Title:
COUPLING
Document Type and Number:
WIPO Patent Application WO/2017/061587
Kind Code:
A1
Abstract:
This coupling is characterized by comprising: a first cushioning member made from a wire that is helical in planar view; a second cushioning member that is substantially annular, flat plate-shaped, and bendable in the thickness direction; a collar member that comprises a cylinder part surrounded by the first cushioning member and the second cushioning member, a first flange facing the inner diameter side of the first cushioning member, and a second flange facing the inner diameter side of the second cushioning member; and a coupling member that comprises a first holding part that holds the outer diameter side of the first cushioning member and the second cushioning member, a second holding part that holds a shielding body, and a coupling member base. The coupling is further characterized in that a gap allowing the second cushioning member to move in the radial direction is formed between the second cushioning member and the cylinder part, and the inner diameter side of the first cushioning member and the second cushioning member is interposed between the first flange and the second flange so as to allow said movement of the second cushioning member in the radial direction. The present invention makes it possible to provide a coupling in which usage-induced deformations of the cushioning member made from a helical wire are reduced, and midway portions do not pop out.
