reference will now be made in detail to various embodiments of the present invention ( s ), examples of which are illustrated in the accompanying drawings and described below . while the invention ( s ) will be described in conjunction with exemplary embodiments , it will be understood that present description is not intended to limit the invention ( s ) to those exemplary embodiments . on the contrary , the invention ( s ) is / are intended to cover not only the exemplary embodiments , but also various alternatives , modifications , equivalents and other embodiments , which may be included within the spirit and scope of the invention as defined by the appended claims . a wiring holding flange and a manufacturing method thereof according to various embodiments of the present invention will now be described in detail with reference to fig4 to 7 . a wiring holding flange 100 according to various embodiments of the present invention is to firmly hold a wiring or hose 1 arranged on a chassis panel , and is formed in a “& lt ;” and “& gt ;” shape to hold the wiring or hose 1 by the flange 100 therein . more specifically , the wiring holding flange 100 includes , as shown in fig4 and 5 , a pair of connecting portions 110 integrally formed on a bottom surface of a chassis panel 200 , bent portions 120 formed on the connecting portions 110 and bent in left and right directions in the drawing , i . e ., in a “& lt ;” and “& gt ;” shape to hold the wiring or hose 1 , and support portions 130 formed on upper portions of the bent portions 120 for guiding the wiring or hose 1 therein and preventing release of the wiring or hose 1 therefrom when the wiring or hose 1 is held . the flange 100 including the connecting portions 110 , the bent portions 120 and the support portions 130 which are integrally formed has a narrow upper portion , a wide middle portion and a narrow lower portion . with this configuration , the wiring or hose 1 is easily inserted from the upper portion to the lower portion of the wiring holding flange 100 , and after the wiring or hose 1 is mounted , it is firmly held by the flange 100 in a left or right direction to prevent release of the wiring or hose 1 . a center bottom surface between the pair of the connecting portions 110 of the flange 100 is provided with a groove 140 for receiving the wiring or hose 1 therein , so that the groove 140 prevents movement of the wiring or hose 1 . preferably , the flange 100 has a resilient force to bias the wiring or hose 1 towards a center portion thereof , thereby preventing the movement of the wiring or hose 1 . a process of manufacturing the wiring holding flange according to various embodiments of the present invention will now be described with reference to fig6 and 7 . the process of manufacturing the wiring holding flange according to various embodiments of the present invention includes a cutting step s 10 , a bending step s 20 , and a forming step s 30 . a forging step s 25 may be provided between the bending step s 20 and the forming step s 30 . the cutting step 10 is to cut a portion of the chassis panel in a certain shape . more specifically , a portion of the chassis panel 200 , on which the wiring or hose 1 is disposed , is cut to form a pair of members 100 ′ in “[” and “]” shapes in accordance with a size of the flange 100 to be manufactured ( see fig7 a ). the pair of members 100 ′ are not limited to the “[” and “]” shapes , and may be formed in “& lt ;” and “& gt ;” shapes or in “(” and “)” shapes in accordance with a position of the flange . the bending step s 20 is to bend upwards the pair of members 100 ′ cut in the cut step around a portion which is integrally formed with the chassis panel 200 ( see fig7 b ). the forging step s 25 is to machine the groove 140 for receiving the wiring or hose 1 therein . more specifically , a portion of the chassis panel 200 between the pair of members 100 ′ is pressed downwards by using a pressing machine such as presser to form the groove 140 having a certain depth between the pair of members 100 ′, so that the wiring or hose 1 can be easily seated on the groove 140 ( see fig7 c ). the forming step s 30 is to form the flange 100 for holding the wiring by horizontally pressing the pair of members 100 ′ which are subjected to the forging step s 25 . more specifically , a first mold member 300 with a groove forming portion 311 is slid between the pair of members 100 ′ which are subjected to the forming step s 30 or the forging step s 25 ( see fig7 d ), and then second mold members 400 with a boss 410 closely contacting the groove forming portion 311 are slid towards both lateral sides of the first mold member 300 . the pair of members 100 ′ positioned between the groove forming portion 311 of the first mold member 300 and the bosses 410 of the second mold members 400 are pressed horizontally to form the flange 100 ( see fig7 e ). the first mold member 300 includes a vertical portion 310 with the groove forming portions 311 formed on both lateral sides thereof in a shape of flange 100 , and a horizontal portion 320 formed on the upper surface of the vertical portion 310 . bosses 410 of the second mold member 400 are received between the horizontal portion 320 and the vertical portion 310 . after the forming step s 30 is completed , the second mold members 400 and the first mold member 300 are successively removed , so that the pair of members 100 ′ is converted into the flange 100 for holding the wiring or hose 1 ( see fig7 f ). by forming the flange for holding the wiring using the above manufacturing process , a flange may be formed in an undercut shape . more specifically , if a pair of members is vertically stood on the chassis panel , it is impossible to form the flange using existing molds due to the undercut shape . however , the present invention can convert the pair of members into the flange 100 by moving the first mold member 300 and the second mold members 400 in two - way sliding manner , even though the pair of members is formed in the undercut shape . in various aspects of the present invention , it is possible to manufacture the wiring holding flange by integrally forming the flange on the chassis panel , thereby reducing a manufacturing cost thereof . for convenience in explanation and accurate definition in the appended claims ,
