Title:
管状部材の結合装置を用いた異材接合方法及び異材接合用補助部材付き管状部材の製造方法
Document Type and Number:
Japanese Patent JP7473615
Kind Code:
B2
Abstract:
This coupling device for a tubular member is provided with: a base stand for holding an inner member and an outer member in a state in which the outer member is disposed around the inner member; a plurality of pressing members that are supported by the base stand in a movable manner in the radial direction of the inner member and the outer member and have a protruding part on the tip thereof; a pressing member that make contact with the final end of the pressing member and that can press the pressing member radially inward; and a drive mechanism that drives any one among the base stand and the pressing member in a direction perpendicular to the movement direction of the pressing member so that the one member moves relative to the other. The inner member and the outer member are caulked and coupled by driving, by the drive mechanism, any one among the base stand and the pressing member and displacing the pressing member radially inward to thereby expand, radially inward, a portion of a peripheral wall of the outer member by the protruding part.
