     DETAILED DESCRIPTION TO EXECUTE THE INVENTION 
     Description of Embodiment of Disclosure 
     First, embodiments of the present disclosure will be listed and described. 
     A wiring module according to the present disclosure is as follows. 
     (1) A wiring module including a base member including an attachment surface on which an attachment target portion is formed, a plurality of wiring members arranged on the attachment surface, and a holding member attached to the attachment target portion while holding the plurality of wiring members, wherein the holding member includes a holding portion formed by a plurality of grooves arranged side by side, and an attachment portion configured to be detachably attached to the attachment target portion, the attachment target portion is provided at each of a plurality of attachment locations along paths of the plurality of wiring members on the attachment surface, and at each of the plurality of attachment locations, the plurality of wiring members are divided, housed and held in the plurality of grooves. Since the holding member is detachably attached to the base member, when the wiring members need to be repaired, the wiring members can be detached from the base member together with the holding member. Even if the wiring members are detached from the base member together with the holding member, the base member does not need to be replaced or repaired. In this manner, repairability can be improved in the wiring module in which the wiring members are housed in the grooves. 
     (2) A configuration is also possible in which in a state where at least the holding member is not attached to the base member, the holding portion is elastically deformable such that openings of the grooves that are on the opposite side to bottoms of the grooves widen. In this manner, since the wiring members are detachably held in the grooves, when a portion of the plurality of wiring members needs to be repaired, even if that portion of the wiring members is detached from the holding member, the holding member does not need to be replaced or repaired. In this manner, repairability in the wiring module can be improved. 
     (3) A configuration is also possible in which in a state where the holding member is not attached to the base member, the holding portion is elastically deformable so as to bend around an axis parallel with an extension direction of the grooves, the openings of the grooves that are on the opposite side to the bottoms of the grooves widen in a state where the holding portion bends in one direction around the axis, and the attachment portion is attached to the attachment target portion in a manner capable of inhibiting the holding portion from bending in the one direction around the axis. In this manner, when the wiring members need to be removed from and attached to the grooves, by the holding portion being removed and attached in a bent state, the wiring members can be easily removed and attached. Also, in the wiring module in the state where the holding portion is attached to the base member, removal and attachment of the wiring members from and to the grooves can be inhibited. 
     (4) A configuration is also possible in which protrusions that narrow a width dimension of the grooves are formed at the openings of the grooves that are on the opposite side to the bottoms of the grooves. In this manner, due to the protrusions, the wiring members housed in the grooves can be inhibited from coming out of the grooves. Further, even if the protrusions are provided, when the wiring members need to be removed from and attached to the grooves, such removal and attachment can be easily performed by the opening portions being widened due to elastic deformation of the holding portion. 
     (5) A configuration is also possible in which the holding member further includes a first linking portion provided on one side of the holding portion and a second linking portion provided on the other side of the holding portion, and in at least one attachment locations of the plurality of attachment locations, the first linking portion of one holding member and the linking portion of another holding member link to each other. In this manner, a single kind of holding member can easily support various modes of wiring members. 
     (6) A configuration is also possible in which the holding member further includes a lid portion for covering the plurality of grooves. In this manner, due to the lid portion, the linear transmission members can be inhibited from coming out of the grooves. 
     (7) A configuration is also possible in which the attachment portion and the attachment target portion are provided at two sides of the holding portion, and the attachment portion is detachably attached to the attachment target portion by a protrusion formed at one of the attachment portion and the attachment target portion fitting in a recess formed at the other of the attachment portion and the attachment target portion. In this manner, the holding member can be attached to and detached from the base member in a simple manner. 
     (8) A configuration is also possible in which a fitting groove to which the holding portion fits is formed in the attachment surface. In this manner, an increase in height of the wiring module in the normal direction of the attachment surface can be suppressed. 
     (9) A wiring member with holding member according to the present disclosure includes a plurality of wiring members, and a plurality of holding members divided and provided in a plurality of attachment locations arranged at intervals along an extension direction of the plurality of wiring members, wherein each of the plurality of holding members includes a holding portion formed by a plurality of grooves arranged side by side, and an attachment portion that is configured to be detachably attached to an attachment partner, and at each of the plurality of attachment locations, the plurality of wiring members are divided, housed and held in the plurality of grooves. The plurality of holding members are provided separately at the plurality of attachment locations at intervals along the extension direction of the plurality of wiring members, and at each of the attachment locations, the plurality of wiring members are separately housed and held in the plurality of grooves in a state of being arranged side by side. Then, due to the attachment portion provided at the holding member, the wiring members with holding member can be detachably attached to the attachment partner. In this manner, repairability can be improved.

The two holding members  50  are linked by the linking protrusion  58  of one holding member  50  fitting into the linking recess  60  of the other holding member  50 . 
     Since the linking protrusion  58  laterally protrudes from the first protrusion  55 , in the attachment target portions  34 , the first recess  36  to which the first protrusion  55  fits is formed in a shape obtained by combining the first protrusion  55  and the linking protrusion  58 . The linking recess  60  is formed such that a portion of the second protrusion  56  is recessed. For this reason, even if the second recess  38  is formed in a shape that conforms to the second protrusion  56 , the second protrusion  56  can fit to the second recess  38 . A protrusion to fit to the linking recess  60  may be formed in the second recess  38 . 
     The link between the two linked holding members  50  can be released in a state of being removed from the base member  30 . Here, the direction in which the two holding members  50  link to each other and the direction in which the holding member  50  is attached to the base member  30  are the same. For this reason, the link between the two linked holding members  50  can be released in a state of being attached to the base member  30  as well. 
     The holding member  50  including the first linking portion  57  and the second linking portion  59  is formed in a shape that is rotationally asymmetrical with respect to an axis along the normal direction of the bottom plate  51   a . In this manner, the holding member  50  is unlikely to be attached to the base member  30  in a wrong orientation. Note that the holding member  50  including the first linking portion  57  and the second linking portion  59  may be formed in a shape that is rotationally symmetrical with respect to the axis along the normal direction of the bottom plate  51   a . For example, due to the first linking portion  57  and the second linking portion  59  each including a pair of a protrusion and a recess, they are formed in a shape that is rotationally symmetrical with respect to the axis along the normal direction of the bottom plate  51   a . In this manner, no matter which of leftward or rightward is the orientation in which the holding member  50  is attached to the wiring members  40 , the holding member  50  can be attached to the base member  30 . In this manner, the orientation of the holding member  50  does not need to be considered when attaching the holding member  50  to the wiring members  40 . 
     Note that, in the case where the first linking portion  57  and the second linking portion  59  are omitted, the holding member  50  is formed in a shape that is rotationally symmetrical with respect to the axis along the normal direction of the bottom plate  51   a.    
     In a state where at least the holding member  50  is not attached to the base member  30 , the holding portion  51  can elastically deform such that the openings of the grooves  52  on the opposite side to the bottoms thereof are widened. For example, due to a partition  51   b  between the adjacent grooves  52  inclining toward the one groove  52 , the opening of the other groove  52  can be widened. 
     Here, in the state where the holding member  50  is not attached to the base member  30 , the holding portion  51  can elastically deform so as to bend around an axis parallel to the extension direction of the grooves  52 . In a state where the holding portion  51  is bent in one axial direction, the openings of the grooves  52  on the opposite side to the bottoms thereof are widened. Here, as shown in  FIG.  5   , the bottom plate  51   a  can be elastically deformed so as to be bent around the axis. In the state where the bottom plate  51   a  is bent in the one axial direction, the partitions  51   b  facing each other extend in the direction of separating from each other proceeding from the base end portions on the bottom plate  51   a  side toward the leading end portions thereof. In the partitions  51   b  facing each other, gaps at the leading end portions are larger than the gaps at the base end portions. In this manner, the openings of the grooves  52  are widened. 
     The holding members  50  are formed by an elastically deformable material such that the bottom plate  51  can bend around the axis. For example, the material for the holding members  50  may also be an elastomer such as rubber. For example, the material for the holding members  50  may also be a thermoplastic elastomer such as olefin-based elastomer. 
     The attachment portions  54  are attached to the attachment target portions  34  such that bending of the holding portion  51  in one axial direction can be suppressed in the state where the holding member  50  is attached to the base member  30 . Here, the attachment portions  54  and the attachment target portions  34  are attached to the two sides of the holding portion  51 . In this manner, bending of the holding portion  51  in one axial direction can be suppressed in the state where the holding member  50  is attached to the base member  30 . Further, the bottom plate  51   a  is in surface contact with the attachment surface  33 . In this manner as well, bending of the holding portion  51  to one axial direction can be suppressed in the state where the holding member  50  is attached to the base member  30 . 
     For example, a configuration is also possible in which the first protrusion  55  and the second protrusion  56  of the attachment portion  54  are formed slightly larger than the first recess  36  and the second recess  38  of the attachment target portions  34 , and the first protrusion  55  and the second protrusion  56  are pressed into the first recess  36  and the second recess  38 . If the material for the holding member  50  is an elastomer, when the first protrusion  55  and the second protrusion  56  are pressed into the first recess  36  and the second recess  38 , the holding member  50  is unlikely to come out of the base member  30 . 
     The holding portion  51  may also be elastically deformable such that the openings of the grooves  52  are widened in the state where the holding member  50  is attached to the base member  30 . For example, due to the partition  51   b  between the adjacent grooves  52  being inclined toward one groove  52 , the opening of the other groove  52  can be widened. In this case, it is preferable that an elastic force is set such that the wiring members  40  will not come out of the grooves  52  due to a force that is applied when the vehicle is in normal use (e.g., vibration at the time of opening/closing the door  10 ). The threshold at which the wiring members  40  come out of the grooves  52  is greater than or equal to a force that is applied when the vehicle is in normal use. When a force greater than the threshold is applied, the wiring members  40  come out of the grooves  52 . The holding portion  51  may not be elastically deformable such that the openings of the grooves  52  are widened in the state where the holding member  50  is attached to the base member  30 . 
     Also, as shown in  FIG.  2   , the wiring members  40  with the holding member  50  provided at predetermined locations are referred to as “wiring members  40  with holding member  50 ”. The holding member  50  of these wiring members  40  with holding member  50  is attached to the attachment target portions  34 , and thus the wiring module  20  is formed. 
     Effects and the Like of First Embodiment 
     According to the wiring module  20  and the wiring members  40  with holding member  50  configured as above, since the holding member  50  is attachable to/detachable from the base member  30 , when the wiring members  40  need to be repaired, the wiring members  40  can be detached from the base member  30  together with the holding member  50 . Even if the wiring members  40  are detached from the base member  30  together with the holding member  50 , the base member  30  does not need to be replaced or repaired. In this manner, according to the wiring module  20  in which the wiring members  40  are housed in the grooves  52 , repairability can be improved. Note that, a configuration is also possible in which the wiring members  40  can be detached from the base member  30  together with the holding member  50  while the base member  30  remains attached to the vehicle. 
     Further, in a state where at least the holding member  50  is not attached to the base member  30 , the holding portion  51  can elastically deform such that the openings of the grooves  52  on the opposite side to the bottoms thereof are widened. In this manner, since the wiring members  40  are detachably held in the grooves  52 , when a portion of the plurality of wiring members  40  needs to be repaired, even if that portion of the wiring members  40  is detached from the holding member  50 , the holding member  50  does not need to be replaced or repaired. In this manner, repairability in the wiring module  20  can be improved. 
     Further, in a state where the holding member  50  is not attached to the base member  30 , the openings of the grooves  52  on the opposite side to the bottoms thereof are widened with the holding portion  51  bending in one axial direction. Further, the attachment portions  54  are attached to the attachment target portions  34  such that the holding portion  51  can be inhibited from bending in the one axial direction. In this manner, when the wiring members  40  need to be removed from and attached to the grooves  52 , by the holding portion  51  being removed from and attached to the grooves  52  in a bent state, the wiring members  40  can be easily removed from and attached to the grooves  52 . Further, in the wiring module  20 , the wiring members  40  can be inhibited from being detached from and attached to the grooves  52 . 
     Further, the protrusions  53  that narrow the width dimension of the grooves  52  are formed at the openings of the grooves  52 . In this manner, due to the protrusions  53 , the wiring members  40  housed in the grooves  52  can be inhibited from coming out of the grooves  52 . Also, even if the protrusions  53  are formed, when the wiring members  40  need to be removed from and attached to the grooves  52 , the wiring members  40  can be easily removed from and attached to the grooves  52  due to elastic deformation of the holding portion  51 . 
     Further, in at least one attachment location out of the plurality of attachment locations, the first linking portion  57  of the one holding member  50  is linked to the second linking portion  59  of another holding member  50 . In this manner, a single kind of holding member  50  can support various types of the wiring members  40 . 
     Further, the attachment portions  54  and the attachment target portions  34  are provided on the two sides of the holding portion  51 , and the protrusion formed at one of the attachment portions  54  and the attachment target portions  34  fits to the recess formed in the other, making it possible for the attachment portions  54  to be detachably attached to the attachment target portions  34 . In this manner, the holding member  50  can be easily attached to and detached from the base member  30 . 
     Further, the grooves  52  to which the holding portion  51  fits are formed in the attachment surface  33 . In this manner, an increase in height of the wiring module  20  along the normal direction of the attachment surface  33  can be suppressed. 
     Variation 
       FIG.  6    is a perspective view showing a variation of the holding member  50 .  FIG.  7    is a front view showing the variation of the holding member  50 . 
     A holding member  150  according to the variation is different from the holding member  50  in that a lid portion  62  is further included. The lid portion  62  covers the plurality of grooves  52 . In this manner, due to the lid portion  62 , the wiring members  40  can be inhibited from coming out of the grooves  52 . 
     In the example shown in  FIG.  6   , the lid portion  62  is integrally molded with the holding portion  51  and the attachment portions  54 . The lid portion  62  is provided at one attachment portion  54  via a hinge  63 . Locking portions  64  are provided at the lid portion  62 . Locking target portions  65  are provided at the other attachment portion  54 . In the state where the lid portion  62  is closed, the locking portions  64  lock to the locking target portions  65 . In this manner, the lid portion  62  is kept in a closed state. 
     The lid portion  62  may also be molded separately from the holding portion  51  and the attachment portion  54 . For example, the locking portions  64  may be provided at the two sides of the lid portion  62 , and the locking target portions  65  may be provided at the two attachment portions  54 . 
     In addition, in the above description, the base member  30  is a member embedded between the door panel  12  and the door trim  16 . However, such a configuration is not essential. For example, the base member  30  may also be a member embedded between a roof panel and a roof lining, or a member embedded between exterior members that constitute the outer appearance of the vehicle and interior members that constitute the inner appearance of the vehicle. Also, for example, the base member  30  may also be an interior member such as a door trim  16 , a roof lining, an instrument panel, or the like. 
     Also, the holding portion  51  may also be formed such that the openings of the grooves  52  are not elastically deformable so as to be widened. Also, the holding portion  51  may also be formed such that the bottom plate  51   a  is not elastically deformable so as to bend axially. The protrusions  53  do not need to be formed at the openings of the grooves  52 . 
     Further, the attachment portions  54  and the attachment target portions  34  may also have a structure other than the protrusions fitting into the recesses. For example, the attachment portions  54  and the attachment target portions  34  may also have a locking structure such as the locking portions  64  and the locking target portions  65 . 
     Also, the attachment direction of the attachment portions  54  and the attachment target portions  34  may also be different from the linking direction of the first linking portions  57  and the second linking portions  59 . In this case, the link between the two linked holding members  50  cannot be released in the state where the holding members  50  are attached to the base member  30 . For example, one of the attachment direction and the linking direction may be parallel with the normal direction of the attachment surface  33 , and the other may be a direction orthogonal to the normal direction (direction along the attachment surface  33 ). The direction orthogonal to the normal direction may be parallel with the direction in which the plurality of grooves  52  are arranged side by side, or the direction parallel with the direction in which the grooves  52  extend. 
     The first linking portion  57  and the second linking portion  59  can also be used as the attachment portions  54 . For example, a configuration is also possible in which, in the holding member  50 , the attachment portions  54  are omitted, and a recess to which the first linking portion  57  fits and a protrusion that fits to the second linking portion  59  may be formed as the attachment target portions  34  of the base member  30 . 
     Further, the first linking portions  57  and the second linking portions  59  may also be omitted from the holding members  50 . The holding members  50  may not be capable of linking to each other. In this case, at the attachment location APS, a holding member  50  having a holding portion  51  that is longer than the holding portion  51  of the holding member  50  of the attachment location AP 1  may be attached. Further, at the attachment location APS, two holding members  50  that are the same as the holding member  50  at the attachment location AP 1  may also be separately attached. 
     Further, in the wiring module  20 , the holding members  50  may be attached with the openings of the grooves  52  facing the attachment surface  33 . In this case, the attachment surface  33  functions as a lid for the openings of the grooves  52 , making it possible to inhibit the wiring members  40  from coming out of the grooves  52 . 
     Further, in the wiring module  20 , the two holding members  50  may be linked such that the openings of the grooves  52  face each other. In this case, one holding member  50  functions as a lid for the openings of the grooves  52  of the other holding member  50 , making it possible to inhibit the wiring members  40  from coming out of the grooves  52 . The holding members  50  may also have a linking portion that makes it possible for two holding members  50  to link to each other in the height direction. 
     Note that, the constituent elements described in the above embodiments and variations may be combined as appropriate as long as no mutual contradictions arise.
