A luggage hook for detachably attaching to an attachment location, comprising: a base ; a belt attached to the base for wrapping around the attachment location; a primary hook member comprising a cylindrical primary neck section attached at a proximal end thereof to the base , and an upward-opening primary hook body attached to a lower end of the primary neck section , extending downward from the lower end of the primary neck section and then bending upward; and a secondary hook member comprising a secondary neck section attached to the primary neck section , and an upward-opening secondary hook body attached to the secondary neck section , extending downward from the secondary neck section and then bending upward; the primary hook body and the secondary hook body being configured so that one or both thereof rotate relative to the base around a central axis of rotation (R), being provided so that positions thereof in a vertical direction partially overlap, but so as not to interfere with each other even when one or both thereof are rotated relative to the base , and being configured so that, when rotational-direction positions thereof are aligned, the secondary hook body narrows and blocks an open part of the primary hook body ; characterized in that the primary hook body has a letter-C like shape with an upward-opening and protrudes in different directions with the central axis of rotation (R) in between; and the secondary hook body has a letter-J like shape with an upward-opening and protrudes to only one side of the central axis of rotation (R); and wherein the center of the primary hook body is displaced from the central axis of rotation (R) toward the open part of the primary hook body; and the center of the secondary hook body is displaced from the central axis of rotation (R) toward the open part of the secondary hook body. a base ; a belt attached to the base for wrapping around the attachment location; a primary hook member comprising a cylindrical primary neck section attached at a proximal end thereof to the base , and an upward-opening primary hook body attached to a lower end of the primary neck section , extending downward from the lower end of the primary neck section and then bending upward; and a secondary hook member comprising a secondary neck section attached to the primary neck section , and an upward-opening secondary hook body attached to the secondary neck section , extending downward from the secondary neck section and then bending upward; the primary hook body and the secondary hook body being configured so that one or both thereof rotate relative to the base around a central axis of rotation (R), being provided so that positions thereof in a vertical direction partially overlap, but so as not to interfere with each other even when one or both thereof are rotated relative to the base , and being configured so that, when rotational-direction positions thereof are aligned, the secondary hook body narrows and blocks an open part of the primary hook body ; characterized in that the primary hook body has a letter-C like shape with an upward-opening and protrudes in different directions with the central axis of rotation (R) in between; and the secondary hook body has a letter-J like shape with an upward-opening and protrudes to only one side of the central axis of rotation (R); and wherein the center of the primary hook body is displaced from the central axis of rotation (R) toward the open part of the primary hook body; and the center of the secondary hook body is displaced from the central axis of rotation (R) toward the open part of the secondary hook body. <EOS>
