Title:
FASTENING STRUCTURE AND FASTENING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/136878
Kind Code:
A1
Abstract:
Provided are a fastening structure and a fastening method that are able to suppress the occurrence of defects arising when using a conventional disc spring or ring in the case of attaching a member in a device at a predetermined load. In the fastening structure (100), a nut (103) presses a disc (102) against the support section (101B) of a hub (101) with a disc spring (110) therebetween by means of the fastening thereof, for example. The disc spring (110) imparts a predetermined load to the disc (102). A flat surface (113B) that is inclined with respect to an inclined surface (113A) is formed at the outer peripheral portion of a concavity (113) of the main body (111) of the disc spring (110). The flat surface (113B) can contact the surface of the disc (102) when an impact arises. The amount of deflection of the disc spring (110) is, as indicated in fig. 2(B), set in a manner so that when the fastening of the nut (103) is complete, the support point (P) of the concavity (113) of the disc spring (110) is positioned at the inner peripheral portion (113C) of the flat surface (113B) or at the inner peripheral side thereof.
