  2. Description of the Related Art Conventionally, there is known an elevator sill groove shielding device for preventing foreign matter from entering a sill groove at the entrance of a car and a landing so that the door opening / closing operation is not hindered. In one device, one end of a closing band made of rubber belt or the like is fixed to the lower end of one door, and this closing band is wrapped around a pulley at the lower end of the other door, and is placed in a sill groove when the door is opened. A blocking band is laid to block the laying groove, and a weight is hung from the other end of the blocking band wrapped around the pulley to give tension to the blocking band. The obstruction band is stored on the door side by the weight of the weight (see, for example, Patent Document 1).

  In another elevator sill groove shielding device, a shielding band is provided that is loosely inserted into the sill groove and shields the sill groove, and this shielding band moves in the sill groove along with the closing movement of the door. It is pushed up from the sill groove by a shield band lifter that enters below. When the door moves in the opening direction, the shielding band is loosely inserted into the sill groove again from above the shielding band lifter to shield the sill groove (for example, see Patent Document 2).
