The counterweight 9 is supported on the hoistway 1 by a pair of weight- side guide rails 3A and 3B erected in the hoistway 1 so as to be able to ascend and descend. The pair of weight- side guide rails 3A and 3B are arranged on one end side of the hoistway 1 in the width direction X. As shown in FIG.
第１おもり側ガイドレール３Ａは、マシンビーム４Ａよりも前後方向Ｙの前側に配置される。そして、第１おもり側ガイドレール３Ａは、かご側ガイドレール２を支持するレールブラケット８に支持される。第２おもり側ガイドレール３Ｂは、マシンビーム４Ａよりも前後方向Ｙの後側に配置される。そして、第２おもり側ガイドレール３Ｂは、昇降路１における背面側壁面１Ｂに固定されたレールブラケット８に支持される。そのため、第１おもり側ガイドレール３Ａと第２おもり側ガイドレール３Ｂは、巻上機４及びマシンビーム４Ａを前後方向に沿って挟むようにして配置される。そのため、釣合おもり９は、上下方向から見た投影面において巻上機４の下方に配置される。また、第２おもり側ガイドレール３Ｂは、乗りかご５よりも前後方向Ｙの後側に配置されている。
The first weight-side guide rail 3A is arranged in front of the machine beam 4A in the front-rear direction Y. The first weight-side guide rail 3A is supported by a rail bracket 8 that supports the car-side guide rail 2. As shown in FIG.
