Title:
ANNULAR MEMBER, FITTING MEMBER, JOINED MEMBER, METHOD FOR MANUFACTURING JOINED MEMBER, AND DEVICE FOR MANUFACTURING JOINED MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/209796
Kind Code:
A1
Abstract:
This annular member is provided with an annular contact surface on an annular inner wall of a boundary with an annular space formed in an annular internal part thereof. In the fitting member, a fitting contact surface contacting one part of the annular member when inserted into the annular space is provided on a side surface in the vicinity of a distal end. When the fitting contact surface is brought into contact with the annular contact surface, a gap between receiving surface sides and a gap between distal end sides occur. The joined member is obtained by joining the annular member and the fitting member. The method for manufacturing the joined member provides the annular member and the fitting member, which are brought into contact, supplied with electric current while being pressed, and plastically deformed to be joined together. The device for manufacturing the joined member comprises electrodes sandwiching the annular member and the fitting member therebetween, a current generator, a movement device which moves both electrodes so as to approach each other, and a control device.
