Summary:PROBLEM TO BE SOLVED: To provide a wire tensioning device in which a tensioned wire rod can easily be tensed in course wire such as canoe competition, and the handling is easy in the conveyance and setting or in the storage.SOLUTION: A wire tensioning device 10 is provided in which a shaft member 13a is suspended from a float 11 floating on a water surface. A worm gear 15 is provided in the lower end of this shaft member 13a. Course wire W1 is connected to the worm gear 15. The worm gear 15 includes a worm coaxially provided with the shaft member 13a and a worm wheel engaged with the worm. A reel part 16 is coaxially provided in the worm wheel, and a tension wire rod 17 connected to an anchor 12 is wound up. A worker operates a handle part 14 provided on an upper end of the shaft member 13a projecting from the float 11 to thereby rotate axially the worm, and winds up the tension wire rod 17 to the reel part 16 to thereby make the course wire W1 be tense.SELECTED DRAWING: Figure 1 【課題】カヌー競技などののコースワイヤにおいて、被緊張線材を容易に緊張させることができ、運搬時や設置時、保管時など、取り扱いが容易なワイヤ張力調整装置を提供する。【解決手段】ワイヤ張力調整装置10は、水面に浮上するフロート11から軸部材13aが垂下している。この軸部材13aの下端には、ウォームギア15が設けられている。ウォームギア15には、コースワイヤW1が連結されている。ウォームギア15は、軸部材13aと同軸に設けられたウォームとウォームと噛み合うウォームホイールとを備えている。ウォームホイールには、同軸にリール部16が設けられており、アンカー12に連結された緊張用線材17が巻かれている。作業者は、フロート11から突出した軸部材13aの上端に設けられたハンドル部14を操作することでウォームを軸回転させ、リール部16に緊張用線材17を巻き取ることでコースワイヤW1を緊張させる。【選択図】図1
