Abstract
A reference vibratorof the present invention includes: a vibrator bodyconfigured to mount to a mountin an unbalance measurement deviceto which a rotary product is mounted at the time of unbalance measurement, in a same mounting state as the rotary product; a vibration generatorfixed to the vibrator bodyand that applies vibrations to the vibrator body; and a control unitthat controls the vibration generator. Because vibration is caused by the vibration generatorfixed to the vibrator body, repeatability of vibration force is high. This makes it possible to apply vibrations for repeatability check to the unbalance measurement devicewith an accurate vibration force. Thus, variations in vibration force can be eliminated, and the repeatability of the unbalance measurement devicecan be properly checked.
