Description:
TECHNICAL FIELD 
     This invention relates to a wire cabling device configured to cable a wire between a vehicle body and a sliding object slidably mounted on the vehicle body, and to a method for manufacturing the wire cabling device. 
     BACKGROUND ART 
     For example, a seat as a sliding object slidable relative to a floor of a cabin as a vehicle body may be mounted on a vehicle. An electronic device such as a seating sensor for detecting whether a crew member is seated or not may be attached to the seat. For this reason, various wire cabling devices for cabling a wire between the floor and the seat are used in the vehicle in order to connect the electronic device attached to the seat to the electronic device fixed to the floor (for example, see Patent Document 1). 
       FIG. 8  is a perspective view showing a conventional wire cabling device.  FIG. 9  is an exploded view of the wire cabling device shown in  FIG. 8 .  FIG. 10  is a sectional view taken on line E-E of  FIG. 8 .  FIG. 11  is an explanatory view for explaining a mounting condition of a pair of conventional wire cabling devices mounted on a vehicle body. 
     A conventional wire cabling device  201  shown in  FIGS. 8 to 10  is a device configured to cable an electric wire  250  between a floor  202  of a cabin of a vehicle as a vehicle body, and a seat  203  as a sliding object slidably arranged along an arrow K 2  on the floor  202 . This wire cabling device  201  includes: the electric wire  250  for connecting the electronic device attached to the floor  202  to the electronic device attached to the seat  203 ; a case  205  receiving the electric wire  250 ; a rail  211  formed on an inside of the case  205 ; a first protector  206  and a second protector  230  for moving in linkage with the seat  203  on a rail  211 . 
     The case  205  is formed by a lower case  209  and an upper case  210  overlapped with each other, and has a tubular shape. The lower case  209  and the upper case  210  are made of a thick metal plate. The case  205  is fixed to the floor  202  with such as a bolt  212 , while a bottom wall  209   a  (see  FIG. 10 ) abuts on the floor  202 . A regulation part  290  is integrally formed with the lower case  209  by embossing a part of the bottom wall  209   a  toward the upper case  210 . This regulation part  290  regulates a cabling route of the electric wire  250  in the case  205  into a U-shape by partitioning a space in the case  205 . A slit  225  extended along the arrow K 2  for guiding the first protector  206  from an inside of the case  205  to an outside of the case  205  is formed on the case  205  (see  FIG. 10 ). Further, a mall  207  is attached around the slit  225  for preventing a foreign particle from entering the case  205  via the slit  225 . 
     Because the case  205  is disposed under the seat  203 , and as shown in  FIG. 10 , hidden under a mat  228 , the crew member of the vehicle often stamps the case in an arrow F 2  direction toward the floor  202 . Therefore, for preventing the case  205  from being deformed or damaged when the case  205  is stamped, the rigidity of the case  205  is improved by thickening a thickness of the case  205 , by arranging concave portions  243  and convex portions  242  alternately along the arrow K 2  on a ceiling wall of the upper case  210  in a bead shape, or by bolting a plurality of positions of the case  205  to the floor  202 . 
     A middle part of the electric wire  250  is received in the case  205 , and arranged in a U-shape by the regulation part  290 . An end of the electric wire  250  near the seat  203  is held by the first protector  206 . The electric wire  250  is guided from the case  205  via the slit  225  to an outside of the case  205 , namely, to the seat  203  side. Further, the other end of the electric wire  250  at the floor  202  side is guided from an end  205   a  of the case  205  to the outside of the case  205 . 
     Further, a reference sign  204  in  FIG. 9  indicates a corrugate tube for protecting the electric wire  250 . Further, the second protector  230  is attached to the seat  203 , and coupled to the first protector  206  with a cord. 
     As shown in  FIG. 11 , such a wire cabling device  201  is attached to the floor  202 , and arranges the electric wire  250  to a front passenger&#39;s seat  203  of a vehicle. In the wire cabling device  201 ′ arranging the electric wire  250  to a driver&#39;s seat  203 , the case  205  is designed to have a line symmetric shape along a width direction H 2  of the wire cabling device  201  and the vehicle.

     SUMMARY OF INVENTION 
     Technical Problem 
     Although the cases  205  of the wire cabling device  201  and the wire cabling device  201 ′ include the regulation part  290  integrally formed with the lower case  209  and the bead shape composed of the concave portions  243  and convex portions  242 , and have the symmetric shape along the width direction H 2  of the vehicle, the case  205  having the same shape cannot be commonly used in the wire cabling device  201  and the wire cabling device  201 ′ because a sectional shape of the case  205  along the sliding direction of the seat  203  is not constant. Namely, the case  205  of the wire cabling device  201  cannot be used as the case  205  of the wire cabling device  201 ′ by rotating the case  205  180 degree. Therefore, two types of dedicated metal molds are needed for the case  205  of the wire cabling device  201  and the case  205  of the wire cabling device  201 ′, and there is a problem that a production cost increases. 
     Further, as described above, because the sectional shape of the case  205  along the sliding direction of the seat  203  is not constant in the wire cabling device  201  and the wire cabling device  201 ′, there is a problem that these cases  205  cannot be made by roll forming or extrusion molding having high productivity, and must be made by press molding of which production cost is high. 
     Accordingly, an object of the present invention is to provide a wire cabling device which a case can be shared among a plurality of cable wiring devices for cabling electric wires to a plurality of sliders provided on the right and left sides of a vehicle, and to provide a method for manufacturing the wire cabling device. 
     Solution to Problem 
     For attaining the object, according to the invention described in claim  1 , there is provided a wire cabling device comprising: 
     a case configured to receive a middle part of an electric wire arranged between a vehicle body and a sliding object slidably mounted on the vehicle body, and configured to be attached to the vehicle body, 
     a slider capable of moving in linkage with the sliding object on a rail attached to the case while holding the electric wire, 
     a regulation member which is provided in the case and regulates a cabling route of the electric wire in the case by partitioning the case, 
     wherein the case is formed in a tubular shape having a constant sectional shape along a sliding direction of the sliding object, and 
     wherein the regulation member is formed independently from the case. 
     According to the invention described in claim  2 , there is provided the wire cabling device as claimed in claim  1 , 
     wherein regulation member attaching parts capable of attaching the regulation member are provided on two places, one end and the other end of the case in the sliding direction. 
     According to the invention described in claim  3 , there is provided the wire cabling device as claimed in claim  1  or  2 , 
     wherein the regulation member is formed in a plane-symmetrical shape relative to a virtual plane passing the center of the regulation member and perpendicular to the sliding direction. 
     According to the invention described in claim  4 , there is provided the wire cabling device as claimed in any one of claims  1  to  3 , 
     wherein the case includes: a bottom wall having a gap with the vehicle body; and a ceiling wall facing the bottom wall, and 
     wherein the case further includes a pair of caps respectively attached to both ends of the case, said caps having a ceiling wall abutting part abutting on an inner surface at the bottom wall side of the ceiling wall, and a vehicle body abutting part abutting on the vehicle body. 
     According to the invention described in claim  5 , there is provided a method for manufacturing a wire cabling device including: a case for receiving an electric wire; a slider capable of moving on a rail attached to the case while holding the electric wire; and a regulation member for regulating a cabling route of the electric wire in the case by partitioning the case, 
     said method comprising the steps of 
     forming the case in a tubular shape having a constant sectional shape along a sliding direction of the slider; 
     producing the regulating member independent from the case; and 
     attaching the regulation member to the case at an attaching position properly changeable along the sliding direction. 
     Advantageous Effects of Invention 
     According to the invention claimed in claim  1 , because the regulation member is formed independently from the case, the shape of the case can be a tubular shape having a constant sectional shape along the sliding direction of the sliding object. Therefore, in a plurality of wire cabling devices respectively cabling electric wires to a plurality of sliding objects provided on the right and left sides of a vehicle, the case at the right side of the wire cabling device can be rotated 180 degree to be used as the case at the left side of the wire cabling device. Further, these cases can be made by roll forming or extrusion molding having high productivity. Resultingly, a cost of the wire cabling device can be reduced, and a production cost of the case can be reduced. 
     According to the invention claimed in claim  2 , because regulation member attaching parts capable of attaching the regulation member are provided on two places, one end and the other end of the case in the sliding direction, in a plurality of wire cabling devices respectively cabling electric wires to a plurality of sliding objects provided on the right and left sides of a vehicle, it is unnecessary to respectively provide the regulation member attaching parts to the cases independently. Therefore, the production cost of the case can be further reduced. 
     According to the invention claimed in claim  3 , because the regulation member is formed in a plane-symmetrical shape relative to a virtual plane passing the center of the regulation member and perpendicular to the sliding direction, in a plurality of wire cabling devices respectively cabling electric wires to a plurality of sliding objects provided on the right and left sides of a vehicle, not only the case but also the regulation member can be commonly used. Therefore, the cost of the wire cabling device can be further reduced. 
     According to the invention claimed in claim  4 , because the case includes: a bottom wall having a gap with the vehicle body; and a ceiling wall facing the bottom wall, and the case further includes a pair of caps respectively attached to both ends of the case, and the caps have a ceiling wall abutting part abutting on an inner surface at the bottom wall side of the ceiling wall, and a vehicle body abutting part abutting on the vehicle body, when a load is applied to the case from the ceiling wall to the bottom wall by such as stamping the case, the caps work as supports, and the load is not applied to the bottom wall, and transmitted to the vehicle body via the caps, thereby the stress generated in the case is reduced. Therefore, the rigidity capable of sufficiently enduring the load can be attained using the case and the pair of caps made by a process having high productivity such as roll forming or extrusion molding without providing a bead shape (namely, convexes and concaves made by press working) for increasing the rigidity which is provided in a conventional case by press working. Further, because a thickness of the case can be reduced, the case can be lighter, and a material cost can be reduced. Further, because the number of bolting positions for preventing the case from being deformed by the load can be further reduced than the conventional case, design flexibility of the case is increased, and man-hours for bolting the case can be reduced. Further, when convexes and concaves of which shapes depend on a car type are formed on a surface of the vehicle body to which the case is attached, because the case is disposed with a gap from the vehicle body, it is unnecessary to design the bottom wall in order to fit the convexes and the concaves, and only the vehicle body abutting part is designed in order to fit the concaves and the convexes. Therefore, the case can be commonly used in different car types. 
     According to the invention claimed in claim  5 , there is provided a method for manufacturing a wire cabling device including: a case for receiving an electric wire; a slider capable of moving on a rail attached to the case while holding the electric wire; and a regulation member for regulating a cabling route of the electric wire in the case by partitioning the case, said method comprising the steps of forming the case in a tubular shape having a constant sectional shape along a sliding direction of the slider; producing the regulating member independent from the case; and attaching the regulation member to the case at an attaching position properly changeable along the sliding direction. Therefore, in a plurality of wire cabling devices respectively cabling electric wires to a plurality of sliding objects provided on the right and left sides of a vehicle, the case at the right side of the wire cabling device can be rotated 180 degree to be used as the case at the left side of the wire cabling device.

Further, the arrow K extends straight in a longitudinal direction of the vehicle. 
     Electronic devices such as a seating sensor for detecting whether a crew member is seated or not, a seat belt sensor for detecting whether a seated crew member fastens a seat belt or not, or the like are mounted on the seat  3 . 
     The wire cabling device  1  includes: a plurality of electric wires  50 ; a container  100  for receiving a middle part of the electric wires  50 ; a pair of brackets  65 ,  75  respectively attached to an one end  5   a  and the other end  5   b  of a case  5  of the container  100  for fixing the case  5  to the floor  2 ; a regulation member  90  provided in the case  5 ; a rail  11  provided in the case  5 ; a plurality of mall brackets  8  attached to the case  5 ; a pair of malls  7   a ,  7   b  attached to the case  5 ; a first protector  6  and a second protector  30  as a slider capable of moving in linkage with the seat  3  on the rail  11 . 
     Each electric wire  50  is a so-called covered electric wire having a conductive core wire and an insulating cover. These electric wires  50  connect the above-described electronic devices attached to the seat  3  to the electronic devices such as an ECU (Electronic Control Unit) attached to the floor  2 . Further, these electric wires  50  are bundled and inserted into a corrugate tube  4  (see  FIG. 3 ). The corrugate tube  4  is made of synthetic resin such as polypropylene, and formed in a bellows tube shape. The corrugate tube  4  protects the electric wires  50  by receiving the electric wires  50  therein. 
     As shown in  FIGS. 1 and 2 , the container  100  includes: a tubular case  5  of which one end  5   a  in the longitudinal direction the electric wires  50  are guided out from; a cap  60  attached to the one end  5   a  of the case  5 ; and a cap  70  attached to the other end  5   b  of the case  5 . Further, the case  5  includes: a lower case  9 ; and an upper case  10  fixed to the lower case  9  with a bolt or the like while overlapped with the lower case  9 . 
     The lower case  9  is made of a metal plate, and formed in a rectangular shape in a plan view, of which longitudinal direction is parallel to the arrow K. Namely, a width direction of the lower case  9  is parallel to a width direction H (see  FIGS. 6 and 7 ) of the vehicle. As shown in  FIGS. 4 and 5 , this lower case  9  includes: a plate-shaped bottom wall  9   a  disposed on the floor  2  with a gap; an inner edge wall  9   b  vertically extending from an edge of the bottom wall  9   a  positioned inside (right side in  FIG. 4 ) of the cabin, and forming a slit  25  between the rail  11  and a later-described inner edge  10   f  of the upper case  10 ; a second outer edge wall  9   e  vertically extending from an edge of the bottom wall  9   a  positioned at an outside (left side in  FIG. 4 ) of the cabin; an outer edge  9   c  continued from a top end of the second outer edge wall  9   e  away from the bottom wall  9   a , and extending in a plate shape toward an outside of the cabin; and a rail attaching part  9   d  disposed on the bottom wall  9   a  at an inner side of the cabin, and with which a bottom plate  11   a  of the rail  11  is overlapped and the rail  11  is attached. Further, longitudinal directions of the bottom wall  9   a , the inner edge wall  9   b , the second outer edge wall  9   e , the outer edge  9   c  and the rail attaching part  9   d  are parallel to the arrow K. 
     The slit  25  is a gap communicating an inside with an outside of the case  5 , and extended straight in longitudinal directions of the case  5  and the rail  11 , namely, along the arrow K. The slit  25  is a gap for guiding a later-described wire receiving part  15  of the first protector  6  from the inside of the case  5  to the outside of the case  5 , namely, the seat  3 . 
     The second outer edge wall  9   e  is formed in a curved wall gradually approaching the seat  3  as away from the bottom wall  9   a . A surface of the outer edge  9   c  is parallel to a surface of the bottom wall  9   a , and overlapped with a later-described outer edge  10   c  of the upper case  10 . The rail attaching part  9   d  is projected further toward the seat  3  than the other portions of the bottom wall  9   a , and extended straight along longitudinal directions of the rail  11  and the lower case  9 . Further, a surface of the rail attaching part  9   d  is formed flat. 
     Further, as shown in  FIG. 3 , a plurality of through-holes  9   f  penetrating the bottom wall  9   a  and each having a circular shape in a plan view are formed with gaps along the longitudinal direction of the bottom wall  9   a . Later-described cylinder parts  92  of the regulation member  90  are inserted into the through-holes  9   f . Further, in this embodiment, six through-holes  9   f  are formed. One regulation member attaching part  51  is composed of three through-holes  9   f  positioned at the one end  5   a  side of the case  5 . The other regulation member attaching part  52  is composed of three through-holes  9   f  positioned at the other end  5   b  side of the case  5 . 
     The upper case  10  is made of a metal plate, and formed in a rectangular shape in a plan view, of which longitudinal direction is parallel to the arrow K. Namely, a width direction of the upper case  10  is parallel to the width direction H of the vehicle. This upper case  10  includes: a plate-shaped ceiling wall  10   a  arranged parallel to the bottom wall  9   a  with a gap, namely, facing the bottom wall  9   a ; a standing wall  10   e  extended vertically from an edge of the ceiling wall  10   a  positioned at the cabin side; an upper wall  10   b  continued from a top end of the standing wall  10   e  away from the ceiling wall  10   a , and extending in a plate shape toward an inside of the cabin; an outer edge  10   c  disposed outside of the cabin and overlapped with the outer edge  9   c ; and a mall attaching part  10   d  mounted on the upper wall  10   b , overlapped with a later-described mall bracket  8 , and to which the mall bracket is attached. Further, longitudinal directions of the  10   a  ceiling wall  10   a , the standing wall  10   e , the upper wall  10   b , the outer edge  10   c  and the mall attaching part  10   d  are parallel to the arrow K. 
     The ceiling wall  10   a  faces the bottom wall  9   a  at a position where the through-holes  9   f  are formed. The standing wall  10   e  is disposed at substantially the center of the case  5  in the width direction. The top end of the standing wall  10   e  is as high as a top end of the inner edge wall  9   b  of the lower case  9 . The word “high” means a position along a direction T (see  FIG. 6 ) from the floor  2  to the seat  3 . Further, the inner edge  10   f  of the upper wall  10   b  at the inside of the cabin is separated from the inner edge wall  9   b  of the lower case  9  with a gap. The outer edge  10   c  is formed flat, and its planar direction is parallel to a planar direction of the ceiling wall  10   a . The mall attaching part  10   d  is further projected toward the seat  3  than the other parts of the upper wall  10   b , and extended straight along the longitudinal direction of the upper case  10 . Further, a surface of the mall attaching part  10   d  is formed flat. 
     The upper case  10  and the lower case  9  are assembled with each other and compose a tubular case by fixing the outer edge  9   c  and the outer edge  10   c  overlapped with each other with a bolt  12  or the like. Further, as shown in  FIG. 1 , in the case  5 , the bottom wall  9   a  is attached to the floor  2  with a gap by fixing a pair of brackets  65 ,  75  attached to both ends  5   a ,  5   b  in the longitudinal direction of the case  5  with the bolt  12  or the like. Further, while the lower case  9  and the upper case  10  are assembled with each other, the longitudinal directions of the lower case  9 , the upper case  10 , and the rail  11  are parallel to each other, and parallel to the arrow K. 
     Further, the upper case  10  and the lower case  9  are respectively formed by well-known roll forming, extrusion molding, or the like to provide an elongated structure having a constant sectional shape along a sliding direction of the seat  3 , namely, a sliding direction of the first protector  6 , by cutting the elongated structure in a specific length, and by punching a hole for inserting the bolt  12 . Incidentally, the roll forming is a processing method that a band-shaped metal plate sequentially passes through the forming rolls to be deformed along the surface shape of the forming rolls and to be formed in a various shape such as a cylinder shape, a rectangular tubular shape, or the like. 
     Further, in this specification, a space nearer the slit  25  than the rail attaching part  9   d  in an inner space of the case  5  is referred to as a wire moving space  40 , and a space further away from the slit  25  than the rail attaching part  9   d  is referred to as a wire receiving space  41 . The case  5  allows the electric wire  50  to move in linkage with the seat integrally with the first protector  6 . The electric wire  50  covered by the corrugate tube  4  is received in the wire receiving space  41 . 
     The cap  60  is made of synthetic resin, and as shown in  FIG. 6 , includes: an inserting part  61  of which a top end part  61   c  is inserted into an opening  101  disposed at the one end  5   a  of the case  5 , and of which a rear end part  61   b  is positioned at an outside of the opening  101 , namely, an outside of the one end  5   a  along the arrow K; a plate part  64  connected to the rear end part  61   b  of the inserting part  61  via a hinge, and holds the lower case  9  with the top end part  61   c ; and a coupling part  60   c  continued to the inserting part  61 , and attached to an outer edge  9   c  of the lower case  9  by overlapping with a surface of the outer edge  9   c  at the bottom wall  9   a  side. 
     The inserting part  61  includes: an upper wall  61   a ; and a bottom wall  61   d  facing the upper wall  61   a , and positioned on the floor  2  to abut on the floor  2  while the case  5  is fixed to the floor  2 . A portion of the upper wall  61   a  abutting on an inner surface of the ceiling wall  10   a  of the upper case  10  at the bottom wall  9   a  side while the top end part  61   c  is inserted into the opening  101  is referred to as a “ceiling wall abutting part  164 ”. Further, a portion of the upper wall  61   a  positioned at the outside of the opening  101 , and overlapped with the bracket  65  while the top end part  61   c  is inserted into the opening  101  is referred to as “a bracket abutting part  165 ”. 
     Further, a groove  62  concaved to the bottom wall  61   d  side, namely, the floor  2  side from the upper wall  61   a  and extended from the top end part  61   c  to the rear end part  61   b  is formed on the inserting part  61  of the cap  60 . The corrugate tube  4  receiving the electric wire  50  is positioned to an inside of this groove  62 , and the corrugate tube  4 , namely, the electric wire  50  received in the case  5  is guided out to an outside of the case  5  via the groove  62 . Further, the electric wire  50  guided out to an outside of the case is connected to the electronic device such as ECU attached to the floor  2  side. 
     The plate part  64  includes a pair of rocking claws  64   a ,  64   b  extending vertically from an edge at the top end part  61   c  side toward the upper wall  61   a . These rocking claws are arranged with a gap in a width direction H perpendicular to the arrow K. These rocking claws are respectively engaged with a pair of rocking receivers  60   a ,  60   b  disposed at the top end part  61   c  with a gap while the rocking claws are inserted into a pair of attaching holes  9   g  (only one hole is shown in  FIG. 6 ) disposed on the bottom wall  9   a  of the lower case  9  with a gap. Further, the plate part  64  abuts on the floor  2  by positioning a bottom wall  64   c  disposed at a side away from the upper wall  61   a  on the floor  2  while the case  5  is fixed to the floor  2 . 
     The coupling part  60   c  includes an enclosure part  60   d  formed in a rectangular tubular shape and having an upper wall  160  overlapped with the outer edge  9   c  of the lower case  9 , a pair of plate parts  161  arranged in the width direction H from the upper wall  160  with a gap and projected in a plate shape, and a connecting part  162  connecting ends of the pair of plate parts  161  away from the upper wall  160  side together. When the cap  60  is attached to the one end  5   a , an attaching piece  109  of the lower case  9  is received in an inside of the enclosure part  60   d , and an inner surface of the enclosure part  60   d  closely contacts an outer surface of the attaching piece  109 , thereby the enclosure part  60   d  is attached to the outer edge  9   c . The attaching piece  109  is a portion extended in a plate shape to the outside of the lower case  9  along the arrow K from an end  9   j  (indicated by two-dot chain line in  FIG. 6 ) of the outer edge  9   c  along the arrow K. Further, the enclosure part  60   d  attached to the outer edge  9   c  is positioned in a notch part  110  of the outer edge  10   c  of the upper case  10 . The notch part  110  is a partially notched portion of the outer edge  10   c  extending from an edge part  10   j  of the outer edge  10   c  positioned at an outside of the cabin toward the inner edge  10   f . Further, the coupling part  60   c  abuts on the floor  2  by positioning a bottom wall  163  disposed away from the upper wall  160  on the floor  2  while the case  5  is fixed to the floor  2 . 
     The above-described bottom wall  61   d , the bottom wall  64   c , and the bottom wall  163  are the “vehicle body abutting part” in claims. 
     The cap  70  is made of synthetic resin, and has the same structure as the above-described cap  60  except that the groove  62  is not formed. The caps  60 ,  70  prevent a foreign particle from entering the case  5 , and prevent the electric wire  50  from falling out of the case  5  by attaching to the ends  5   a ,  5   b  of the case  5 . 
     The pair of brackets  65 ,  75  is made by pressing a metal plate, and respectively includes: one ends  66 ,  76  attached to an inner surface of the ceiling wall  10   a  of the upper case  10  at the bottom wall  9   a  side by welding or the like; the other ends  68 ,  78  attached to the floor  2 ; and middle parts  67 ,  77  interposed between the one ends  66 ,  76  and the other ends  68 ,  78 . The other ends  68 ,  78  include flat parts to be overlapped with the surface of the floor  2 , and have holes  68   a ,  78   a  for inserting the bolts  12 . Further, the middle parts  67 ,  77  are overlapped with the bracket abutting parts  165  of the caps  60 ,  70 . Therefore, when the load is applied to the brackets  65 ,  75 , the bracket abutting parts  165  support the brackets  65 ,  75  to prevent the brackets  65 ,  75  from being deformed. Incidentally, the brackets  65 ,  75  are shown in  FIG. 3 , however, in reality, the one ends  66 ,  76  are previously attached to the upper case  10 . 
     As shown in  FIG. 3 , the regulation member  90  is extended from the one end  5   a  of the case  5  to the center in the longitudinal direction of the case  5 . This regulation member  90  is made of synthetic resin or the like, and formed independently from the case  5 . Further, the regulation member  90  includes: a rectangular cylinder part  91  of which longitudinal direction is parallel to the arrow K; a plurality of circular cylinder parts  92  projected from a bottom wall  91   a  of the rectangular cylinder part  91 ; and a plurality of wire fixing parts  93  disposed at a side wall  91   b  of the rectangular cylinder part  91 , and fixing the corrugate tube  4  by wrapping around an outer periphery of the corrugate tube  4 . Further, in this embodiment, three circular cylinder parts  92  are provided, and two wire fixing parts  93  are provided. A height of the rectangular cylinder  91  is the same as a distance between the bottom wall  9   a  and the upper wall  10   b  of the case  5 . Incidentally, the “height” means a size from the bottom wall  91   a  from which the circular cylinder part  92  is projected to the upper wall  91   c  facing the bottom wall  91   a . The circular cylinder parts  92  are arranged in a longitudinal direction of the rectangular cylinder part  91  with gaps between them. A diameter of each circular cylinder part  92  is slightly smaller than that of the through-hole  9   f . Further, the regulation member  90  is formed in a plane-symmetrical shape relative to a virtual plane passing the center of the regulation member  90  and perpendicular to the arrow K direction. 
     As shown in  FIGS. 4 and 5 , while the bottom wall  91   a  of the rectangular cylinder part  91  abuts on the bottom wall  9   a  of the lower case  9 , and each circular cylinder part  92  is projected to an outside of the case  5  via the through-holes  9   f  of the regulation member attaching part  51 , the regulation member  90  is fixed to the lower case  9  with the bolt  12  or the like, and interposed between the bottom wall  9   a  of the lower case  9  and the ceiling wall  10   a  of the upper case  10 . Thus, in a condition that the regulation member  90  is attached to the case  5 , and the case  5  is attached to the floor  2 , the upper wall  91   c  of the rectangular cylinder part  91  abuts on the ceiling wall  10   a , the bottom wall  91   a  of the rectangular cylinder part  91  abuts on the bottom wall  9   a , the circular cylinder part  92  is projected out of the case  5  via the through-hole  9   f , and a lower wall  92   a  of the circular cylinder part  92  abuts on the floor  2 . 
     The regulation member  90  partitions the wire receiving space  41  into a first space  46  near the wire moving space  40 , and a second space  47  away from the wire moving space  40 . These first and second spaces  46 ,  47  are connected to each other at the other end  5   b  of the case  5 . The corrugate tube  4  and a part of the electric wire  50  near the floor  2  side are received in the second space  47 . The corrugate tube guided from the second space  47  via the other end  5   n  of the case  5 , and a part of the electric wire  50  near the seat  3  are received in the first space  46 . Namely, the regulation member  90  regulates the cabling route of the electric wire  50  in the case  5  in a U-shape by partitioning the case  5 . 
     The rail  11  is made of a metal plate, and formed independently from the lower case  9 . As shown in  FIG. 4 , the rail  11  is formed in a rectangular shape in a plan view of which longitudinal direction is parallel to the arrow K. Further, the rail  11  includes: a plate-shaped bottom plate part  11   a ; and a pair of hook walls  11   b  vertically extending from both edge in a width direction (perpendicular to the arrow K) of the bottom plate part  11   a . The bottom plate part  11   a  is overlapped with a flat surface of the rail attaching part  9   d , and fixed to the rail attaching part  9   d  by welding or the like. The pair of hook walls  11   b  is extended straight parallel to each other from both edges in the width direction of the bottom plate part  11   a , then, extended in a direction approaching each other parallel to the bottom plate part  11   a , thereby a cross section of the hook wall  11   b  is formed in a hook shape. 
     As shown in  FIG. 4 , the rail  11  is shifted from the slit  25  in a width direction of the rail  11 . Further, the rail  11  and the rail attaching part  9   d  partition the inner space of the case  5  into the wire moving space  40  near the slit  25  and the wire receiving space  41  away from the slit  25 . Further, a gap D between the rail  11  and an inner surface of the upper wall  10   b  of the upper case  10  is narrower than an outer diameter R of the corrugate tube  4 . 
     Each of the mall brackets  8  is formed in a flat plate shape. These mall brackets  8  are arranged along the longitudinal direction of the mall attaching part  10   d  with gaps between them, and attached to a surface of the mall attaching part  10   d . Further, a width of the mall bracket  8  perpendicular to the arrow K is wider than a width of the mall attaching part  10   d , and both ends of the mall bracket  8  are disposed outside of both ends of the mall attaching part  10   d . A later-described fixing part  20  of the mall  7   a  is attached to such a mall bracket  8 . 
     The pair of malls  7   a ,  7   b  is made of synthetic resin, formed in a plate shape, and attached to the case  5  in a manner that longitudinal directions of the malls  7   a ,  7   b  are parallel to the arrow K. Further, the pair of malls  7   a ,  7   b  is arranged with a gap which is parallel to the surface of the floor  2  and perpendicular to the arrow K, and the slit  25  is positioned between the pair of malls  7   a ,  7   b . A later-described wire receiving part  15  of the first protector  6  is inserted into the slit  25 . Namely, the wire receiving part  15  is positioned between the pair of malls  7   a ,  7   b.    
     Further, as shown in  FIG. 4 , the pair of malls  7   a ,  7   b  integrally includes: a flat-plate-shaped main body part  16  overlapped with the case  5 ; and an elastically deformable abutting piece  17  extending from the main body part  16  and abutting on the wire receiving part  15  of the first protector  6 . The abutting pieces  17  of the pair of malls  7   a ,  7   b  cover a space between the inner edge  10   f  of the upper case  10  and the inner edge wall  9   b  of the lower case  9 , namely, the slit  25  to prevent a foreign particle or the like from entering the space. 
     One mall  7   a  positioned at an outside of the cabin further includes the fixing part  20  to be attached to the mall bracket  8 . This fixing part  20  includes: a pair of standing parts  26  standing from the main body part  16 ; and a pair of extending parts  27  extending from both edges of the standing parts  26  away from the main body part  16  in a direction approaching each other. 
     The pair of standing parts  26  is arranged along a width direction (perpendicular to the arrow k) of the mall bracket  8  with a gap between them, and extending from the main body part  16  toward the upper case  10  parallel to each other. The mall attaching part  10   d  and the mall bracket  8  are positioned between the pair of standing parts  26 . The pair of extending parts  27  is extended from the above-described edges of the standing parts  26  along a surface of the upper wall  10   b  of the upper case  10 . Further, the standing parts  26  and the extending parts  27  are extended straight along the arrow K. 
     As shown by a chain line in  FIG. 2 , when the mall  7   a  is slid on the upper case  10  along the arrow K, the extending parts  27  are positioned between the both ends of the mall bracket  8  and the upper case  10 , and the both ends of the mall bracket  8  is positioned between the extending parts  27  and the main body part  16  sequentially from the mall bracket  8  positioned at one end of the arrow K of the upper case  10  to the mall bracket  8  positioned at the other end. Thus, the mall  7   a  is attached to the upper case  10 , namely, the case  5 . Further, the other mall  7   b  is attached to the inner edge wall  9   b  of the lower case  9  with a double-sided adhesive tape or the like. 
     The first protector  6  is made of synthetic resin, and as shown in  FIGS. 1 and 4 , includes: a sliding part  13 , a tube fixing part  14 , and a wire receiving part  15 . The sliding part  13  is projected downward from the wire receiving part  15 , received in the rail  11 , and slidably supported in the longitudinal direction of the rail  11  by the rail  11 . Namely, the first protector  6  is slidably provided along the longitudinal direction of the rail  11 . The tube fixing part  14  fixes an end of the corrugate tube  4 . The wire receiving part  15  is formed in a tubular shape, and one end of the wire receiving part  15  is continued to the tube fixing part  14 . When the sliding part  13  is slidably supported by the rail  11 , the other end of the wire receiving part  15  is projected toward the seat  3  from the case  5  via the slit  25 . The electric wire  50  guided out from the end of the corrugate tube  4  is inserted into the wire receiving part  15 , and guided from the case  5  to the seat  3 . Further, a wire fixing part  15   a  for fixing the electric wire  50  is provided on the wire receiving part  15 . 
     The second protector  30  is made of synthetic resin, and as shown in  FIGS. 1 and 4 , includes: a second wire receiving part  31  of which inside the electric wire  50  guided out from the wire receiving part  15  is positioned at; and a flange part  32  attached to the seat  3 . A wire fixing part  31   a  for fixing the electric wire  50  is provided on the second wire receiving part  31 . 
     A string  19  is tied between the first protector  6  and the flange part  32  of the second protector  30 . Therefore, the first protector  6  is movably provided along the longitudinal direction of the rail  11 , namely, the arrow K, and by pulling by the second protector  30 , namely, the seat  3  with the string  19 , the first protector  6  is movably provided in linkage with the seat  3  along the arrow K. 
     Further, an end of a mat  28  put on the floor  2  is pressed into between the mall  7   a  of the wire cabling device  1  and the upper case  10 , namely, the case  5 . Then, the end of the mat  28  is fixed to at least one of the mall  7   a  and the upper case  10 . 
     As shown in  FIG. 7 , the wire cabling device  1  is attached to the floor  2 , and provides the electric wire  50  to the seat  3  of an assistant driver side. Further, in a wire cabling device  1 ′ providing the electric wire  50  to the seat  3  of a driver side, the case  5  and the regulation member  90  are designed in a line-symmetric shape along a width direction H of a vehicle with the wire cabling device  1 . Namely, the case  5  of the wire cabling device  1 ′ is the case  5  of the wire cabling device  1  rotated 180 degree in which the regulation member  90  is previously attached to the regulation member attaching part  52  of the case  5  of the wire cabling device  1  in  FIG. 7 . Thus, in the present invention, the case  5  of the wire cabling device  1  and the case  5  of the wire cabling device  1 ′ are commonly used. Further, the regulation member  90 , the corrugate tube  4 , the pair of malls  7   a ,  7   b , and the rail  11  are also commonly used. 
     When the wire cabling device  1  and the wire cabling device  1 ′ are produced, firstly, the upper case  10  and the lower case  9  are produced by well-known roll forming, extrusion molding, or the like to provide an elongated structure having a constant sectional shape along a sliding direction of the seat  3 , namely, a sliding direction of the first protector  6 , by cutting the elongated structure in a specific length, and by punching holes for inserting the bolts  12  and punching six through-holes  9   f . Then, the regulation member  90  produced independently from the case  5  is attached to either of the two regulation member attaching parts  51 ,  52  corresponding to whether a left side or a right side of a vehicle. Then, the other parts are attached to the lower case  9  corresponding to whether the left side or the light side of the vehicle, the upper case  10  is overlapped with the lower case  9 , and fixed to the lower case  9  with the bolts  12 , thereby the wire cabling device  1  and the wire cabling device  1 ′ are produced. 
     In the present invention, because the regulation member  90  is formed independently from the case  5 , the shape of the case  5  can be a tubular shape having a constant sectional shape along the sliding direction of the seat  3 . Therefore, in a plurality of wire cabling devices  1 ,  1 ′ respectively cabling electric wires to a plurality of seats  3  provided on the right and left sides of a vehicle, the case  5  can be commonly used. Further, these cases  5  can be made by roll forming or extrusion molding having high productivity. Resultingly, a cost of the wire cabling device  1 ,  1 ′ can be reduced, and a production cost of the case  5  can be reduced. 
     Further, in the present invention, because regulation member attaching parts  51 ,  52  are provided on two places, one end  5   a  and the other end  5   b  of the case  5 , in a plurality of wire cabling devices  1 ,  1 ′, it is unnecessary to respectively provide the regulation member attaching parts  51 ,  52  to the cases  5  independently. Therefore, the production cost of the case  5  can be reduced. 
     Further, in the present invention, because the regulation member  90  is formed in a plane-symmetrical shape relative to a virtual plane passing the center of the regulation member  90  and perpendicular to the sliding direction of the seat  3 , in a plurality of wire cabling devices  1 ,  1 ′, not only the case  5  but also the regulation member  90  can be commonly used. Therefore, the cost of the wire cabling device  1 ,  1 ′ can be further reduced. 
     Further, the wire cabling device  1 ,  1 ′ is provided under the seat  3 , and hidden under the mat  28  (see  FIG. 4 ). Therefore, a crew member may stamp the wire cabling device  1 ,  1 ′ in an arrow F direction of  FIG. 4 . 
     At this point, in the present invention, when a load is applied from the ceiling wall  10   a  toward the bottom wall  9   a  along the arrow F, the caps  60 ,  60 ′  70 ,  70 ′ and the regulation member  90  work as supports and the load is not applied to the bottom wall  9   a , and transmitted to the floor  2 , thereby the stress generated in the case  5  is reduced. Therefore, the rigidity capable of sufficiently enduring the load can be attained using the case  5  and the pair of caps  60 ,  60 ′,  70 ,  70 ′ made by a process having high productivity such as roll forming or extrusion molding without providing a bead shape (namely, convexes and concaves made by press working) for increasing the rigidity which is provided in a conventional case by press working. Further, because a thickness of the case  5  can be reduced, the case  5  can be lighter, and a material cost can be reduced. Further, because the number of bolting positions for preventing the case  5  from being deformed by the load can be further reduced than the conventional case, design flexibility of the case  5  is increased, and man-hours for bolting the case  5  can be reduced. 
     Further, when convexes and concaves of which shapes depend on a car type are formed on a surface of the floor  2  to which the case  5  is attached, because the case  5  is disposed with a gap from the floor  2 , it is unnecessary to design the bottom wall  9   a  of the case  5  in order to fit the convexes and the concaves, and only the bottom walls  61   d ,  64   c ,  163  of the cap  60 ,  60 ′,  70 ,  70 ′ are designed in order to fit the concaves and the convexes. Therefore, the case  5  can be commonly used in different car types. 
     Further, in the above-described embodiment, the case  5  is composed of two members, the lower case  9  and the upper case  10 . However, in the present invention, the case  5  may be composed of one member. 
     Although the present invention has been fully described by way of example with reference to the accompanying drawings, it is to be understood that various changes and modifications will be apparent to those skilled in the art. Therefore, unless otherwise such changes and modifications depart from the scope of the present invention hereinafter defined, they should be construed as being included therein.
