To provide a rail installation device of an elevator by that a rail positioning unit can easily and surely return to the same position as before the rail positioning unit is separated from a rail fixing unit.SOLUTION: A rail installation device of an elevator includes a rail positioning unit 4 capable of holding a rail 9, and a rail fixing unit 3 capable of placing the rail positioning unit 4. The rail positioning unit 4 includes a first extension/contraction part 42 extensible/contractible in a direction directed to the rail 9, and a second extension/contraction part 46 extensible/contractible in a direction directed to an inner wall surface 5 of a hoistway 2. The rail positioning unit 4 executes a first control mode in which the rail positioning unit is supported by the inner wall surface 5 by the extension of the second extension/contraction part 46 and separated from the rail fixing unit 3 such that a position of the rail 9 is determined by the extension/contraction of the first extension/contraction part 42 and the second extension/contraction part 46 while holding the rail 9, and a second control mode in which after the rail 9 is fixed to the inner wall surface 5, the second extension/contraction part 46 is contracted and the rail positioning unit is not supported by the inner wall surface 5 and is placed on the rail fixing unit 3 again in response to the extension and contraction of the first extension/contraction part 42.SELECTED DRAWING: Figure 2

    【課題】レール位置出しユニットが、レール固定ユニットから分離したときと同じ位置に容易かつ確実に戻ることができる、エレベータのレール据付装置を提供する。【解決手段】レール9を把持可能なレール位置出しユニット4と、レール位置出しユニット4を載置可能なレール固定ユニット3を備える。レール位置出しユニット4は、レール9に向かう方向に伸縮可能な第1伸縮部42と、昇降路2の内壁面5に向かう方向に伸縮可能な第2伸縮部46を備える。レール位置出しユニット4は、第2伸縮部46の伸長で内壁面5に支持され、レール固定ユニット3から分離して、レール9を把持して第1伸縮部42と第2伸縮部46の伸縮によりレール9の位置を決める第1の制御モードと、レール9が内壁面5に固定された後、第2伸縮部46が収縮して内壁面5で支持されずに、第1伸縮部42の伸縮とともにレール固定ユニット3に再び載置される第2の制御モードを実行する。【選択図】図2
