PROBLEM TO BE SOLVED: To provide a floating prevention structure for a ceiling crane capable of certainly preventing the floating of a traveling wheel from a travel rail at generation of an earthquake and accomplishing enhancement of earthquake resistance by a simple structure. SOLUTION: An auxiliary rail 10 is laid above the travel rail 2 through an auxiliary rail support base 11 so as to extend in parallel to the travel rail 2, the traveling wheel 5 provided on a crane girder 4 can be supported such that it is pressed by the auxiliary rail 10 from above at generation of the earthquake.
