A bone-ashes urn preserving case includes a case body, a soft cushion and two positioning members. The case body has a chamber in its interior, and the soft cushion is attached on a rear wall of the case body, and the positioning members are respectively adhered on the inner surfaces of two opposite sidewalls of the case body. Each positioning members are made of soft plastic, shaped as a palm with five fingers, having an inner embrace surface for softly embracing two sides of a bone-ashes urn when it is placed in the chamber of the case body, with the soft cushion resting against the rear side of the urn. So the urn never sways or inclines in the case body even in case of an earthquake, always safely kept therein without possibility of getting any damage.
