The present invention provides a hook device capable of automatically adjusting a relative position between a hook device and a center of gravity of a cargo and including a plurality of locking portions. The hook device includes a central shaft which extends in a first direction; and a first locking portion and a second locking portion which are disposed such that the central shaft is interposed therebetween, in a second direction orthogonal to the first direction. The first locking portion and the second locking portion are connected to the central shaft in a state where the first locking portion and the second locking portion are not rotatable independently around an axis extending in the first direction and are rotatable around an axis extending in a third direction different from the first direction and the second direction.
