       First Exemplary Embodiment 
       [0043]    Hereinafter, configuration of a camera module according to a first exemplary embodiment of the present disclosure will be described with reference to  FIGS. 1 to 4 . 
         [0044]      FIG. 1  is a perspective view illustrating a camera module according to a first exemplary embodiment of the present disclosure,  FIG. 2  is an exploded perspective view of a camera module according to a first exemplary embodiment of the present disclosure,  FIG. 3  is an exploded perspective view illustrating the way a rear body is formed with a packing accommodation groove according to a first exemplary embodiment of the present disclosure, and  FIG. 4  is a plan view illustrating the way a packing member is inserted into a packing accommodation groove according to a first exemplary embodiment of the present disclosure. 
         [0045]    Referring to  FIGS. 1 to 4 , a camera module according to a first exemplary embodiment of the present disclosure may include a front body ( 100 ), a rear body ( 200 ), a packing member ( 300 ), a lens part ( 400 ), an image sensor ( 500 ) and a PCB ( 600 , Printed Circuit Board). However, one or more elements may be omitted from the front body ( 100 ), the rear body ( 200 ), the packing member ( 300 ), the lens part ( 400 ), the image sensor ( 500 ) and the PCB ( 600 ), all of which forms the camera module. 
         [0046]    Referring to  FIGS. 1 and 2 , the front body ( 100 ) may include a front surface and a lateral surface extended from the front surface to a rear side. Meantime, the front body ( 100 ) may be a rear-side opened type. A front surface of the front body ( 100 ) may be formed with an opening coupled by a lens part. 
         [0047]    A front side of the rear body ( 200 ) may be coupled to a rear side of the front body ( 100 ) to thereby form an inner space. The front body ( 100 ) and the rear body ( 200 ) may be coupled by a screw ( 700 ). Furthermore, the front body ( 100 ) and the rear body ( 200 ) may be coupled by a hook or an adhesive agent. 
         [0048]    The packing member ( 300 ) may be interposed between the front body ( 100 ) and the rear body ( 200 ) to prevent moisture from entering from outside into an inner space formed by the front body ( 100 ) and the rear body ( 200 ). The packing member ( 300 ) may be formed to correspond to the front body ( 100 ) and the rear body ( 200 ). The packing member ( 300 ) may be formed to correspond to a shape of a rear surface of the front body ( 100 ) or a shape of a front surface of the rear body ( 200 ). However, the present disclosure is not limited thereto, and the packing member ( 300 ) may take any shape as long as the packing member ( 300 ) can perform the packing operation by being arranged at a coupled area between the front body ( 100 ) and the rear body ( 200 ). 
         [0049]    The lens part ( 400 ) may be stacked with at least one lens ( 410 ) to be assembled on a barrel ( 420 ). The barrel ( 420 ) assembled with the lens ( 410 ) may be mounted at an opening at a front side of the front body ( 100 ). A sealing member ( 430 ) may be interposed between the barrel ( 420 ) and the front body ( 100 ). The sealing member ( 430 ) may be an O-ring, for example. An inner space formed between the front body ( 100 ) and the rear body ( 200 ) is air-tightly sealed by the sealing member ( 430 ) and the packing member ( 300 ) to thereby prevent moisture or humidity from entering from outside. 
         [0050]    The image sensor ( 500 ) may concentrate the light incident by passing through the lens unit ( 400 ) to an electrical signal. The image sensor ( 500 ) may be accommodated at an inner space formed by the front body ( 100 ) and the rear body ( 200 ). 
         [0051]    The PCB ( 600 , Printed Circuit Board) may be mounted at a front surface with the image sensor ( 500 ). The PCB ( 600 ) may be accommodated at an inner space formed by the front body ( 100 ) and the rear body ( 200 ). The PCB ( 600 ) may include a connector (not shown) configured to electrically connect external devices including a power supply unit. 
         [0052]    Referring to  FIGS. 3 and 4 , the packing member ( 300 ) may include an inwardly protruded support part ( 320 ). The support part ( 320 ) of the packing member ( 300 ) may be formed with a through hole ( 350 ). Furthermore, the support part ( 320 ) may include a connection part ( 321 ) and a hitching part ( 322 ), for example. The hitching part ( 322 ) may be connected at a distal end to the connection part ( 321 ) and formed with a width broader than that of the connection part ( 321 ). The packing member ( 300 ) may include an avoidance part ( 370 ) so bent as not to interfere with the screw ( 700 ). The packing member ( 300 ) may be formed with a silicone or a ring-shaped rubber material, for example. 
         [0053]    The front body ( 100 ) and the rear body ( 200 ) may be injection molded with a metal or a synthetic resin. A front surface of the rear body ( 200 ) may be formed with a concaved packing member accommodation groove ( 310 ) to accommodate the packing member ( 300 ). Alternatively, the packing member accommodation groove ( 310 ) may be so formed as to be symmetrical at the front body ( 100 ) and the rear body ( 200 ). 
         [0054]    The concaved packing member accommodation groove ( 310 ) serves to prevent the packing member ( 300 ) from being detached. Furthermore, the concaved packing member accommodation groove ( 310 ) may include a support part accommodation groove ( 330 ) concavely formed to an inward side to accommodate the support part ( 320 ) of the packing member ( 300 ). In this case, it would be more effective to prevent the packing member ( 300 ) from being detached from the packing member accommodation groove ( 310 ). 
         [0055]    A front surface of the rear body ( 200 ), i.e., the support part accommodation groove ( 330 ), may be formed with a protruder ( 340 ). The protruder ( 340 ) may be inserted into the through hole ( 350 ) of the support part ( 320 ) to support the packing member ( 300 ). The packing member accommodation groove ( 310 ) may be thinner than the packing member ( 300 ). In this case, the sealing ability may be strengthened due to compression to the packing member ( 300 ) when the front body ( 100 ) and the rear body ( 200 ) are coupled. For example, when the packing member accommodation groove ( 310 ) is formed on a rear surface of the front body ( 100 ) and a front surface of the rear body ( 200 ), the depth of the packing member accommodation groove ( 310 ) formed on each of the rear surface of the front body ( 100 ) and the front surface of the rear body ( 200 ) may be smaller than a radius of the packing member ( 300 ). 
       Second Exemplary Embodiment 
       [0056]    Albeit not being illustrated in the drawings, the packing member accommodation groove ( 310 ) may be formed on a rear surface of the front body ( 100 ). That is, there is a difference from the first exemplary embodiment where the packing member accommodation groove ( 310 ) is formed at a front surface of the rear body ( 200 ). The explanation of the packing member accommodation groove ( 310 ) according to the second exemplary embodiment can be inferred from the packing member accommodation groove ( 310 ) according to the first exemplary embodiment. 
       Third Exemplary Embodiment 
       [0057]    Hereinafter, configuration of a camera module according to a third exemplary embodiment of the present disclosure will be described with reference to  FIGS. 5 and 6 . In explaining the third exemplary embodiment of the present disclosure, same reference numerals as in the first exemplary embodiment will be used to designate the same components, and redundant descriptions will be omitted. 
         [0058]      FIG. 5  is an exploded perspective view illustrating the way a partition wall is formed at a rear body according to a third exemplary embodiment of the present disclosure, and  FIG. 6  is a plan view illustrating the way a packing member is supported by a partition wall according to a third exemplary embodiment of the present disclosure. 
         [0059]    Referring to  FIGS. 1, 2, 5 and 6 , a camera module according to a third exemplary embodiment of the present disclosure may include a partition wall ( 360 ) formed at a front surface of the rear body ( 200 ) and more protruded than a thickness of the packing member ( 300 ) toward the front body ( 100 ) to prevent the packing member ( 300 ) from being detached. The partition wall ( 360 ) may be brought into contact with an inner side of the packing member ( 300 ). The partition wall ( 360 ) may prevent a mounting position of the packing member ( 300 ) from being twisted when the front body ( 100 ) and the rear body ( 200 ) are coupled. 
         [0060]    Meantime, the partition wall ( 360 ) may be discontinuous by forming a distancing part ( 361 ) to allow the support part ( 320 ) of the packing member ( 300 ) to crisscross. The distancing part ( 361 ) of the partition wall ( 360 ) may be so formed as to correspond to a part of the shape of the support part ( 320 ). For example, the distancing part ( 361 ) may accommodate the support part ( 320 ) by being so formed as to correspond to a width of the support part ( 320 ). When the support part ( 320 ) is formed as a hitching part ( 322 ) of the connection part ( 321 ), the distancing part ( 361 ) may be so formed as to correspond to a width of the connection part ( 321 ). At this time, the hitching part ( 322 ) may be so formed as to be wider than the connection part ( 321 ). In this case, the connection part ( 321 ) is arranged at the distancing part ( 361 ) and the hitching part ( 322 ) is hitched at an inner lateral surface of the partition wall ( 360 ), whereby the packing member ( 300 ) can be securely arranged between the front body ( 100 ) and the rear body ( 200 ). The support part ( 320 ) of the packing member ( 300 ) may be formed with a through hole ( 350 ) and the protrude ( 340 ) formed at the front surface of the rear body ( 200 ) may be inserted into the through hole ( 350 ) to restrict the movement of the support part ( 320 ). In this case, the packing member ( 300 ) may be securely arranged between the front body ( 100 ) and the rear body ( 200 ). 
       Fourth Exemplary Embodiment 
       [0061]    Albeit not being illustrated in the drawings, the partition wall ( 360 ) may be formed on a rear surface of the front body ( 100 ). That is, there is a difference from the third exemplary embodiment where the partition wall ( 360 ) is formed at a front surface of the rear body ( 200 ). The explanation of the partition wall ( 360 ) according to the fourth exemplary embodiment can be inferred from the partition wall ( 360 ) according to the third exemplary embodiment. 
         [0062]    Hereinafter, structure and shape of a packing member according to an exemplary embodiment of the present disclosure and according to a variation of exemplary embodiments of the present disclosure will be described.

         [0064]    Referring to  FIGS. 7 to 14 , the packing member ( 300 ) may be variably formed. Furthermore, a packing accommodation groove ( 310 ) or a partition wall ( 360 ) may be formed to correspond to various shapes of the packing member ( 300 ). 
         [0065]    Referring to  FIG. 7 , the packing member according to an exemplary embodiment of the present disclosure may include four (4) lateral sides. Each of the four (4) lateral sides at the packing member ( 300 ) may be protrusively formed toward an inner side of the support part ( 320 ). 
         [0066]    To be more specific, three (3) lateral sides out of the four (4) lateral sides of the packing member ( 300 ) may be arranged with support part ( 320 ) formed with the through hole ( 350 ).
