(57) [Summary] [PROBLEMS] To effectively suppress both in-plane vibration and out-of-plane vibration. SOLUTION: A yoke portion 5 of a gut tension portion 1 sandwiched between left and right sides of a throat portion 2 is made larger than a weight per unit length other than the yoke portion of the gut tension portion. Alternatively, the cross-sectional circumference of the yoke portion is made larger than the cross-sectional circumference of the gut-tightened portion other than the yoke portion and the throat portion. The yoke has a specific gravity of 0.3 to 1.0 g / cm 3 inside a hollow outer peripheral frame made of fiber reinforced resin. Is filled. |
