         [0137]      FIGS. 17C and 17D  illustrate the adaptor part  203  with the connector  300  mounted thereto. Further,  FIG. 9C  is a perspective view of the wiper blade in which the adaptor part connectable with the wiper arm  20  in a U-hook type is mounted to the seating part  206  and the connector is coupled to the adaptor part. 
         [0138]    Since a shape of the connector  300  coupled with the wiper arm in the U-hook type is the same as a shape of the conventional connector  300 , its detailed description will be omitted. A shape of the upper portion of the adaptor part  200  with the connector  300  mounted thereto is the same as a conventional shape, but a bottom surface includes the embossing structure and the adaptor part latch as described above. 
         [0139]    As described above, since the adaptor part  203  can be attached and removed, the adaptor part  203  can be coupled with various wiper arms  20  in one wiper blade  10 . 
         [0140]    Next, an embodiment of the connector will be described. 
         [0141]    Prior to describing the embodiment of the connector, a shape of the wiper arm which can be connected to the connector according to the present invention will be described. 
         [0142]      FIGS. 9A ,  9 B, and  9 C are views illustrating connection states of the wiper arm  20  applied to an embodiment of the present invention. 
         [0143]      FIGS. 9A ,  9 B, and  9 C are partial perspective views illustrating states where the wiper arm in a Bosch type, the wiper atm in a top-lock type, and the wiper arm in the U-hook type are connected to the connector according to the present invention, respectively. 
         [0144]    As illustrated in  FIGS. 9A ,  9 B, and  9 C, the wiper blade  10  for the vehicle is attachably/removably mounted to the wiper arm  20  connected to a driving source of a vehicle body and configured to transfer rotation power, the wiper arm  20  having a predetermined length. Since the connector  300  is mounted to the wiper blade illustrated in  FIGS. 2A and 2B , the wiper illustrated in FIGS.  9 A.,  9 B, and  9 C can be coupled to the connector  300 . The adaptor part  200  is installed within the connection holder part  412 , so that the adaptor part  200  can be assembled with various types of driving arms together with the connector  300  described below. 
         [0145]      FIGS. 14A ,  14 B,  14 C, and  14 D are views illustrating the connector mounted to the adaptor part  200 .

The adaptor part  200  is formed of a resin material, and thus the fitting recess  222  elastically receives fitted part  351  of the connector  300 , which prevents the connector  300  from being, separated from the adaptor part  200 . 
         [0152]    Referring to  FIGS. 14A to 14D , the first coupling part  331  includes a slot groove formed in the first coupling part  331  for guiding the wiper arm from an upper portion to a lower portion of the connector  300  in order to be connected with the wiper arm in the top-lock type having the catching protrusion and a sliding part formed in the lower portion of the connector  300  supported by the backwardly slid catching, protrusion of the wiper arm  20  guided along the slot groove. 
         [0153]    When the catching protrusion of the wiper arm  20  is formed in a center of the wiper arm  20 , the second coupling part  341  supports the catching protrusion. The head part  311  is formed in a front of the first coupling part  331  of the connector  300 , and includes the head part cover  311   b  and the head part body  311   a . The head part cover  311   b  covers an upper portion of the head part body  311   a  The head part cover  311   b  covers a top of a part of the front end of the wiper arm to prevent the wiper arm from moving forwardly, backwardly, and upwardly. A first lower end part  352  formed in a lower portion of the head part  311  engages with the first receiving groove  223  of the adaptor part  200 , and a second lower end part  353  formed in a lower portion of a back end portion of the connector  300  engages with the second receiving groove  224  of the adaptor part  200 . The head part cover  311   b  covers a top of the head part  311 . 
         [0154]    Referring to  FIGS. 10A ,  10 B, and  10 C, and  FIGS. 14A to 14D , the coupling between the connector  300  and the adaptor part  200  will be described. 
         [0155]      FIG. 17A  illustrates a type in which the connector  300  is mounted to the adaptor part  200 . 
         [0156]    The connector  300  is coupled with the adaptor part  200  from a top to a bottom of the adaptor part  200 . The connector  300  includes the fitted part  351  received in the fitting recess  222  of the adaptor center pan  212 . The fitting recess  222  of the adaptor center part  212  elastically pressurizes the fitted part  351  in a horizontal direction to prevent the connector  300  from being separated from the adaptor part. 
         [0157]    As illustrated in  FIG. 15B , the connector  300  is mounted to the adaptor part  200 , the wiper arm in the top-lock type which can be connected to the connector  300  includes the fitted part for the coupling with the connector  300 , the fitted part being vertically induced along the first coupling part  331  of the connector  300  from a top to a bottom of the first coupling part  331 , and the wiper arm is slid toward a back of the connector  300  along a lower end of the first coupling part  331  and rear supported. Further, since the head part  311  of the connector  300  is horizontally fixed, a forward movement of the wiper arm is controlled by the head part cover  310   b.    
         [0158]    As illustrated in  FIG. 15A , the connector  300  includes the second coupling part  341  in order to be coupled with the wiper arm  20  having the fitted part spaced apart from the front end of the wiper arm  20 , such as the wiper arm in the Bosch type, by a predetermined distance.

         [0160]    In a case where the wiper arm  20  is coupled to the connector  300 , when the wiper arm  20  is coupled with and supported by the first coupling part  331  or the second coupling part  341  formed in sides of the connector  300 , the head part cover  311   b  of the connector  300  is slid toward the back of the connector  300  along the guide part  361 , and the elastic catching piece  362  formed in sides of the head part body  311   a  of the connector  300  is outwardly inserted in and is coupled with the catching recess  363  formed in sides of the head part cover  311   b . Accordingly, forward, backward, and upward movements of the wiper arm  20  are restricted. 
         [0161]    A process of separating the wiper arm  20  from the wiper blade assembly will be described. 
         [0162]    When the elastic catching pieces  362  outwardly inserted in the catching recesses  363  of the head part cover  311   b  are pressed from both sides and thus released from the catching recess  363 , the connector head part cover  311   b  is forwardly slid along the guide part  361 , and can rotate by 90 degrees in a front bottom direction of the connector. When the head part cover  311   b  of the connector  300  rotates about the coupling protrusion  365  formed in the head part cover  311   b , the wiper arm  20  can be separated from the first coupling part  331  or the second coupling part  341   
         [0163]      FIGS. 16A to 16D  illustrate the connector  300  mounted to the adaptor part  201 . Referring to  FIGS. 16A to 16D , a lower portion of the connector  300  is opened to be coupled with the adaptor pan  201 . Referring to  FIGS. 16A to 16D , the connector  300  may include a connector body  320  and the connector head part  310 . 
         [0164]    The connector body  320  may include a fitted part  350  for a coupling with the adaptor pan  201 , a first coupling part  330  for a coupling with the wiper arm in the top-lock, type, and a second coupling part  340  for a coupling with the wiper arm in the Bosch type. The fitted part  350  is received in the fitting recess  220  of the adaptor part  201  illustrated in  FIG. 11A . The connector head part  310  may include a head part body  310   a  and a head part cover  310   b . The head part cover  310   b  can move along a slope of the front end  230  of the concave part  240 . 
         [0165]    Referring to  FIGS. 11A and 16D , the lower portion of the connector  300  is opened to receive the adaptor part  200 . An interior of the lower portion of the connector  300  includes the fitted part  350  received in the fitting recess  220  of the adaptor part  200  to mount the connector  300  to the adaptor part  200 .

Further, the connector  300  includes the second coupling part  340  in order to be coupled with the wiper arm  20  having the fitted part spaced apart from the front end of the wiper arm  20 , such as the wiper aim in the Bosch type, by a predetermined distance. The coupling protrusion of the wiper arm is inserted in the second coupling part  340  and thus rear supported. 
         [0167]    The head part  310  is in front of the first coupling part  330  on the connector  300 , and the head part  310  includes the head part cover  310   b  and the head part body  310   a . The front end of the head part body  310   a  is formed to become higher so that the head part  310  engages with the one end  230  of the concave part  240 , and the head part cover  310   b  is formed to cover an upper portion of the head part body  310   a . The head part cover  310   b  covers a top of a part of the front end of the wiper arm  20  to prevent the wiper arm  20  from moving forwardly, backwardly, and upwardly. 
         [0168]    The coupling between the connector  300  and the adaptor part  201  will be described with reference to  FIGS. 11A and 11B ,  FIGS. 16A to 16D , and  FIG. 17B . 
         [0169]      FIG. 17B  illustrates that the connector  300  is mounted to the adaptor part  201 . 
         [0170]    The connector  300  is coupled to the adaptor part  201  from a top to a bottom of the adaptor part  201 . The fitted part  350  of the connector  300  is guided by the guide recess  219  and inserted in the fitting recess  220 . The guide recess  219  may form a slope of which a horizontal direction width is increased toward the fitting recess  220  from an upper portion of the adaptor part  201 . Accordingly, a coupling with the fitting recess of the connector  300  is easily achieved, and the connector  300  is not easily separated. 
         [0171]    The connector  300  includes the fitted part  350  received in the fitting recess  220  of the adaptor part  201 . The fitted part  350  inserted in the fitting recess  220  of the adaptor part  201  elastically pressurizes the adaptor part  201  in a horizontal direction to prevent the connector  300  from being separated from the adaptor part  201 . 
         [0172]    Hereinafter, a method of coupling the wiper arm to the connector  300  in a state where the connector  300  is mounted to the adaptor part  201  will be described. 
         [0173]    The connector  300  is mounted to the adaptor part  201 , and the wiper arm  20  is coupled to the connector  300 . The wiper arm in the top-lock type has the catching protrusion for the coupling with the connector  300 , is vertically induced along the first coupling part  330  of the connector  300  from a top to a bottom of the first coupling part  330 , and is slid toward the back of the connector  300  in the lower end of the connector  300  and rear supported. Further, since the head part  310  of the connector  300  is horizontally fixed, the forward movement of the wiper arm is controlled by the head part cover  310   b.    
         [0174]    The wiper arm  20  having the latch spaced apart from the front end of the wiper arm  20  such as the wiper arm in Bosch type by a predetermined distance has the coupling protrusion for the coupling with the connector  300 , and the connector  300  includes the Bosch coupling part  340  for the coupling with the wiper arm. The coupling protrusion of the wiper arm is inserted in the second coupling part  340  of the connector  300  and rear supported. The head part  310  covers the top of the front end of the wiper arm  20 . When the head part  310  is horizontally fixed, the rotation and the forward movement of the wiper arm in the Bosch type are controlled. 
         [0175]    The lower end portion of the head part body  310   a  of the connector is formed to be connected to one end  230  of the concave part  240 . 
         [0176]    In a case where the wiper arm  20  is coupled to the connector  300 , when the wiper arm  20  is coupled with and supported by the first coupling part or the second coupling part formed in sides of the connector  300 , the head part cover  310   b  forwardly and backwardly moves along one end  230  of the concave part  240  to restrain the front end of the wiper arm  20 . Accordingly, it is possible to prevent the wiper arm  20  from being, forwardly and upwardly separated. 
         [0177]    A method of separating the wiper arm  20  from the wiper blade assembly will be described. The head part cover  310   h  can forwardly move along the one end  230  of the concave part  240 . When the head part cover  311   b  of the connector  300  forwardly moves, the wiper arm  20  can be separated from the first coupling part  331  or the second coupling pan  332 .
