<p>The present invention relates to a fastening device capable of tightly coupling two components and, more specifically, to a fastening device comprising: an elastic arm (12) for coupling a first body (10) and a second body (20) to each other; and an engaging part (22) formed in the second body (20) to be coupled to the elastic arm (12). A coupling protrusion (14) is formed on the tip end of the elastic arm (12) to protrude toward the second body (20). An end protrusion (14′) having a complete coupling surface (15) formed thereon and a separate type groove part (18) for insertion of a tool are formed on the coupling protrusion (14). The complete coupling surface (15) is formed on one side of the end protrusion (14′) to be engaged with the second body (20). An engaging protrusion (23) is formed in the engaging part (22) to be engaged with the end protrusion (14′) of the coupling protrusion (14). A complete coupling groove (26) is formed on one side of the engaging protrusion (23) to position the end protrusion (14′) of the coupling protrusion (14) in a complete coupling state, and a temporary coupling groove (28) is formed on the other side of the engaging protrusion (23) to position the end protrusion (14′) of the coupling protrusion (14) in a temporary coupling state. According to the fastening device of the present invention as above, since two components can be coupled to each other in a complete coupling state and a temporary coupling state, the components can be easily separated from each other while being tightly coupled to each other.</p> |
