To provide a hanger storage tool whose occupied floor area can be reduced when it stores hangers.

The hanger storage tool 5 is provided with a support 2 which extends from a support base 1 in the vertical direction and hanger holders 3 which are arranged around the central axis of the support 2 in a rotatable manner. Each of the hanger holders 3 is provided with arms 31 which are spaced apart at 120° with respect to one another. Each of the arms 31 comprises an interference preventing arm part 31a which is separated from the central axis of the support 2 by a predetermined length and a hanger hooking arm part 31b which extends from the interference preventing arm part 31a at an angle of 60° through an inflected part 31c. In this way, wasted space between hangers which are hooked on the hanger hooking arm parts 31b is prevented and the occupied floor area can be reduced when the hangers are stored.
