<Embodiment>
First, the clamp 100 according to the embodiment and the clamped electric wire 110 including the clamp 100 and the electric wire portion 9 will be described with reference to FIGS. The clamp 100 fixes the electric wire portion 9 to the mating member 8. Note that the clamp 100 may be referred to as a clamp. The clamp 100 fixes the electric wire part 9 which is an electric wire or an electric wire bundle to the other party member to be fixed. The electric wire part 9 includes one electric wire or a plurality of electric wires (electric wire bundle).

  The clamp 100 includes a band part 1, a band locking part 2, a support part 3, and a counterpart fixing part 4. And the support part 3 contains the support protrusion part 31 which can support the electric wire part 9. As shown in FIG.

  FIG. 1 is a perspective view of the clamp 100 as viewed from the support protrusion 31 side of the support 3. FIG. 2 is a perspective view of the clamp 100 as viewed from the counterpart fixing portion 4 side. FIG. 3 is a plan view of the clamp 100 as viewed from the support protrusion 31 side. FIG. 4 is a plan view of the clamp 100 as viewed from the counterpart fixing portion 4 side. FIG. 5 is a front view of the clamp 100. FIG. 6 is a partially cutaway front view of the clamp 100. FIG. 7 is a side view of the clamp 100.

  8 and 10 are front views of the clamped electric wire 110. In FIG. 8, the case where the electric wire part 9 in the electric wire 110 with a clamp is a comparatively small diameter is drawn. On the other hand, in FIG. 10, the case where the electric wire part 9 in the electric wire 110 with a clamp is a comparatively large diameter is drawn. 8 and 10, the band portion 1 is drawn with a virtual line (two-dot chain line). FIG. 9 is a plan view of the electric wire with clamp 110 of FIG. 8 as viewed from the support protrusion 31 side. 5, 9, and 12, the band portion 1 is omitted for convenience.

  First, the counterpart member 8 will be described. The counterpart member 8 is a fixing destination of the clamp 100. In the present embodiment, the mating member 8 is a plate-like member as shown in FIG. It is conceivable that the counterpart member 8 is, for example, a metal panel constituting the vehicle body. In FIG. 7, the counterpart member 8 is indicated by a virtual line (two-dot chain line).

  Further, here, the counterpart member 8 is formed with a hole (fixing hole 81) for fixing the clamp 100. As shown in FIGS. 8 and 9, the fixing hole 81 is a through-hole penetrating from one main surface side of the counterpart member 8 to the other main surface side.

  Next, the clamp 100 will be described. As described above, the clamp 100 includes the band portion 1, the band locking portion 2, the support portion 3 including the support protruding portion 31, and the counterpart fixing portion 4. The clamp 100 is formed, for example, by injection molding a synthetic resin material. Here, the clamp 100 is integrally formed with the band portion 1, the band locking portion 2, the support portion 3, and the counterpart fixing portion 4.

  In the present embodiment, as shown in FIG. 1, the support portion 3 is formed in a dish shape. The support part 3 includes a support protrusion 31. In the present embodiment, the support portion 3 further includes a body portion 32. In the present embodiment, the support portion 3 is formed with a through hole 33 through which the band portion 1 can be inserted.

  In the clamp 100, the support protrusion 31 is a portion that can support the electric wire portion 9. Here, the support protrusion 31 is formed so as to protrude toward the electric wire portion 9 (opposite to the counterpart fixing portion 4). The support protrusion 31 includes a first protrusion 311 and a positioning protrusion 99. In the present embodiment, the support protrusion 31 further includes a second protrusion 312.

  First, the trunk | drum 32 of the support part 3 is demonstrated. In this embodiment, the trunk | drum 32 surrounds the support protrusion part 31, and is formed so that elastic deformation is possible. Here, when the body portion 32 is elastically deformed, the support portion 3 functions as a disc spring when the clamp 100 is locked in the fixing hole 81.

  Here, it can be said that the support protruding portion 31 is a portion that is surrounded by the body portion 32 and is relatively difficult to deform. Therefore, in the present embodiment, the support protrusion 31 is a portion (region) that is relatively difficult to deform and is surrounded by the body 32 that functions as a disc spring. For this reason, it is conceivable that the support protrusion 31 is a portion formed relatively thicker than the body portion 32. On the other hand, the trunk portion 32 is a portion that is formed around the support protrusion 31 and is relatively easily deformed. Therefore, it is conceivable that the body 32 is formed to be relatively thinner than the support protrusion 31.

  In this embodiment, the trunk | drum 32 is formed so that it may extend from the support protrusion part 31 in the aspect expanded toward an outer side. Moreover, the trunk | drum 32 contains the surrounding surface which hangs down to the other party fixing | fixed part 4 side as it goes outside from the support protrusion part 31. As shown in FIG. The trunk | drum 32 contains at least one part of the surrounding surface from which the vertex part of the cone was excised, for example. In addition, the outer edge of the trunk | drum 32 is set so that it may be located in the outer side of the fixing hole 81. FIG. The body 32 is bent so that the diameter of the body 100 is increased when the clamp 100 is locked in the fixing hole 81 of the counterpart member 8, so that the fixed state of the counterpart member 8 and the clamp 100 is improved.

  In the present embodiment, the body portion 32 is provided with a recess 321 and a rib 322. The recessed portion 321 is formed so that the outer edge is recessed toward the inner peripheral side in at least a part of the body portion 32. Here, the recess 321 is provided adjacent to the support protrusion 31. As shown in FIGS. 1 and 3, two recesses 321 are formed. Here, the support protrusion 31 exists between the two recesses 321 in a direction intersecting with the extending direction of the wire portion 9 (hereinafter referred to as the width direction of the wire portion 9). That is, in this embodiment, since the two recessed parts 321 are formed, the trunk | drum 32 is formed in the aspect divided | segmented into two by the intermediate part being separated by the recessed part 321. FIG.

  By forming the recessed part 321 in the trunk | drum 32, it becomes easy to bend so that the trunk | drum 32 may expand in diameter, and the force which concerns on the insertion becomes small. However, when the recessed part 321 is formed in the trunk | drum 32, while the trunk | drum 32 will turn easily from the inner peripheral part of the recessed part 321 among the trunk | drums 32, it will be easy to bend in the state where it turned up. And when the trunk | drum 32 has turned up, the area which contacts the other party member 8 among the trunk | drums 32 may reduce, and it may lead to the shakiness etc. of the clamp 100. FIG. In this embodiment, ribs 322 are provided on the body part 32 in order to suppress the turning of the body part 32.

  The rib 322 is provided on the inner peripheral edge of the recess 321 in the body portion 32. Here, the rib 322 is provided on the opposite side of the body portion 32 from the side on which the counterpart fixing portion 4 extends, that is, the side on which the support protrusion 31 protrudes. Thereby, it can suppress that the rib 322 contacts the other party member 8. FIG.

  Further, as shown in FIG. 3, since the concave portion 321 is provided in a square shape in plan view, four ribs 322 are provided, and are provided on the entire inner peripheral edge of the concave portion 321. However, it is conceivable that the rib 322 is provided on at least a part of the inner peripheral edge of the recess 321. Preferably, the rib 322 is provided on a portion of the body portion 32 that is easily turned over. In addition, the part which is easy to turn of the trunk | drum 32 is a part corresponded to the outer periphery of the trunk | drum 32, its vicinity, and the inner peripheral part of the recessed part 321, for example.

  Further, as shown in FIG. 3, since the concave portion 321 is provided in a square shape in plan view, the rib 322 is provided linearly along the contour of the concave portion 321. Moreover, the thickness dimension and width dimension of the rib 322 should just be set suitably. For example, the larger the thickness and width dimensions of the ribs 322, the more difficult the body part 32 is turned over, and the easier it is to return to the original state from the turned-up state. Moreover, the increase in insertion force can be suppressed, so that the thickness dimension and width dimension of the rib 322 are small.

  In the present embodiment, the rib 322 is provided on the inner peripheral edge portion of the recess 321 in the body portion 32, whereby the rigidity is increased and the body portion 32 can be prevented from being turned up. In addition, even when the body part 32 is turned over, it is easy to return to the state before the body part is turned over, and it is possible to suppress the state where the body part 32 is turned up and to suppress wrinkles in the turned up state. Can do.

  In addition, a hole 323 that penetrates from one main surface side of the body portion 32 to the other main surface side is formed in the body portion 32. The hole 323 is, for example, a hole for punching out the clamp 100. In the present embodiment, the hole 323 is formed in each of the body portions 32 formed in such a manner that an intermediate portion is separated by a concave portion 321 and divided into two. That is, two holes 323 are formed in the body portion 32 of the support portion 3. The holes 323 are formed on both sides of the support protrusion 31 in the extending direction of the electric wire portion 9.

  Next, the counterpart fixing part 4 in the clamp 100 will be described. The counterpart fixing portion 4 is formed to protrude from the support portion 3 to the opposite side of the electric wire portion 9. In the clamp 100, the counterpart fixing portion 4 is a portion that can be fixed to the counterpart member 8.

  In the present embodiment, the counterpart fixing portion 4 includes a shaft portion 44 and a locking portion 45. Here, as shown in FIGS. 5 and 7, the shaft portion 44 is formed to extend toward the opposite side with respect to the support protrusion 31 side of the support portion 3. The shaft portion 44 is a portion that is inserted into the fixing hole 81 of the counterpart member 8.

  In the present embodiment, the through hole 33 formed in the support portion 3 penetrates the shaft portion 44. That is, here, the through hole 33 is formed from the side of the support portion 3 where the electric wire portion 9 is supported toward the distal end side of the shaft portion 44. Therefore, in the clamp 100, the band portion 1 is inserted from the one opening 331 side on the support portion 3 side in the through hole 33 toward the other opening 332 side on the distal end side of the shaft portion 44.

  Moreover, in this embodiment, the latching | locking part 45 is extended and formed toward the support part 3 side from the front-end | tip part of the axial part 44, as FIG. 7 shows. Here, a pair of locking portions 45 are formed so as to extend from the distal end portion of the shaft portion 44 toward the support portion 3 side.

  In the clamp 100, the locking portion 45 is a portion that is caught by the inner peripheral edge portion of the fixing hole 81 after being inserted into the fixing hole 81. The clamp 100 is locked to the counterpart member 8 when the locking portion 45 is hooked on the inner peripheral edge of the fixing hole 81.

  Further, in the present embodiment, the pair of locking portions 45 are formed to be elastically deformable so that the width thereof is set larger than the width of the fixing hole 81 and the width is smaller than the width of the fixing hole 81. Has been. The locking part 45 can be inserted into and passed through the fixing hole 81 by elastically deforming the locking part 45 so that the width of the locking part 45 is smaller than the width of the fixing hole 81. And the thing which the latching | locking part 45 elastically deformed after passing through the fixing hole 81 returns, and the width | variety becomes larger than the width | variety of the fixing hole 81, and the front-end | tip vicinity of the latching | locking part 45 is near the fixing hole 81. The clamp 100 is caught in the inner peripheral edge, and the clamp 100 is locked in the fixing hole 81.

  In the present embodiment, a step 452 is provided at the tip of the locking portion 45, and the inner peripheral edge of the fixing hole 81 is set to be hooked on the step 452. In the present embodiment, as shown in FIG. 7, the stepped portion 452 is formed in two steps. However, a case where the level difference of the level difference part 452 is one level, or a case where the level difference is three or more levels can be considered. Note that the greater the number of steps in the step 452, the greater the range of the thickness of the counterpart member 8 that can be handled by one type of clamp 100.

  The clamp 100 is attached to the counterpart member 8 as follows, for example. Here, the thickness of the inner peripheral edge portion of the fixing hole 81 of the counterpart member 8 is larger than the distance between the stepped portion 452 along the extending direction of the shaft portion 44 of the clamp 100 and the body portion 32 of the support portion 3. It will be described as large.

  First, the clamp 100 is inserted by the operator so that the shaft portion 44 of the clamp 100 is inserted into the fixing hole 81 of the counterpart member 8 in a state where the counterpart member 8 is positioned on the shaft portion 44 side of the clamp 100. It approaches the counterpart member 8. Eventually, the outer surface of the locking portion 45 comes into contact with the inner peripheral edge of the fixing hole 81, and reaction force from the inner peripheral edge of the fixing hole 81 starts to be applied to the operator. When the clamp 100 is further moved against the reaction force, the locking portion 45 starts to be elastically deformed, and the clamp 100 is gradually inserted into the fixing hole 81.

  At this time, since the thickness of the counterpart member 8 is larger than the distance between the stepped portion 452 along the extending direction of the shaft portion 44 and the body portion 32 of the support portion 3, the locking portion 45 passes through the fixing hole 81. During the process, the body 32 starts to contact the inner peripheral edge of the fixing hole 81. As a result, the body portion 32 begins to be elastically deformed so as to bend and expand in diameter, and the reaction force from the portion of the inner peripheral edge of the fixing hole 81 that is in contact with the body portion 32 is also applied. When the operator further inserts the clamp 100 from this state, the base side portion of the stepped portion 452 of the locking portion 45 passes through the fixing hole 81 and is fixed between the stepped portion 452 and the trunk portion 32. When the inner peripheral edge portion of the hole 81 is sandwiched, the counterpart fixing portion 4 of the clamp 100 is engaged with the fixing hole 81.

  Next, the band unit 1 will be described. The band portion 1 is formed so as to be able to be wound around the electric wire portion 9 supported by the support protrusion 31. Here, the band part 1 is formed in a narrow strip shape. In the present embodiment, one end of the band portion 1 is formed continuously to the support portion 3.

  In the present embodiment, the band portion 1 includes a long portion 14 including a portion covering the periphery of the hinge portion 11 and the electric wire portion 9 and a locking recess 12. Here, the long portion 14 has a recessed central region, and the locking recess 12 is provided in a recessed portion of the long portion 14. In addition, as FIG. 1 shows, a pair of wall part 15 higher than the projection part which comprises the latching recessed part 12 is formed in the both sides of the center area | region in the elongate part 14. As shown in FIG. Of course, the case where the band portion 1 is substantially flat, that is, the case where the pair of wall portions 15 are not formed, is also conceivable.

  In this embodiment, the hinge part 11 is formed in the part connected to the support part 3 in the band part 1. The hinge portion 11 is a portion that can be deformed with a connection portion with the support portion 3 as a base point so as to cover the electric wire portion 9. With the hinge portion 11, the band portion 1 can be easily wound around the electric wire portion 9.

  Further, as shown in FIG. 1, a plurality of locking recesses 12 are formed on the main surface on one side of the long portion 14 of the band portion 1 so as to be aligned along the longitudinal direction of the band portion 1. Yes. In addition, the main surface on one side of the long portion 14 of the band portion 1 means a main surface facing the wire portion 9 side in a state where the band portion 1 is wound around the wire portion 9.

  Further, as shown in FIG. 3, in the present embodiment, the end portion 13 on the opposite side of the band portion 1 with respect to the hinge portion 11 side is formed in a flat shape. In the clamp 100, the band portion 1 is passed from the end portion 13 to the through hole 33, and the plurality of locking recesses 12 are engaged with the band locking portion 2 described later, whereby the band portion 1 is surrounded by the wire portion 9. The state wound around is maintained.

  Next, the band locking part 2 will be described. The band locking portion 2 maintains the state in which the wire portion 9 is supported by the support protrusion 31 by maintaining the state in which the band portion 1 is wound around the wire portion 9. Here, the band locking portion 2 is formed inside the through hole 33 and is formed to extend from a portion on the one opening 331 side on the side where the band portion 1 is inserted toward the other opening 332 side on the opposite side. ing.

  More specifically, as shown in FIG. 6, the base side portion (base portion 29) of the band locking portion 2 is a portion near the one opening 331 of the through-hole 33, and the one opening 331 and the other portion. It is provided in a portion between the opening 332. As will be described later, a positioning convex portion 99 is provided between the root portion 29 and the one opening 331. Here, as shown in FIG. 6, the band engaging portion 2 has a root portion 29 connected to a surface of the inner surface forming the through hole 33 on the side where the hinge portion 11 of the band portion 1 is formed. It is formed so as to protrude toward the tip side of the portion 44. Hereinafter, of the inner part forming the through hole 33, the surface on which the band locking portion 2 is formed is referred to as a first surface 411, and the surface facing the first surface 411 is referred to as a second surface 412.

  As shown in FIG. 6, the band locking portion 2 is formed to be continuous with the first surface 411 at the root portion 29. On the other hand, in the natural state, a gap is formed between the front end portion of the band locking portion 2 and the first surface 411. That is, in the natural state, the tip side portion of the band locking portion 2 is formed away from the first surface 411 and inclined toward the second surface 412 side. And the front-end | tip of the band latching | locking part 2 is made into a free end, and can be elastically deformed so that the space | interval of the band latching | locking part 2 and the 1st surface 411 may become narrow.

  The band locking portion 2 is formed with locking protrusions 22 that can be selectively locked to the plurality of locking recesses 12 of the band portion 1. The present embodiment is an example in the case where two locking projections 22 are formed on the band locking portion 2. In addition, the case where the one latching convex part 22 is formed in the band latching | locking part 2 or the case where three or more are formed is also considered.

  Here, the band portion 1 is wound around the electric wire portion 9, and the end portion 13 opposite to the hinge portion 11 side of the band portion 1 is inserted into the through hole 33 from the one opening 331 side. And the state by which the band part 1 was wound around the electric wire part 9 by the latching convex part 22 of the band latching part 2 selectively latching in the some latching recessed part 12 of the band part 1 was carried out. Maintained. The locking projections 22 of the band locking portion 2 and the plurality of locking recesses 12 of the band portion 1 are selectively locked according to the thickness of the electric wire portion 9.

  Next, the support protrusion part 31 in the support part 3 is demonstrated. The support part 3 is a part that can support the electric wire part 9. As described above, in the present embodiment, the support protrusion 31 includes the first protrusion 311, the positioning protrusion 99, and the second protrusion 312.

  As shown in FIGS. 1 and 5, the first projecting portion 311 forms a recess 310 that can accommodate at least a part of the wire portion 9. In the present embodiment, as shown in FIGS. 1 and 5, the first protruding portion 311 is formed in a wall shape extending in the width direction of the electric wire portion 9.

  In addition, as another aspect, the 1st protrusion part 311 can also be considered as a pair of convex part provided in the width direction of the electric wire part 9 at intervals. In this case, a pair of convex portions form the recess 310.

  Further, in the present embodiment, the support protrusion 31 includes a pair of first protrusions 311 arranged in the extending direction of the electric wire part 9. Here, as shown in FIGS. 1, 3, and 5, the centers of the recesses 310 of the pair of first protrusions 311 coincide with each other in the extending direction of the first protrusion 311 (the width direction of the electric wire part 9). A pair of first projecting portions 311 are formed at the positions where the first projecting portions 311 are to be performed.

  In addition, in the width direction of the electric wire portion 9, a pair of second protrusions 312 described later are connected to both ends of the first protrusion 311. For this reason, it is conceivable that the pair of second protrusions 312 is difficult to deform in the width direction due to the first protrusions 311 interposed therebetween.

  The recess 310 in the first protrusion 311 is a recess that can accommodate at least a part of the electric wire portion 9. In the present embodiment, the recess 310 means that the relatively small diameter electric wire portion 9 moves in the extending direction and the width direction of the electric wire portion 9. The relatively small-diameter electric wire portion 9 is, for example, when the electric wire portion 9 is a single electric wire, when the electric wire portion 9 is constituted by a relatively small number of wires, or when the electric wire portion 9 is relatively thin. The case where it is a bundle of electric wires etc. can be considered.

  Further, in the present embodiment, as shown in FIG. 5, the recess 310 is an inclined surface that gradually inclines toward the bottom 51 side of the recess 310 as it goes to the middle of the recess 310 when viewed from the extending direction of the electric wire portion 9. including. More specifically, here, the recess 310 includes a bottom portion 51 that is a flat portion, a pair of inclined portions 52 that are inclined gradually from both ends of the first protruding portion 311 toward the bottom portion 51 side, including. The bottom 51 and the pair of inclined parts 52 are connected to each other. That is, here, the recess 310 is formed in a V-shape. In this case, the electric wire portion 9 is guided to the bottom portion 51 side along the inclined surfaces of the pair of inclined portions 52. That is, the electric wire portion 9 can be stably supported by the bottom portion 51 of the recess 310.

  Moreover, since the 1st protrusion part 311 has a width | variety in the extension direction of the electric wire part 9 here, the dent 310 and the electric wire part 9 accommodated in this dent 310 contact on a surface. In this case, the wire portion 9 can be supported more stably than when the dent 310 and the wire portion 9 are in point contact.

  Next, the positioning convex part 99 will be described. The positioning convex portion 99 is provided at a position different from the first protruding portion 311 in the extending direction of the electric wire portion 9. Here, the positioning convex part 99 is provided between the pair of first protrusions 311 in the extending direction of the electric wire part 9. And as FIG. 5 shows, the positioning convex part 99 is the electric wire part 9 side (opposite side with respect to the other party fixing | fixed part 4 side) from the dent 310 seeing from the extending direction of the electric wire part 9. As shown in FIG. It protrudes. Here, the positioning convex portion 99 is formed so as to protrude larger than the bottom portion 51 of the recess 310 of the first projecting portion 311 from the one opening 331 of the support portion 3 toward the opposite side to the counterpart fixing portion 4 side. Yes. Thereby, the electric wire part 9 contacts the positioning convex part 99 in the state accommodated in the dent 310 of the 1st protrusion part 311. FIG.

  In addition, in this embodiment, the contact surface 991 which can contact the electric wire part 9 in the positioning convex part 99 is a curved surface. Here, as shown in FIGS. 1 and 5, the tip end side (wire portion 9 side) portion of the positioning convex portion 99 is rounded. Thereby, the contact surface 991 of the positioning convex part 99 is comprised by the smooth curved surface without an angle | corner. In this case, it can suppress that the electric wire part 9 is damaged by the contact surface 991 contacting the electric wire part 9. FIG.

  Moreover, in this embodiment, as FIG.1, 6 shows, the positioning convex part 99 is extended in the part ranging from the root part 29 of the band latching | locking part 2 to the one opening 331. As shown in FIG. Here, the positioning convex portion 99 is continuous with the root portion 29 of the band locking portion 2. The positioning protrusion 99 is formed so as to protrude from the root portion 29 of the band locking portion 2 inside the through hole 33 to the electric wire portion 9 side through the one opening 331. In this case, the positioning convex part 99 also serves as reinforcement of the band locking part 2. In other words, the positioning protrusion 99 reinforces the base portion 29 of the band locking portion 2, thereby suppressing excessive elastic deformation of the band locking portion 2. In this case, the locking structure between the band portion 1 and the band locking portion 2 can be further sustained.

  Moreover, in this embodiment, as FIG.3, 9 shows, the positioning convex part 99 is provided in the hinge part 11 side rather than the one straight line L which passes along the center of the dent 310 of a pair of 1st protrusion part 311. Yes. And the positioning convex part 99 is provided in the position which contacts the electric wire part 9 supported by the dent 310 of a pair of 1st protrusion part 311, and bends the electric wire part 9 between a pair of 1st protrusion part 311. Yes. In this case, as shown in FIG. 9, the electric wire part 9 accommodated in the recess 310 of the pair of first protrusions 311 is in contact with the positioning protrusion 99, thereby being hinged between the pair of first protrusions 311. It bends in a shape pushed out to the opposite side with respect to the part 11 side. Here, as shown in FIG. 9, the band of the electric wire portion 9 is viewed from the extending direction of the electric wire portion 9 in a state where the electric wire portion 9 is accommodated in the recess 310 and the band portion 1 is wound around the recess 310. It can be said that the positioning convex part 99 is provided at a position where a part on the opposite side to the part side contacting the part 1 and a part of the positioning convex part 99 overlap. In the present embodiment, the positioning convex portion 99 extends along the extending direction of the electric wire portion 9 at a position coinciding with the middle of the recess 310 when viewed from the extending direction of the electric wire portion 9 and can contact the electric wire portion 9. The contact surface 991 is included. In this case, it is suppressed that the electric wire part 9 contacts the positioning convex part 99 with an excessively strong force.

  Moreover, in this embodiment, the hinge part 11 is a part which can deform | transform from a connection part with the support part 3 so that the electric wire part 9 may be covered. For this reason, it is conceivable that the electric wire portion 9 contacts the positioning convex portion 99 on the opposite side of the portion of the electric wire portion 9 that contacts the band portion 1.

  Next, the 2nd protrusion part 312 is demonstrated. In the present embodiment, the support protrusions 31 are formed on both sides of the recess 310 of the first protrusion 311 in the direction intersecting the extending direction of the electric wire part 9 (the width direction of the electric wire part 9), and the first protrusions A pair of second projecting portions 312 projecting larger than 311 is included.

  In the present embodiment, as shown in FIG. 1, the pair of second projecting portions 312 are formed in a wall shape along the extending direction of the electric wire portion 9. Here, the pair of second projecting portions 312 are formed side by side in the extending direction of the electric wire portion 9. More specifically, two pairs of second protrusions 312 are formed on each side of the through hole 33 in the extending direction of the electric wire portion 9. Therefore, the clamp 100 has a total of four second protrusions 312. Here, the four second projecting portions 312 are provided at positions that are continuous with the ribs 322 of the concave portion 321 of the body portion 32. Of course, the number of the second protrusions 312 formed on the clamp 100 may be other than the above.

  In this embodiment, a pair of 2nd protrusion part 312 mainly contact | abuts the comparatively large diameter electric wire part 9, and the comparatively large diameter electric wire part 9 moves to the extension direction and its width direction. It is the part which suppresses. In addition, the comparatively large diameter electric wire part 9 can consider the case where the electric wire part 9 is comprised by the comparatively large number of electric wires, or the case where the electric wire part 9 is a bundle of a comparatively thick electric wire etc., for example.

  Here, the second protrusion 312 is formed in a shape that gradually becomes thinner toward the tip, and further, the tip portion is formed in a rounded shape. That is, here, the second protruding portion 312 is formed in a tapered shape, and an angular portion is not formed at the tip thereof. In this case, the second protrusion 312 is likely to bite into the relatively large diameter electric wire portion 9. In addition, since there is no corner at the tip of the second protrusion 312, it is possible to prevent the electric wire 9 from being damaged when the second protrusion 312 contacts the electric wire 9. Of course, a case where the tip of the second protruding portion 312 is formed so sharp as not to damage the electric wire portion 9 is also conceivable.

  Next, the clamped electric wire 110 when the electric wire portion 9 has a relatively small diameter will be described with reference to FIGS. In this case, the movement of the electric wire portion 9 in the extending direction is mainly suppressed by the first protruding portion 311 and the positioning convex portion 99.

  That is, in the state where the band portion 1 is wound and the band portion 1 and the band locking portion 2 are locked, the electric wire portion 9 has a pair of first protruding portions 311 as shown in FIGS. Is supported by the bottom 51 of the recess 310. At this time, as shown in FIG. 8, the electric wire portion 9 comes into contact with the positioning convex portion 99 that protrudes to the electric wire portion 9 side from the bottom portion 51 of the recess 310. And the positioning convex part 99 presses the electric wire part 9 to the part side which the electric wire part 9 and the band part 1 contact. Thereby, it is suppressed that the electric wire part 9 moves in the extension direction.

  Moreover, as FIG. 9 shows, the electric wire part 9 has the shape bent by the positioning convex part 99 between a pair of 1st protrusion parts 311 here. In this case, the electric wire portion 9 is more strongly pressed by the positioning convex portion 99, and the movement along the extending direction is further suppressed.

  Furthermore, in the present embodiment, the electric wire portion 9 is bent along the main surface on one side of the central region (the recessed portion) of the pair of wall portions 15 and the long portion 14 of the band portion 1, and the shape thereof is Maintained. For this reason, it is suppressed more effectively that the electric wire part 9 moves along the extension direction. In addition, the case where the band part 1 can deform | transform along the bent electric wire part 9 is also considered. In this case, even if the band part 1 is flat, it is considered that the electric wire part 9 is more effectively suppressed from moving along the extending direction.

  On the other hand, when the electric wire portion 9 has a relatively large diameter, the movement of the electric wire portion 9 in the extending direction is mainly suppressed by the second protruding portion 312.

  That is, in the state in which the band portion 1 is wound and the band portion 1 and the band locking portion 2 are locked, the electric wire portion 9 has two pairs of second protrusions arranged side by side as shown in FIG. The part 312 is supported while being bitten. Thereby, the movement in the extending direction of the electric wire part 9 is suppressed. At this time, it is conceivable that the first protruding portion 311 and the positioning convex portion 99 also bite into the electric wire portion 9 and suppress the movement of the electric wire portion 9 in the extending direction.

  And in this embodiment, the electric wire part 9 which was covered to the clamp 100 by the band latching | locking part 2 in the state which the clamp 100 and the circumference | surroundings were covered by the band part 1 of the clamp 100, and the band part 1 was wound, The clamped electric wire 110 is fixed by being inserted into the fixing hole 81 of the counterpart member 8. Thereby, the electric wire part 9 can be attached to the other party member 8 using the clamp 100.

<Effect>
In the present embodiment, at least a part of the electric wire portion 9 is accommodated in the recess 310 of the first projecting portion 311, and the band portion 1 is wound around the periphery. The state where the band portion 1 is wound around the wire portion 9 is maintained by the band locking portion 2. In this case, when the positioning convex part 99 contacts the electric wire part 9 around which the band part 1 is wound, it is possible to suppress the electric wire part 9 from moving along the extending direction of the electric wire part 9. In this case, the electric wire portion 9 can also be prevented from rotating in the circumferential direction of the clamp 100, that is, rotating along the circumferential direction of the electric wire portion 9.

  Further, in the present embodiment, the relatively small diameter electric wire portion 9 moves in the extending direction and intersects the extending direction of the electric wire portion 9 by the recess 310 and the positioning convex portion 99 of the first projecting portion 311. The movement in the direction can be suppressed. In addition, the pair of second protrusions 312 can suppress the movement of the relatively large-diameter electric wire portion 9 in the extending direction and the direction intersecting the extending direction of the electric wire portion 9.

  Moreover, in this embodiment, since the contact surface 991 with the electric wire part 9 in the positioning convex part 99 is a curved surface, when the positioning convex part 99 contacts the electric wire part 9, the electric wire part 9 will be damaged. It can be suppressed more.

  Moreover, in this embodiment, since the dent 310 includes an inclined surface that gradually inclines toward the bottom 51 of the dent 310 as it goes to the middle of the dent 310 when viewed from the extending direction of the electric wire portion 9, the electric wire along the inclined surface is included. The part 9 can be guided to the bottom 51 of the recess 310 of the first protrusion 311. In this case, at least a part of the wire portion 9 can be more stably accommodated in the recess 310 of the first protruding portion 311. That is, the electric wire portion 9 is stably supported by the bottom portion 51 of the recess 310.

  Moreover, in this embodiment, since the positioning convex part 99 extends in the part ranging from the root part 29 of the band latching part 2 to the one opening 331, the band latching part 2 is reinforced by the positioning convex part 99. For this reason, the state in which the band portion 1 formed by the band portion 1 and the band locking portion 2 is wound around the electric wire portion 9 can be further maintained.

  In the present embodiment, the support protrusion 31 includes a pair of first protrusions 311 arranged in the extending direction of the electric wire part 9, and the positioning protrusion 99 is provided between the pair of first protrusions 311. For this reason, it can suppress more that the electric wire part 9 moves to the extension direction and its width direction.

  Moreover, in this embodiment, the electric wire part 9 accommodated in the dent 310 of the 1st protrusion part 311 becomes a shape where it was pushed by the positioning convex part 99 in the location which contacts the positioning convex part 99, and bent. In this case, when a force is applied to move the electric wire portion 9 along the extending direction of the electric wire portion 9, the electric wire portion 9 comes into stronger contact with the positioning convex portion 99. For this reason, it can suppress more that the electric wire part 9 moves to the extension direction.

<Modification>
Next, a clamp 100X according to a modification will be described with reference to FIGS. FIG. 11 is a plan view of the clamp 100X as viewed from the support protrusion 31 side. FIG. 12 is a front view of the clamp 100X. 11 and 12, the same reference numerals are given to the same components as those shown in FIGS.

  In this example, as shown in FIGS. 11 and 12, the recess 310X has a different shape from the recess 310 of the clamp 100 of the embodiment.

  In other words, in this example, the recess 310 </ b> X includes a pair of side wall parts 53 in addition to the bottom part 51 and the pair of inclined parts 52. The pair of side wall portions 53 are interposed between the bottom portion 51 and the pair of inclined portions 52, respectively.

  In this example, the recess 310X includes a bottom surface and a pair of side surfaces protruding from the bottom surface side to the electric wire portion 9 side. The bottom surface and the pair of side surfaces are orthogonal to each other. Here, as shown in FIG. 12, the surface of the bottom 51 on the side of the electric wire 9 forms the bottom of the recess 310 </ b> X, and the surface of the pair of side walls 53 on the side of the electric wire 9 forms a pair of side surfaces. In this case, when the electric wire part 9 supported by the bottom part 51 of the dent 310X moves in the width direction of the electric wire part 9, it contacts the pair of side wall parts 53 in which the pair of side surfaces are formed. Here, the pair of side surfaces are provided so as to be orthogonal to the bottom surface. For this reason, it can suppress more that the electric wire part 9 moves from the bottom part 51 of the dent 310X by moving in the width direction. More specifically, here, the movement of the electric wire portion 9 from the bottom portion 51 to the inclined portion 52 is more reliably suppressed.

  In this example, the pair of side wall portions 53 and the bottom portion 51 are connected via an arc-shaped portion. That is, the pair of side surfaces and the bottom surface are connected via an arcuate curved surface. However, when the pair of side wall portions 53 and the bottom portion 51 are connected at an angle, for example, the pair of side surfaces and the bottom surface may be connected at an angle of 90 degrees. As another aspect, a case where the inclined surface in the recess 310X is a flat surface is also conceivable.

  Also in this example, the positioning protrusion 99 comes into contact with the wire portion 9 supported by the recess 310X of the pair of first protrusions 311 and bends the wire portion 9 between the pair of first protrusions 311. Is provided. More specifically, as shown in FIG. 11, the positioning convex portion 99 is provided on the hinge portion 11 side with respect to one straight line L passing through the center of the recess 310 </ b> X of the pair of first projecting portions 311. In addition, it is possible that the center of the dent 310X in this example means the center in the part between a pair of side surfaces of the dent 310X. Here, as shown in FIG. 12, the positioning convex portion 99 extends in the extending direction of the electric wire portion 9 at a position that coincides with the center of the portion between the pair of side surfaces of the recess 310 </ b> X when viewed from the extending direction of the electric wire portion 9. , And includes a contact surface 991 that can come into contact with the wire portion 9.

  Also in this example, at least a part of the wire portion 9 is accommodated in the recess 310X of the first projecting portion 311 and the band portion 1 is wound around the periphery. The state where the band portion 1 is wound around the wire portion 9 is maintained by the band locking portion 2. In this case, when the positioning convex part 99 contacts the electric wire part 9 around which the band part 1 is wound, it is possible to suppress the electric wire part 9 from moving along the extending direction of the electric wire part 9. In this case, the electric wire portion 9 can also be prevented from rotating along the circumferential direction.

  Further, in this example, the recess 310X includes a bottom surface and a pair of side surfaces protruding from the bottom surface side to the electric wire portion 9 side, and the pair of side surfaces and the bottom surface are orthogonal to each other. For this reason, when the force which moves to the width direction of the electric wire part 9 is applied with respect to the electric wire part 9 accommodated in the dent 310X of the 1st protrusion part 311, the electric wire part 9 is contact | abutted by a pair of side surface. The movement in the width direction can be more effectively suppressed.

<Application example>
In the above-described embodiment, the support protrusion 31 includes a pair of first protrusions 311. However, a case where the support protrusion 31 includes one first protrusion 311 or a case where the support protrusion 31 includes three or more first protrusions 311 is also conceivable.

  The clamp and electric wire with clamp according to the present invention can be freely combined with the above-described embodiment, modification and application examples within the scope of the invention described in each claim, or the embodiment and modification. Further, the present invention can be configured by appropriately modifying or omitting some of the application examples.
