PROBLEM TO BE SOLVED: To provide a rotary hook in which rotation of a lower hook under an unloaded condition can be suppressed, and an electric chain block.SOLUTION: A rotary hook 100 comprises: a lower hook 200 on which a load can be hooked; a lower hook shaft 170 which is so provided as to be continuous with the lower hook 200; a rotation suppression mechanism 140 for suppressing rotation of the lower hook 200; and force application means 190 for applying a force onto the rotation suppression mechanism 140. The rotation suppression mechanism 140 suppresses the lower hook 200 by a self-weight by force application of the force application means 190 in the state that a load is hooked on the lower hook 200, and releases suppression of rotation of the lower hook 200 in the state that the load is not hooked on the lower hook 200.SELECTED DRAWING: Figure 2

    【課題】無負荷状態での下フックの回転を抑制することが可能な回転フックおよび電気チェーンブロックを提供する。【解決手段】回転フック100は、荷を掛け止めることが可能な下フック200と、下フック200と連続する状態で設けられている下フック軸170と、下フック200の回転を抑制する回転抑制機構140と、回転抑制機構140に対して力を加える加力手段190と、を備え、回転抑制機構140は、下フック200に荷が掛け止められてない状態では、加力手段190の加力によって下フック200の自重による回転を抑制する一方、下フック200に荷が掛け止めされた状態では、下フック200の回転の抑制が解除される。【選択図】図2
