TURNING CONTROL DEVICE AND TURNING DEVICE

To reduce error between virtual rack end positions and actual rack end positions. A terminal position learning unit (46) includes a first storage unit (72) configured to store a steered position positioned farthest from a neutral position of a turning mechanism within a range of a steered position detected by a position detection unit (14) when rotational force applied to the turning mechanism is less than or equal to a first predetermined value, a second storage unit (76) configured to store a steered position positioned farthest from the neutral position within a range of a position to which a steered position detected by the position detection unit (14) is shifted in a direction toward the neutral position of the turning mechanism by a second predetermined value, and a third storage unit (78) configured to store, as a terminal position stored by the terminal position learning unit (46), one of the steered positions stored in the first storage unit (72) and the second storage unit (76) positioned farther from the neutral position than the other.
