Title:
DISSIMILAR MATERIAL COUPLING STRUCTURE AND METHOD FOR MANUFACTURING DISSIMILAR MATERIAL COUPLING STRUCTURE
Document Type and Number:
Japanese Patent JP2023047197
Kind Code:
A
Abstract:
To easily secure coupling strength when a metal member and a resin member are coupled to each other by plastic flow.SOLUTION: A dissimilar coupling structure is for coupling a metal member and a resin member, wherein a fitting hole to which the other is fit is formed in one of the metal member and the resin member, a resin step part which escapes in the radial direction from the inner peripheral surface of the fitting hole and is recessed in the axial direction of the fitting hole is formed in the resin member, and the metal member has a plastic flow part for engaging the resin step part.SELECTED DRAWING: Figure 3
