Disclosed are a toy block coupling structure and a toy block including the same. According to an embodiment of the present invention, the toy block has a structure in which blocks are provided in a block coupling toy so as to be coupled to each other, and comprises: a coupling protrusion; and a coupling hole into which the coupling protrusion is inserted to be coupled. An inner surface of the coupling hole comprises a plane portion which can come in line-contact with an outer circumferential surface of the coupling protrusion in the depth direction. Therefore, a coupling force between the toy blocks can be stably maintained. Also, the occurrence of defective toy blocks can be reduced, and the coupling force between toy blocks can be maintained to be uniform. Furthermore, the coupling of toy blocks can be facilitated. |
