FASTENING STRUCTURE OF RESIN PRODUCT

摘要

PROBLEM TO BE SOLVED: To stably retain axial force (fastening force) for fastening without having to decrease due to heat creep of a resin product. SOLUTION: There is provided a conical seat part 13a, having a first given angle gradually nosing toward a cylindrical part 13b side with respect to a plane orthgonally intersecting the shaft center of a nut 13 and the axial length of a second given width B wider than a first given width A. Pressing the conical seat part 13a against the stepped part 11a of a resin product 11 elastically compresses the resin product 11 by the first given width A.
