A grounding apparatus of a switchboard door in a public house complex is provided to prevent an electric shock by flowing a leakage current to a ground through a ground band and a ground mother line. When a switchboard door is opened, a ground band(80) arranged at the switchboard door is elongated. One end of the ground band is fixed on a ground line connection plate, so that slide shoulder bolts(56,58) are moved in a straight line along guide holes(38a,38b). The slide shoulder bolts are fixed on a moving angle(60). When a slide shaft(70) welded on the moving angle is moved along a guide hole(39a), a return spring(72) is compressed between the moving angle and a shaft guide ankle(39), so that the ground band is suspended. The ground band is moved along free rotating rollers(40,42,44) and a tension roller(46). |
