{First embodiment}
Hereinafter, the wire mounting structure 20 and the wire module 10 according to the first embodiment will be described. FIG. 1 is a front view showing an electric wire module 10 according to the first embodiment. FIG. 2 is a front view showing the fixing portion 30 of the wire mounting structure 20 according to the first embodiment. FIG. 3 is a side view showing the fixing portion 30 of the electric wire attachment structure 20 according to the first embodiment. FIG. 4 is a plan view showing the main body 50 of the wire mounting structure 20 according to the first embodiment. FIG. 5 is a front view showing the main body 50 of the electric wire mounting structure 20 according to the first embodiment.

  The electric wire module 10 according to the first embodiment includes an electric wire 12 and an electric wire mounting structure 20.

  At least one electric wire 12 is included. Here, a wire bundle in which a plurality of wires 12 are bundled is used as the wire 12. Moreover, the electric wire 12 is used as a wiring material which is wired by the vehicle etc. and electrically connects various electric components. The electric wire 12 may include an optical fiber cable or the like. In the electric wire 12 of FIG. 1, an outline of an electric wire bundle in which a plurality of electric wires 12 are bundled is drawn.

  The electric wire attachment structure 20 is a member for fixing the electric wire 12 to the attachment object 80. The electric wire attachment structure 20 includes a fixing portion 30 fixed to an attachment hole 82 formed in the attachment object 80, and a main body portion 50 formed separately from the fixing portion 30.

  Here, the fixing portion 30 will be described as being fixed to an attachment hole 82 formed in the vehicle body panel 80. The fixing portion 30 can be inserted into the mounting hole 82 of the vehicle body panel 80 to which the electric wire 12 is fixed, and is formed in a shape that can be locked to the mounting hole 82 after being inserted into the mounting hole 82 and can be removed. Has been. Specifically, the fixing portion 30 includes a shaft portion 32, an attachment piece 34, and a fitting portion 40.

  The shaft portion 32 is formed in a rod shape. The shaft portion 32 is provided so as to connect the attachment piece 34 and the fitting portion 40.

  The attachment piece 34 is provided on one end side of the shaft portion 32. The attachment piece 34 is formed in a shape extending obliquely so as to spread from both sides on one end side of the shaft portion 32 toward the other end portion side of the shaft portion 32. On the distal end side of the mounting piece 34, a portion of the mounting piece 34 that has the largest protrusion amount in the direction perpendicular to the shaft portion 32 (the most protruding portion 35) is provided. An outer dimension of the most protruding portion 35 is formed to be larger than a diameter of the mounting hole 82 of the vehicle body panel 80, and the mounting piece 34 is caught by the inner peripheral edge of the mounting hole 82 when the fixing portion 30 is inserted. Is set to

  Further, a thin-walled portion 37 is formed on the distal end side of the most protruding portion 35 of the attachment piece 34 through a stepped portion 36. As a result, the stepped portion 36 plays a role of retaining the wire mounting structure 20 from being pulled out of the mounting hole 82 after the mounting piece 34 is inserted into the mounting hole 82. Further, since the thin portion 37 comes into contact with the inner peripheral edge of the attachment hole 82 during attachment, a sound is generated.

  In order to insert the fixing portion 30 into the attachment hole 82 of the vehicle body panel 80, the operator applies a force so as to press the attachment piece 34 against the inner peripheral edge portion of the attachment hole 82. At this time, due to the reaction of the force transmitted from the mounting piece 34 to the inner peripheral edge portion of the mounting hole 82, the free end side of the mounting piece 34 contracts toward the shaft portion 32, and the protruding amount of the outermost protruding portion 35 is reduced. When the mounting piece 34 is elastically deformed, the most protruding portion 35 of the mounting piece 34 can pass through the mounting hole 82.

  After the stepped portion 36 of the mounting piece 34 passes through the mounting hole 82, the elastically deformed one starts to return to the original state, and the stepped portion 36 of the mounting piece 34 is caught by the inner peripheral edge of the mounting hole 82. . As a result, the fixed portion 30 is fixed to the mounting hole 82 provided in the vehicle body.

  Here, only one stepped portion 36 is provided by the thin portion 37, but the second thin portion thinner than the thin portion 37 is provided on the distal end side of the thin portion 37, etc. By doing so, a plurality of stepped portions 36 by the thin-walled portion 37 may be provided.

  However, the shape of the mounting piece 34 is not limited to the above. For example, the step portion 36 formed by the thin portion 37 may not be provided, and the distal end portion of the attachment piece 34 may be caught by the inner peripheral edge portion of the attachment hole 82.

  The fitting part 40 is provided on the other end side of the shaft part 32. The fitting part 40 will be described later together with the fitted part 60.

  The main body portion 50 includes a fitted portion 60 and an attachment portion 52. The main body 50 is a portion that is fitted to the fixing portion 30 so as to be relatively rotatable and is fixed to the electric wire 12.

  Here, the attachment portion 52 includes a cylindrical protector 53 that can accommodate the electric wire 12 therein. A fitted portion 60 is provided on the outer peripheral surface of the protector 53. Here, the protector 53 is formed in a cylindrical shape, but may be formed in a rectangular tube shape. Moreover, you may form in the semi-cylinder shape opened along the longitudinal direction.

  In a state where the electric wire 12 is accommodated in the protector 53, the electric wire 12 and a fixing piece provided so as to protrude from the end of the protector 53 are bound with a tape or the like, or a rib is provided in the protector 53. For example, the protector 53 is fixed to the electric wire 12 by bending and holding the electric wire 12. Thereby, the fitted part 60 is fixed to the electric wire 12.

  The to-be-fitted part 60 is formed so that the fitting part 40 can be fitted. One of the fitting portion 40 and the fitted portion 60 includes a spherical portion 71, and the other includes a support portion 70 that can be fitted to the spherical portion 71 so as to be relatively rotatable. Further, here, the support portion 70 is formed with a rotation opening 72 that opens from the spherical portion 71 to the shaft portion 32 side or the attachment portion 52 side.

  Specifically, here, the fitting portion 40 includes a spherical portion 71, and the fitted portion 60 includes a support portion 70. For this reason, here, the fitting part 40 is formed so as to fit inside the fitted part 60. The fixed portion 30 is formed so that the shaft portion 32 extends from the surface of the spherical portion 71.

  Here, the support portion 70 is formed in a hollow spherical shape. As a result, an accommodating recess capable of accommodating the spherical portion 71 is formed in the support portion 70. And the opening part 72 for rotation is formed in a part on the outer peripheral surface of the support part 70 formed in this hollow spherical shape.

  The rotation opening 72 allows the shaft portion 32 (the attachment portion 52 in the first modification described later) to pass through in a state where the spherical portion 71 is accommodated in the support portion 70. Is formed. Further, here, the rotation opening 72 also serves as the insertion opening 74 and is formed so that the spherical portion 71 can be inserted into the rotation opening 72.

  More specifically, the rotation opening 72 is formed in a circular shape by forming a shape such that a part of a hollow sphere is removed. The diameter of the rotation opening 72 formed in a circular shape is set slightly smaller than the diameter of the spherical portion 71, and the rotation opening 72 is formed to be elastically deformable so that the diameter is increased. Yes. Thereby, the fitting part 40 can be inserted into the inside from the opening part 72 for rotation in the state which opened the opening part 72 for rotation. Further, when the fitting portion 40 is housed inside, the elastic deformation amount of the opening 72 for rotation is reduced or the elastic deformation is eliminated, so that the fitting portion 40 is detached from the fitted portion 60. Can be suppressed.

  Here, at least one slit 76 is formed in the support portion 70. Here, four slits 76 are formed at equal intervals. The slits 76 are formed along the outer peripheral surface from the inner peripheral edge of the rotation opening 72 toward the direction away from the rotation opening 72. By forming the slit 76, it is possible to facilitate elastic deformation so as to widen the opening 72 for rotation. As a result, the spherical portion 71 can be easily inserted from the rotation opening 72 into the support portion 70.

  It is not essential that the slit 76 is formed. Further, even when the slits 76 are formed, the number thereof may be one or plural, and is a value set as appropriate. The length of the slit 76 (the dimension from the inner peripheral edge of the rotation opening 72 to the tip of the slit 76) is also a value that is set as appropriate. However, the slits 76 are formed, and the larger the number and the longer the length, the easier the opening 72 for rotation becomes.

  When a plurality of slits 76 are formed, it is not essential that the slits 76 are equally spaced from each other, and the intervals may be different from each other. However, it is possible to suppress the force required when the fitting portion 40 is inserted into the support portion 70 when they are equally spaced from each other.

  Further, the support portion 70 is formed in a spherical shape having an inner peripheral surface having a diameter substantially the same as that of the fitting portion 40. Thereby, the insertion angle of the fixing | fixed part 30 can be changed smoothly by the fitting part 40 and the to-be-fitted part 60 being able to rotate relatively smoothly. Further, rattling can be suppressed in a state where the fitting portion 40 and the fitted portion 60 are fitted.

  Here, the inner peripheral edge portion of the rotation opening 72 also serves as a rotation restricting portion that restricts the amount of relative rotation between the fitting portion 40 and the fitted portion 60. Specifically, here, the shaft portion 32 extending from the spherical portion 71 is rotatable until it comes into contact with the inner peripheral edge of the rotation opening 72. That is, the amount of relative rotation between the fitting part 40 and the fitted part 60 is determined by the diameter of the opening 72 for rotation.

  Here, on the outer peripheral surface of the protector 53, a conventional clip 90 whose insertion direction is fixed is provided separately from the fitted portion 60 and the fixing portion 30 according to the present embodiment. And the insertion direction of the fixing | fixed part 30 is changed so that the insertion direction of the fixing | fixed part 30 and the clip 90 may differ.

  The conventional clip 90 is provided so that the fixing portion is inserted in a direction orthogonal to the extending direction of the electric wire 12. This is because the electric wire 12 is normally fixed to the attachment object 80 in a state along the surface of the attachment object 80. However, in order to fix the electric wire 12 to the attachment object 80 in a state where the electric wire 12 is not along the surface of the attachment object 80, the insertion object of the fixing portion 30 is attached from the direction orthogonal to the extending direction of the electric wire 12. It is necessary to change in a direction perpendicular to the surface of the object 80. The electric wire mounting structure 20 according to the present embodiment enables this by allowing the fixing portion 30 to rotate with respect to the main body portion 50 fixed to the electric wire 12.

<Operation>
Next, an operation for determining the insertion angle of the fixing portion 30 in a state where the fitting portion 40 and the fitted portion 60 are fitted will be described. 6 and 7 are explanatory diagrams illustrating the rotatable range of the fixing unit 30 with respect to the main body unit 50. FIG. 6 is a plan view of the electric wire attachment structure 20 according to the embodiment, and FIG. 7 is a front view of the electric wire attachment structure 20 according to the embodiment.

  As shown in FIG. 6, the fixing portion 30 including the fitting portion 40 can rotate 360 degrees with respect to the fitting portion 60 with the extending direction of the shaft portion 32 as a rotation axis. Thereby, it is possible to freely select a direction in which the fixing portion 30 is inclined in a plane orthogonal to the extending direction of the shaft portion 32.

  Further, here, the fixed portion 30 includes the extending direction of the shaft portion 32 in a state where the shaft portion 32 is located at the center of the rotation opening portion 72 (position P1 in FIG. 7), and the shaft portion 32 is the rotation opening. The rotation opening is provided so that the angle formed by the extending direction of the shaft portion 32 in a state of contact with the inner peripheral edge of the portion 72 (position P2 in FIG. 7) is 45 degrees. That is, the shaft portion 32 is set so as to be capable of rotating 90 degrees around the axis along the direction passing through the center of the fitting portion 40 and orthogonal to the extending direction of the shaft portion 32 with respect to the fitted portion 60.

  Here, the support portion 70 is provided in the protector 53 such that the opening direction of the rotation opening portion 72 of the support portion 70 (the central axis direction of the rotation opening portion 72) is orthogonal to the extending direction of the electric wires 12. ing. For this reason, the fixing portion 30 is inserted in the direction in which the fixing portion 30 is inserted into the electric wire 12 from the direction orthogonal to the extending direction of the electric wire 12 to a direction inclined 45 degrees in all directions.

  The insertion direction of the fixing part 30 with respect to the electric wire 12 can be changed by changing the direction of the opening of the rotation opening 72 of the support part 70. For example, by providing the support portion 70 so that the opening direction of the opening 72 for rotation of the support portion 70 is parallel to the extending direction of the electric wire 12, the insertion direction of the fixing portion 30 is the extending direction of the electric wire 12. From the axis, the direction is inclined 45 degrees in all directions.

  The extending direction of the shaft portion 32 in a state where the shaft portion 32 is located at the center of the rotation opening portion 72 and the extension of the shaft portion 32 in a state where the shaft portion 32 is in contact with the inner peripheral edge portion of the rotation opening portion 72. It is not essential that the angle formed with the current direction is 45 degrees, and it may be smaller or larger than 45 degrees. However, the extending direction of the shaft portion 32 in a state where the shaft portion 32 is located at the center of the rotation opening portion 72 and the extension of the shaft portion 32 in a state where the shaft portion 32 is in contact with the inner peripheral edge portion of the rotation opening portion 72. If the angle formed with the current direction is at least 45 degrees, it is possible to deal with all insertion directions by shifting the direction of the opening of the rotation opening 72 of the support section 70 by 90 degrees. For this reason, it is easy to provide the support portion 70 for obtaining a desired insertion direction.

<Effect>
According to the wire mounting structure 20 according to the present embodiment, one of the fitting portion 40 and the fitting portion 60 includes a spherical portion 71 and the other can be fitted to the spherical portion 71 so as to be relatively rotatable. Since the support part 70 is included, the attachment structure 20 of one electric wire can respond to a plurality of types of insertion angles.

  Moreover, since the inner peripheral surface of the support portion 70 is formed in a spherical shape, the insertion angle can be changed smoothly.

  Further, since at least one slit 76 is formed from the inner peripheral edge of the rotation opening 72 along the outer peripheral surface, the rotation opening 72 can be easily widened. Thereby, the fitting part 40 and the to-be-fitted part 60 can be easily fitted.

  Further, by housing the electric wire 12 in the protector 53, the electric wire mounting structure 20 can be fixed to the electric wire 12.

  Further, since the protector 53 is provided with the conventional clip 90, the fitted portion 60, and the fixing portion 30, the protector 53 can be fixed to two fixing locations having different insertion angles.

{Second Embodiment}
An electric wire mounting structure 20a according to the second embodiment will be described. FIG. 8 is a plan view showing the main body 50a of the electric wire attachment structure 20a according to the second embodiment. FIG. 9 is a side view showing the main body 50a of the electric wire attachment structure 20a according to the second embodiment. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted (the same applies to the following modifications).

  In the electric wire attachment structure 20a according to the second embodiment, the shape of the support portion 70a is different from the shape of the support portion 70 of the electric wire attachment structure 20 according to the first embodiment. Specifically, in the support portion 70a of the electric wire mounting structure 20a according to the second embodiment, a rotation opening 72a and an insertion opening 74a different from the rotation opening 72a are formed and inserted. One formed in a spherical shape can be inserted into the inside of the support portion 70a from the opening 74a for use. Here, the fixing part 30 of the electric wire attachment structure 20a according to the second embodiment is the same as the fixing part 30 of the electric wire attachment structure 20 according to the first embodiment.

  More specifically, the outer shape of the support portion 70a is formed in a shape in which a half cylinder and a rectangular parallelepiped, in which the cylinder is cut in half perpendicular to the bottom surface, are combined. In the half cylinder and the rectangular parallelepiped, a cross section of the half cylinder is connected to one side surface of the rectangular parallelepiped. The inside of the support portion 70a is formed to be hollow.

  The support portion 70a is provided so as to be connected to the mounting portion 52 on the side where the bottom surface on one side is located among the both bottom surfaces of the semicylindrical, and the rotation opening 72a is provided on the side where the bottom surface on the other side is located. .

  An insertion opening 74a is provided on the side surface of the cuboid portion of the support portion 70a opposite to the side surface connected to the half cylinder. Further, here, a pair of elastic pieces 78 extending from the inner peripheral edge portion of the insertion opening 74a toward the inside of the support portion 70a are provided, and the distance between the two becomes narrower toward the distal end side of the pair of elastic pieces 78. It is formed as follows.

  The tip portions of the pair of elastic pieces 78 are not connected, and the distance between the tip portions of the pair of elastic pieces 78 is set to be smaller than the diameter of the spherical portion 71. The pair of elastic pieces 78 can be elastically deformed so that the distal ends thereof are free ends, and the pair of elastic pieces 78 can extend the distance between the distal ends to the same extent as the diameter of the spherical portion 71. As a result, the spherical portion 71 can be inserted into the support portion 70 a from between the pair of elastic pieces 78. Moreover, after inserting the spherical part 71 into the inside of the support part 70a, what was elastically deformed returns, and the fitting state of the fitting part 40 and the to-be-fitted part 60a is eliminated. Can be suppressed.

  The diameter of the bottom surface of the semi-cylindrical part is set to be approximately the same as the diameter of the spherical part 71. Moreover, the diameter of the opening 72a for rotation is set so that it may become smaller than the diameter of the bottom face of a semi-cylindrical part. As a result, even when the spherical portion 71 inserted into the support portion 70a is about to be detached from the rotation opening 72a, the spherical portion 71 is caught on the inner peripheral edge of the rotation opening 72a and is fitted. It can suppress that the fitting state of the part 40 and the to-be-fitted part 60a is eliminated.

  In a state where the spherical portion 71 is inserted into the support portion 70a, the shaft portion 32 extends outwardly from the rotation opening 72a formed on the bottom surface of the semi-cylindrical, and the shaft portion 32 is the rotation opening portion. The fitting portion 40 and the fitted portion 60a can be rotated relative to each other until they contact the inner peripheral edge portion of 72a. As a result, as in the first embodiment, the inner peripheral edge of the rotation opening 72 a also serves as a rotation restricting portion that restricts the amount of relative rotation between the fitting portion 40 and the fitted portion 60. That is, the amount of relative rotation between the fitting portion 40 and the fitted portion 60a is determined by the diameter of the rotation opening 72a.

<Operation>
Next, the operation of determining the insertion angle of the fixing portion 30 in a state where the fitting portion 40 and the fitted portion 60a are fitted will be described. FIG. 10 is an explanatory diagram showing a rotatable range of the fixing portion 30 with respect to the main body portion 50a. FIG. 10 is a partial cross-sectional view seen from the front of the electric wire mounting structure 20a according to the present embodiment.

  Also in the electric wire mounting structure 20a according to the present embodiment, the fixed portion 30 including the fitting portion 40 is a shaft portion with respect to the fitted portion 60a, similarly to the electric wire mounting structure 20 according to the first embodiment. It is possible to rotate 360 degrees with the extending direction of 32 as the axis of rotation. Thereby, it is possible to freely select a direction in which the fixing portion 30 is inclined in a plane orthogonal to the extending direction of the shaft portion 32.

  Further, here, the fixed portion 30 includes the extending direction of the shaft portion 32 in a state where the shaft portion 32 is located at the center of the rotation opening portion 72a (position P3 in FIG. 10), and the shaft portion 32 is the rotation opening. The rotation opening is provided so that the angle formed by the extending direction of the shaft portion 32 in a state of contact with the inner peripheral edge of the portion 72a (position P4 in FIG. 10) is 45 degrees. That is, the shaft portion 32 is set so as to be capable of rotating by 90 degrees around the axis along the direction orthogonal to the extending direction of the shaft portion 32 through the center of the fitting portion 40 with respect to the fitted portion 60a.

<Effect>
Also in the electric wire attachment structure 20a according to the second embodiment, the electric wire attachment structure according to the first embodiment is obtained for effects other than the insertion of the spherical portion 71 from the rotation opening 72a into the support portion 70a. The same effect as 20 can be obtained.

{First modification}
Next, the wire mounting structure 20b according to the first modification will be described. FIG. 11 is a front view showing an electric wire mounting structure 20b according to a first modification.

  The electric wire attachment structure 20b according to the first modification is different in the shapes of the fixing portion 30b and the main body portion 50b from the shapes of the fixing portion 30 and the main body portion 50 of the electric wire attachment structure 20 according to the first embodiment. Specifically, in the electric wire mounting structure 20b according to the first modification, the fitting portion 40 includes the spherical portion 71 and the fitted portion 60 includes the support portion 70 in the first embodiment. Are replaced. That is, here, the fitting portion 40 b includes the support portion 70, and the fitted portion 60 b includes the spherical portion 71.

  More specifically, in the fixing portion 30b, the shaft portion 32 protrudes from the outer peripheral surface of the hollow spherical support portion 70 in which the rotation opening 72 is formed, on the side opposite to the rotation opening 72. Is formed. The main body 50 b is provided with a spherical portion 71 on the outer peripheral surface of the protector 53. And the fitting part 40b and the to-be-fitted part 60b are fitted so that relative rotation is possible by inserting the to-be-fitted part 60b in the fitting part 40b.

  In the case of the first modification, the fixing portion 30 b can rotate with respect to the electric wire 12 until the inner peripheral edge of the rotation opening 72 comes into contact with the outer peripheral surface of the protector 53.

  In addition, the fitting part 40b of the attachment structure 20b of the electric wire which concerns on a 1st modification may include the support part 70a which concerns on 2nd Embodiment instead of the support part 70 which concerns on 1st Embodiment. That is, the shape of the fitting part 40 and the shape of the to-be-fitted part 60 may interchange similarly also in the attachment structure 20b of the electric wire which concerns on 2nd Embodiment.

  The same effect as that of the electric wire attachment structures 20 and 20a according to the first embodiment or the second embodiment can also be obtained by the electric wire attachment structure 20b according to the first modification.

{Second modification}
Next, an electric wire mounting structure 20c according to a second modification will be described. FIG. 12 is a front view showing an electric wire mounting structure 20c according to a second modification.

  The electric wire attachment structure 20c according to the second modification is different from the electric wire attachment structure 20 according to the first embodiment in the shape of the attachment portion 52c of the main body 50c.

  Specifically, the attachment portion 52c of the electric wire attachment structure 20 according to the second modification includes a plate portion 54 formed in a plate shape. And the to-be-fitted part 60 is provided in the one main surface side of the board part 54. As shown in FIG. The plate portion 54 is in contact with the electric wire 12 on the other principal surface side, and the portion where the fitted portion 60 is not provided is wound together with the electric wire 12 by a binding member such as a tape, thereby attaching the electric wire. This is a part for fixing the structure 20 c to the electric wire 12.

  Here, the fitted portion 60 is provided at the center in the longitudinal direction of the plate portion 54, and the binding member can be wound around both ends of the plate portion 54 so as to sandwich the fitted portion 60. That is not essential. For example, the fitted portion 60 may be provided on one end side of the plate portion 54, and the binding member may be wound only on the other end side of the plate portion 54.

  Also in the electric wire attachment structure 20c according to the second modification, the same effects as those of the electric wire attachment structure 20 according to the first embodiment can be obtained with respect to effects other than housing the electric wire 12 inside the protector 53. it can.

{Third modification}
Next, an electric wire mounting structure 20d according to a third modification will be described. FIG. 13: is a front view which shows the attachment structure 20d of the electric wire which concerns on a 3rd modification.

  Similar to the electric wire attachment structure 20c according to the second modification, the electric wire attachment structure 20d according to the third modification is similar to the electric wire attachment structure 20d according to the first embodiment. The shape of the mounting portion 52 is different.

  Specifically, the attachment part 52d of the electric wire attachment structure 20d according to the third modified example is connected to the band part 55 formed in a band shape and one end part of the band part 55 and the other end part of the band part 55 And a band fixing part 57 provided with a fitted part 60 on the opposite side to the band part 55.

  A plurality of recesses 56 that can selectively lock a band locking portion 59 described later are formed on at least one of the inner peripheral surface and the outer peripheral surface (here, the outer peripheral surface) of the band portion 55. Yes. Here, each recess 56 of the plurality of recesses 56 is sequentially formed at regular intervals along the longitudinal direction of the band portion 55 on the distal end side of the band portion 55. It is not essential that the interval between the recesses 56 is constant. Further, here, the concave portion 56 is not formed in the vicinity of the front end side portion of the band portion 55. More specifically, the shape of each recess 56 is formed to be recessed toward the center of the band portion 55 in the thickness direction.

  Here, the band fixing portion 57 is formed in a rectangular parallelepiped shape, and the fitted portion 60 is provided on the surface opposite to the surface from which the band portion 55 protrudes while the band portion 55 protrudes from one surface. The band fixing part 57 includes a band insertion part 58 and a band locking part 59.

  The band insertion part 58 is formed with an insertion hole 58a through which the band part 55 can be inserted. Here, the band insertion part 58 is formed in a rectangular tube shape that opens to both ends, and a rectangular hole-shaped insertion hole 58a is formed therein. The width dimension of the insertion hole 58 a is larger than the width dimension of the band part 55, and the height dimension of the insertion hole 58 a is larger than the thickness dimension of the band part 55. After the band portion 55 is wound around the electric wire 12, the band portion 55 is inserted into the insertion hole 58 a from the one end side opening of the band insertion portion 58 toward the other end side opening. Here, the band insertion part 58 and the insertion hole 58a are formed by forming a hole having a quadrangular cross section through a pair of side surfaces orthogonal to the surface of the band fixing part 57 from which the band part 55 projects.

  The band locking portion 59 is configured to be selectively lockable with a plurality of concave portions 56 provided on one surface of the band portion 55. Here, the band locking portion 59 is formed in a protruding shape that protrudes from the inner peripheral surface of the band insertion portion 58 on the fitted portion 60 side, and is selectively formed in a concave portion 56 provided on the outer peripheral surface of the band portion 55. It can be locked.

  The width dimension of the band locking portion 59 is set to be the same as or smaller than the width dimension of the recess 56 (here, slightly smaller). The height dimension of the band locking portion 59 is set to be the same as or larger than the depth dimension of the recess 56 (here, slightly larger).

  Here, the operation of locking the band part 55 between the band part 55 and the band fixing part 57 will be described.

  First, the band portion 55 is inserted through the insertion hole 58a from the tip side portion. At this time, when the tip side portion where the concave portion 56 is not provided passes through the band locking portion 59, the band locking portion 59 is elastically deformed and the band portion 55 is inserted to the portion where the concave portion 56 is provided. Is done. When the portion where the concave portion 56 is formed is inserted up to the band locking portion 59, the band locking portion 59 returns from the elastically deformed state and enters the concave portion 56.

  If the band portion 55 is further inserted in this state, the band portion 55 and the band locking portion 59 are elastically deformed, and the band portion 55 can be inserted.

  On the other hand, the band part 55 and the band locking part 59 are hooked in the direction in which the band part 55 is pulled out from the insertion hole 58a, and is brought into a removal-prevented state.

  By inserting the band part 55 into the insertion hole 58a until the band part 55 tightens the electric wire 12 and cannot be inserted, the band part 55 does not move in either direction and is locked. Thus, the band portion 55 can be locked to the band fixing portion 57 in a state where the band portion 55 is wound around the electric wire 12 so that the band portion 55 tightens the electric wire 12.

  At this time, the extra length portion of the band portion 55 that has passed through the band locking portion 59 can be prevented from being interfered with other members by being cut.

  The band locking portion 59 may be formed so as to enter only one recess 56 at a time, or may be formed so as to enter two or more recesses 56 at the same time. If the band locking portion 59 is formed so as to enter the two or more recesses 56 at the same time, the locking state (prevention state) of the band portion 55 becomes stronger.

  But the structure which fixes the band part 55 to the band fixing | fixed part 57 is not restricted above. For example, the concave portion 56 may be provided on the side portion of the band portion 55, and the band locking portion 59 may be provided on the inner peripheral side surface of the band insertion portion 58. That is, it is only necessary that the band portion 55 can be fixed to the band fixing portion 57 in order from the front end side of the band portion 55 in a state where the band portion 55 is wound around the electric wire 12.

  Also with the electric wire attachment structure 20 according to the third embodiment, the same effects as those of the electric wire attachment structure 20 according to the first embodiment can be obtained for effects other than the housing of the electric wire 12 in the protector 53. .

  In addition, each structure demonstrated by said each embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
