To provide a hoist for an elevator capable of making unnecessary to adjust a caliper body position (readjustment) as much as possible.SOLUTION: A positioning mechanism to position a pin 54 of a caliper body 40 in an axial direction when releasing an electromagnetic brake 36 includes a return spring 76 to elastically energize the caliper body 40, a positioning bolt 70a and a sim 68a, where the positioning bolt is attached to a second bracket part 64 after a clearance dimension Gb between the positioning bolt and a stopper 74 is adjusted to a prescribed distance and is a contact member to move until it contacts to the stopper 74 with the caliper body 40 moving right on the page by the elastically energization at the releasing time, and a sim has a thickness corresponding to a displacing amount that the outer periphery of a brake disc part 24 displaces leftward on the page parallel to the axial direction when the basic axle load is applied to a sheave and is inserted between a first bracket part 62 and the second bracket part 64 in an extractable state.SELECTED DRAWING: Figure 3

    【課題】キャリパ本体の位置調整(再調整)を可能な限り不要にできるエレベータ用巻上機を提供する。【解決手段】電磁ブレーキ36の解除時にキャリパ本体40のピン54の軸心方向における位置決めをする位置決め機構を、キャリパ本体40を弾発付勢するリターンスプリング76と、ストッパ74との間の隙間寸法Gbが所定の距離に調整されて第2のブラケット部64に取り付けられ、解除時に前記弾発付勢によって紙面右向きに移動するキャリパ本体40と共に、ストッパ74に当接するまで移動する当接部材である位置決めボルト70aと、綱車に基本軸荷重が掛けられた際に、ブレーキディスク部24の外周部が前記軸心方向と平行な紙面左向きに変位する変位量に相当する厚みを有し、第1のブラケット部62と第2のブラケット部64の間に抜き取り可能な状態で挿入されたシム68aとを含むこと構成とした。【選択図】図3
