PROBLEM TO BE SOLVED: To provide an anchor determining whether quality of subgrade is good or not, applicable only to a good subgrade, and exhibiting a reliable and simple anchor action.SOLUTION: The anchor provided with a pair of metal bars arranged parallel to one another has one end which is inclined in a broadening direction and the other end which is connecting means, and the metal bars are integrated together in the middle. Accordingly, when the anchor is driven down into the ground, the metal bars are gradually opened by resistance force received by the inclined planes and the anchor action can be exhibited. Thus, when the resistance force increases until the resistance force makes the metal bars bend and open, it becomes difficult to drive the anchor down further and it can be determined that the subgrade is firm. Moreover, a wire, a rope, or the like can be inserted through and easily connected to a ring-shaped ear hole by folding one metal bar at 180 degrees to make ring-shaped connection means of a folding bent part. 【課題】地盤の良し悪しを判別して良好な地盤のみに適用でき、またアンカー作用が確実で簡易なアンカーを実現する。【解決手段】１対の金属棒を互いに平行に備えたアンカーの一端は、末広がり方向に傾斜しており、他端は連結手段になっていて、中間で互いに一体化してあるので、地中に打ち込んだ際に、前記傾斜面の受ける抵抗力で前記金属棒を徐々に開かせることで、アンカー作用を発揮可能となる。従って、この抵抗力が前記金属棒を曲げて開かせるまで増大すると、それ以上は打ち込みが困難となるので、地盤がしっかりしていると判断できる。なお、１本の金属棒を約１８０度に折って、折り曲げ部をリング状の連結手段とすることで、リング状の耳穴にワイヤーやロープなどを挿通でき、連結が容易になる。【選択図】図３
