of the body from a direction inclined with respect to a direction tangent to the body. The nut retaining apparatus comprises a nut retainer and a nut holder, the nut retainer positioned at an insertion end of the bolt insertion hole in the body and against which a nut member having a threaded hole abuts, and the nut holder mounted on the body for supporting the nut member in the inclined direction. The nut member is retained and supported in the inclined direction at a position between the nut retainer and nut holder and continuous with the bolt insertion hole.

Abstract: In a nut retaining apparatus for holding a nut 282 in a connection body 28 in an inclined direction, the nut retaining apparatus comprises a nut retainer 283 which is provided on an insertion end of the bolt insertion hole 28h in the connection body 28, and the nut holder 281 supports the nut 282 and is mounted on the connection body 28, thereby retaining the nut 282 at a position of the nut retainer 283. Thus, it is possible to provide a nut retaining apparatus and a nut holder capable of effectively preventing the producing procedure from being complicated, and preventing the producing cost from being increased.
