CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a national phase application of International Application No. PCT/JP2011/062110, filed May 26, 2011, and claims the priority of Japanese Application No. 2010-129309, filed Jun. 4, 2010, the content of both of which is incorporated herein by reference. 
         [0002]    The present invention relates to a garnish and a coupling structure. 
     
    
     BACKGROUND OF THE INVENTION 
       [0003]    A door frame that forms a window frame of a vehicle door includes a frame portion, which serves as a framework of the door frame, and a weather strip, which is secured to the frame portion. The weather strip seals the space between the frame portion and a vehicle body. 
         [0004]    Patent document 1 describes a door frame, as shown in  FIG. 5 , including a frame portion  90  formed by joining an inner sash  91  and an outer sash  92 . The inner sash  91  includes a base-like coupling portion  93 , and a coupling hole  93   a  extends through the coupling portion  93 . A weather strip  96  includes a coupling hole  97  facing toward the coupling hole  93   a . An engagement portion  99   a  of a clip  99  is inserted through the coupling hole  97  of the weather strip  96  and the coupling hole  93   a  to fasten the frame portion  90  and the weather strip  96 . 
         [0005]    Further, in the prior art, as shown in  FIGS. 6(   a ) to  6 ( c ), a door frame that joins a resin garnish  100 , in lieu of the outer sash  92 , to the inner sash  91  (frame portion) has been proposed. The resin garnish  100  forms a design surface at the outer side of the vehicle. A dedicated clip  101  secured to the garnish  100  is inserted into a coupling hole  102 , which is formed in the coupling portion  93  separately from the coupling hole  93   a , to fasten the garnish  100  and the inner sash  91 . 
         [0006]    However, in this case, the clip  101  becomes necessary in addition to the clip  99 . This increases the number of components. Further, as shown in  FIG. 6(   c ), the inner sash  91  is recessed from the outer side of the vehicle by an amount corresponding to the projection length of the coupling portion  93 , and the clip  101  is fixed to a garnish box  103 , which projects from the garnish  100  toward the inner side of the vehicle facing the coupling portion  93 . When, for example, load is applied from the outer side of the vehicle to the garnish  100 , the garnish box  103  may be broken due to interference with the inner sash  91 . Accordingly, the minimum thickness of the garnish box  103  and the garnish  100  has to be determined to ensure that the garnish box  103  has sufficient strength. This reduces the freedom of design. 
         [0007]    Referring to  FIG. 7 , patent document 2 describes a door frame that employs an aluminum inner sash  110  (frame portion) to reduce the weight. In this case, since the bending characteristics of aluminum is generally poor, the base-like coupling portion, which may be a bent portion, is omitted from the inner sash  110 . In other words, the resin garnish  116  and the inner sash  110  are joined without using a base-like coupling portion as the inner sash  110 . 
         [0008]    More specifically, the inner sash  110  includes a flat portion, which is free from bent parts and provided with an insertion hole  111 . A garnish  116  includes a coupling projection  117  inserted through the insertion hole  111 . A clip  119  is inserted through a coupling hole  122 , which extends through the weather strip  120  and an inner insert  121 , and inserted into a coupling hole  117   a  arranged in a front surface of the coupling projection  117  to fasten the inner sash  110  and the weather strip  120 . This allows for the fastening of the inner sash  110 , the weather strip  120 , and the garnish  116  without increasing the number of clips even while keeping the inner sash  110  flat.

       SUMMARY OF THE INVENTION 
       [0011]    For the following two reasons, the door frame of patent document 2 may have an insufficient sealing capability. This may result in water leakage. 
         [0012]    (1) The weather strip  120  includes a pressing portion  123  that surrounds the coupling projection  117  (insertion hole  111 ). To satisfy the sealing capability requirements, the pressing portion  123  is required to be arranged in close contact with the inner sash  110  so that the pressing portion  123  is compressed by a certain amount. Accordingly, a strong force is required to fasten the garnish  116  and the clip  119 . However, the resin garnish  116  cannot withstand a strong pressing force. This may deform or break the coupling projection  117 . Accordingly, the level of the force for joining the garnish  116  and the clip  119  is limited, and the sealing capacity is insufficient. 
         [0013]    To withstand the strong pressing, the rigidity of the garnish  116  may be increased. However, when increasing the rigidity of the garnish  116 , the thickness of the garnish  116  must be increased. This increases the projection length toward the outer side of the vehicle and enlarges a step formed between the garnish  116  and the door glass. As a result, the aesthetic appeal is adversely affected. Further, the amount of the used resin material increases, which raises costs. 
         [0014]    (2) The inner sash  110  and the weather strip  120  are indirectly pressed against each other through the garnish  116 . Thus, for example, coupling variations of the garnish  116  may change the pressing state and result in an insufficient sealing capacity. 
         [0015]    It is an object of the present invention to provide a coupling structure that ensures the level of the force fastening a weather strip and a frame portion required to increase the sealing capacity without increasing the number of components, while suppressing the force fastening a garnish and the frame portion and allowing for the coupling of the weather strip and garnish to the frame portion. 
         [0016]    To achieve the above object, one aspect of the present invention provides a resin garnish coupled to a door frame that forms a window frame of a vehicle door. The door frame includes a frame portion, which includes a coupling part having an insertion hole, and a weather strip, which is fastened to the frame portion by a clip. The clip is inserted into the weather strip and the insertion hole and hooked to the frame portion to fasten the weather strip to the frame portion. The garnish includes a garnish main body, which forms a design surface at an outer side of a vehicle, and a hooking projection, which projects from the garnish main body. The hooking projection is formed to be engaged with a hook arranged on the clip in a state inserted in the insertion hole to couple the garnish to the frame portion. 
         [0017]    A further aspect of the present invention provides a coupling structure that couples a weather strip and a resin garnish to a frame portion. The frame portion forms a framework of a door frame forming a window frame of a vehicle door and includes a coupling part having an insertion hole. The weather strip is coupled to the frame portion and includes a coupling hole opposed to the insertion hole. The resin garnish includes a garnish main body, which forms a design surface at an outer side of a vehicle, and a hooking projection, which projects from the garnish main body and is inserted into the insertion hole. The coupling structure further includes a clip. The clip is inserted into the coupling hole and the insertion hole and hooked to the frame portion to fasten the weather strip to the frame portion. The clip includes a hook engaged with the hooking projection that is inserted into insertion hole to fasten the frame portion to the garnish.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0025]    One embodiment of the present invention will now be described with reference to the drawings. 
         [0026]      FIG. 1  is a side view showing a vehicle door to which a coupling structure of the present embodiment is applied from an outer side in a widthwise direction of a vehicle (outer side of vehicle). As shown in the drawing, a vehicle door  1  supported at the side of a vehicle body (not shown) includes a lower part that defines a door main body  2 . The door main body  2 , which is formed by joining an outer door panel and an inner door panel (not shown), is a bag-shaped structure having an upper opening. The vehicle door  1  further includes a door window glass DW or the like that projects from and retracts into the upper opening. 
         [0027]    Further, the vehicle door  1  includes a door frame  5 , which is fixed to a top part of the door main body  2  and which forms a window frame of the vehicle door (i.e., frame of door window glass DW). The door frame  5  includes a frame portion  10  that forms the framework of the door frame  5 . The frame portion  10  includes a pillar portion  11 , which is located toward the rear of the vehicle, and an upper rim portion  12 , which is located toward the front of the vehicle. The pillar portion  11 , which extends in the heightwise direction of the vehicle, is fixed to the door main body  2  (e.g., inner door panel). The upper rim portion  12  is connected to the top end of the pillar portion  11 . The upper rim portion  12  extends to have a generally arch-shaped form. The vehicle door  1  of the present embodiment is a front door, and the upper rim portion  12  and pillar portion  11  of the frame portion  10  (door frame  5 ) are respectively arranged in correspondence with an A pillar and B pillar (center pillar) of the vehicle body. An elongated garnish  20 , which is molded from, for example, a resin material of acrylonitrile butadiene styrene (ABS) or the like is secured to the pillar portion  11 . The garnish  20  covers the pillar portion  11  from the outer side of the vehicle. 
         [0028]      FIG. 2(   a ) is an exploded perspective view showing the door frame  5  at the pillar portion  11 , and  FIG. 2(   b ) is a cross-sectional view of the door frame  5  taken along line IIb-IIb in  FIG. 1 . As shown in these drawings, the pillar portion  11  includes a base-like coupling part  13 , which is arranged at a top part of the pillar portion  11  to project toward the inner side of the vehicle. The coupling part  13  includes an insertion hole  14 , which is generally tetragonal (refer to  FIG. 3)  and extends through the coupling part  13  in the thicknesswise direction. The pillar portion  11  is formed by, for example, pressing a steel plate. 
         [0029]    A weather strip  30 , which is secured to the pillar portion  11  (frame portion  10 ), is, for example, molded from an elastic material of rubber or the like. The weather strip  30  includes a hollow seal  31 , which has a generally uniform cross-section and generally extends along the entire length of the frame portion  10 , and a planar coupling wall  32 , which is formed integrally with the seal  31  in conformance with the top part of the pillar portion  11 . When the vehicle door  1  is fully closed, the weather strip  30  seals the space between the frame portion  10  and the vehicle body as the seal  31  elastically contacts the vehicle body generally throughout the entire length of the frame portion  10 . 
         [0030]    An insert  34  formed by, for example, a metal plate is embedded in the coupling wall  32 . The coupling wall  32  includes a coupling hole  33 , which faces the insertion hole  14  of the pillar portion  11 . The coupling hole  33  has a stepped form and includes a circular attachment hole  33   a , which is arranged at the side that is farther from the pillar portion  11 , and an insertion hole  33   b , which has a smaller diameter than the attachment hole  33   a  and faces pillar portion  11  (insertion hole  14 ). 
         [0031]    The garnish  20  includes an elongated garnish main body  21 , which forms a design surface at the outer side of the vehicle, and a hooking projection  22 , which projects integrally from the garnish main body  21  facing the insertion hole  14  of the pillar portion  11 . When securing the garnish  20  to the pillar portion  11 , the hooking projection  22  is inserted into the insertion hole  14 . 
         [0032]    As shown in  FIGS. 3(   a ) to  3 ( c ), the hooking projection  22  includes two generally planar support walls  23 , which extend from the garnish main body  21  spaced apart in a widthwise direction of the garnish main body  21  (corresponding to front to rear direction of the vehicle), and two connecting walls  24 , which connect distal ends of the two support walls  23 . The support walls  23  and the connecting walls  24  form a generally tetragonal frame that defines a hooking hole  25  at a distal part of the hooking projection  22 . When the hooking projection  22  (two support walls  23 ) is inserted into the insertion hole  14 , the hooking hole  25  is arranged on the pillar portion  11  at the opposite side of the garnish main body  21  (refer to  FIG. 2(   b )). The hooking hole  25  opens in the same direction as the insertion hole  14  at a central part of the insertion hole  14  (refer to  FIG. 3(   b )). The parts of the insertion hole  14  at the upper side and lower side of the hooking hole  25  form openings  27  defined by the support walls  23  and the connecting walls  24 . 
         [0033]    Generally, to prevent sink marks during resin molding, the minimum thickness of the garnish main body  21  is required to be determined in accordance with the thickness of the support walls  23 . In the present embodiment, a step  23   a  (refer to  FIG. 3(   c )) is arranged at the basal side (toward garnish main body  21 ) of each support wall  23  so that the width at the basal side of the support wall  23  is smaller than the width at the distal side. This reduces the limitation on the minimum thickness of the garnish main body  21  and eliminates the need to increase the thickness of the garnish main body  21 . Further, the support walls  23  include outer surfaces  23   b  (surfaces of the two support walls  23  facing opposite directions), each provided with two streaks of ribs  26 , which function as a first rib and a second rib and which are located at positions conforming to the connecting walls  24  as viewed from beside (refer to  FIG. 3(   b )). In this manner, the two ribs  26  are formed on each of the two support walls  23  intersecting the outer surface  23   b  of the support wall  23  at a generally right angle (widthwise direction of the garnish main body  21 ) and projects away from the other one of the support walls  23 . Each rib  26  is connected to the support wall  23  and the garnish main body  21  and reinforces the part of the support wall  23  connected to the garnish main body  21 . Further, each rib  26  extends in the extending direction of the support wall  23  and reinforces the outer surface  23   b  of the support wall  23 . 
         [0034]    Each rib  26  has a generally constant projection length generally throughout the entire length in the extending direction of the support wall  23 . The distance between outer surfaces  26   a  of the ribs  26  opposed in the opposing direction (widthwise direction of the garnish main body  21 ) of the two support walls  23  is constant in a range covering at least part of the support walls  23  in the extending direction. The constant distance between the outer surfaces  26   a  is generally the same as the opening width of the insertion hole  14  in the widthwise direction (refer to  FIG. 3(   b )). Thus, even when manufacturing dimension variations or coupling variations change the insertion position of the support walls  23  (hooking projection  22 ) relative to the insertion hole  14  within the range in the extending direction of the support walls  23 , the positioning accuracy of the hooking projection  22  relative to the insertion hole  14  can be kept at a generally constant and high level. 
         [0035]    A distal part of the rib  26 , which is farthest from the garnish main body  21 , is diagonally cut. This forms a guide  26   b  that guides the insertion of the hooking projection  22  into the insertion hole  14 . 
         [0036]    As shown in  FIGS. 2(   a ) and  2 ( b ), a clip  40 , which is inserted through the coupling hole  33  of the weather strip  30 , is engaged with the pillar portion  11  and the garnish  20 . The clip  40  is formed from an elastic resin material such as polypropylene (PP) or polyacetal (POM). The clip  40  includes a generally disk-shaped head portion  41 , which has a larger outer diameter than the inner diameter of the attachment hole  33   a , and a generally cylindrical attachment portion  42 , which has generally the same outer diameter as the inner diameter of the attachment hole  33   a . The clip  40  further includes two frame portion hooks  43  projecting from an upper part and lower part of the attachment portion  42  toward the garnish main body  21 . The frame portion hooks  43  are respectively inserted into the openings  27  defined at the upper side and lower side of the hooking hole  25 . When the attachment portion  42  is attached to the attachment hole  33   a  in the coupling hole  33 , the distal ends of the two frame portion hooks  43  are inserted through the insertion hole  33   b  and the insertion hole  14  (openings  27 ) and hooked to the rim of the insertion hole  14 . This engages the clip  40  with the pillar portion  11 . In this state, the clip  40  sandwiches the weather strip  30  and the pillar portion  11  between the head portion  41  and the distal ends of the two frame portion hooks  43  thereby fastening the weather strip  30  and the pillar portion  11 . The fastening force between the weather strip  30  and the pillar portion  11  is set at a level that is sufficient for maintaining the sealing capability at the pressed contact surface between the weather strip  30  and the pillar portion  11 . 
         [0037]    Further, the clip  40  includes a garnish hook  44  projecting from a central part of the attachment portion  42  and inserted into the hooking hole  25 . When the attachment portion  42  is attached to the attachment hole  33   a  of the coupling hole  33 , the distal end of the garnish hook  44  is hooked to the rim of the hooking hole  25  (upper connecting wall  24  in  FIG. 2(   b )). This engages the clip  40  with the garnish  20 . In this state, the clip  40  pulls the connecting walls  24  (hooking projection  22 ) toward the weather strip  30  thereby fastening the pillar portion  11  and the garnish  20 . The fastening force between the pillar portion  11  and the garnish  20  is, for example, suppressed at the minimum level required to prevent separation of the garnish  20 . The fastening force (binding force) between the pillar portion  11  and the garnish  20  is complemented by the adhesive force of a double-sided tape (not shown) applied between the pillar portion  11  and the garnish  20 . Further, the adhesion of the pillar portion  11  and the garnish  20  with the double-sided tape prevents swaying about the insertion hole  14  (hooking projection  22 ). 
         [0038]    The present embodiment has the advantages described below. 
         [0039]    (1) In the present embodiment, the garnish hook  44  is hooked to the hooking projection  22  inserted into the insertion hole  14 . As a result, the garnish  20  is engaged with the clip  40 , pulled by the clip  40 , and fastened to the pillar portion  11  (frame portion  10 ). In this manner, the garnish  20  and the pillar portion  11  are fastened using the clip  40 , which fastens the weather strip  30  and the pillar portion  11 . This allows for the number of components to be decreased and thereby reduces costs. Further, the fastening force (pulling force) related with the sealing capability produced between the weather strip  30  and the pillar portion  11  by the clip  40  is set independently from the fastening force produced between the garnish  20  and the pillar portion  11  by the clip  40 . Thus, for example, the fastening force between the pillar portion  11  and the weather strip  30  can be sufficiently ensured to improve the sealing capability without increasing the fastening force between the garnish  20  and the pillar portion  11 . Further, the fastening force (pulling force) between the garnish  20  and the pillar portion  11  can be suppressed to, for example, the minimum level that prevents separation of the garnish  20  without decreasing the fastening force between the weather strip  30  and the pillar portion  11 . This allows for the rigidity of the hooking projection  22  to be lowered thereby allowing for a further decrease in the thickness of the hooking projection  22  and the garnish main body  21 . 
         [0040]    (2) In the present embodiment, the two support walls  23  are each reinforced by the ribs  26 . This allows for a further decrease in the thickness of the support walls  23 . 
         [0041]    (3) In the present embodiment, the ribs  26  (first rib) reinforce the part of the support walls  23  connected to the garnish main body  21 . This prevents the support wall  23  from leaning without increasing the thickness. Further, the ribs  26  (second rib) reinforce the outer surfaces  23   b  of the support walls  23 . This prevents deformation of the support walls  23 . 
         [0042]    (4) In the present embodiment, the ribs  26  (first rib) that reinforce the part of the support walls  23  connected to the garnish main body  21  also function as the ribs  26  (second rib) that reinforce the outer surfaces  23   b  of the support walls  23 . In other words, the first rib is integrated with the second rib. This simplifies the shape of the hooking projection  22  (support walls  23 ) in comparison to, for example, when arranging separate first and second ribs on each support wall  23 . 
         [0043]    (5) In the present embodiment, the distance between the outer surfaces  26   a  of the opposing ribs  26  is constant in a range covering at least part of the support walls  23  in the extending direction. Accordingly, even when manufacturing dimension variations or coupling variations change the insertion position of the support walls  23  (hooking projection  22 ) relative to the insertion hole  14  within the range in the extending direction of the support walls  23 , the positioning accuracy of the hooking projection  22  relative to the insertion hole  14  can be kept at a generally constant level. 
         [0044]    (6) In the present embodiment, the guides  26   b  of the ribs  26  guide the insertion of the hooking projection  22  into the insertion hole  14 . This allows for smooth insertion of the hooking projection  22  into the insertion hole  14 . In particular, even when the positioning accuracy of the insertion hole  14  and the hooking projection  22  is kept at a high level so that the opening width of the insertion hole  14  is set to be generally the same as the distance between the outer surfaces  26   a  of the opposing ribs  26  and play between the wall of the insertion hole  14  and the hooking projection  22  is subtle or null, the hooking projection  22  can be smoothly inserted into the insertion hole  14 . 
         [0045]    (7) The present embodiment omits the clip dedicated for fastening the garnish  20  and the pillar portion  11 . Thus, there is no need to cover a clip with the coupling wall  32  of the weather strip  30 , and the coupling wall  32  (corner in the weather strip  30 ) can be further reduced in size. 
         [0046]    (8) In the present embodiment, the pillar portion  11  is fastened to the weather strip  30  in the proximity of the insert  34 . This further stabilizes the sealing capability. 
         [0047]    (9) In the present embodiment, by decreasing the thickness of the garnish main body  21 , the step formed with the door window glass DW can be reduced in size. This prevents the aesthetic appeal from being adversely affected by the step and suppresses wind roar. 
         [0048]    The above embodiment may be modified as described below. 
         [0049]      FIGS. 4(   a ) to  4 ( c ) show a hooking projection  51  that can be employed. Specifically, the hooking projection  51  includes two support walls  52  inclined relative to the garnish main body  21  to become closer to each other toward their distal ends (refer to  FIG. 4(   c )). Further, each support wall  52  includes a step  52   a  at a part near its basal end (part near garnish main body  21 ), and the part near the basal end of the support wall  52  has a smaller width than other parts. Additionally, the support walls  52  include outer surfaces  52   b  (surfaces of the two support walls  23  facing opposite directions), each provided with streaks of second ribs  53 , which are located at positions corresponding to the connecting walls  24  as viewed from beside (refer to  FIG. 4(   b )). In this manner, the second ribs  53  are formed on each of the two support walls  52  in a direction intersecting the outer surface  52   b  of the support wall  52  at a generally right angle (widthwise direction of the garnish main body  21 ) and projects away from the other one of the support walls  52 . Each second rib  53  extends in the extending direction of the support wall  52  and reinforces the outer surface  52   b  of the support wall  52 . 
         [0050]    Further, each second rib  53  is formed so that the projection length of the second rib  53  gradually increases from the basal side to the distal side of the support wall  52 . In the projection direction, each second rib  53  includes an outer surface  53   a  that extends in a direction orthogonal to the garnish main body  21 . Accordingly, the distance between the outer surfaces  53   a  of the second ribs  53  opposed in the opposing direction (widthwise direction of the garnish main body  21 ) of the two support walls  52  is constant in a range covering at least part of the support walls  52  in the extending direction. The constant distance between the outer surfaces  53   a  is generally the same as the opening width of the insertion hole  14  in the widthwise direction (refer to  FIG. 4(   b )). Thus, even when manufacturing dimension variations or coupling variations change the insertion position of the support walls  52  (hooking projection  51 ) relative to the insertion hole  14  in the extending direction of the support walls  52  within the range, the positioning accuracy of the hooking projection  51  relative to the insertion hole  14  can be kept at a generally constant and high level. In this case, the width at the basal end of each support wall  52  does not increase even at where the second ribs  53  are located. Accordingly, even when the second ribs  53  are molded, the formation of sink marks is suppressed at the basal end of each support wall  52  where the second rib  53  are located. This allows for the garnish main body  21  to remain thin even at where the second ribs  53  are located. A distal part of the second rib  53 , which is farthest from the garnish main body  21 , is diagonally cut. This forms a guide  53   b  that guides the insertion of the hooking projection  51  into the insertion hole  14 . 
         [0051]    Further, each support wall  52  includes two planar first ribs  54  formed at parts connected to the garnish main body  21 . The first ribs  54  of each support wall  52  project in directions opposite to the first ribs  54  of the other support wall  52 . Specifically, the two first ribs  54  formed on each of the two support walls  52  project away from the first ribs  54  of the other support wall  52  in a direction intersecting the outer surface  52   b  of the support wall  52  at a generally right angle. The first ribs  54  are formed at the top end and bottom end of each support wall  52 . Each first rib  54  reinforces the part of the support wall  52  connected to the garnish main body  21 . This prevents the two support wall  52  from leaning without increasing the thickness. In addition, the first ribs  54  gradually increase the connection area of the garnish main body  21  and the hooking projection  51 , and the shape of the part connecting each support wall  52  and the garnish main body  21  becomes two-dimensional. As a result, the tensile strength between each support wall  52  and the garnish main body  21  can be increased. In this case, there is no need to increase the thickness of each support wall  52 . Thus, for example, there is no need to increase the thickness of the garnish main body  21  to prevent sink marks, and the garnish main body  21  can be further reduced in thickness. 
         [0052]    The modified embodiment has advantages (1) to (3) and (5) to (9) of the above embodiment. In particular, the first and second ribs  54  and  53  are arranged separately on each support wall  52 . This reduces limitations on the shape of the second ribs  53  caused by the first ribs  54 . Thus, the projection length of the second ribs  53  can be set to be subtle or null at the parts of the support walls  52  connected to the garnish main body  21 . Thus, even when using the second ribs  53 , there is no need to increase the thickness of the support walls  52  at the connecting parts, and the formation of sink marks during resin molding can be suppressed. 
         [0053]    In the above embodiments, the guides that guide the hooking projections  22  and  51  to the insertion hole  14  are formed in the ribs  26  and  53 . Instead or in addition, the guides may be formed on the support walls  23  and  52 . 
         [0054]    In the above embodiment, the number and arrangement of the first ribs  54  on each support wall  52  are just examples. Further, the first ribs  54  formed on each of the two support walls  52  only need to be projected in a direction intersecting the outer surface  52   b  of the support wall and, for example, may be projected toward the other support wall  52 . 
         [0055]    In the above embodiments, the shape of the clip  40  is just one example. For example, the number of the frame portion hooks  43  used to fasten the pillar portion  11  and the weather strip  30  may be one, three, or more. Further, the distal end of the garnish hook  44  used to fasten the pillar portion  11  and the garnish  20  may be hooked to the lower connecting wall  24  instead of or in addition to the upper connecting wall  24 . 
         [0056]    In the above embodiment, the insertion hole  14  of the pillar portion  11  and the hooking projections  22  and  51  inserted into the insertion hole  14  are arranged at the top part of the pillar portion  11  and the like (corner of door frame  5 ). Instead or in addition, a hooking projection may be arranged at a bottom part of the pillar portion  11  or the like. 
         [0057]    In the above embodiment, the garnish  20  is attached to the pillar portion  11  of the frame portion  10 . However, the present invention may also be applied to a garnish that is attached to the upper rim portion  12 . 
         [0058]    The present invention may be applied to, for example, a door frame of a rear door.
