  By the way, in the electric power feeder which has the above rocking | fluctuation structures, a wire harness follows a slide member, curving, when a slide member moves. And in the field | area of the above electric power feeders, the curve control member which is arrange | positioned along a wire harness and controls the curve may be provided.

  At this time, some of the bending regulating members are molded with a resin material. In such a type of bending restricting member, when the wire harness restricts unnecessary bending when following the slide member, abnormal noise may occur due to burrs caused by mold forming.

  Therefore, the present invention pays attention to the above-described problems, and a bending restriction member mold capable of forming a bending restriction member in which the generation of abnormal noise is suppressed, and such a bending restriction member mold are applied. It is an object of the present invention to provide a curved regulating member and a power feeding device.

And a plurality of member pieces having an inner surface shape corresponding to the outer shape of the plurality of member pieces and an inner shape corresponding to the outer shape of each of the plurality of member pieces. A recess is formed, and is combined with the inner mold, thereby providing an outer mold that defines a filling space of the resin material corresponding to each of the plurality of member pieces, and the inner mold includes the outer mold The plurality of recesses in the mold Wherein the convex portion of each of the inner surface is fitted to the inside of each of the plurality of recesses while being in contact with the opening edge portion of the inner mold side.

  The bending restricting member mold according to a second aspect is the bending restricting member mold according to the first aspect, wherein the convex portion is only in the vicinity of the opening edge portion in the length direction of the wire harness. It is formed in the shape fitted in each inside of several recessed part.

  Further, the bending restriction member according to the third aspect of the present invention is arranged along the wire harness, and a plurality of member pieces each provided with an accommodation groove in which the wire harness is accommodated, and the adjacent member pieces. And a flexible connecting portion that connects the adjacent member pieces to each other so that the bending of the wire harness on a predetermined plane is restricted, and the bending restriction is molded with a resin material. In the case where a burr resulting from mold forming is formed on the edge in the length direction of the wire harness in each of the plurality of member pieces, the burr is arranged inside the receiving groove. It is characterized by standing up towards.

  The bending restriction member according to a fourth aspect is the bending restriction member according to the third aspect, wherein each of the plurality of member pieces is closer to the inside of the receiving groove than the other part in the vicinity of the edge. A step is formed on the opposite side.

  A power supply apparatus according to a fifth aspect of the present invention is a power supply apparatus that electrically connects the vehicle body and the slide member in a vehicle having a vehicle body and a slide member, the vehicle body and the slide member. A wire harness routed between the wire harness and the third or fourth bending regulating member arranged along the wire harness.

  In the bending restricting member mold according to the first aspect, a plurality of convex portions provided on the inner mold are in contact with the opening edge portions on the inner mold side on the inner surfaces of the plurality of concave portions of the outer mold. It fits inside each recess. When the bending restriction member is formed by filling the filling space with the resin material, the burr formed by the mold molding is a boundary between the opening edge portion in the concave portion of the outer mold and the convex portion of the inner mold. It is formed of a resin material that has entered the part. This burr is in a state of rising toward the inside of the housing groove at the filling space, that is, at the end edge in the length direction of the wire harness in each member piece of the bending regulating member.

  Here, the burr that causes abnormal noise generation in the bending regulating member is a burr that protrudes from the end edge of each member piece toward the adjacent member piece in the length direction of the wire harness. .

Generation of sound can be suppressed.

  Further, according to the bending restricting member of the fourth aspect, the burr that rises toward the inside of the accommodation groove as described above rises from the step that has been lowered as described above. As a result, the interference between the wire harness that fits in the housing groove and the burr is suppressed by the depth of the step. As described above, according to the bending restricting member of the fourth aspect, it is possible to suppress the degree of interference between the burr and the wire harness resulting from the molding.

  Moreover, according to the electric power feeding apparatus of the said 5th aspect, since the said 3rd or 4th curve control member is applied, generation | occurrence | production of the noise in a curve control member can be suppressed.

  Hereinafter, a bending restricting member mold, a bending restricting member, and a power feeding device according to an embodiment of the present invention will be described. First, the bending restriction member and the power feeding device will be described.

  FIG. 1 is a diagram illustrating a power feeding device to which a bending regulating member according to an embodiment of the present invention is applied. The power feeding device 1 according to the present embodiment is electrically connected via a wire harness 110 routed between the vehicle body 60 and the slide door 50 in the vehicle 5 having the vehicle body 60 and the slide door 50 (slide member). Device. In FIG. 1, the right side in the figure corresponds to the front side of the vehicle 5, the left side in the figure corresponds to the rear side of the vehicle 5, the upper side in the figure corresponds to the outside of the vehicle 5, and the lower side in the figure corresponds to the vehicle 5. It corresponds to the inside. Also, the vertical direction in the figure is the X direction in the present embodiment, the horizontal direction in the figure is the Y direction in the present embodiment, and the direction perpendicular to the paper surface is the Z direction.

  In the power feeding device 1, electric power is supplied from a power source (not shown) provided on the vehicle body 60 to an electric device (not shown) provided on the slide door 50 via the wire harness 110. In the power supply device 1, electrical signals are also exchanged between the control means (not shown) provided on the vehicle body 60 and the electric equipment (not shown) provided on the slide door 50 via the wire harness 110. The power feeding device 1 includes a wire harness 110, a corrugated tube 120, a bending restriction member 130, a door side holding part 140, and a vehicle body side holding part 150.

  As shown in FIG. 4 to be referred to later, the wire harness 110 is obtained by bundling a plurality of covered electric wires 111 with a tape or the like. In the wire harness 110, a portion between the vehicle body 60 and the slide door 50 in the wire harness 110 is passed through a corrugated tube 120 that is a flexible tube made of a resin material. The bending regulating member 130 is disposed between the inner surface of the corrugated tube 120 and the wire harness 110 so as to surround the wire harness 110 in the circumferential direction and along the wire harness 110. The bending restricting member 130 will be described in detail later.

  One end of the corrugated tube 120 on the slide door 50 side is held by the door-side holding unit 140 so as to be swingable on the XY plane with the Z direction, which is the vertical direction of the vehicle 5, as the swing axis direction. The door side holding part 140 is fixed to the slide door 50. The door-side swing shaft 141 along the Z direction provided in the door-side holding unit 140 is parallel to the slide door 50 and orthogonal to the opening / closing direction D11 of the slide door 50 (Y direction which is the front-rear direction of the vehicle 5). It is the axis. One end of the corrugated tube 120 on the slide door 50 side is held by the door-side holding portion 140 so as to be swingable around the door-side swing shaft 141. By holding the corrugated tube 120 by the door-side holding part 140, a part of the wire harness 110 on the slide door 50 side is held swingably on the XY plane around the door-side swing shaft 141. The slide door 50 side of the wire harness 110 protrudes from one end of the corrugated tube 120 on the slide door 50 side. Furthermore, the wire harness 110 extends from the door-side holding part 140 through an unillustrated passage inside the door-side holding part 140 and then extends to the electrical device of the slide door 50.

  On the other hand, one end of the corrugated tube 120 on the vehicle body 60 side is held by the vehicle body side holding portion 150 so as to be swingable on the XY plane with the Z direction, which is the vertical direction of the vehicle 5, as the swing axis direction. The vehicle body side holding part 150 is fixed to the vehicle body 60. A vehicle body side swing shaft 151 along the Z direction provided in the vehicle body side holding portion 150 is an axis parallel to the slide door 50 and perpendicular to the opening / closing direction D11 of the slide door 50. One end of the corrugated tube 120 on the vehicle body 60 side is held by the vehicle body side holding portion 150 so as to be swingable about the vehicle body side swing shaft 151. By holding the corrugated tube 120 by the vehicle body side holding portion 150, a part of the wire harness 110 on the vehicle body 60 side is held so as to be swingable around the vehicle body side swing shaft 151 on the XY plane. The vehicle body 60 side of the wire harness 110 exits from one end of the corrugated tube 120 on the vehicle body 60 side, and further passes through a passage (not shown) inside the vehicle body side holding portion 150 and also exits from the vehicle body side holding portion 150. The vehicle body 60 extends to a power source and control means (not shown).

  When the sliding door 50 is fully closed, the door-side holding portion 140 is located on the front side of the vehicle 5 with respect to the vehicle body-side holding portion 150 as shown in FIG. The corrugated tube 120, that is, the wire harness 110 inside the corrugated tube 120, extends in a substantially linear state between the vehicle body side holding portion 150 and the door side holding portion 140.

  When the slide door 50 is opened in the opening direction D111 toward the rear of the vehicle 5, at the initial stage, one end of the corrugated tube 120 on the slide door 50 side swings as follows. That is, the one end swings on the XY plane so as to move away from the slide door 50 and toward the front side of the vehicle 5 in the direction opposite to the opening direction D111. The door side holding part 140 is provided with a coil spring to promote such swinging. The coil spring urges one end of the corrugated tube 120 on the slide door 50 side in the urging direction D12 that is separated from the slide door 50 and is directed in the direction opposite to the opening direction D111 of the slide door 50.

  By swinging as described above in the initial stage of opening the sliding door 50, the wire harness 110 inside the corrugated tube 120 is next moved during the subsequent movement of the sliding door 50 in the opening direction D111, that is, when the sliding door 50 is half open. Bend like That is, as shown in FIG. 1, the wire harness 110 draws a U-shape on the XY plane so as to protrude from the vehicle body side holding portion 150 to the door side holding portion 140 on the front side of the vehicle 5. It bends in the permissible direction D13 and curves toward the outside of 60.

  In the following description, the wire harness 110 inside the corrugated tube 120 may be simply referred to as the wire harness 110 without particular notice.

  The U-shaped curve as described above reduces the burden on the corrugated tube 120 and the wire harness 110 compared to, for example, the case where the wire harness 110 is bent into an S shape on the XY plane.

  During movement of the sliding door 50 in the opening direction D111, the arm on the sliding door 50 side in the U-shape of the wire harness 110 moves toward the front side of the vehicle 5 by the urging in the urging direction D12 by the door side holding portion 140. And straightened. At this time, the arm on the vehicle body 60 side is extended linearly toward the front side of the vehicle 5. The U shape of the wire harness 110 on the XY plane of the wire harness 110 during the movement of the slide door 50 is adjusted by the behavior of each part and the action of the bending restriction member 130 described later.

  As the slide door 50 moves in the opening direction D111, the arm on the slide door 50 side in the U-shape of the wire harness 110 extends and the arm on the vehicle body 60 side shortens. Then, when the arm on the vehicle body 60 side is shortened to some extent, one end on the vehicle body 60 side of the wire harness 110 swings in the swing direction D15 toward the rear side of the vehicle 5. Thereafter, in this state, the slide door 50 moves in the opening direction D111 and reaches the fully open state.

  When the sliding door 50 is closed in the closing direction D112 from the fully opened state, the wire harness 110 follows the reverse operation to that when the sliding door 50 is opened. First, at the initial stage, one end of the wire harness 110 on the vehicle body 60 side swings in a direction opposite to the swing direction D15, so that the wire harness 110 becomes U-shaped on the XY plane. Thereafter, when the sliding door 50 continues to move in the closing direction D112 and the arm on the sliding door 50 side in the U-shape is shortened to some extent, one end on the sliding door 50 side of the wire harness 110 swings as follows. . That is, at this stage, one end of the wire harness 110 on the slide door 50 side is opposed to the urging by the door-side holding portion 140 and is opposite to the urging direction D12 to the rear side of the vehicle 5. Swing. Thereafter, in this state, the slide door 50 moves in the closing direction D112, and the wire harness 110 reaches the fully closed state while being extended in a straight line state.

  Here, the end on the slide door 50 side of the floor of the vehicle body 60 is lowered one step, and is a step 61 in which the occupant puts his or her feet when boarding. When the sliding door 50 is opened and closed, the arm on the vehicle body 60 side of the U-shaped wire harness 110 as described above passes near the step 61 on the XY plane.

  At this time, generally, in the field of a power feeding device attached to a slide door of a vehicle, there is a demand for suppressing swelling to the vehicle body side when the wire harness is bent when the slide door is opened and closed. Therefore, in the present embodiment, a bending regulating member 130 arranged along the wire harness 110 is provided in order to regulate the bending that causes the wire harness 110 to bulge toward the vehicle body 60 in this way. The bending regulating member 130 restricts the wire harness 110 to bend on the XY plane. Then, the bending restriction member 130 allows the bending in the allowable direction D13 in which the wire harness 110 is bent toward the outside of the vehicle body 60 on the XY plane. On the other hand, with respect to the regulation direction D16 that bends the wire harness 110 to the inside of the vehicle body 60 on the side opposite to the permissible direction D13, the bending beyond a predetermined limit state is regulated.

  FIG. 2 is a view showing the bending restriction member shown in FIG. 1, and FIG. 3 shows the structure of the bending restriction member in detail with a part of the bending restriction member shown in FIG. 2 as a representative example. It is a perspective view shown in FIG. 4 is a cross-sectional view showing a cross section taken along line V11-V11 in FIG.

  The bending regulating member 130 is disposed between the inner surface of the corrugated tube 120 and the wire harness 110 so as to surround the wire harness 110 in the circumferential direction and be along the wire harness 110 to induce the bending. The bending regulating member 130 has substantially the same length as the corrugated tube 120. In FIG. 2, the bending regulating member 130 is shown in a circular shape, and the upper end in the drawing is the vehicle body 60 side, and the lower end is the slide door 50 side.

  The bending regulating member 130 includes a plurality of member pieces 131 arranged along the wire harness 110 and a connecting portion 132 that connects the plurality of member pieces 131 adjacent to each other. In this embodiment, the several member piece 131 and the connection part 132 are mutually shape | molded integrally with the resin material. The connecting portion 132 is a flexible member that is disposed along the wire harness 110 so as to be positioned inside the curved shape when the wire harness 110 is bent in this way.

  Each of the plurality of member pieces 131 includes a pair of opposing walls 1311 facing each other so as to sandwich the wire harness 110 therebetween, and a pair of opposing walls 1311 as shown in a representative example in FIG. A connecting wall 1312 to be connected. Each member piece 131 is formed by these three walls so that the cross-sectional shape intersecting the length direction D14 of the wire harness 110 is substantially C-shaped as shown in FIGS.

  The plurality of member pieces 131 are arranged along the wire harness 110 so that the end surfaces 1311a of the facing walls 1311 of the member pieces 131 face each other. The plurality of member pieces 131 are such that when the connecting wall 1312 connecting the pair of opposing walls 1311 is bent in the curved shape of the wire harness 110, that is, in the allowable direction D13 as shown in FIGS. Are arranged so as to be located inside the curved shape. And the connection part 132 has connected the coupling walls 1312 of the member piece 131 adjacent to each other.

  In each member piece 131, a space defined by a pair of opposing walls 1311 and a coupling wall 1312 opens toward the outer side of the curved shape, and serves as an accommodation groove 1313 in which the wire harness is accommodated.

  The connecting portion 132 is a plate-like member as shown in FIGS. 3 and 4, and is formed thin with a thickness that can be bent in either the allowable direction D13 or the opposite direction in FIG. Has been. Furthermore, the bending restricting member 130 is arranged such that the plate-like connecting portion 132 is orthogonal to the XY plane shown in FIG. As a result, the bending of the bending regulating member 130 is limited on the XY plane, and as a result, the bending of the wire harness 110 is also limited on the XY plane.

  Further, the member piece 131a located at the end of the bending regulating member 130 on the vehicle body 60 side is held together with the end of the corrugated tube 120 by the vehicle body side holding portion 150 shown in FIG. On the other hand, the member piece 131b located at the opposite end of the bending restricting member 130, that is, the end on the slide door 50 side, is not held by the door side holding portion 140 shown in FIG. Accordingly, the member piece 131b can be brought into contact with and separated from the door-side holding portion 140 in accordance with the bending of the bending restriction member 130. The member piece 131a on the vehicle body 60 side is provided with a flange 131a-1 for holding the member piece 131a on the vehicle body side holding portion 150.

  The bending restricting member 130 is limited to bend on the XY plane shown in FIG. 1, and can be bent in the allowable direction D13 on the XY plane. The bending regulating member 130 is incapable of bending beyond a limit state described later in a regulating direction D16 that is directed to the inside of the vehicle body 60 on the side opposite to the allowable direction D13.

  In the permissible direction D13, as shown in FIG. 3, the connecting portions 132 bend while the adjacent ones of the plurality of member pieces 131 at the curved portions are separated from each other on the side opposite to the connecting portion 132. The bending regulating member 130 can be bent. Thereby, the wire harness 110 is allowed to bend in the allowable direction D13.

  On the other hand, with respect to the regulation direction D16, adjacent ones of the plurality of member pieces 131 at the curved portions abut against each other on the side opposite to the connecting portion 132, so that the bending regulation member 130 cannot be bent beyond the limit state. It has become. A state in which adjacent ones in the curved portion are in contact with each other is a limit state in bending in the restriction direction D16, and the bending restriction member 130 cannot bend in the restriction direction D16 beyond this limit state. As a result, the wire harness 110 is restricted from bending in the restriction direction D <b> 16 so as to bend beyond the limit state in the bending restriction member 130.

  In the present embodiment, the arrangement direction of the plurality of member pieces 131 (that is, the length direction D14 of the wire harness 110), except for a part in the vicinity of the vehicle body side holding portion 150 to be described later, has a substantially full length including the middle. The bending regulating member 130 is configured as follows. That is, it is configured such that when the bending regulating member 130 is in a substantially linear state over the substantially entire length of the above portion, the adjacent member pieces 131 are in contact with each other on the side opposite to the connecting portion 132. That is, in the present embodiment, the limit state of the regulation direction D16 is set to a substantially linear state for a portion excluding a part in the vicinity of the vehicle body side holding portion 150. Thereby, a substantially linear shape is maintained except the part which curves in the allowable direction D13 in the wire harness 110.

  Here, as shown in FIG. 1, in the present embodiment, the swing range on the XY plane of the end portion of the wire harness 110 in the vehicle body side holding portion 150 in the regulation direction D16 is as follows. It has become. That is, the swing range is a range in which the end portion of the wire harness 110 stops before one step of moving the wire harness 110 in parallel with the opening / closing direction D11 of the slide door 50. For this reason, in the present embodiment, the bending restriction member 130 is configured so that a part of the vicinity of the vehicle body side holding portion 150 can be bent to some extent in the restriction direction D16 by slightly relaxing the restriction on the bending in the restriction direction D16. Has been. As a result, a part of the wire harness 110 in the vicinity of the vehicle body side holding portion 150 is slightly curved in the regulation direction D16, and the portion in which the substantially linear shape is maintained as described above is parallel to the opening / closing direction D11 of the slide door 50. Can be directed to.

  The limit state as described above in the bending in the restriction direction D16 of the bending restriction member 130 is adjusted by the interval between the member pieces 131. That is, the limit state is set to a substantially linear state by setting the interval between the member pieces 131 when the bending regulating member 130 is in a substantially linear state to be substantially zero. In addition, by making the gap between the member pieces 131 open even when the substantially straight state is established, the bending restricting member 130 exceeds the substantially straight state to the limit state where the member pieces 131 come into contact with each other. It becomes possible to bend to D16, and the regulation is relaxed.

  In the present embodiment, such a bending regulating member 130 is molded with a resin material.

  FIG. 5 is a schematic diagram showing a bending restricting member mold for forming the bending restricting member shown in FIGS. 1 to 4.

  The bending restricting member mold 7 includes an inner mold 71 and a pair of outer molds 72 disposed with the inner mold 71 interposed therebetween. The inner mold 71 has an outer surface shape corresponding to the accommodation groove 1313 in the member piece 131. The outer mold 72 is formed with a plurality of recesses 721 having an inner surface shape corresponding to the outer shape of the member piece 131, and is combined with the inner mold 71 to partition the resin material filling space 7 a corresponding to the member piece 131. . After the filling space 7a is filled with a resin material and cured, the bending regulating member mold 7 is removed, whereby the bending regulating member 130 is formed. The inner mold 71 is pulled out in a pulling direction D17 perpendicular to the paper surface of FIG. 5, and the pair of outer molds 72 is removed in a removing direction D18 away from the inner mold 71.

  Here, the inner mold 71 has a convex portion that is fitted inside each of the plurality of recesses 721 while being in contact with the opening edge portion 721 a on the inner mold 71 side on the inner surface of each of the plurality of recesses 721 of the outer mold 72. 711 is provided. And this convex part 711 is formed in the shape fitted in each of several recessed part 721 only in the vicinity of the opening edge part 721a about the length direction D14 of the wire harness 110.

  The portion for forming the pair of opposing walls 1311 of each member piece 131 occupies most of the resin material filling space 7 a in the bending restricting member mold 7. FIG. 5 schematically shows a portion for forming the facing wall 1311 in the filling space 7a. And the convex part 711 of the inner metal mold | die 71 is provided in the position corresponded to the both ends edge of the length direction D14 of the wire harness 110 in each opposing wall 1311. Thus, a step 1311b is formed at both end edges of the opposing wall 1311 of each member piece 131 of the bending regulating member 130 as shown in FIG.

  FIG. 6 is a schematic view showing the member pieces shown in FIG. 3 with emphasis on the steps formed at both end edges of the opposing wall.

  As shown in FIG. 3 and FIG. 6, the step 1311 b is formed in the vicinity of both end edges 1311 b-1 of the pair of opposing walls 1311 in the member piece 131. Each level | step difference 1311b becomes the shape where the vicinity of each edge 1311b-1 fell in the step shape on the opposite side to the inner side of the accommodation groove 1313 rather than the other part. The convex portion 711 of the inner mold 71 described above corresponds to the step 1311b in the vicinity of both end edges 1311b-1 of the opposing wall 1311.

  Here, in the bending restricting member mold 7 of the present embodiment shown in FIG. 5, the convex part 711 of the inner mold 71 is the opening edge on the inner mold side on the inner surface of the concave part 721 of the outer mold 72. It fits in the inside of the recessed part 721, contacting the part 721a. Here, when the filling space 7 a of the bending restricting member mold 7 is filled with the resin material to form the bending restricting member 130, the filled resin material is opened at the opening edge in the recess 721 of the outer die 72. There is a possibility of entering the boundary between the portion 721a and the convex portion 711 of the inner mold 71. When the infiltrated resin material is cured, the following burr is formed on the bending regulating member 130.

  FIG. 7 is a schematic diagram showing burrs generated in the bending restricting member formed by the bending restricting member mold shown in FIG. 5.

  The burr 131c made of a resin material that has entered the boundary portion is formed at the end of the filling space 7a, that is, each member piece 131 of the bending regulating member 130 in the length direction D14 of the wire harness 110. More specifically, each of the pair of opposing walls 1311 is formed at both end edges 1311b-1 in the length direction D14. Further, the burr 131c rises from the step 1311b in the vicinity of both end edges 1311b-1 toward the inside of the housing groove 1313 of the wire harness 110.

  FIG. 8 is a schematic view showing a comparative example for comparison with the bending restricting member mold shown in FIG. 5, and FIG. 9 is a bending restricting member die of the comparative example shown in FIG. It is a schematic diagram which shows the burr | flash which arises in the curvature control member formed with the type | mold.

  The bending restricting member mold 8 of the comparative example shown in FIG. 8 is similar to the bending restricting member mold 7 shown in FIG. 5 in that the inner mold 81 and the inner mold 81 are mutually connected. And a pair of outer molds 82 disposed between the two. The outer mold 82 has a plurality of recesses 821 and is combined with the inner mold 81 to partition the filling space 8a of the resin material. However, in the bending restriction member mold 8 of this comparative example, the bending restriction shown in FIG. 5 is that the inner mold 81 is not formed with a convex portion that fits into the concave portion 821 of the outer mold 82. This is different from the member mold 7.

  When the filling space 8a is filled with a resin material and cured, a curve regulating member 930 of a comparative example as shown in FIG. 9 is formed. Similar to the curve regulating member 130 shown in FIG. 7, the curve regulating member 930 of this comparative example includes a plurality of member pieces 931 having a pair of opposed walls 9311. However, in the bending restricting member 930 of this comparative example, since the above-mentioned convex part is not formed in the inner mold 81, a step is formed in the vicinity of both end edges 9311b-1 in the length direction D94 of the wire harness. Absent.

  Here, when the resin material is filled in the filling space 8a of the bending restriction member mold 8 of the comparative example to form the bending restriction member 930 of the comparative example, the filled resin material is the outer mold 82. There is a possibility of entering the boundary between the periphery of the opening in the recess 821 and the surface of the inner mold 81. When the infiltrated resin material is hardened, the following burr shown in FIG. 9 is formed on the curve regulating member 930 of the comparative example. The burr 931c is formed at both end edges 9311b-1 in the length direction D94 of the wire harness in each of the opposing walls 9311. And this burr | flash 931c will be in the state protruded toward each adjacent member piece 931 from each edge 1311b-1. When such a burr 931 regulates the bending by adjoining the adjacent member pieces 931 in the curve regulating member 930 of the comparative example, the adjacent member piece 931, the burr 931c generated in the member piece 931, etc. May cause noise.

  On the other hand, according to the bending restricting member mold 7 of the present embodiment shown in FIG. 5, as shown in FIG. 7, the burr 131 c generated at the end edge 1311 b-1 of each member piece 131. Is in a state of rising toward the inside of the accommodation groove 1313. For this reason, even if adjacent member pieces 131 are close to each other, interference between the burr 131c rising from the end edge 1311b-1 and the adjacent member piece 131 or the burr 131c generated on the member piece 131 as described above. As a result, the generation of abnormal noise is suppressed. Thus, according to the bending restricting member mold 7 of the present embodiment, it is possible to form the bending restricting member 130 in which the generation of abnormal noise is suppressed.

  Further, according to the bending restricting member mold 7 of the present embodiment, the edge 1311b of each member piece 131 is formed by the convex portion 711 of the inner die 71 that is fitted into the concave portion 721 only in the vicinity of the opening edge portion 721a. A step 1311b is formed in the vicinity of -1. For this reason, the burr 131c rises from the step 1311b. The following effects can be obtained when the burr 131c rises from the step 1311b.

  FIG. 10 is a schematic diagram showing the effect obtained when the burr shown in FIG. 7 rises from a step near the edge of each member piece.

  When the burr 131c rises from each member piece 131, that is, the step 1311b in the vicinity of the edge 1311b-1 of the opposing wall 1311, the interference between the wire harness 110 and the burr 131c that fits in the receiving groove 1313 is caused by the step 1311b. It will be suppressed by the depth. Thus, according to the metal mold | die 7 for curvature control members of this embodiment, the grade of interference with the burr | flash 131c and the wire harness 110 resulting from metal mold | die shaping | molding can also be suppressed.

  Further, by setting the height of the convex portion 711 of the inner mold 71, that is, the depth of the step 1311b in each member piece 131 to be formed, to be higher than the height assumed for the burr 131c, the burr 131c. And the wire harness 110 can be substantially avoided.

  In the bending restriction member 130 of the present embodiment formed by the bending restriction member mold 7, even if the adjacent member pieces 131 are close to each other, the burr 131 c and the adjacent member piece 131 or the burr 131 c interfere with each other. As a result, the generation of abnormal noise can be suppressed.

  Further, according to the bending restriction member 130 of the present embodiment, the interference between the wire harness 110 and the burr 131c can be suppressed by the depth of the step 1311b.

  Further, according to the power supply device 1 of the present embodiment shown in FIG. 1 to which such a bending restriction member 130 is applied, it is possible to suppress the generation of abnormal noise in the bending restriction member 130, and Interference with the burr 131c can also be suppressed.
