To provide an eddy current damper capable of suppressing oscillation of a measuring instrument and making the measuring instrument face toward a desired direction, and a work vehicle comprising the eddy current damper.SOLUTION: An eddy current damper 41 comprises a rotary plate 43 composed of an electric conductor, a support member 42 rotatably supporting the rotary plate 43, and a magnet 44 provided on the support member 42. The rotary plate 43 has a device mounting part 43a for a measuring instrument. The magnet 44 is arranged oppositely to the rotary plate 43 so as to generate an eddy current on the surface of the rotary plate 43 when the rotary plate 43 is rotated, and to suppress the rotation of the rotary plate 43 in a non-contact manner.SELECTED DRAWING: Figure 3

    【課題】計測機器の揺動を抑制できるとともに、前記計測機器を所望の方向に向かせることが可能な、渦電流ダンパおよび前記渦電流ダンパを備えた作業車両を提供する。【解決手段】渦電流ダンパ41は、電気伝導体から構成された回転板43と、回転板43を回転自在に支持する支持部材42と、支持部材42に設けられた磁石44と、を備える。回転板43は、計測機器の機器取付部43aを有し、磁石44は、回転板43が回転された際に、回転板43の表面に渦電流を発生させて、非接触で回転板43の回転を抑制するように回転板43と対向して配置される。【選択図】図3
