A following distance control device (1) that controls a vehicle to regulate a distance to a preceding vehicle to a target following distance, the following distance control device (1) including: detecting unit (30) that detect at least one of acceleration operation (12) or deceleration operation (13) by a driver; a target following distance changing unit that changes the target following distance on the basis of the acceleration operation (12) or the deceleration operation (13) by the driver that is detected by the detecting unit (30); and an inhibition unit that inhibits a changing amount of the target following distance by the target following distance changing unit when the given acceleration operation (12) or the given deceleration operation (13) is executed.
