The present invention relates to a power transmission apparatus for transmitting power between components, and a built-up type toy including the same. The power transmission apparatus comprises: a housing having an operating space formed therein; a connection hole that is open in at least one direction of the housing; a gear assembly that operates in the operating space of the housing and has a connecting link on one end thereof which is exposed to the outside through the connection hole; and a coupling tube for selectively interconnecting two connection holes of the power transmission apparatus and a counterpart power transmission apparatus connected thereto, wherein the connecting link of the power transmission apparatus and a counterpart connecting link are connected and interworked with each other in the interior of the coupling tube. As described above, according to the present invention, the power transmission apparatuses for transmitting power are configured to have one independent housing and have functions such as turning or decelerating, and various functions and applications can be embodied through simple coupling therebetween, so that young users can easily implement a power transmission structure as well, thereby enhancing usability. |
