  Hereinafter, the harness clamp 10 which has the band lock structure part 12 which concerns on embodiment is demonstrated (refer FIG. 1, FIG. 2). The harness clamp 10 is a member for holding the wire harness 1 and fixing it to the fixed counterpart 90.

<Wire harness and fixed mating part>
For convenience of explanation, the wire harness 1 and the fixed mating part 90 to which the harness clamp 10 is applied will be described.

  The wire harness 1 is a wire harness that is routed in a vehicle, an electric device, or the like (explained here with an example of a vehicle), and is a wire having at least one electric wire. Here, the target wire harness 1 is composed of a single electric wire, a plurality of electric wires are bundled by tape winding or the like, an electric wire bundle is mounted with an exterior member such as a corrugated tube, etc. Is included.

  The wire harness 1 is routed to the vehicle along the routing route. At this time, the wire harness 1 is partially fixed to each part of the vehicle (fixed counterpart part 90) in the extending direction. The fixing counterpart 90 is, for example, a metal panel that constitutes the vehicle body of the vehicle, and is formed with a fixing hole 92 that penetrates in the thickness direction.

<Configuration of harness clamp>
The harness clamp 10 includes a band 20, a main body portion 30, a band locking portion 40, a fixing portion 50, a small protrusion 60 and a large protrusion 65. Schematically, in the harness clamp 10, the band 20 wound around the outer periphery of the wire harness 1 is maintained in a winding form by a band locking portion 40 provided in the main body portion 30, and is provided in the main body portion 30. The wire harness 1 is fixed to the vehicle by fixing the fixing portion 50 to the fixing hole 92 of the fixing counterpart 90. The harness clamp 10 is configured to be able to release the locked state of the band locking portion 40 with respect to the band 20 by operating the band locking portion 40. In addition, the band lock structure part 12 mentioned above points out the part provided with the band 20, the main-body part 30, and the band latching | locking part 40. FIG.

  Here, the harness clamp 10 is formed separately from the main body member in which the main body portion 30, the fixing portion 50, the band locking portion 40, the small protrusion 60, and the large protrusion 65 are integrally formed. It is configured by combining with the band 20. The main body member and the band 20 may be formed by injection molding of a synthetic resin material, respectively.

  The band 20 is a member wound around the outer periphery of the wire harness 1 (see FIG. 4). The band 20 is formed in a band shape in which a plurality of locked portions 22 are provided side by side in the longitudinal direction. More specifically, the band 20 is formed in a shape in which a plurality of concave locked portions 22 opened on one main surface are arranged at intervals in the longitudinal direction. The locked portion 22 is formed in a concave shape having a substantially rectangular parallelepiped internal space, and has locked surfaces that are substantially orthogonal to the longitudinal direction at both ends in the longitudinal direction of the band 20.

  The main body 30 is a part capable of supporting the wire harness 1 around which the band 20 is wound in a mounting shape. The main body 30 is formed in a substantially rectangular parallelepiped block shape, and can support the wire harness 1 along one main surface (hereinafter referred to as a support surface 38). The main body 30 is also a part that is inserted into the fixing hole 92 of the fixing counterpart 90. Hereinafter, the direction in which the main body 30 is inserted into the fixing hole 92 is referred to as an insertion direction S, and this insertion direction S is also used when describing the direction of the main body member itself. The support surface 38 is a rear end surface orthogonal to the insertion direction S of the main body 30. And the main-body part 30 is set to the external shape which can be inserted in the fixing hole 92 in the cross sectional view orthogonal to the insertion direction S with respect to the fixing hole 92 (refer FIG. 3). Preferably, the main body portion 30 is equal to or more than the interval between both side portions facing in one direction orthogonal to the penetration direction in the opening edge portion of the fixing hole portion 92 in one cross-sectional view orthogonal to the insertion direction S. It may be set to a slightly smaller dimension.

  More specifically, the main body 30 is formed with a pair of through-hole portions 32 that open at the support surface 38 and penetrate in one direction. The pair of through holes 32 are holes having a band insertion passage 34 through which the band 20 can be inserted. Here, the penetration direction of the pair of through-hole portions 32 is a direction along the insertion direction S. The pair of through-hole portions 32 are provided in parallel with an intermediate wall portion 35 formed flat along the penetration direction.

  The band insertion passage 34 is a portion near the intermediate wall portion 35 in the through-hole portion 32, and the band 20 is inserted along the intermediate wall portion 35. A band locking portion 40 to be described later is provided on the side of the band insertion passage 34 in the through-hole portion 32 (the inner wall side facing the intermediate wall portion 35).

  And the longitudinal direction intermediate part of the band 20 is made into a ring shape in the form of being wound around the outer peripheral part of the wire harness 1 on the support surface 38 side of the main body part 30, and the longitudinal direction both ends of the band 20 on the pair of through-hole parts 32. Each part is inserted (see FIG. 4). That is, the band 20 is set on the main body 30 in a posture in which both ends are exposed from the front side in the insertion direction S of the pair of through-hole portions 32.

  The band locking part 40 is a part that locks the band 20 and maintains the band 20 around the outer periphery of the wire harness 1. Here, the pair of band locking portions 40 is formed so as to be able to restrict movement of the band 20 inserted through the pair of through-hole portions 32 to the rear in the insertion direction S of the main body portion 30.

  The band locking part 40 is provided in a form protruding inside each through-hole part 32. The band locking portion 40 is formed so that its posture can be changed between the locking posture and the non-locking posture with the fulcrum portion 44 on the base end side as a base point. Here, the locking posture is a posture that can advance to the band insertion passage 34 and can selectively lock the plurality of locked portions 22 of the band 20 inserted through the through-hole portions 32. . The non-locking posture is a posture retracted from the band insertion passage 34.

  The band locking portion 40 has a locking claw 42, a fulcrum portion 44, and an unlocking pressing surface 48. More specifically, the band locking portion 40 includes a portion of the inner wall facing the intermediate wall portion 35 of the through-hole portion 32 to one through direction of the through-hole portion 32 (front of the insertion direction S) and the intermediate wall portion. It is formed in a shape that protrudes toward the 35 side. That is, the band locking portion 40 is supported by a fulcrum portion 44 that is continuous with the inner wall of the through-hole portion 32, and has a portion that extends forward from the fulcrum portion 44 in the insertion direction S.

  The locking claw 42 is a portion that is locked to the locked portion 22 of the band 20. The locking claw 42 is formed in a shape that protrudes toward the intermediate wall 35 at a portion of the band locking portion 40 that extends forward from the fulcrum portion 44 in the insertion direction S. The locking claw 42 has a locking surface that is substantially orthogonal to the insertion direction S and faces the front in the insertion direction S. Here, the locking claw 42 is formed in a substantially right-angled triangle shape in cross-section in which the protruding dimension gradually increases toward the front in the insertion direction S. That is, the locking claw 42 has an inclined surface that faces the insertion direction S rearward. Further, the locking claw 42 is set to a size that can be disposed inside the locked portion 22. In addition, here, the band locking portion 40 has two locking claws 42 spaced in the insertion direction S. The interval between the two locking claws 42 in the insertion direction S is set to be substantially the same as the interval between the plurality of locked portions 22.

  Then, the locking claw 42 advances into the band insertion passage 34 in a state where the band locking portion 40 is in the locking posture. In a state where the band 20 is inserted through the through-hole portion 32, the locking claw 42 is selectively fitted and locked to the plurality of locked portions 22. Further, the locking claw 42 is not locked to the locked portion 22 of the band 20 while being retracted from the band insertion passage 34 when the band locking portion 40 is in the non-locking posture (FIG. 7). reference). When the band 20 is moved from the state in which the band locking portion 40 is locked to the band 20 toward the front in the insertion direction S through the through-hole portion 32, the opening edge of the locked portion 22 is locked. In contact with the inclined surface of 42, the locking claw 42 changes its posture from the locking posture to the non-locking posture (see FIG. 8). Thereafter, the locking claws 42 are fitted into the other locked portions 22 and locked.

  Here, the band locking portion 40 is formed so as to be elastically deformable with the fulcrum portion 44 as a base point, so that the posture can be changed between the locking posture and the non-locking posture. The fulcrum part 44 is formed to be relatively thinner than a part on the front side in the insertion direction S. As a result, the band locking part 40 changes its posture with the fulcrum part 44 as a base point mainly by elastically deforming the fulcrum part 44. Needless to say, parts other than the fulcrum part 44 of the band locking part 40 can be elastically deformed simultaneously with the fulcrum part 44.

  The unlocking pressing surface 48 is a surface facing the insertion direction S (on the other side in the penetration direction of the through-hole portion 32) on the band insertion path 34 side from the fulcrum portion 44. Here, the unlocking pressing surface 48 is a surface on the distal end side of the unlocking protrusion 46. More preferably, the unlocking pressing surface 48 is inclined perpendicularly to the insertion direction S or rearward in the insertion direction S from the fulcrum part 44 side to the band insertion path 34 side when the band locking part 40 is in the locked posture. It is formed in the shape to do. As the most preferable form, it is considered that the unlocking pressing surface 48 is preferably formed in a shape orthogonal to the insertion direction S, and FIG.

  The unlocking protrusion 46 is formed in a shape protruding on the band insertion path 34 side from the fulcrum part 44 and on the rear side in the insertion direction S from the fulcrum part 44. The unlocking protrusion 46 protrudes with a gap from the inner wall of the through hole 32 that faces the intermediate wall 35. With this configuration, the band locking portion 40 can suppress the fulcrum portion 44 from being bent by excessively changing the posture in the direction in which the front end portion in the insertion direction S approaches the intermediate wall portion 35. In other words, the lock release protrusion 46 abuts against the inner wall of the through hole 32 that faces the intermediate wall 35, thereby restricting an excessive change in the posture of the band locking portion 40.

  Further, the unlocking projection 46 is formed in a shape that does not advance into the band insertion passage 34 even when the band locking portion 40 is changed from the locking posture to the non-locking posture. More specifically, the unlocking protrusion 46 is inclined in such a direction that a portion of the distal end side of the intermediate wall portion 35 is separated from the intermediate wall portion 35 toward the distal end side. Thereby, it is possible to suppress the band 20 from being caught by the unlocking protrusion 46 during the threading operation of the band 20 with respect to the through-hole portion 20, and the threading operation of the band 20 can be made smooth.

  Then, by pressing the unlocking pressing surface 48 from behind the insertion direction S, the band locking portion 40 changes its posture from the locking posture to the non-locking posture with the fulcrum portion 44 as a base point. Further, by releasing the pressed state, the band locking portion 40 tries to change the posture from the non-locking posture to the locking posture due to its own elasticity. At this time, the band locking portion 40 is in the locking posture when the band 20 is not inserted into the through-hole portion 32 or the locked portion 22 of the band 20 is positioned at the locking claw 42. If the portion between the locked portions 22 is located at the position of the locking claw 42, the portion is brought into contact with the portion and maintained in the unlocked posture.

  The fixing part 50 is a part that fixes the main body part 30 to the fixing counterpart part 90. The fixing part 50 has a locking part 52 and a pressing part 56 (see FIG. 1).

  The locking part 52 is a part that locks the peripheral edge of the fixing hole 92 from the front side in the insertion direction S of the main body 30. The locking portion 52 is formed in a shape protruding from the outer peripheral surface of the main body portion 30 (here, the front end portion in the insertion direction S) to the outer peripheral side, and gradually extends from the front side to the rear side in the insertion direction S of the main body portion 30. The overhang dimension is large. And the latching | locking part 52 is formed so that a front end side part may be made into a free end and to be elastically deformed toward the inner peripheral side. A locking surface directed toward the rear in the insertion direction S is provided at the distal end portion of the locking portion 52. Here, a plurality of locking surfaces are provided in stages in the insertion direction S of the main body 30. That is, the locking surface that locks to the peripheral edge varies depending on the thickness of the panel that is the fixed counterpart 90. Further, here, the locking portions 52 are provided at two opposing positions in the outer peripheral portion of the main body portion 30.

  The locking portion 52 is elastically deformed to the inner peripheral side as the main body portion 30 is inserted into the fixing hole 92, and returns to the form before elastic deformation when the locking surface exceeds the fixing hole 92. To do. Accordingly, the locking portion 52 is in a state where the locking surface is locked from the front side in the insertion direction S with respect to the peripheral portion of the fixing hole 92.

  The presser portion 56 is a portion that is engaged with the peripheral edge portion of the fixing hole portion 92 from the rear side in the insertion direction S of the main body portion 30 (see FIG. 4). The presser portion 56 is formed in a hook shape projecting from the outer peripheral portion of the main body portion 30 (here, the rear end portion in the insertion direction S) to the outer peripheral side. Here, the presser portion 56 is formed in a substantially elliptic shape (specifically, a shape in which a pair of arc-shaped portions are connected by a pair of linear portions).

  Further, the outer peripheral side portion of the presser portion 56 is formed in a shape toward the front side in the insertion direction S of the main body portion 30 as it approaches the outer peripheral edge portion. The outer peripheral side portion of the presser portion 56 is elastically deformable (disc spring shape) toward the rear in the insertion direction S. The outer peripheral edge portion of the presser portion 56 is provided with an interval smaller than the thickness dimension of the fixed mating portion 90 with respect to each locking surface of the locking portion 52.

  Further, the inner peripheral side portion of the presser portion 56 is equal to or larger than the thickness dimension of the panel which is the fixed mating portion 90 with respect to each locking surface of the locking portion 52 in the insertion direction S (here, (Slightly larger) are provided at intervals.

  The presser portion 56 is elastically deformed toward the rear in the insertion direction S as the main body 30 is inserted into the fixing hole 92. As a result, in a state in which the locking portion 52 is locked from the front side in the insertion direction S with respect to the peripheral edge portion of the fixing hole 92, the presser portion 56 is behind the peripheral edge portion of the fixing hole 92 in the insertion direction S. Lock from the side. That is, the locking portion 52 is pressed against the peripheral portion of the fixing hole 92 by the force of pressing the peripheral portion of the fixing hole 92 in an attempt to return to the shape before the elastic deformation of the presser portion 56, and the fixing hole portion 92 is maintained in a state sandwiched between the locking portion 52 and the pressing portion 56 in the insertion direction S.

  The small protrusion 60 and the large protrusion 65 are parts for suppressing the harness clamp 10 from rotating or extending around the central axis with respect to the wire harness 1 to be fixed.

  The small protrusion 60 is a part that mainly suppresses the rotation and movement of the harness clamp 10 relative to the small-diameter wire harness 1. The small protrusion 60 is formed in a shape protruding rearward from the support surface 38 of the main body 30 in the insertion direction S. The small protrusions 60 are provided on the support surface 38 of the main body 30 at positions on both sides of the band 20 (the pair of through-hole portions 32) in the routing direction R in which the wire harness 1 is routed. The small protrusions 60 are provided at positions on both sides with respect to the center in the routing direction R. That is, four small protrusions 60 are provided here.

  In the routing direction R, the small protrusions 60 are provided at intervals smaller than the diameter of the smallest wire harness 1 to be fixed (here, slightly smaller). Moreover, the small protrusion 60 is set to a protruding dimension that can bite into the outer peripheral surface of the small-diameter wire harness 1. Here, the small protrusion 60 is formed in a cylindrical shape having a hemispherical shape at the tip.

  The large protrusion 65 is a portion that suppresses the rotation and movement of the harness clamp 10 relative to the large-diameter wire harness 1. The large protrusion 65 is formed in a shape protruding rearward from the support surface 38 of the main body 30 in the insertion direction S. The large protrusion 65 is located outside the small protrusion 60 with respect to the center in the direction orthogonal to the routing direction R on the support surface 38 of the main body 30, and the band 20 ( It is provided in the position of the both sides of a pair of through-hole part 32). The large protrusions 65 are provided at positions on both sides of the band 20 in the direction along the routing direction R. In other words, four large protrusions 65 are also provided here.

  More specifically, the large protrusions 65 are provided at intervals smaller than (in this case, slightly smaller) the diameter (reference dimension (for example, 5 mm)) of the smallest wire harness 1 in the routing direction R. It has been. The large protrusion 65 is formed in a shape that protrudes larger than the small protrusion 60. More specifically, the large protrusion 65 is set to a size that can bite into the outer peripheral surface of the large-diameter wire harness 1. Here, the large protrusion 65 is formed flat along the wiring direction R of the wire harness 1, and the tip is formed in an arc shape when viewed from the wiring direction R and its orthogonal direction. That is, the tops of the small protrusions 60 and the large protrusions 65 are formed with curved surfaces to prevent damage to the wire harness 1.

<Attaching the harness clamp>
A method for attaching the harness clamp 10 will be described.

  First, the wire harness 1 is disposed on the support surface 38 along the routing direction R. At this time, the wire harness 1 may be disposed on the support surface 38 so that the central axis is located at substantially the center in the direction orthogonal to the routing direction R. However, the wire harness 1 may be disposed on the support surface 38 after passing the band 20 through the one through-hole portion 32. 6 to 8, the wire harness 1 is omitted.

  Next, the intermediate portion in the longitudinal direction of the band 20 is wound around the outer peripheral portion of the wire harness 1 on the support surface 38, and both end portions of the band 20 are inserted into the pair of through-hole portions 32. Here, the band 20 is inserted from the front in the insertion direction S into one through-hole portion 32 and pulled out from the rear of the main body 30, and the middle portion in the longitudinal direction of the band 20 is wound around the outer periphery of the wire harness 1 To the other through hole 32.

  Here, in order to reduce the material used for the band 20, a continuous band material in the longitudinal direction is continuously supplied from a supply source stored in a roll shape.

  That is, some wire harnesses 1 to be fixed have different sizes (diameters). For this reason, when the band 20 prepared by cutting to the same length is used, the band 20 is left over when the harness clamp 10 is applied to the small-sized wire harness 1. The extra length of the band 20 is usually cut off. Therefore, the inventor of the present application continuously obtains a band 20 having a required length corresponding to the size of the wire harness 1 by continuously supplying the band material, pulling out the band material by a required length, and cutting it on the supply side. Thought.

  More specifically, first, the continuous band 20 (band material) is inserted into one through-hole portion 32 from the front in the insertion direction S. At this time, since the band locking portion 40 is in the locking posture, it is retracted from the band insertion path 34. That is, the lock release pressing surface 48 is pressed toward the front in the insertion direction S to change the posture of the band locking portion 40 to the non-locking posture. This operation may be performed using a pressing jig 80 as shown in FIG. The pressing tool 80 has a flat pressing portion capable of pressing the unlocking pressing surface 48 by opening the band insertion passage 34 (without entering the band insertion passage 34) with respect to the through-hole portion 32. It is good that it has a shape.

  The band 20 is pulled out from the rear side in the insertion direction S of the one through-hole portion 32 in a state where the posture of the band locking portion 40 is changed to the non-locking posture. Then, the band 20 is wound around the outer peripheral portion of the wire harness 1 while being pulled out from the one through-hole portion 32. Here, the lock release pressing surface 48 is still pressed by the pressing jig 80 to keep the band locking portion 40 in the non-locking posture (see FIG. 8). However, the band 20 may be pulled out from the one through-hole portion 32 to a required length or more, and the pressing force against the unlocking pressing surface 48 may be released.

  Further, the band 20 having the outer peripheral portion of the wire harness 1 made one turn is inserted into the other through-hole portion 32 from the rear in the insertion direction S (see FIG. 8). At this time, the end portion of the band 20 or the locked surface of the locked portion 22 abuts on the inclined surface of the locking claw 42, and the posture of the band locking portion 40 is changed from the locked posture to the non-locked posture. The Further, when the locked portion 22 moves to the position of the locking claw 42, the band locking portion 40 moves into the band insertion path 34 because the locking claw 42 is fitted in the locked portion 22. Change the position to the locked position.

  The band 20 is inserted into the other through-hole portion 32 until the locking claw 42 (both in this case) is fitted and locked into the locked portion 22, and then the band 20 is tightened. Here, the band 20 is inserted until it is exposed from the front in the insertion direction S of the other through-hole portion 32 (it does not need to extend). In this state, at least one of the ends of the band 20 is pulled forward in the insertion direction S, and the middle portion in the longitudinal direction of the band 20 tightens and holds the wire harness 1. Here, if only the band 20 extending from the front in the insertion direction S of one through-hole portion 32 is pulled out and tightened, the extra length of the band material can be further reduced. Here, when pulling the end portion of the band 20, the band 20 is drawn into the pair of through-hole portions 32 while contacting the rounded portion 36 at the rear end portion in the insertion direction S of the main body portion 30 (see FIG. 4). ). For this reason, the band 20 is not bent but is curved along the curved surface of the rounded portion 36 partially or entirely at the rear end portion in the insertion direction S of the main body portion 30.

  Here, since the unlocking pressing surface 48 is not pressed, the band locking portion 40 is locked to the band 20 and restricts the movement of the band 20 in the insertion direction S rearward. Thereby, the fastening state of the wire harness 1 by the band 20 can be maintained. Thereafter, the band 20 extending from the front in the insertion direction S from one through-hole portion 32 is cut.

  Next, the harness clamp 10 holding the wire harness 1 is fixed to the fixing counterpart 90. More specifically, the main body 30 is fixed to the fixing counterpart 90 by inserting the main body 30 into the fixing hole 92 along the insertion direction S. That is, the locking part 52 and the pressing part 56 are locked from the front and back in the insertion direction S with respect to the peripheral edge of the fixing hole 92, respectively. As a result, the portion of the wire harness 1 to which the harness clamp 10 is attached is fixed to the predetermined fixing counterpart 90.

  According to the harness clamp 10 (band lock structure portion 12) according to the above configuration, one through direction of the through-hole portion 32 from the inner wall facing the intermediate wall portion 35 inside the pair of through-hole portions 32 formed in the main body portion 30. Locking that can be selectively locked to the plurality of locked portions 22 of the band 20 that protrudes (forward in the insertion direction S), advances into the band insertion passage 34, and is inserted through the through-hole portions 32. Between the posture and the non-locking posture retracted from the band insertion passage 34, the posture can be changed with the fulcrum portion 44 on the base end side as a base point. A band locking portion 40 having an unlocking pressing surface 48 facing the other side in the direction (rear side in the insertion direction S) is provided. For this reason, by pressing the unlocking pressing surface 48 toward one side of the through-hole portion 34 in the penetrating direction, the posture of the band locking portion 40 in the locking posture is changed from the fulcrum portion 44 to the non-locking posture. It is possible to release the lock on the band 20 with a simple configuration.

  In addition, from the viewpoint of manufacturing the harness clamp 10 or the band lock structure 12, it is possible to perform unlocking only by forming the unlocking pressing surface 48. The configuration can be realized by a simple mold surface shape of the mold.

  And the lock | rock with respect to the band 20 of the band latching | locking part 40 can be cancelled | released only by pushing the pressing surface 48 for unlocking toward the insertion direction S front.

  In addition, the band locking part 40 is spaced from the fulcrum part 44 on the band insertion path 34 side with respect to the inner wall of the through-hole part 32, and the lock protrudes from the fulcrum part 44 to the other side in the penetration direction of the through-hole part 32. According to the configuration having the release protrusion 46 and the lock release pressing surface 48 set on the front end surface of the lock release protrusion 46, the lock provided at a position further away from the fulcrum part 44 Since the release pressing surface 48 is pressed, the posture of the band locking portion 40 can be changed with a smaller force when the unlocking pressing surface 48 is pressed.

  Further, according to the configuration in which the unlocking pressing surface 48 is formed in a shape orthogonal to the penetrating direction of the through-hole portion 32, the pressing jig 80 is pressed when the unlocking pressing surface 48 is pressed. Thus, the unlocking pressing surface 48 can be more reliably pressed and the shifting of the unlocking pressing surface 48 can be more reliably performed.

  In addition, according to the configuration in which the unlocking pressing surface 48 is formed in a shape that is inclined from the fulcrum portion 44 side toward the band insertion passage 34 side toward the other side in the penetration direction with respect to the penetration direction of the through hole portion 32. When the unlocking pressing surface 48 is pressed, the displacement of the pressing jig 80 and the like toward the intermediate wall 35 can be suppressed, and the unlocking pressing surface 48 can be pressed more reliably.

  The unlocking pressing surface 48 is the tip surface of the unlocking protrusion 46 and has been described as an example orthogonal to the insertion direction S, but is not limited thereto. That is, the unlocking pressing surface may be a surface that can be pressed from the rear in the insertion direction S in order to change the posture of the band locking portion 40, and is an inclined surface other than orthogonal to the insertion direction S. Also good. That is, to face the other through direction of the through-hole portion 32 is not limited to a surface that is perpendicular to the penetrating direction and faces the other, but includes an inclined surface other than the perpendicular direction. Further, the unlocking pressing surface 48 is not limited to the tip surface of the unlocking projection 46, and the unlocking projection 46 is omitted, and the band insertion portion 44 of the band locking portion 40 is inserted into the band. It may be a base end face located on the passage 34 side.

  Further, the small protrusions 60 and the large protrusions 65 may be omitted, or a number other than four may be provided.

  Further, the configuration of the harness clamp 10 including the band lock structure portion 12 has been described so far, but the band lock structure portion 12 may be used alone. That is, the band lock structure 12 can be used alone for the purpose of binding and holding a plurality of electric wires or the like constituting the wire harness 1. In FIG. 9, the example which uses the band lock structure part 12 as a binding member of the wire harness 1 is shown. In addition, in FIG. 9, although the example provided with the small protrusion 60 and the large protrusion 65 is shown, you may abbreviate | omit. That is, the band lock structure 12 can be used as the harness clamp 10 by providing the fixing portion 50.

  Even when the band lock structure 12 is used alone, the band 20 can be unlocked with a simple configuration provided with the unlocking pressing surface 48, and the band locking portion 40 can be released from the one through-hole portion 32. The band 20 can be easily passed from the front end side. Thereby, the band material can be continuously supplied and the remainder of the band material can be suppressed.

  Further, in the harness clamp having the band lock structure portion 12, a fixing structure different from the fixing portion 50 having the locking portion 52 and the pressing portion 56 may be adopted. For example, a fixing structure that has an adhesive surface and can be attached to the fixed mating part 90, a fixing structure that can be screwed to the fixing mating part 90, and the like can be employed.

  As mentioned above, although the band lock structure part 12 and the harness clamp 10 were demonstrated in detail, above-described description is an illustration in all the phases, Comprising: This invention is not limited to it. The various modifications described above can be applied in combination as long as they do not contradict each other. And it is understood that the countless modification which is not illustrated can be assumed without deviating from the scope of the present invention.
