  • each first movement restricting portion 41g facing the meshing member 43 is not limited to the inclined surface, and may be, for example, a plane parallel to the end surface of the meshing member 43.
  • the surface of each second movement restricting portion 42e facing the meshing member 43 is not limited to an inclined surface, and may be, for example, a plane parallel to the end surface of the meshing member 43.
  • the inclined portion 42c is directly pushed by the pressing bolt 45, but another member may be interposed between the pressing bolt 45 and the inclined portion 42c.
  • either one of the first protrusion 43c and the second protrusion 43d may be omitted. In this case, it is possible to suppress the deviation of the first belt gripping tool 31 and the second belt gripping tool 32 with respect to the toothed belt 26 in one direction of the opening / closing operation direction of the first car door 12a and the second car door 12b.
  • both the first protrusion 43c and the second protrusion 43d may be omitted.
  • an intermediate protrusion may be provided in the middle of the base 43a in the longitudinal direction of the toothed belt 26. Also in this case, the intermediate protrusion portion protrudes from the base portion 43a in the direction opposite to the plurality of teeth 43b. Further, the intermediate protrusion portion is inserted into the intermediate groove provided in the first facing portion 41b or the second facing portion 42b.
  • cross section of the meshing member 43 does not necessarily have to be the same over the entire direction parallel to the width direction of the toothed belt 26.
  • the meshing member 43 may be omitted.
  • the elevator door device may be a central opening type door device as shown in FIG. 2 or a single opening type door device.
  • the number of doors is not particularly limited.
  • the door device of the elevator may be a landing door device as long as it is a door device using a toothed belt.
