     SUMMARY OF INVENTION 
     Technical Problems to be Solved 
     When functional parts such as rear combination lamps are to be provided along opposite side edges in the vehicle width direction of the tailgate, providing deflectors at opposite ends of the spoiler causes interference between the functional parts and the deflectors. Thus, the technique of Patent Literature 1 has a problem in that both of functional parts and deflectors cannot be provided in the rear part of a vehicle without interference with each other. 
     In view of the above, it is an object of the present invention to provide a structure of the rear part of a vehicle in which both of functional parts and deflectors can be provided without interference with each other. 
     Solution to Problem 
     To solve the above problem, an aspect of the present invention provides a structure of a rear part of a vehicle including a rear opening provided at a rear part of the vehicle, an openable and closable door for opening and closing the rear opening, a spoiler provided at an upper end portion of the door, a deflector provided below the spoiler, wherein the deflector extends downward from a lower surface of the spoiler along an outer surface of the door and is disposed at a position offset by a predetermined distance from an end in the vehicle width direction of the spoiler toward a central portion in the vehicle width direction of the spoiler. 
     According to this aspect of the present invention, the deflector is disposed at a position offset by a predetermined distance from an end in the vehicle width direction of the spoiler toward a central portion in the vehicle width direction of the spoiler. Thus, even when functional parts, such as rear combination lamps, are provided along opposite side edges in the vehicle width direction of the door, it is possible to avoid interference between the functional parts and the deflector. 
     In this case, the door may include a window opening, a window panel provided so as to cover the window opening, a functional part provided outside in the vehicle width direction of the window panel, wherein a lengthwise direction of the functional part extends along a side edge of the window panel. The deflector may be disposed at a position closer to a central portion in the vehicle width direction of the vehicle than an end of the functional part, which end is near the window panel. 
     According to this aspect of the present invention, the functional part and the deflector are not overlapped, and it is thereby possible to avoid impairing the function of the functional part even with the deflector being provided. 
     In this case, the functional part may further include a wind directing surface gradually protruding toward a vehicle rear direction with increasing distance from an outer side to a central portion in the vehicle width direction of the vehicle. The deflector may further include a guiding surface gradually protruding toward the vehicle rear direction with increasing distance from the outer side to the central portion in the vehicle width direction of the vehicle. The guiding surface and the wind directing surface may be arranged side by side in the vehicle width direction and formed respectively on the same side in the vehicle width direction of the functional part and the deflector. 
     According to this aspect of the present invention, the wind directing surface directs traveling wind toward the vehicle rear direction, and the guiding surface can prevent the traveling wind which has left the wind directing surface from being drawn back to the outer surface of the door. 
     In the above-mentioned cases, the door may include a window opening and a window panel provided so as to cover the window opening, and the deflector may be disposed at a position such that the deflector is overlapped with the window panel as viewed from the vehicle rear. 
     According to this aspect of the present invention, the deflector is disposed at a position such that the deflector is overlapped with the window panel as viewed from the vehicle rear. This makes it possible to manufacture a vehicle having the deflector and a vehicle not having the deflector, using the same window panel. 
     In this case, the structure for the rear part of a vehicle may further include an elastic member disposed between the deflector and the window panel. 
     According to this aspect of the present invention, the elastic member can prevent vibration of the deflector on the window panel and impact noise occurring between the deflector and the window panel. 
     In the above-mentioned cases, the spoiler may further include: a spoiler body whose surface forms at least a part of an upper surface of the spoiler and forms a part of a lower surface of the spoiler, the spoiler body having an opening formed in the lower surface; and a cover member covering a part of the opening of the spoiler body, and the deflector may cover a part of the remaining part of the opening of the spoiler body. 
     According to this aspect of the present invention, the cover member for covering the opening of the spoiler body can be of smaller dimensions since the deflector additionally covers the opening. 
     In this case, the deflector may further include: a fixed portion fastened to the spoiler body in a portion along an edge of the opening of the spoiler body; and, in a portion spaced apart from the edge of the opening of the spoiler body and adjoining to the cover member, an abutted portion on which the cover member abuts from the outside of the vehicle. 
     According to this aspect of the present invention, it is possible to attach the deflector to the spoiler body firmly by the fixed portion in the portion along the edge of the opening of the spoiler body. 
     In addition, even while the cover member is detached, the deflector can be held on the spoiler body by means of the fixed portion. 
     Further, in the portion of the deflector which portion is spaced apart from the edge of the opening and not fixed to the spoiler body by means of the fixed portion, the abutted portion can prevent the deflector from being displaced toward the outside of the vehicle. 
     Still further, the cover member merely abuts on the deflector at the abutted portion, thus providing the ease of attaching the cover member. 
     In this case, the abutted portion may be provided in the vicinity of the fixed portion. 
     This aspect of the present invention allows the cover member to support the deflector further firmly. 
     In the above-mentioned cases, the spoiler may further include: a spoiler body whose surface forms at least a part of an upper surface of the spoiler and forms a part of a lower surface of the spoiler, the spoiler body having an opening formed in the lower surface; and a cover member covering a part of the opening of the spoiler body, wherein the deflector is integrally formed with the cover member. 
     According to this aspect of the present invention, the deflector and the cover member are integrally formed. It is thereby possible to reduce the number of necessary component parts and the operating cost for attaching the deflector. 
     In addition, in contrast to the embodiment in which the deflector and the cover member are separated components, it is possible to indirectly support the deflector additionally at the portions of the spoiler body to which the cover member is attached, and thus fix the deflector firmly. 
     In this case, the spoiler body may further include a support portion which abuts and is in contact with the outer surface of the door in the vicinity of the deflector. 
     According to this aspect of the present invention, it is possible for the spoiler body to be firmly supported by the outer surface of the window panel of the door via the support portion in the vicinity of the deflector. This results in higher support rigidity of the deflector. 
     Also, it makes possible to prevent a collision between the spoiler and the deflector caused by flexure or the like of the spoiler body. 
     Advantageous Effect of Invention 
     According to the present invention, it is possible to provide a structure for a rear part of a vehicle in which both of functional parts and deflectors are provided without interference with each other.

     DESCRIPTION OF EMBODIMENTS 
     Now, embodiments of the present invention will be described with drawings. 
     First Embodiment 
     First of all, a structure for a rear part of a vehicle of a first embodiment of the present invention will be described.  FIG. 1  is a rear view of a vehicle  101  according to the first embodiment of the present invention.  FIG. 2  is an enlarged perspective view of a rear part  102  of the vehicle  101  according to the first embodiment of the present invention. The diagrams starting form  FIG. 1  show directions of the vehicle  101  (directions seen from a driver of the vehicle  101 ) as appropriately. 
     In the rear part  102  of the vehicle  101  according to the first embodiment, a rear opening  11  communicating with the vehicle interior is formed. The rear opening  11  is openable and closable by a tailgate  12 , which serves as an openable and closable door. In a state in which the tailgate  12  is closed, rear combination lights  13 , i.e., functional parts, are provided at opposite sides in the vehicle width direction of the rear part  102  of the vehicle  101 . The rear combination lights  13  include: a pair of rear combination lights  13   a  each of which is provided below a corresponding rear pillar  103 ; and the other pair of rear combination lights  13   b  each of which is for example provided at corresponding one of opposite sides in the vehicle width direction of the tailgate  12  above the corresponding rear combination light  13   a.    
     A spoiler (tailgate spoiler)  21  is provided at an upper end portion  14  of the tailgate  12 . The spoiler  21  rectifies traveling air blowing down from a roof  104  of the vehicle  101  so as to prevent the traveling air from being drawn to the rear part of the vehicle  101 . Below the spoiler  21 , deflectors  31  are provided. Each of the deflectors  31  rectifies traveling air blowing from a side surface  105  of the vehicle  101  so as to prevent the air from being drawn to the rear part of the vehicle. 
     Each of the deflectors  31  extends downward from a lower surface  22  of the spoiler  21  along an outer surface  15  of the tailgate  12 . The deflector  31  is disposed at a position offset by a predetermined distance from an end  23  in the vehicle width direction of the spoiler  21  toward a central portion in the vehicle width direction of the spoiler  21 . More specifically, the deflector  31  is disposed at a position closer to the central portion in the vehicle width direction of the vehicle than an end portion  45  of the corresponding rear combination light  13   b , which end portion  45  is near a window panel  17  (see also  FIG. 3 ). The tailgate  12  includes a window opening  16  and the window panel  17  provided so as to cover the window opening  16 . The rear combination light  13   b  is provided outside in the vehicle width direction of the window panel  17 . The lengthwise direction of the rear combination light  13   b  extends along a side edge  18  (see  FIG. 1 ) of the window panel  17 , and the deflector  31  is disposed at a position closer to the central portion than the side edge  18  in the vehicle width direction of the window panel  17 . 
     According to the above-described structure of the rear part  102  of the vehicle  101 , each of the deflectors  31  is disposed at a position offset by a predetermined distance from the corresponding end  23  in the vehicle width direction of the spoiler  21  toward a central portion in the vehicle width direction of the spoiler  21 . This allows an arrangement of the rear combination lights  13   b  along the side edges in the vehicle width direction of the tailgate  12  without causing interference between the rear combination lights  13   b  and the deflectors  31 . Thus, since the rear combination lights  13   b  and the deflectors  31  are not overlapped, a third person is able to recognize light emitting from the rear combination lights  13   b  even with the deflectors  31  being provided, and it is thereby possible to not impair the function of the lights. 
       FIG. 3  is an enlarged perspective view of the rear part  102  of the vehicle  101  partially cut away along the line III-III in  FIG. 2 . As shown in  FIG. 3 , on an outer surface of each of the rear combination lights  13   b , a wind directing surface  41  is formed gradually protruding toward a vehicle rear direction with increasing distance from an outer side to a central portion in the vehicle width direction of the vehicle. On the corresponding deflector  31 , a guiding surface  42  is formed gradually protruding toward the vehicle rear direction with increasing distance from the outer side to the central portion in the vehicle width direction of the vehicle. The wind directing surface  41  and the guiding surface  42  are arranged side by side in the vehicle width direction (see  FIGS. 2 and 3 ). The wind directing surface  41  and the guiding surface  42  arranged side by side in the vehicle width direction are formed respectively on the same side in the vehicle width direction of the rear combination light  13   b  and the deflector  31  (see  FIG. 3 ). 
     In the above-described structure of the guiding surface  42  and wind directing surface  41 , the wind directing surface  41  directs traveling wind toward the rear direction of the vehicle  101 , and the guiding surface  42  can prevent the traveling wind which has left the wind directing surface  41  from being drawn back to the outer surface  15  of the tailgate  12 . 
     Incidentally, the rear combination light  13   b  internally includes a light unit  43  for emitting light. The light unit  43  is provided in a flat portion  44 , which is located closer to the central portion in the vehicle width direction of the vehicle than the wind directing surface  41  as viewed from the vehicle rear side. The surface of the flat portion  44  is substantially parallel to the vehicle width direction. 
     The reason why the light unit  43  is provided at the location of the flat portion  44  rather than the wind directing surface  41  as viewed from the vehicle rear is that the light emitting from the flat portion  44  allows the rear combination light  13   b  to be seen more clearly than if light is emitted from the wind directing surface  41  having a slope in the vehicle width direction. 
     Also as shown in  FIG. 3 , the deflector  31  is disposed at a position such that the deflector  31  is overlapped with the window panel  17  as viewed from the vehicle rear. 
     Arranging the deflector  31  at a position such that the deflector  31  is overlapped with the window panel  17  as viewed from the vehicle rear enables manufacturing of a vehicle  101  having the deflector  31  and a vehicle  101  not having the deflector  31 , using the same window panel  17 . 
       FIG. 4  is an enlarged perspective view in which one of the deflectors  31  and a surrounding area of the deflector are viewed from a lower side.  FIG. 5  is a cross-sectional view taken along the line V-V in  FIG. 4 .  FIG. 6  is a view of the deflector  31  as viewed from the vehicle front. 
     As shown in  FIGS. 4 to 6 , an elastic member  51  is interposed between the deflector  31  and the window panel  17 . The elastic member  51  may be a sponge rubber attached to a vehicle front side of the deflector  31  so as to abut on the outer surface of the window panel  17 . Alternatively, the elastic member  51  may be a double-sided tape by which the vehicle front side of the deflector  31  is stuck to the outer surface of the window panel  17 . Alternatively, the elastic member  51  may be a surface fastener whose hook surface and loop surface are respectively stuck to the vehicle front side of the deflector  31  and the outer surface of the window panel  17  so that the deflector  31  is detachably supported by the window panel  17 . 
     Interposing the elastic member  51  between the deflector  31  and the window panel  17  as described makes it possible to prevent vibration of the deflector  31  on the window panel  17  and impact noise occurring between the deflector  31  and the window panel  17 . 
       FIG. 7  is a perspective view of the spoiler  21  and the deflectors  31  as viewed from the vehicle rear side. As shown in  FIG. 7 , the deflectors  31  are attached to the spoiler  21  (details described later). A high-mount stop lamp  61  is formed in a central portion in a lengthwise direction at a rear end edge in a vehicle front-rear direction of the spoiler  21 . 
       FIGS. 8 to 11  are diagrams showing the structure of the spoiler  21 . The spoiler  21  includes broadly a spoiler body  62  and a cover member  63 . The spoiler body  62  includes broadly an outer member  64  and an inner member  65 .  FIG. 8  is a drawing illustrating the outer member  64  as viewed from the bottom side of the vehicle.  FIG. 9  is a drawing illustrating the spoiler body  62  in which the inner member  65  is attached to the outer member  64 , as viewed from the bottom side of the vehicle. An upper surface  66  of the spoiler body  62  (outer member  64  of the spoiler body  62 ) forms at least a part, or whole in this example, of the upper surface  67  of the spoiler  21  (see  FIG. 7 ). Opposite end sides  68   a  in the vehicle width direction of a lower surface  68  of the spoiler body  62  (outer member  64  of the spoiler body  62 ) form parts of the lower surface  22  (see  FIGS. 1 and 2 ) of the spoiler  21 . The inner member  65  is a component of the spoiler  21 , in which component, bosses for attaching to the vehicle  101 , bosses for attaching the high-mount stop lamp  61 , and the like are collectively disposed. The spoiler body  62  in which the inner member  65  has been attached to the outer member  64  has a large opening  69  formed in the vehicle bottom side of the spoiler body  62  at a central portion in the vehicle width direction of the spoiler body  62 . The inner member  65  is exposed from the opening  69 . 
     The cover member  63  is attached to the spoiler body  62  so as to cover a part of the opening  69 , i.e., most of a central portion in the vehicle width direction of the opening  69  in this example. The deflectors  31  are attached to the spoiler body  62  so as to cover a part of the remaining part of the opening  69 , i.e., end portions opposite in the vehicle width direction of the opening  69  in this example.  FIG. 10  is a drawing illustrating a spoiler  21  in which the central portion in the vehicle width direction of the opening  69  of the spoiler body  62  of  FIG. 9  has been covered with the cover member  63  and the deflectors  31 , as viewed from the bottom side of the vehicle.  FIG. 11  is a drawing illustrating a spoiler  21  in which the central portion in the vehicle width direction of the opening  69  of the spoiler body  62  of  FIG. 9  has been covered only with the cover member  63 , as viewed from the bottom side of the vehicle. In the spoiler  21  shown in  FIG. 11 , the end portions (opening)  69   a  opposite in the vehicle width direction of the opening  69  are exposed because the deflectors  31  have not been provided. Incidentally, as shown in  FIGS. 10 and 11 , a recessed portion  70  is formed on the cover member  63  so as to accommodate a rear wiper not shown. 
     As described, in the spoiler  21 , the deflectors  31  cover the opening  69   a  of the spoiler body  62 , so that the cover member  63  for covering the opening  69  can be of smaller dimensions. As described, in the first embodiment, the opening  69  of the spoiler body  62  is entirely covered with the cover member  63  and a pair of deflectors  31 . 
     Next, the attaching structure of the deflectors  31  to the spoiler  21  will be described.  FIG. 12  is an enlarged perspective view of an attaching portion of the spoiler  21  for attaching one of the deflectors  31  to the spoiler  21 .  FIG. 13  is a cross-sectional view taken along the line XIII-XIII in  FIG. 12 . 
     The deflector  31  includes fixed portions  71  and  72 . The fixed portion  71  protrudes from a proximal end of a guiding surface forming plate  91 , which forms the guiding surface  42 , toward a central portion in the vehicle width direction of the vehicle. The guiding surface forming plate  91  is provided with a support plate  92  at an acute angle with the guiding surface forming plate  91 . The fixed portion  72  protrudes from a proximal end of the support plate  92  toward a central portion in the vehicle width direction of the vehicle. The fixed portions  71  and  72  are fastened to the spoiler body  62  (outer member  64  of the spoiler body  62 ) in a portion along an edge of the opening  69  ( 69   a ) by means of bolts not shown. Specifically, before attaching the cover member  63  to the spoiler body  62 , the deflector  31  is attached to the spoiler body  62  (outer member  64  of the spoiler body  62 ) at the fixed portions  71  and  72 . Then, the spoiler body  62  to which the deflector  31  has been attached but the cover member  63  has not been attached is mounted to the vehicle  101 . Next, the cover member  63  is attached to the spoiler body  62  which has been mounted to the vehicle  101  and to which the cover member  63  has not been attached. 
     When attaching the cover member  63  to the spoiler body  62 , as shown in  FIG. 13 , the cover member  63  is fastened to the spoiler body  62  (inner member  65  of the spoiler body  62 ) with a bolt not shown as indicated by the arrow  73 . In this operation, the cover member  63  is fixed to the spoiler body  62  in a state that an abutting portion  75  of the cover member  63  abuts on an abutted portion  76  of the deflector  31 . Namely, in a portion of the deflector  31  which portion is spaced apart from the edge of the opening  69  ( 69   a ) and not fixed to the spoiler body  62  by the fixed portions  71  and  72 , the abutted portion  76  is pressed by the abutting portion  75  of the cover member  63 . The abutted portion  76  is provided relatively close to the fixed portions  71  and  72  (see  FIG. 12 ). 
     This attaching structure enables the deflector  31  to be firmly attached to the spoiler body  62  (outer member  64  of the spoiler body  62 ) at the fixed portions  71  and  72  in the portion along the edge of the opening  69  ( 69   a ). 
     In addition, even while the cover member  63  is detached, the deflector  31  can be held on the spoiler body  62  by means of the fixed portions  71  and  72 . This makes it possible to mount to the vehicle  101  the spoiler body  62  to which the cover member  63  has not been attached, and then attach the cover member  63  to the spoiler body  62 . 
     Further, in the portion of the deflector  31  which portion is spaced apart from the edge of the opening  69  ( 69   a ) and not fixed to the spoiler body  62  by means of the fixed portions  71  and  72 , the abutted portion  76  prevents the deflector  31  from being displaced toward the outside of the vehicle. 
     Still further, at the abutted portion  76 , the cover member  63  merely abuts on the deflector  31  with no need of fastening with bolts or the like, thus providing ease of attaching the cover member  63 . 
     In addition, the abutted portion  76  is provided relatively close to the fixed portion  72 , allowing the cover member  63  to support the deflector  31  further firmly. 
     Second Embodiment 
     Next, a structure of a rear part of a vehicle according to a second embodiment of the present invention will be described.  FIG. 14  is a perspective view of a spoiler  21  and deflectors  31  according to the second embodiment as viewed from the rear side of the vehicle.  FIG. 15  is a perspective view of the spoiler  21  and the deflectors  31  according to the second embodiment as viewed from the front side of the vehicle. In the subsequent description, the same symbols as those in the above-described first embodiment will be assigned to denote components common to the first embodiment, and their detailed description will be omitted. 
     The spoiler  21  and the deflectors  31  according to the second embodiment differ from the first embodiment in that the deflectors  31  are integrally formed with a cover member  63 . 
     In the second embodiment, the deflectors  31  and the cover member  63  are integrally formed. It is thereby possible to reduce the number of necessary component parts and the operating cost for attaching the deflectors  31 . 
     In contrast to the first embodiment, in which the deflectors  31  and the cover member  63  are separated components, it is possible to indirectly support the deflectors  31  additionally at the portions of the spoiler body  62  to which the cover member  63  is attached, and thus fix the deflectors  31  thinly. 
       FIG. 16  is an enlarged vertical cross-sectional view taken along the line XVI-XVI in  FIG. 14 . The second embodiment also differs from the first embodiment in that the spoiler body  62  (outer member  64 ) further includes support portions  81  each of which abuts and is in contact with the outer surface of the window panel  17  of the tailgate  12  ( FIGS. 1 and 2 ) in the vicinity of the corresponding deflector  31 , and the deflector  31  covers the support portion  81 . 
     More specifically, a lower portion of the outer member  64  includes: a portion  82  extending diagonally downward such as to approach the rear part  102  of the vehicle; a portion  83  extending from a distal end of the portion  82  toward and substantially perpendicular to the window panel  17 ; and a portion  81  (support portion  81 ) extending in substantially parallel with the outer surface of the window panel  17  from a distal end of the portion  83  in a diagonally downward direction of the rear part  102  of the vehicle. Further, a rib  85 , which serves as a reinforcing member, is disposed in a recess  84  which is formed on the outer member  64  on the side of the deflector  31  and defined by the portion  82 , the portion  83 , and the support portion  81  of the outer member  64 . In addition, an elastic member  51  is interposed between the support portion  81  and the window panel  17 . The portion  82 , portion  83 , support portion  81 , and rib  85  are covered by the deflector  31 , which is formed integrally with the cover member  63 . 
     In the second embodiment, it is possible for the spoiler body  62  (outer member  64  of the spoiler body  62 ) to be firmly supported by the outer surface of the window panel  17  of the tailgate  12  via each of the support portions  81  in the vicinity of the corresponding deflector  31 . It is thereby possible to achieve high support rigidity of the spoiler body  62  and the deflectors  31 . The support rigidity can further be increased by disposing the ribs  85  as described above. 
     In addition, it is possible for the ribs  85  to prevent a collision between the spoiler body  62  (outer member  64  of the spoiler body  62 ) and the deflectors  31  caused by flexure or the like of the spoiler body  62  (outer member  64  of the spoiler body  62 ). 
     Further, the support portions  81  can be covered by the deflectors  31  so as to be invisible from the outside. 
     The configuration of the second embodiment other than the above is as same as the first embodiment, and thus detailed description is omitted. 
     The present invention is needless to say not limited to the above described embodiments, but including various variations. Each of the above described embodiments is merely an embodiment of the present invention.
