To provide a pulley in which a wire can be easily wound.SOLUTION: A pulley 1 of the present invention includes a main winding portion 2 in which an annular main winding groove 23 on which the wire W can be wound is formed between a first flange 21 and a second flange 22, and an auxiliary winding portion 3 in which an auxiliary winding groove 32 on which the wire W can be wound is formed between the second flange 22 and a third flange 31. The auxiliary winding groove 32 has a closest contact portion 321 that is closest to the main winding groove 23 in the radial direction of the main winding groove 23. The auxiliary winding groove 32 has a curved portion 322 that curves toward the main winding groove 23 at a portion adjacent to the closest contact portion 321 so as to merge with the main winding groove 23 at the closest contact portion 321. The third flange 31 has an auxiliary guide portion 311 extending in the radial direction of the auxiliary winding groove 32 so that a groove depth D2 of the curved portion 322 is larger than a groove depth D1 of the closest contact portion 321.SELECTED DRAWING: Figure 3A

    【課題】ワイヤを容易に巻き掛けることが可能なプーリを提供する。【解決手段】本発明のプーリ1は、第1のフランジ21と第2のフランジ22との間にワイヤWが巻き掛け可能な環状の主巻き掛け溝23が形成された主巻き掛け部2と、第2のフランジ22と第3のフランジ31との間にワイヤWが巻き掛け可能な補助巻き掛け溝32が形成された補助巻き掛け部3とを備え、補助巻き掛け溝32は、主巻き掛け溝23の径方向で主巻き掛け溝23に最も近接する最近接部321を有し、補助巻き掛け溝32は、最近接部321において主巻き掛け溝23と合流するように、最近接部321に隣接する部分において主巻き掛け溝23に向かって湾曲する湾曲部322を有し、第3のフランジ31は、湾曲部322の溝深さD2が最近接部321の溝深さD1よりも大きくなるように、補助巻き掛け溝32の径方向に延びる補助案内部311を有している。【選択図】図3A
