Abstract
To provide a characteristic measuring device capable of smoothly switch switching between a floating-mass state and a fixed state, while a predetermined pre-load is maintained. In a characteristic measuring device, a support part includes an air spring and a double fastening mechanism each arranged between a middle surface plate and a reaction-force section, the double fastening mechanism includes a first actuator fixed to the reaction-force section and a second actuator fixed to the middle surface plate, and the reaction-force section is not supported in the floating-mass state and is supported in the fixed state by the first actuator and the second actuator. In this way, a problem of the prior art (pre-load variation) is eliminated, and switching between the floating-mass state and the fixed state can be smoothly achieved.
