PROBLEM TO BE SOLVED: To provide a cushion rubber for fishing which has excellent durability to an extent in which even excessive pulling or escaping of fish with rapid movements does not cause any problem.SOLUTION: In the cushion rubber for fishing, rubber string 3 is formed by knitting fiber 2 in a way which surrounds rubber system core material 1 as a core and swivel A is connected to both ends of the rubber string 3. The swivel A is directly connected to differentiated cylindrical shaft 5 of which side has a small hole 4 by passing the end of the rubber string 3 through the hole, and is engaged to cylindrical bearing 7 with a hole 6 on its side in a manner which allows it to turn freely in the cavity, wherein a lid body 8 provided with connection ring B is firmly inserted into the opening on the other side of the bearing 7, to form a sealed structure, and constitutes a rubber string cushion for fishing. Also, the rubber string cushion for fishing is provided with the swivel A with a ball bearing structure in which several balls 9 for the bearing are installed around the gap between inner surface 7a of one side of the bearing 7 and a joint surface 5a of the shaft which is jointed with the inner surface to rotate.COPYRIGHT: (C)2013,JPO&INPIT【課題】耐久性に優れた過剰な引っ張りや急激な変動での魚の逃げ回りでも仕掛けに支障をきたす事のない釣り用クッションゴムを提供する。【解決手段】釣り用クッションゴムにおいて、ゴム系芯材1を核にして周りを繊維2を編んで成るゴム紐3の両端子には縒り戻し具Aを結合して成るが、縒り戻し具Aは、側面に小穴4のある段付き筒状の軸体5に、ゴム紐3の端子が小穴を通して直結され、側面に穴6付きでなる筒状の軸受け7の中空内で回動自在に係合し、軸受け7の他方側面の開口部には接続リングBを具備した蓋体8が固く差し込まれて封印構成でなる縒り戻し具Aを装備した釣り用ゴム紐クッション構成にする。また、軸受け7に設けた片側面の内側壁面7aと該内側壁面に接合して回動する軸体の接合面5aの隙間周りに数個の軸受け用のボール9を配置してなるボールベアリング構成での縒り戻し具Aを装備した釣り用ゴム紐クッション構成にする。【選択図】図1
