Abstract:
1. A steerable traveling trunk which includes a retractable handle at an upper side of a traveling trunk body and a pair of wheels disposed at a lower side of the same, comprising: a driving part for converting a horizontal axis rotation of the handle into a vertical axis rotation at both ends of the handle and transferring the rotations as a user rotates the handle; a driving force transfer part which is connected to an upper side of the driving part and transfers the rotational force of the driving part to a lower side of the traveling trunk body and is formed in a retractable structure in the interior of a handle pole part; and an output part which is connected to a lower side of the driving force transfer part and transfers the rotational force transferred via the driving force transfer part depending on the rotation of the handle of the driving part to the wheels in an inclined direction, thus adjusting the steering angles of the wheels in leftward or rightward directions, wherein said driving force transfer part comprises a pair of first straight members of which upper sides are engaged to one of a pair of second bevel gear center shafts of the driving part, respectively, and a pair of second straight members into which each first straight member is inserted, and both the first and second straight members being formed of polygonal cross sections, and the vertical axis rotation of the first straight member is transferred to the vertical axis rotation of the second straight member.
