PURPOSE: An elastic coupling device of a snap coupling type is provided to assemble parts without any screw, any separate space, and avoid exposure of the coupling device. CONSTITUTION: An elastic coupling device(30) comprises a lower locking part(32), an upper locking part(34), and a grip(36). The lower locking part(32) is protruded along the bottom boundary of the elastic coupling device(30) in a uniform interval, and inserted into a lower locking groove(42) of a rear cabinet(40). The upper locking part(34) is protruded lengthwise, and inserted into an upper locking groove(44) of the rear cabinet(40). The grip(36) is protruded lengthwise along the opposite boundary to the lower locking part(32). A front cabinet(50) includes a protruded bracket(52). The free end of the bracket(52) is inserted into a coupling groove(38) of the elastic coupling device(30) in contact with an upper protrusion(46) of the rear cabinet(40).
