Zusammenfassung:	The present invention relates to a device for measuring the vibration of a nuclear reactor. An acceleration sensor or a sensor protection member for protecting the same is detachably coupled to an inner structure which supports a control rod assembly or a nuclear fuel assembly by using a fixing nut and a coupling bolt. Therefore, the acceleration sensor can be easily separated by separating the fixing nut from the sensor protection member after evaluating vibration, thereby preventing the deformation of the inner structure due to the detachment of the sensor protection member.
