The present invention relates to a hook of a ceiling crane seismic apparatus, which press a roller (7) with a spring by relying on a flange (9) fixed to a building so as to maintain a required gap of a hook (2) in an emergency. According to the invention, in a slewing structure in which the circumference of the flange (9) of the structure installed in a cylindrical building has a tolerance of bending, preliminary spacing required for the flange (9) to which the hook (2) of one body is opposed is maintained by pushing the roller (7) against the flange (9) with a pressing force of the spring (1) compensating for the tolerance.
