A rotating device for a vehicle interior item is provided with latching means that is provided on a side of a base member having a rotation support part, and engagement means that is provided on a side of a rotating member supporting a vehicle interior item and being rotatably supported by the rotation support part, and can be switched between a state in which the engagement means engages with the latching means so as to suppress detachment of the rotating member from the base member and a state in which the engagement with the latching means is released when the rotating member attains the rotatable state, wherein the latching means (62) and the engagement means (63) are disposed further outside than the rotating member (23) in plan view at least when the rotating member (23) is in the non-rotating state. Accordingly, it is possible to suppress an increase in the height while suppressing detachment when the vehicle interior item is not rotating.
