         [0032]    Further, the insides of the upper and lower housings  22  and  24  are each provided with the hooks  42  so as to be locked the housings  22  and  24  to each other, such that it is possible to prevent the housing  22  and  24  from easily separating from each other. 
         [0033]    That is, the upper housing  22  has the sill or the hook  42  provided at an edge thereof and the lower housing  24  has a hook  42   b  provided at a predetermined portion of the inside thereof so that a hook  42   a  of the upper housing is fitted on the hook  42   b,  thereby locking the hooks  42   a  and  42   b  to each other as soon as the upper housing  22  is coupled with the lower housing  24 . 
         [0034]    Further, the locking member  40  may be configured to have a form in which the upper and lower housings  22  and  24  are each provided with fixed projections hole and fixed holes fitted on the fixed projections. 
         [0035]    In other words, the fixed projection and the fixed hole are each provided at corners at which the upper and lower housings  22  and  24  face each other to naturally couple the upper and lower housings  22  and  24  with each other while the upper housing adheres to the lower housing  24 . 
         [0036]    Meanwhile, a rib  30  melted by the high frequency fusion may be formed at a corner of any one of the upper and lower housings  22  and  24 . Preferably, a central portion of a corner of any one of the upper housing  22  and the lower housing  24  is provided with a protruded jaw  23  and the upper surfaces thereof may be provided with the rib  30 . 
         [0037]    Further, the housing in which the protruded sill  23  is not formed may be provided with a groove portion  25  so as to be fitted on the protruded sill  23 . 
         [0038]    For example, when the central portion of the upper housing  22  is provided with the protruded sill  23  along the corner thereof and the upper surface thereof is provided with the rib  30  along the protruded sill  23 , the lower housing  24  may be provided the groove portion  25  so as to be coupled with the protruded sill  23  of the upper housing. 
         [0039]    Therefore, when the upper housing  22  is coupled with the lower housing  24 , the rib  30  may be disposed between the upper housing  22  and the lower housing  24 . 
         [0040]    In addition, the upper housing  22  and the lower housing  24  are subjected to the high frequency fusion so that the housings  22  and  24  are firmly adhered to each other. 
         [0041]    The high frequency fusion is performed on the adhering portion of the upper housing  22  and the lower housing  24  to prevent foreign matters or moisture from being introduced through the adhering portion thereof. 
         [0042]    In this case, the high frequency fusion may be partially performed on the insides of the upper and lower housings  22  and  24 , based on the rib  30 . 
         [0043]    Further, the outsides of the housings  22  and  24  may be provided with a sealing rubbers  50  so as to prevent foreign matters and moisture from being introduced thereinto. 
         [0044]    When the insides of the housings  22  and  24  based on the rib  30  are partially subjected to the high frequency fusion, the upper and lower housings  22  and  24  are more easily separated from each other, and then the lens assembly  10  may be repaired and replaced at the time of the damage of the lens assembly  10 . 
         [0045]    Further, the lower housing  24  is integrated with the harness by the high frequency fusion. The harness  60  is a connector that supplies power of a vehicle battery to the lens assembly  10 . 
         [0046]    According to the camera  100  for a car according to the exemplary embodiment of the present invention, the upper and lower housings  22  and  24  is fixed by the locking member  40  when the lens assembly  100  is disposed within the upper and lower housings  22  and  24 . 
         [0047]    In this case, the locking member  40  may be configured in various forms, but when the insides of the upper and lower housings  22  and  24  are configured in the hooks  42   a  and  42   b,  the locking between the hooks  42   a  and  42   b  is performed during the process of adhering the upper housing  22  to the lower housing  24 . Here, only in any one of the upper and lower housings  22  and  24  is provided with the hook and the other thereof is provided with the sill. 
         [0048]    When the lens assembly  10  is provided in the upper and lower housings  22  and  24 , the upper and lower housings  22  and  24  are subjected to the high frequency fusion so as to maintain the firmly fixed state. The high frequency fusion may be performed over the adhering portion of the upper and lower housings  22  and  24  and may be partially performed according to the configuration of the rib  30 . 
         [0049]    When the rib  30  is provided at corners of the housings  22  and  24 , the rib  30  is melted while the high frequency fusion is performed to fill the gap of the adhering portion of the upper and lower housings  22  and  24 . Therefore, the upper and lower housings  22  and  24  may maintain the firm adhesion by the rib  30 . 
         [0050]    Further, the rib  30  may also be configured to partially perform the high frequency fusion in the state in which the rib is provided at the protruded sill  23  at the corner of the housing. In this case, based on the rib  30 , the insides of the housings  22  and  24  are subjected to the high frequency fusion and the outsides thereof may be provided with the sealing rubber  50 . 
         [0051]    As such, when the lens assembly  10  is mounted in the upper and lower housings  22  and  24 , the outer surface of the lower housing  24  is coupled with the harness  60  so as to be connected with the lens assembly  10 . The harness  60  is integrated with the lower housing  24  by the high frequency fusion in the state in which the harness  60  is adhered to the outer surface of the lower housing  24 . 
         [0052]    Therefore, the coupling of the upper and lower housings  22  and  24  and the coupling of the lower housing  24  and the harness  60  are performed by the high frequency fusion, thereby providing the firmly fixed camera  100  for a car without adding the separate components. 
         [0053]    According to the exemplary embodiments of the present invention, the camera for a car can increase the assemblage efficiency by simplified coupling between respective components using the ultrasonic fusion. 
         [0054]    Further, according to the exemplary embodiment of the present invention, it is possible to reduce the working process by performing the sealing process simultaneously with the tight waterproof process at the time of performing the ultrasonic fusion while maintaining a firm coupling relationship between respective components, thereby increasing productivity. 
         [0055]    Although the camera for a car according to the exemplary embodiments of the present invention is described above, the present invention is not limited thereto and therefore, applications and modifications thereof can be made by those skilled in the art.
