PURPOSE: A vacuum displaying device of a cinerary urn is provided to confirm a vacuum state of the inside of a cinerary urn vacuumized by the operation of an air suction device and a vacuum pressure change of the inside of the cinerary urn with unaided eyes, thereby improving reliability with respect to a product. CONSTITUTION: A vacuum displaying device(100) of a cinerary urn comprises a movement guide member(110), a display window(120), a gauge(130), and a display member(140). The movement guide member is mounted on a bottom surface of a vacuum cover(20) closing the inside of a cinerary urn, thereby guiding the movement of the gauge and the display member. The display window is mounted in the vacuum cover so that a vacuum state of the inside of the cinerary urn can be confirmed. The gauge is sixed in the inner side of the movement guide member, thereby moving while shrinking or expanding according to the vacuum pressure of the inside of the cinerary urn. The display member comprises a rib(141) being fixed to a shaft protruded on the gauge so that the vacuum state of the inside of the cinerary urn is displayed on the display window. The display member is fixed orthogonal to the rib and comprises a displaying plate(142) divided into two parts with two colors.본 발명은, 유골이 보관된 납골함 내부의 공기를 공기흡입장치의 작동으로 납골함 외부로 배출하여 진공되는 납골함 내부의 진공상태 및 진공된 납골함 내부의 진공압 변화를 육안으로 용이하게 확인함과 아울러 납골함 내부의 진공압에 따라 용이하게 대처할 수 있도록 하는 납골함의 진공 표시장치에 관한 것이다.
