To provide a winch drum and a crane comprising it, in which it is suppressed that a rope is wound randomly due to fine adjustment of the distance between flanges even if there are variations in the diameter of the rope and the distance between the flanges.SOLUTION: In a winch drum 1, a regulating member 10 has a regulating surface S1 which is located on the outer side W2 in the width direction with respect to a regulated surface S2 constituted by a part of an outer surface 322 of a first flange 3A and contacts to the regulated surface S2 so as to regulate displacement of the first flange 3A to the outer side W2 in the width direction. The regulating member 10 is so configured that the regulating surface S1 is displaced to the inner side W1 in the width direction due to rotation of a bolt 6 in a tightening direction and the regulating surface S1 is displaced to the outer side W2 in the width direction due to rotation of the bolt 6 in the direction opposite to the tightening direction.SELECTED DRAWING: Figure 4

    【課題】ロープの径のばらつきやフランジ間の距離のばらつきがあっても、フランジ間の距離を細かく調節することによってロープの乱巻きが生じるのを抑制することができるウインチドラム及びこれを備えたクレーンを提供する。【解決手段】ウインチドラム1では、規制部材10は、第1フランジ3Aの外側面322の一部によって構成される被規制面S2に対して幅方向外側W2に位置するとともに被規制面S2に当たることにより第1フランジ3Aの幅方向外側W2への変位を規制する規制面S1を有し、規制部材10は、ボルト6を締め付け方向に回転させることにより規制面S1が幅方向内側W1に変位する一方で、ボルト6を締め付け方向の反対方向に回転させることにより規制面S1が幅方向外側W2に変位するように構成されている。【選択図】図4
