Document Type and Number:
Japanese Patent JP3553290
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To fix an internal thread member without supporting it by hand, so that an external thread member can be easily screwed to this internal thread member.
SOLUTION: A coming-off preventing cap C1 integrally having a nut holding part fitting a nut N and a bolt hole insertion part 1 is used, and, in this nut holding part, after the nut is fitted and fixed, the bolt hole insertion part 1 in an opposite side is inserted to an inner circumferential surface 12 of a bolt hole 11. As a result, the nut N is concentrically fixedly held to an opening part of the bolt hole 11 through the coming-off preventing cap C1, and, even without supporting the nut N by one hand, a bolt nut can be screwed.
