Therefore, even when the operation speed of {TAIL ~ the operating portion} is {HEAD ~ any operation speed}, such as 0, it is possible to effectively prevent the oscillations and vibrations from being applied to the operating portion by the operator due to the oscillations and vibrations of, for example, the construction machinery
