For example, The case groove 320 may be formed in the left side surface portion and the right side surface portion of the case 30 in correspondence with the position of the second tab 420, Or the second tab 420 is provided on all four sides of the bezel 400, the case groove 320 may be formed in the case 300 (corresponding to the position where the second tab 420 is provided) As shown in FIG.

The second tab 420 and the case groove 320 are provided on at least one pair of opposite side portions so that the engagement of the second tab 420 and the case groove 320 can be made firm.

The second tab 420 is made of an elastic material and can be coupled with the case groove 320 in a one-touch manner.

The second tab 420 and the case groove 320 are separated from each other by a method in which the tab is pressed when a certain force is applied to the second tab 420 and then returned to the original state by elasticity when the applied force disappears, Can be combined in a one-touch manner.

7, when the bezel 400 is coupled to the front portion of the case 300, the second tab 420 is pushed by the case groove 320, When the case groove 320 is coupled with the second tab 420, the force for pushing the second tab 420 disappears, so that the second tab 420 returns to its original state, The second tab 420 is fixed to the case groove 320 while being positioned inside the case groove 320 so that the second tab 420 and the case groove 320 can be engaged with each other.

That is, the bezel 400 and the case 30 can be coupled in a one-touch manner through the one-touch connection of the second tab 420 and the case groove 320.
