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, 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 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; and wherein the center of the primary hook body is displaced from the central axis of rotation 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 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, 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 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; and wherein the center of the primary hook body is displaced from the central axis of rotation 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 toward the open part of the secondary hook body.
