DOOR CONTACT MEMBER
To provide a door contact member that can suppress the collision noise generated when brought into contact with an object to be contacted, and has excellent durability.SOLUTION: A door contact member T includes a contact rubber 10 and a mounting metal fitting 20. The contact rubber 10 is made of synthetic resin foam with a semi-continuous bubble structure. The synthetic resin foam with the semi-continuous cell structure has physical properties of density 170 kg/m3 to 200 kg/m3 and tensile strength 0.34 MPa to 0.36 MPa, and the compressive properties showing the relation between compressibility and compressive stress at a room temperature for a test piece that is a cube of 10 mm on a side are the compressive stress at a compression rate of 60% is 0.01 MPa to 0.02 MPa, and the compressive stress at a compression rate of 80% is 0.2 MPa to 0.25 MPa.SELECTED DRAWING: Figure 2
【課題】 被当接体に当接した際に発生する衝突音を抑制可能であり、耐久性に優れた戸当たり部材を提供する。【解決手段】当接ゴム１０と、取付金物２０とを備え、当接ゴム１０は、半連続気泡構造を有する合成樹脂発泡体により形成されており、半連続気泡構造を有する合成樹脂発泡体は、密度１７０ｋｇ／ｍ３〜２００ｋｇ／ｍ３及び引張強度０．３４ＭＰａ〜０．３６ＭＰａの物性を有するとともに、１辺１０ｍｍの立方体である試験体に関する、常温時における圧縮率と圧縮応力の関係を示す圧縮特性は、圧縮率６０％時における圧縮応力が０．０１ＭＰａ〜０．０２ＭＰａ、かつ、圧縮率８０％時における圧縮応力が０．２ＭＰａ〜０．２５ＭＰａであることを特徴とする戸当たり部材Ｔとした。【選択図】 図２
