A vacuum retaining device capable of reuse includes a sucking disk member. The periphery of a disk surface portion of the sucking disk member is formed with a coupling edge portion wrapped and connected with a sealing rim. During use, the coupling edge portion inside the sealing rim forms a support, such that the shape and efficiency of the sealing rim can be kept for a long time. When a sealing surface of the sealing rim is poked to disengage from a surface to be adhered, the sealing surface is able to link the coupling edge portion of the sucking disk body. When the vacuum retaining device is not used, the outer edge of the sealing rim is poked for the air to enter the interior of the sucking disk body. The vacuum retaining device can be detached from the surface easily and conveniently.
