MOORING DEVICE FOR SPAR BUOY

To provide a mooring device for a spar buoy whose durability is improved by further reducing a load applied to a shaft part in a mooring device due to the swing of the spar buoy and preventing mud and sand from entering the periphery of the shaft part of the mooring device.SOLUTION: A mooring device for a spar buoy has a pair of joint members 10, 10 fixed to a lower end of a post body 2 and an upper end of a sinker 3, respectively, shaft members 20, 20 that pivotally attach the joint members 10, 10 so as to be freely rotatable, a piece member 30 that is interposed between both joint members 10, 10 and rotatably bears and connects the shaft members 20, 20, and a lid part 14 that closes both ends of pivotal attachment parts 13, which are formed by opening holes near tips of support parts 12, 12 of the joint members 10, 10, in a state of inserting the shaft members 20 into the pivotal attachment parts 13.SELECTED DRAWING: Figure 1 【課題】 スパーブイの揺動による係留装置内の軸部に掛かる負荷をより一層低減するとともに、係留装置の軸部の周囲への泥砂の侵入を防止することで、耐久性を向上させたスパーブイ用係留装置を提供する。【解決手段】 標柱体２の下端及び沈錘３の上端にそれぞれ固定する一対の継手部材１０、１０と、継手部材１０、１０を回動自在に軸着する軸部材２０、２０と、両継手部材１０、１０間に介在するとともに軸部材２０、２０を回動自在に軸受して連結するコマ部材３０と、継手部材１０、１０の支持部１２、１２の先端付近に開孔して形成された軸着部１３に軸部材２０を挿入した状態において軸着部１３の両端を閉塞する蓋部１４と、を有するものである。【選択図】 図１
