<P>PROBLEM TO BE SOLVED: To provide a door device for an elevator and a sill groove blocking device for an elevator, preventing a foreign matter from getting into a sill groove and achieving a long life. <P>SOLUTION: A movable blocking body 21 can be displaced between a blocking position for blocking an opening of a sill groove 7 at the upper part of the sill groove 7 provided in a sill 6 and an opening position positioned below the blocking position, for opening the opening of the sill groove 7. The movable blocking body 21 is displaced according to turning of an engaging link 32 with respect to the sill 6. The engaging link 32 has an engaging part 35 to be inserted into the sill groove 7. On a lower end part of a sliding door 11 for opening and closing an entrance 4, a cam 51 is provided. The cam 51 keeps the position of the movable blocking body 21 at the blocking position by pushing the engaging part 35 when the sliding door 11 is a door open position, and is detached from the engaging part 35 when the sliding door 11 is moved from the door open position to a door closing direction, to enable the movable blocking body 21 to displace to the opening position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
