PURPOSE:To facilitate the attaching/detaching of a denture by using a fixing member made of a shape memory alloy to be thermal-restored in the range of a body heat. CONSTITUTION:A washer 1 is made of the shape memory alloy to be thermal- restored at the body heat of the degree of approximately 35 deg.C. The washer 1 has a washer 2 main body, where the denture fitting hole is pierced, and a pair of arm parts 3 and 3 to be extended from the washer 2 main body and to be face to each other in being curved. By the body heat, a pair of the arm parts 3 and 3 of the washer 1 are contracted, an anchor plate 4 is fasten-fixed, and the denture is attached. When an ice water, etc., is contained inside a mouth and the temperature of the washer 1 is lowered to approximately 20 deg.C or below, the arm parts 3 and 3 are expanded again, and the anchor plate 4 can be removed.
