[0011] In the following description, of the first, second, and third directions that intersect with one another, the first direction will be referred to as the "axial direction X," the second direction will be referred to as the "width direction Y," and the third direction will be referred to as the "height direction Z." Here, the axial direction X, width direction Y, and height direction Z are perpendicular to one another. The axial direction X corresponds to the axial direction of the electric wire or the direction in which the electric wire extends. The width direction Y and height direction Z correspond to intersecting directions that intersect with the axial direction X. Furthermore, unless otherwise specified, each direction used in the following description represents the direction when the respective parts are assembled together. Note that orthogonal here includes nearly orthogonal.

[0012] An electric wire fastening device and a wire harness according to a first embodiment will be described.

[0013] As shown in FIG. 1 , an electric wire fastening device 1 according to the first embodiment is a device for fastening an electric wire W to be routed in a vehicle to the vehicle, and is mounted on the vehicle for use. The electric wire W constitutes a wire harness WH that connects electrical devices installed in the vehicle. The electrical devices include an electronic control device, a sensor, a circuit device, a motor, a battery, etc. The wire harness WH includes an electric wire W and the electric wire fastening device 1.

[0014] The electric wire fastening device 1 includes a protector 2 and a clamp 3. The protector 2 is an electric wire protection member that covers the outer periphery of the electric wire W and is attached to the electric wire W via a cylindrical or tubular member that houses the electric wire W. The clamp 3 is a fixing member that is fixed to a vehicle and fixes the electric wire W to the vehicle via the protector 2. The clamp 3 has an annular portion 31 and a fixing portion 32. The annular portion 31 is a portion for fixing to the protector 2 and is, for example, cylindrical and attached to the outer periphery of the outer surface 2A of the protector 2. The fixing portion 32 is a portion for fixing to the vehicle and is formed integrally with the annular portion 31 and has a fixing hole 32A. For example, the fixing portion 32 fixes the clamp 3 to the vehicle by inserting a fixing member such as a stud bolt that protrudes from the vehicle body into the hole 32A. When the fixing portion 32 is fixed to the vehicle, the protector 2 and the electric wire W are fixed to the vehicle. In addition, the clamp 3 may have a structure for fixing to the vehicle other than the fixing portion 32 described above, as long as it can be fixed to the vehicle.

[0015] The electric wires W are inserted inside the bent pipe 41 and the straight pipe 42, and protectors 2 are attached to the outer peripheries of the bent pipe 41 and the straight pipe 42. For example, two electric wires W are provided and housed inside the bent pipe 41 and the straight pipe 42, respectively. The two electric wires W are restrained together by a restraining member 43 such as tape, and connectors or the like are attached to each end to function as a wire harness. Note that the number of electric wires W provided inside the bent pipe 41 and the straight pipe 42 may be one, or three or more.

[0016] The bent pipe 41 is a bendable pipe, such as a bellows-shaped corrugated tube. The bent pipe 41 has convex portions 41A and concave portions 41B formed alternately on its outer periphery along the axial direction X. The straight pipe 42 is, for example, a hard tube, which extends straight and is configured to be more rigid and less prone to bending than the bent pipe 41. For example, the straight pipe 42 is provided on the outer periphery of the bent pipe 41 and is coaxial with the bent pipe 41. In this case, the bent pipe 41 may be provided only at the end of the straight pipe 42, or may be provided throughout the entire installation area of the straight pipe 42. The electric wire W is routed linearly in the portion where the straight pipe 42 is provided, and is routed bent or curved in the portion where only the bent pipe 41 is provided. In the electric wire fastening device 1, for example, the bent pipes 41 and the straight pipes 42 are arranged alternately in the extension direction. That is, the bent pipes 41 and the straight pipes 42 are arranged alternately around the outer periphery of the tubular member to which the protector 2 is attached. The protector 2 is attached to the boundary between the bent pipe 41 and the straight pipe 42 to cover the outer periphery of the bent pipe 41 and the straight pipe 42, and holds the straight pipe 42 by inserting it into the attachment position of the clamp 3.

[0017] 2 and 3, the protector 2 is cylindrical and includes a main body 21 and a lid 22. The main body 21 and the lid 22 are formed by dividing the protector 2 in the circumferential direction. Therefore, the main body 21 and the lid 22 are members having an arc-shaped cross section, and are arc-shaped in a cross section in a direction intersecting the extending direction of the electric wire W. The term "arc-shaped" here includes a substantially arc-shaped cross section. For example, the main body 21 and the lid 22 partially cover the outer peripheries of the bent pipe 41 and the straight pipe 42, respectively, and both the main body 21 and the lid 22 cover the entire outer peripheries of the bent pipe 41 and the straight pipe 42.

[0018] The lid portion 22 is provided so as to be openable and closable relative to the main body portion 21. One end of the lid portion 22 is pivotally supported by the main body portion 21 and rotates around that end, making it openable and closable relative to the main body portion 21. When the lid portion 22 is opened, the wire fastening device 1 can attach the protector 2 to the outer periphery of the bent pipe 41 and the straight pipe 42. The lid portion 22 has, for example, a first lid 221 and a second lid 222. The first lid 221 and the second lid 222 are provided at different positions in the axial direction X. For example, the first lid 221 is disposed at a position where the straight pipe 42 is provided, and the second lid 222 is disposed at a position where the bent pipe 41 is provided.

[0019] In Fig. 3, one end 221A of the first lid 221 in the width direction Y is pivotally supported by a first hinge 231 relative to the main body 21. Therefore, the first lid 221 rotates around the first hinge 231 to open and close relative to the main body 21. In Fig. 2, a first locking portion 241 is formed on the other end 221B of the first lid 221 in the width direction Y. The first locking portion 241 is engageable with a first locked portion 251 formed on the main body 21, and constitutes a locking mechanism for the first lid 221.

[0020] 4, the first locking portion 241 has a locking arm 241A extending circumferentially from the end portion 221B, and a protrusion 241B is formed at the tip of the locking arm 241A. The first locked portion 251 has, for example, a locking hole 251A formed therein through which the locking arm 241A can be inserted, and the locking arm 241A is inserted into this locking hole 251A. The protrusion 241B of the first locking portion 241 prevents the locking arm 241A from coming out of the locking hole 251A, thereby locking the first cover 221 so that it does not open.

[0021] 2 and 3, one end 222A of the second lid 222 in the width direction Y is pivotally supported by a second hinge 232 relative to the main body 21. Therefore, the second lid 222 rotates about the second hinge 232 to open and close relative to the main body 21. A second locking portion 242 is formed on the other end 222B of the second lid 222 in the width direction Y. The second locking portion 242 is engageable with a second locked portion 252 formed on the main body 21, and constitutes a locking mechanism for the second lid 222. The second locking portion 242 and the second locked portion 252 have the same structure as the first locking portion 241 and the first locked portion 251 described above, and lock the second lid 222 so that it does not open.

[0022] As shown in FIG. 5 , the annular portion 31 of the clamp 3 has a main body portion 311 and a lid portion 312. The main body portion 311 forms an arc-shaped inner circumferential surface 311A, and the lid portion 312 forms an arc-shaped inner circumferential surface 312A. The inner circumferential surfaces 311A and 312A form a circular inner circumferential surface 31A. The lid portion 312 rotates about a hinge 313 to open and close relative to the main body portion 311. That is, one end 312B of the lid portion 312 in the width direction Y is pivotally supported by the hinge 313 relative to the main body portion 311. Therefore, the lid portion 312 rotates about the hinge 313 to open and close relative to the main body portion 311. A locking portion 314 is formed on the other end 312C of the lid portion 312 in the width direction Y. The locking portion 314 is engageable with a locked portion 315 formed on the main body portion 311 , and constitutes a locking mechanism for the lid portion 312 .

[0023] The end 311B of the main body 311 where the locked portion 315 is formed is provided with the fixing portion 32 described above. The outer peripheral surface 312D of the lid 312 forms a flat portion 312E extending tangentially along the width direction Y. The flat portion 312E is a portion that forms a flat surface. The hole 32A of the fixing portion 32 opens in this flat portion 312E. Therefore, the electric wire fastening device 1 can be attached by closely contacting the flat portion 312E of the lid 312 with the attachment portion of the vehicle, and the electric wire fastening device 1 can be appropriately attached to the vehicle.

[0024] 2 and 3, the protector 2 is formed with a movement restricting portion 26. The movement restricting portion 26 is a portion that restricts the sliding movement of the clamp 3, and is formed on the outer periphery of the main body 21 and the first lid 221. The movement restricting portion 26 is a protrusion that protrudes from the outer periphery 2A of the protector 2, and two movement restricting portions 26 are formed spaced apart in the axial direction X. For example, the movement restricting portion 26 is formed in an annular shape that protrudes from the outer periphery 2A and extends in the circumferential direction. The outer periphery 2A between the two movement restricting portions 26, 26 is the mounting position of the clamp 3 and is the movement region R for the sliding movement of the clamp 3. The clamp 3 is mounted with the outer periphery of the outer periphery 2A between the two movement restricting portions 26, 26 covered by an annular portion 31.

[0025] The length of the movement region R between the movement restricting portions 26 is set to be longer than the width dimension in the axial direction X of the annular portion 31 of the clamp 3. Therefore, the clamp 3 is able to slide along the axial direction X between the two movement restricting portions 26. The length of the movement region R of the clamp 3 is set depending on, for example, dimensional errors of the bent pipe 41 and the straight pipe 42, and routing errors of the electric wire W. The outer diameter of the outer peripheral surface 2A between the movement restricting portions 26 is formed to be smaller than the inner diameter of the annular portion 31 of the clamp 3. Therefore, the clamp 3 is able to rotate while attached to the protector 2, as shown in FIG. 6 .

[0026] 3, first hinges 231, 231 that rotate first lid 221 are provided outside movement region R of clamp 3. For example, first hinge 231 is provided outside the region of outer peripheral surface 2A between movement restriction portions 26, 26 in axial direction X. By forming first hinge 231 in this manner, outer peripheral surface 2A on which clamp 3 is disposed can be made a smooth peripheral surface, thereby facilitating smooth rotational movement of clamp 3.

[0027] The protector 2 and the clamp 3 are formed by, for example, injection molding. This allows the protector 2 and the clamp 3 to be formed with high precision. This allows the protector 2 to be stably attached to the bent pipe 41 and the straight pipe 42, improving the attachability of the protector 2. In addition, the sliding and rotational movement of the clamp 3 relative to the protector 2 can be stably performed.

[0028] 2 and 5, the outer peripheral surface 2A between the movement restricting portions 26 and the inner peripheral surface 31A of the annular portion 31 of the clamp may be subjected to a surface treatment to increase the surface roughness. For example, the outer peripheral surface 2A and the inner peripheral surface 31A may be textured. In this case, the clamp 3 can slide and rotate relative to the protector 2, but excessive sliding is prevented. This makes it easier to maintain the position and posture of the clamp 3 in the electric wire fastening device 1, allowing for smooth operation of fastening the electric wire W.

[0029] As shown in FIG. 7 , the protector 2 is formed with a biting portion 27. The biting portion 27 is a portion that bites into a recessed portion on the outer periphery of the bent pipe 41 to hold the protector 2 relative to the bent pipe 41. The biting portion 27 is a protrusion that protrudes from the inner periphery of the main body 21 and is formed in an arc shape extending in the circumferential direction. For example, a plurality of biting portions 27 are formed, and are formed at intervals along the axial direction X. When the protector 2 is attached to the outer periphery of the bent pipe 41, the biting portions 27 enter the recessed portion 41B of the bent pipe 41 and restrict movement of the protector 2 in the axial direction X relative to the bent pipe 41.

[0030] In FIG. 1 , the protector 2 is formed with a binding portion 28. The binding portion 28 is a portion for attaching a binding member 5 that binds the protector 2 and the straight pipe 42. The binding member 5 is a band-like or string-like body that can bind the protector 2 and the straight pipe 42, and for example, a cable tie is used. The binding portion 28 is formed, for example, by extending the main body 21, to which the first lid 221 is attached, in the axial direction X, and has protrusions 28A, 28A that restrict movement of the binding member 5 in the axial direction X. The main body 21 on which the binding portion 28 is formed does not have a lid portion 22. Therefore, when the protector 2 is attached to the straight pipe 42, the binding member 5 is attached to the binding portion 28, thereby binding the straight pipe 42 and the protector 2 and supporting the protector 2 with respect to the straight pipe 42.

[0031] Next, the electric wire fastening device 1 and the electric wire fastening method for the wire harness WH according to this embodiment will be described.

[0032] 1, in fixing the electric wire W by the electric wire fastening device 1 and the wire harness WH, first, the bent pipe 41 and the straight pipe 42 are wrapped around the electric wire W. That is, the bent pipe 41 and the straight pipe 42 having lengths according to the layout of the vehicle are used, and the bent pipe 41 and the straight pipe 42 are attached to the outer periphery of the electric wire W.

[0033] Then, the protector 2 is attached to the bent pipe 41 and the straight pipe 42. The protector 2 is placed at a predetermined position relative to the main body 21 so as to cover the outer peripheries of the bent pipe 41 and the straight pipe 42 with the first lid 221 and the second lid 222 open. For example, the protector 2 is installed so that the first lid 221 is located on the outer periphery of the straight pipe 42 and the second lid 222 is located on the outer periphery of the bent pipe 41. Then, the first lid 221 and the second lid 222 are closed on the protector 2. At this time, a biting portion 27 is formed on the main body 21 of the protector 2, and the biting portion 27 fits into the recess 41B of the bent pipe 41. This restricts movement of the protector 2 in the axial direction X relative to the bent pipe 41.

[0034] Furthermore, the bundling member 5 is attached to the bundling portion 28 of the protector 2. That is, the bundling member 5 is arranged along the bundling portion 28 and wraps around the straight pipe 42 and the protector 2. This prevents the protector 2 from moving relative to the straight pipe 42. Furthermore, the straight pipe 42 is inserted into the protector 2 up to the inside of the mounting position of the clamp 3. Therefore, the straight pipe 42 is firmly held by the protector 2. This prevents the straight pipe 42 from bending after installation.

[0035] Then, clamp 3 is attached to protector 2. Clamp 3 is disposed between movement restricting portions 26, 26 of protector 2 with lid portion 312 open relative to main body portion 311. Then, clamp 3 is attached to the outer periphery between movement restricting portions 26, 26 with lid portion 312 closed, allowing sliding and rotational movement.

[0036] As shown in FIG. 8 , the electric wire fastening device 1 is attached to the bent pipe 41 and the straight pipe 42. In this case, a plurality of electric wire fastening devices 1 may be used in the wire harness WH depending on the layout of the vehicle. Also, a plurality of bent pipes 41 and straight pipes 42 may be used in the wire harness WH depending on the layout of the vehicle. In this way, the positions and orientations of the bent pipes 41 and straight pipes 42 vary depending on the layout of the vehicle, and the shape of the bent pipe 41 varies. In contrast, the electric wire fastening device 1 and the wire harness WH are attached to the outer peripheries of the bent pipes 41 and straight pipes 42 and can therefore be adapted to various vehicle layouts. That is, the electric wire fastening device 1 is attached to the bent pipes 41 and straight pipes 42 provided depending on the layout of the vehicle, and the clamp 3 can be slidably and rotatably moved relative to the protector 2 to fasten the electric wire W. Therefore, the electric wire fastening device 1 and the wire harness WH are highly versatile.

[0037] 1, an electric wire W is routed and fixed to a vehicle. That is, a bent pipe 41, a straight pipe 42, and an electric wire fastening device 1 are arranged along a route along which the electric wire W is to be routed to the vehicle, and the electric wire fastening device 1 is fixed to the vehicle body or the like by a clamp 3. The electric wire W is fixed to the vehicle by this fixing of the electric wire fastening device 1. The clamp 3 is fixed, for example, by inserting a stud bolt (not shown) provided on the vehicle into the hole 32A of the clamp 3. At this time, the clamp 3 is slidable along the axial direction X relative to the protector 2 and rotatable in the circumferential direction relative to the protector 2. That is, the clamp 3 is slidable along the axial direction X relative to the bent pipe 41 and the straight pipe 42 and rotatable in the circumferential direction. Therefore, the clamp 3 can be slidably moved along the axial direction X relative to the stud bolt protruding from the vehicle, thereby easily aligning the clamp 3 with the stud bolt protruding from the vehicle. Furthermore, the clamp 3 can be rotated with respect to the stud bolt protruding from the vehicle to adjust its posture or orientation. Therefore, the electric wire fastening device 1 and the wire harness WH can absorb dimensional errors of the bent pipe 41 and the straight pipe 42 or deviations in the arrangement positions of the bent pipe 41 and the straight pipe 42. In other words, the electric wire fastening device 1 and the wire harness WH can easily fix the clamp 3, and can smoothly perform the wiring and fixing work of the electric wire W.

[0038] As described above, in the electric wire fixing device 1 and the wire harness WH according to this embodiment, the clamp 3 is attached to the protector 2 attached to the bent pipe 41 and the straight pipe that accommodate the electric wire W so as to be able to slide and rotate, thereby facilitating the fixing of the clamp 3 to the vehicle and facilitating the wiring work of the electric wire W.

[0039] Furthermore, the electric wire fastening device 1 and the wire harness WH according to this embodiment are configured so that the protector 2 can be attached to the bent pipe 41 and the straight pipe that house the electric wire W, and therefore the electric wire W can be fixed using the electric wire fastening device 1 even in different vehicle layouts. Therefore, the electric wire fastening device 1 has high versatility in fixing the electric wire W.

[0040] Furthermore, in the electric wire fastening device 1 and the wire harness WH according to this embodiment, the protector 2 has a main body 21 and a lid 22 that are divided in the circumferential direction, and the lid 22 is pivotally supported on the main body 21 by a hinge so that it can be opened and closed. Therefore, in the electric wire fastening device 1, the lid 22 is the same part as the main body 21, and the number of parts can be reduced. Furthermore, the electric wire fastening device 1 and the wire harness WH can be easily attached to the electric wire W, and the ease of assembling the electric wire W can be improved.

[0041] Furthermore, in the electric wire fixing device 1 and the wire harness WH according to this embodiment, the hinge for rotating the cover portion 22 is provided outside the range of movement of the clamp 3, so that the outer peripheral surface 2A of the protector 2 can be made smooth at the mounting position of the clamp 3, thereby facilitating the rotational movement of the clamp 3.

[0042] Furthermore, the electric wire fastening device 1 and wire harness WH according to this embodiment use a bendable bent pipe 41 and a straight pipe 42 that is more rigid than the bent pipe as tubular members for accommodating the electric wires W, and the protector 2 is attached to the outer periphery of the bent pipe 41 and the straight pipe 42, and the straight pipe 42 is inserted into the protector 2 and held therein to the inside of the clamp 3. Therefore, the electric wire fastening device 1 can hold the straight pipe 42 with the protector 2, and can suppress bending of the straight pipe 42.

[0043] Next, a wire fastening device and a wire harness according to a second embodiment will be described.

[0044] As shown in Fig. 9, the electric wire fastening device 1A according to the second embodiment has a configuration substantially similar to that of the electric wire fastening device 1 according to the first embodiment described above, but differs from the electric wire fastening device 1 according to the first embodiment described above in that the main body 21 of the protector 2 forms an extending portion 211 along the shape of the bent tube 41. Furthermore, the electric wire fastening device 1A according to the second embodiment differs from the electric wire fastening device 1 according to the first embodiment having the first lid 221 and the second lid 222 in that it has a third lid 223, a fourth lid 224, and a fifth lid 225 in addition to the first lid 221 and the second lid 222. Furthermore, the electric wire fastening device 1A according to the second embodiment differs from the electric wire fastening device 1 according to the first embodiment having one clamp 3 in that it has two clamps 3. A wire harness WH according to the second embodiment is configured to include an electric wire W and the electric wire fastening device 1A.

[0045] The main body 21 of the protector 2 forms an extending portion 211. The extending portion 211 is a portion that supports the bent pipe 41, and is formed along the routing path of the electric wire W. The extending portion 211 has an arc-shaped cross section in a cross section that intersects with the extending direction of the electric wire W, and is provided so as to cover the lower part of the bent pipe 41. Therefore, the bent pipe 41 is arranged along the shape of the extending portion 211.

[0046] The extending portion 211 is provided with a third lid 223, a fourth lid 224, and a fifth lid 225. The third lid 223, the fourth lid 224, and the fifth lid 225 prevent the bent tube 41 housed in the extending portion 211 from being installed floating and prevent the bent tube 41 from moving up and down within the extending portion 211. The third lid 223, the fourth lid 224, and the fifth lid 225 are rotatable and lockable by a mechanism similar to that of the first lid 221 or the second lid 222. The fifth lid 225, like the first lid 221, may have a movement restricting portion 26 to allow the clamp 3 to slide and rotate. The extending portion 211 on which the third lid 223 and the fourth lid 224 are provided may have a bite portion 27. In this case, movement of the protector 2 in the axial direction X relative to the bent tube 41 can be restricted at the positions where the third lid 223 and the fourth lid 224 are provided.

[0047] The electric wire fastening device 1A and wire harness WH according to the second embodiment can achieve the same effects as the electric wire fastening device 1 and wire harness WH according to the first embodiment. For example, in the electric wire fastening device 1A and wire harness WH according to this embodiment, the clamp 3 is attached to the protector 2 attached to the bent pipe 41 and straight pipe that accommodate the electric wire W so as to be able to slide and rotate, which makes it easy to fasten the clamp 3 to the vehicle and smooth the installation work of the electric wire W. Furthermore, in the electric wire fastening device 1A and wire harness WH according to this embodiment, the cover portion 22 is pivotally supported by a hinge on the main body portion 21 so as to be openable and closable, and the cover portion 22 is made the same part as the main body portion 21, thereby reducing the number of parts. Furthermore, the electric wire fastening device 1A is easily attached to the electric wire W, which improves the ease of assembling the electric wire W. In addition, in the electric wire fastening device 1A and the wire harness WH according to this embodiment, the hinge for rotating the lid portion 22 is provided outside the movement range of the clamp 3, so that the outer peripheral surface 2A of the protector 2 can be made smooth, thereby facilitating smooth rotational movement of the clamp 3. Furthermore, in the electric wire fastening device 1A and the wire harness WH according to this embodiment, the straight pipe 42 is inserted into the protector 2 and held inside the clamp 3, so that bending of the straight pipe 42 can be suppressed.

[0048] Furthermore, the wire fixing device 1A and the wire harness WH according to the second embodiment have the same effects as the wire fixing device 1 and the wire harness WH according to the first embodiment described above, and are also capable of holding the bent tube 41 that is bent or curved by the extension portion 211 of the main body portion 21.

[0049] The electric wire fastening device 1A according to the second embodiment can also be used in combination with the electric wire fastening device 1 according to the first embodiment. For example, as shown in FIG. 10 , the electric wire fastening device 1A and the electric wire fastening device 1 are installed with a straight pipe 42 sandwiched between them. That is, the electric wire fastening device 1A is installed to support one end of the straight pipe 42, and the electric wire fastening device 1 is installed to support the other end of the straight pipe 42. As a result, the straight pipe 42 is firmly supported by the electric wire fastening device 1A and the electric wire fastening device 1 and is routed without bending. Furthermore, the bent pipe 41 is held by the extension portion 211 of the electric wire fastening device 1A and is properly routed along the routing path. The electric wire fastening device 1A and the electric wire fastening device 1 can be smoothly fixed to the vehicle because the clamp 3 can slide and rotate relative to the protector 2. Therefore, the electric wire W can be smoothly fixed and routed by the electric wire fastening device 1A and the electric wire fastening device 1.

[0050] The electric wire fastening device and the wire harness according to the present invention are not limited to the above-described embodiment, and various modifications are possible within the scope of the claims. The electric wire fastening device 1, 1A and the wire harness WH according to this embodiment may be configured by appropriately combining the components of the above-described embodiments and modified examples.

[0051] For example, the electric wire fastening devices 1, 1A and the wire harness WH according to the above-described embodiments have been described as being mounted on a vehicle, but they may also be used without being mounted on a vehicle.

[0052] Furthermore, in the electric wire fastening devices 1 and 1A according to the above-described embodiments, the outer peripheral surface 2A of the protector 2 has a circular cross section, and the inner peripheral surface 31A of the annular portion 31 of the clamp 3 has a circular cross section. However, the cross section of one of the outer peripheral surface 2A of the protector 2 and the inner peripheral surface 31A of the annular portion 31 of the clamp 3 may be circular, and the cross section of the other may be a shape other than circular. For example, the cross section of one of the outer peripheral surface 2A of the protector 2 and the inner peripheral surface 31A of the annular portion 31 of the clamp 3 may be circular, and the cross section of the other may be polygonal. Even in such an electric wire fastening device, the clamp 3 can be slidably moved and rotated relative to the protector 2.

[0053] Furthermore, the electric wire fastening devices 1, 1A according to the above-described embodiments are configured by attaching the protector 2 to the outer periphery of the bent pipe 41 and the straight pipe 42 and attaching the clamp 3 to the outer periphery of the protector 2. However, the clamp 3 may be attached directly to the outer periphery of the tubular member of the bent pipe 41 or the straight pipe 42. For example, the clamp 3 may be attached to the outer periphery of the tubular member to enable sliding and rotational movement relative to the tubular member, and two protectors 2 may be attached to the outer periphery of the tubular member, spaced apart from both ends of the clamp 3 and functioning as movement restrictors. Even with such an electric wire fastening device, the same effects as those of the above-described electric wire fastening device 1 can be obtained. That is, with this electric wire fastening device, the clamp 3 can be easily fixed to a vehicle, and the operation of routing the electric wire W can be performed smoothly. [Explanation of symbols]
