The present invention relates to a caster vibration testing device including: a caster mounting unit wherein a caster to be tested is mounted; a vibration generating unit composed of a roller member coming into contact with wheels of the mounted caster and having protrusions for the vibration of the caster protruding from an outer surface and a driving motor rotating the roller member; and a load applying unit measuring a change in a load due to the vibration while applying a load to the mounted caster. According to the present invention, reliable test data with respect to the vibration performance of the case can be provided. In addition, the vibration performance can be visually checked during a testing process. Furthermore, an effect of testing the vibration performance of the casters with various sizes in various testing conditions is obtained.;COPYRIGHT KIPO 2016
