Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a coupling member capable of securely coupling two members without providing a cavity on one member for attaching the other member.SOLUTION: A coupling member 20 sticks and couples an end surface 22b of a second member 22 to a side surface 21b of a first member 21. On the end surface 22b of the second member 22, a dovetail groove 22a which opens to the side surface 22c of the second member 22 and has inside wider than the end surface 22b is provided. On the side surface 21b of the first member 21, a cylinder hole 21a vertical to the side surface 21b is provided at a position opposite to the dovetail groove 22a. The coupling member 20 is composed of: a body member 10 integrally formed with a dovetail tenon portion 1 tightly fitted with the dovetail groove 22a and a hollow cylinder portion 2 tightly fitted with the cylinder hole 21a; and a fixing hardware 11 for fixing the body member 10 inserted in the hollow cylinder portion 2 to the side surface 21b of the first member 21.
【課題】一方の部材を取り付けるために他方の部材に空隙に設けることなく、かつ、2つの部材を強固に結合することができる結合部材を提供する。【解決手段】第1部材21の側面21bに第2部材22の端面22bを密着して連結する結合部材20であって、第2部材22の端面22bには、第2部材22の側面22cに開口し端面22bより内側が広い蟻溝22aが設けられており、第1部材21の側面21bには、蟻溝22aと対向する位置に側面21bに垂直な円筒穴21aが設けられており、結合部材20は、蟻溝22aに密に嵌合する蟻ほぞ部1と円筒穴21aに密に嵌合する中空円筒部2とが一体的に形成された本体部材10と、中空円筒部2に挿入され本体部材10を第1部材21の側面21bに固定する固定金物11とからなる。【選択図】図2 |
