CRIMP STRUCTURE, CRIMPING METHOD, AND ELECTRONIC DEVICE

摘要

Provided is a crimp structure in which an inner member and an outer member that is arranged outside the inner member are joined to each other. The inner member includes: an insertion portion having a columnar surface-like outer circumferential surface; and a recessed portion provided in the outer circumferential surface. The outer member includes: a cylindrical portion that forms an opening into which the insertion portion is inserted; a reduced-diameter portion that is formed in the cylindrical portion, and has a plastically deformed shape such that a diameter of the cylindrical portion is reduced annularly inward in a radial direction; and a protruding portion that has a plastically deformed shape such that a part, in a circumferential direction, of the reduced-diameter portion has entered the recessed portion. Relative rotation of the inner member and the outer member can be suppressed.

1. A crimp structure in which an inner member and an outer member that is arranged outside the inner member are joined to each other,
wherein the inner member includes: an insertion portion that has a columnar surface-like outer circumferential surface, and a recessed portion that is provided in the outer circumferential surface, the outer member includes: a cylindrical portion that forms an opening into which the insertion portion is inserted; a reduced-diameter portion that is formed on the cylindrical portion, and has a plastically deformed shape such that a diameter of the cylindrical portion is reduced annularly inward in a radial direction; and a protruding portion that has a plastically deformed shape such that a part, in a circumferential direction, of the reduced-diameter portion has entered the recessed portion.
