JP 2000-134760 A

  The protector described in Patent Document 1 includes both a structure for fixing the cover to the protector main body and a structure for fixing the protector main body and the cover to the attachment body. The structure is complicated. Specifically, the protector is a locking portion formed in a portion of the protector body facing the cover, a locked portion formed in a portion of the cover facing the protector body, and The clip of the shape which protrudes toward the outer side from the outer surface of the said protector main body is provided. Therefore, the structure of the protector is very complicated.

  An object of the present invention is to provide a protector that can achieve both the fixing of the cover to the protector body and the fixing of the protector body and the cover to the attachment body with a simple structure.

  As means for solving the above-mentioned problems, the present invention is a protector that protects a wire bundle and is fixed to an attachment body having a front surface and a back surface together with the wire bundle, and surrounds a space that opens in a specific direction. A protector main body having a shape, a cover configured to close the opening, and a fixing portion capable of fixing the protector main body to the attachment body. The fixing portion is connected to the protector main body, and the opening of the protector main body There is provided a protector having a shape capable of fixing the protector body to the attachment body in a state where the cover in a closed posture for closing the cover is sandwiched between the protector body and the attachment body.

  According to the present invention, the fixing portion has a shape capable of fixing the protector to the mounting body in a state where the cover in a closed posture is sandwiched between the protector body and the mounting body. Without providing a dedicated structure for fixing the cover to the main body, the protector main body can be fixed to the attachment body while the cover is held in a closed position with respect to the protector main body.

  In this case, the cover has an insertion hole through which the fixing portion can be inserted in the closed posture, and the fixing portion faces the cover in the closed posture of the protector body through the space. The fixing portion main body having a shape that extends from the part to be passed through the insertion hole of the cover in the closed position and extends to the back surface of the mounting body in a state where the cover in the closed position is in contact with the surface of the mounting body And the attachment in a state where the cover is sandwiched between the protector main body and the attachment body when the cover in the closed position is connected to the front end of the fixing portion main body and contacts the surface of the attachment body. An engagement portion shaped to contact the back surface of the body from the side opposite to the protector body, and the fixed body is a portion of the protector body that contacts the cover in the closed position It is preferred that in a position opposed through the substantially center said space lines connecting the has led to the protector body.

  According to this configuration, when the protector body is fixed to the mounting body in the state where the cover is in the closed position, a portion of the outer surface of the protector body on the back side of the fixing portion body faces the mounting body. By pressing, the pressing force is efficiently transmitted to the engaging portion, so that the mounting work of the protector to the mounting body is simplified.

  Specifically, the protector main body has a first edge and a second edge facing each other, and a bottom wall facing the cover in a posture parallel to the cover in the closed posture, and the first edge A first side wall standing upright from the second side wall and a second side wall standing upright from the second edge so as to face the first side wall, and the fixed body is perpendicular to the bottom wall. It is preferable that the first side wall and the second side wall are connected to a substantially central portion.

  In the present invention, the engagement portion is connected to a distal end of the fixed portion main body, and the cover in the closed posture is in a direction perpendicular to the thickness direction of the cover in a state where the cover is in contact with the surface of the attachment body. An engaging portion main body extending in the direction of the attachment body, and a contact portion extending from the engaging portion main body to the back side of the attachment body and in contact with the back surface, and the engaging portion main body includes the cover in the closed position. The contact portion is elastically deformed so as to be displaced in a direction away from the cover by a reaction force received from the back surface of the attachment body when contacting the surface of the attachment body, and the contact with the elastic return force It is preferable to press the part against the back surface of the mounting body.

  In this way, when the cover in the closed position comes into contact with the surface of the attachment body, the contact portion is pressed against the back surface of the attachment body by the elastic return force of the engagement portion body. Since the attachment body is sandwiched between the engagement portion and the cover from both sides in the thickness direction, rattling of the protector with respect to the attachment body is suppressed. For this reason, even if it is a case where an attachment body vibrates, drop-off | omission of a protector from the said attachment body resulting from the vibration is suppressed.

  Furthermore, the tolerance of the attachment body can be absorbed by the elastic deformation of the engagement portion main body. Specifically, the engagement portion body is elastically deformed so as to allow the contact portion to be displaced in a direction away from the cover by a reaction force received from the back surface of the attachment body. When the thickness of the body is slightly larger than a standard value, the engagement portion main body is elastically deformed so that the contact portion is displaced in a direction away from the cover, and the elastic return force of the engagement portion main body The contact portion is pressed against the back surface of the mounting body. For this reason, the tolerance of the attachment body is absorbed, and the attachment state of the attachment body by the engagement portion and the cover is ensured.

  In the present invention, at least the distal end portions of the engaging portion and the fixed portion main body are divided into a plurality of flexible pieces and at least the distal ends of the engaging portion and the fixed portion main body are separated from each other. Are formed so that they can be elastically bent and deformed in the direction in which they approach each other, and the plurality of flexible pieces have outer shapes set larger than the insertion holes, and the insertion holes When passing through the inside, it is preferable that the outer shape bends and deforms so as to have a size capable of passing through the insertion hole.

  By doing so, the cover can be temporarily locked to the protector main body before the protector is fixed to the attachment body, so that the fixing operation of the protector to the attachment body becomes simple. Specifically, the outer shape of the plurality of flexible pieces is large enough to pass through the insertion hole when passing through the insertion hole, and after passing through the insertion hole, the outer shape of the plurality of flexible pieces is larger than the insertion hole. Therefore, after the plurality of flexible pieces pass through the insertion hole, the cover is maintained in a state of being locked to the protector body. In addition, since the slit is formed so as to extend from the engagement portion to at least the distal end portion of the fixed portion main body, sufficient bending of the distal ends of the plurality of flexible pieces is ensured.

  Moreover, in this invention, it is preferable that the said fixing | fixed part further has the to-be-wrapped part which can extend from the said fixing | fixed part main body in the direction orthogonal to the thickness direction of the said cover, and can wind the said wire bundle.

  In this way, the extra length of the wire bundle can be absorbed.

  As described above, according to the present invention, it is possible to provide a protector that can achieve both the fixing of the cover to the protector body and the fixing of the protector body and the cover to the attachment body with a simple structure.

It is a perspective view of the state where the protector of one embodiment of the present invention was fixed to the attachment body. It is a perspective view in the state where the cover of the protector shown in Drawing 1 is an open posture. FIG. 3 is a perspective view of the protector shown in FIG. 2 in a closed position. It is an enlarged view of the fixing | fixed part of the protector shown in FIG. It is a left view of the protector shown in FIG. It is sectional drawing in the VI-VI line of the protector shown in FIG.

  A preferred embodiment of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the protector of the present embodiment includes a protector main body 10, a cover 20, and a fixing portion 30. FIG. 1 shows a state where the protector is fixed to a vehicle mounting bracket 50 as the mounting body 50.

A wire harness WH is placed on the bottom wall 12. Specifically, the wire harness WH is placed on the bottom wall 12 so that the axial direction of the wire harness WH is along the longitudinal direction of the bottom wall 12 (see FIG. 5).

  The first side wall 14 rises upward from the first edge 12 a in a posture orthogonal to the bottom wall 12. The first side wall 14 has a flat plate shape.

  The second side wall 16 is erected upward from the second edge 12 b in a posture orthogonal to the bottom wall 12. That is, the second side wall 16 faces the first side wall 14 in a posture parallel to the first side wall 14. In the present embodiment, the thickness in the front-rear direction of the second side wall 16 is set to be larger than that of the first side wall 14. A slit 16 a having a shape extending from the upper end to the lower end of the second side wall 16 is formed at the approximate center in the left-right direction of the second side wall 16. Therefore, the wire harness WH can be pulled out from the protector body 10 to the outside of the protector body 10 through the slit 16a. Further, the second side wall 16 is separate from the protector and can be connected to the protector body of the second protector having the same shape as the protector in the left-right direction, and the connected portion connected to the connecting portion 16b. It has the part 16c and the latching hole 16d which can latch the latching claw 26 mentioned later. The connecting portion 16 b is formed at the left end portion of the second side wall 16, and the connected portion 16 c is formed at the right end portion of the second side wall 16. The locking holes 16d are formed on both sides of the upper end of the second side wall 16 with the slit 16a interposed therebetween.

  The cover main body 22 has a rectangular shape in which the dimension in the left-right direction is larger than the dimension in the front-rear direction. The cover main body 22 is rotatable about the hinge part 24 at the end opposite to the hinge part 24. Specifically, the cover main body 22 is between an open posture (the posture of FIG. 2) that does not block the opening of the protector main body 10 and a closed posture (the posture of FIG. 1, FIG. 3, or FIG. 5) that closes the opening. The hinge part 24 can be turned around. The cover body 22 faces the bottom wall 12 in a posture parallel to the bottom wall 12 in the closed posture. The cover main body 22 has an insertion hole 22a through which the fixing portion 30 is inserted when in the closed posture. The insertion hole 22a has a shape whose dimension in the front-rear direction is larger than that in the left-right direction. The cover body 22 includes a connecting piece 22b that can be connected to the cover of the second protector, and a connected piece 22c that is connected to the connecting piece 22b. The connecting piece 22 b is formed at the left end of the cover main body 22, and the connected piece 22 c is formed at the right end of the cover main body 22.

  The locking claw 26 stands up in a posture orthogonal to the cover main body 22 from the end of the cover main body 22 opposite to the hinge portion 24. The locking claw 26 engages with the locking hole 16d when the cover body 22 changes from the open position to the closed position. As will be described later, since the cover 20 is temporarily locked to the protector body 10 in a closed position by the fixing portion 30, the locking claw 26 and the locking hole 16d may be omitted.

  The fixing portion 30 extends from the protector body 10 toward the cover 20 in the closed position, and the protector body 10 is attached to the vehicle mounting bracket 50 in a state where the cover 20 in the closed position is sandwiched between the protector body 10 and the vehicle mounting bracket 50. Fix it. In the present embodiment, the fixing portion 30 includes a fixing portion main body 32 extending upward in a posture orthogonal to the bottom wall 12 from between the first side wall 14 and the second side wall 16 of the bottom wall 12, and the fixing portion main body 32. And an engaged portion 35 that engages with the vehicle mounting bracket 50 and a wound portion 38 around which the wire harness WH can be wound. The fixed portion 30 is formed with a slit 30 a that divides the fixed portion 30 into a plurality of flexible pieces 39 along the circumferential direction about the vertical axis of the fixed portion 30. In the present embodiment, the slits 30 a are formed at four positions with an interval of 90 degrees with the axis as the center, and thereby, four flexible pieces 39 are formed in the fixed portion 30.

  The fixing portion main body 32 has a length extending from the bottom wall 12 through the insertion hole 22a of the cover 20 in the closed posture to the outside of the cover 20, more specifically, the fixing portion main body 32 is formed of the cover 20 in the closed posture. The length is set to reach the back surface 50b of the vehicle mounting bracket 50 when the upper surface contacts the surface 50a of the vehicle mounting bracket 50 (see FIG. 6). The fixing portion main body 32 is connected to the bottom wall 12 at the approximate center between the first side wall 14 and the second side wall 16 in the front-rear direction. As shown in FIG. 4, the fixed portion main body 32 includes a shaft portion 33 extending upward from the bottom wall 12 and a diameter expanding portion 34 having a shape that increases in diameter from the upper end of the shaft portion 33 upward. Have. The shaft portion 33 has a substantially cylindrical shape that is long in the vertical direction. The central axis of the shaft portion 33 coincides with the axis. As shown in FIG. 6 in FIG. 5, the enlarged diameter portion 34 is formed on the rear surface 50 b of the vehicle mounting bracket 50 from the upper end of the shaft portion 33, that is, the portion below the cover 20 in the closed posture of the fixed portion main body 32. Has a length up to The enlarged diameter portion 34 is elastically bent and deformed so as to allow displacement of the upper end thereof in a direction approaching the central axis of the shaft portion 33 or in a direction away from the central axis.

  The engaging part 35 is connected to the upper end of the enlarged diameter part 34. The engaging portion 35 engages with the back surface 50 b of the vehicle mounting bracket 50 when the upper surface of the cover 20 in the closed posture comes into contact with the front surface 50 a of the vehicle mounting bracket 50. Thereby, the cover 20 in the closed posture is sandwiched between the protector body 10 and the vehicle mounting bracket 50. The engaging portion 35 includes an engaging portion main body 36 connected to the upper end of the enlarged diameter portion 34, and a contact portion 37 connected to the lower surface of the engaging portion main body 36 and contacting the back surface 50 b of the vehicle mounting bracket 50. Have.

  The engaging part main body 36 has a shape in which the dimension in the direction away from the central axis of the shaft part 33 increases from the upper end toward the lower end. That is, the outer surface of the engaging portion main body 36 is an inclined surface that is inclined in a direction away from the central axis as it goes from the upper end to the lower end of the engaging portion main body 36. The lower end of the engaging portion main body 36 is located outside the portion outside the upper end of the enlarged diameter portion 34. The lower surface of the engagement portion main body 36 faces the rear surface 50b of the mounting bracket 50 in a state where the upper surface of the cover 20 in the closed posture is in contact with the front surface 50a of the vehicle mounting bracket 50. In the engaging portion main body 36, a concave portion 36a is formed on the inner side (on the side of the central axis) of the contact portion 37 so as to extend upward from its lower surface. For this reason, the engaging part main body 36 is orthogonal to the central axis of the shaft part 33 at the lower end of the recessed part 36a so as to allow the contact part 37 positioned outside the recessed part 36a to be displaced upward. It is possible to bend and deform elastically so as to increase the dimension in the direction. The engaging portion main body 36 is separated from the cover 20 by an upward reaction force that the contact portion 37 receives from the rear surface 50b of the vehicle mounting bracket 50 when the cover 20 in the closed posture comes into contact with the front surface 50a of the vehicle mounting bracket 50. While elastically deforming to allow displacement in the direction, the contact portion 37 is brought into pressure contact with the back surface 50b of the vehicle mounting bracket 50 by the elastic return force. In FIG. 6, for example, when the thickness of the vehicle mounting bracket 50 is slightly larger than the standard value, the engagement portion main body 36 is elastically deformed so that the contact portion 37 is slightly displaced upward. The situation is shown by a two-dot chain line.

  The contact portion 37 has a shape protruding downward from the lower surface of the engagement portion main body 36. In the present embodiment, the contact portion 37 has a curved shape that protrudes downward. The contact portion 37 has a shape continuously connected in the circumferential direction around the central axis except for the slit 30a.

  The slit 30a is formed in a portion of the fixed portion 30 above the shaft portion 33, that is, the enlarged diameter portion 34 and the engaging portion 35, whereby the enlarged diameter portion 34 and the engaging portion 35 are It is divided into a plurality of (four in this embodiment) flexible pieces 39. For this reason, when an external force in a direction approaching the central axis acts on the engaging portion 35, each flexible piece 39 is elastic so as to allow displacement of the upper end of the flexible piece 39 in the direction toward the central axis. Bends and deforms. In the present embodiment, the insertion hole 22a allows the engagement portion main body 36 when the engagement portion main body 36 of the plurality of flexible pieces 39 is displaced so as to approach each other toward the central axis side. In this state, the engagement portion main body 36 is set in a shape that prevents the engagement portion main body 36 from being inserted when the engagement portion main body 36 is returned to the initial position (the position where the external force is not applied). In other words, the outer shape of the engaging portion main body 36 among the plurality of flexible pieces 39 is larger than the insertion hole 22a and closes to each other when passing through the insertion hole 22a. The size is set to allow passage.

  The wound portion 38 has a rectangular flat plate shape extending from the shaft portion 33 toward both sides in the left-right direction.

  Next, a method for fixing the protector to the vehicle mounting bracket 50 will be described. As will be described below, the fixing method of the present embodiment includes a wire harness placing step, a cover closing step, and a fixing step.

  First, the cover 20 is set in an open posture with respect to the protector body 10.

  In the wire harness placing step, the wire harness WH is placed on the bottom wall 12. At this time, when there is a surplus length of the wire harness WH, the surplus length is wound around the wound portion 38. In addition, the wire harness WH is pulled out through the slit 16a as needed.

  In the subsequent cover closing process, the cover body 22 is rotated around the hinge portion 24 so that the end of the cover body 22 on which the locking claw 26 is formed contacts the upper end of the second side wall 16. The Here, when the engaging portion 35 of the plurality of flexible pieces 39 passes through the insertion hole 22 a, the engaging portion main body 36 moves from the inner peripheral surface surrounding the insertion hole 22 a of the cover main body 22 to the central axis. The engaging portion main body 36 (tip portions of the plurality of flexible pieces 39) is displaced toward the central axis so as to reduce the diameter. Since the outer surface of the engaging portion main body 36 is an inclined surface that is inclined in a direction away from the central axis as it goes from the upper end to the lower end of the engaging portion main body 36, the engaging portion main body 36 is engaged as the cover 20 approaches the closed position. The joint body 36 is gradually reduced in diameter. Then, when the lower end of the engaging portion main body 36 passes through the insertion hole 22a, the plurality of flexible pieces 39 are elastically restored and the outer shape of the lower end of the engaging portion main body 36 becomes larger than the insertion hole 22a. The locking claw 26 engages with the locking hole 16d. In this state, as shown in FIG. 5, a gap corresponding to the thickness of the vehicle mounting bracket 50 is formed between the contact portion 37 and the upper surface of the cover main body 22. Further, even if the cover 20 is rotated in the opening posture in this state, the contact portion 37 restricts further rotation of the cover 20 by contacting the upper surface of the cover 20. It is held (temporarily locked) in the closed posture.

  In the fixing process, the top surface of the cover main body 22 faces the surface 50 a of the vehicle mounting bracket 50, and the bottom wall 12 is positioned so that the engaging portion 35 is inserted into the mounting hole 50 c formed in the vehicle mounting bracket 50. A portion of the outer surface of the shaft portion 33 on the back side is pressed toward the vehicle mounting bracket 50. At this time, the engaging portion 35 of the plurality of flexible pieces 39 is inserted into the mounting hole 50c while exhibiting the same behavior as when passing through the insertion hole 22a, and the upper surface of the cover 20 is the vehicle mounting bracket 50. When it comes into contact with the front surface 50a, the rear surface 50b of the vehicle mounting bracket 50 is engaged. In this state, as shown in FIG. 6, the contact portion 37 is pressed against the back surface 50 b of the vehicle mounting bracket 50 by the elastic return force of the engagement portion main body 36. That is, the vehicle mounting bracket 50 is sandwiched between the engaging portion 35 and the cover 20. The tolerance of the vehicle mounting bracket 50 is absorbed by the bending deformation of the engaging portion main body 36 (see FIG. 6).

  Here, the protector of the present embodiment described so far will be outlined.

  According to the protector of the present embodiment, the fixing portion 30 has a shape capable of fixing the protector to the vehicle mounting bracket 50 in a state where the cover 20 in the closed posture is sandwiched between the protector body 10 and the vehicle mounting bracket 50. The protector body 10 can be fixed to the vehicle mounting bracket 50 while the cover 20 is held in the closed posture with respect to the protector body 10. This makes it possible to eliminate or simplify a dedicated structure for fixing the cover to the protector body as in the prior art.

  The cover 20 has an insertion hole 22a through which the fixing portion 30 can be inserted when the cover 20 is in the closed posture. The fixing portion 30 passes through the insertion hole 22a of the cover 20 in the closed posture, and the cover 20 in the closed posture is The fixed portion main body 32 that extends so as to reach the back surface 50b of the vehicle mounting bracket 50 when in contact with the front surface 50a of the vehicle mounting bracket 50, and the cover 20 that is connected to the distal end of the fixed portion main body 32 and closed is attached to the vehicle. When the cover 20 is sandwiched between the protector body 10 and the vehicle mounting bracket 50 when coming into contact with the front surface 50a of the bracket 50, the engaging portion is in contact with the back surface 50b of the vehicle mounting bracket 50 from above. 35, and the fixed portion main body 32 is connected to the protector main body 10 at a position opposed to the approximate center of the line segment connecting the portions that contact the cover 20 in the closed posture through the space. When the protector body 10 is fixed to the vehicle mounting bracket 50 with the cover 20 in the closed position, the portion on the back side of the fixing portion body 32 on the outer surface of the protector body 10 is connected to the vehicle body 10. By pressing toward the mounting bracket 50, the pressing force is efficiently transmitted to the engaging portion 35, so that the mounting operation of the protector to the vehicle mounting bracket 50 becomes simple.

  In addition, the engaging portion 35 of the present embodiment is connected to the tip of the fixed portion main body 32 and extends from the engaging portion main body 36 in a shape extending in a direction orthogonal to the thickness direction of the cover 20. A contact portion 37 that extends toward the back surface 50b of the vehicle mounting bracket 50 and contacts the back surface 50b. The engagement portion main body 36 contacts when the cover 20 in the closed position contacts the surface 50a of the vehicle mounting bracket 50. The portion 37 is elastically deformed so as to be allowed to displace in a direction away from the cover 20 due to a reaction force received from the back surface 50b of the vehicle mounting bracket 50, and the contact portion 37 is moved to the back surface 50b of the vehicle mounting bracket 50 by the elastic return force. Therefore, when the cover 20 in the closed position comes into contact with the front surface 50a of the vehicle mounting bracket 50, the contact portion 37 is pressed against the back surface 50b of the vehicle mounting bracket 50 by the elastic return force of the engaging portion main body 36. Since the pressure, i.e., the vehicle mounting bracket 50 so is sandwiched between the engaging portion 35 and the cover 20 from both sides in the thickness direction, rattling of the protector to the vehicle mounting bracket 50 is suppressed. For this reason, even if it is a case where the vehicle mounting bracket 50 vibrates, the drop-off | omission of a protector from the vehicle mounting bracket 50 resulting from the vibration is suppressed.

  Furthermore, the tolerance of the vehicle mounting bracket 50 can be absorbed by the elastic deformation of the engaging portion main body 36. Specifically, the engaging portion main body 36 is elastically deformed so as to allow the contact portion 37 to be displaced in a direction away from the cover 20 due to a reaction force received from the back surface 50b of the vehicle mounting bracket 50. When the thickness of the vehicle mounting bracket 50 is slightly larger than the standard value, the engaging portion main body 36 is elastically deformed so that the contact portion 37 is displaced in a direction away from the cover 20, and the elasticity of the engaging portion main body 36 is also increased. The contact portion 37 is brought into pressure contact with the rear surface 50b of the vehicle mounting bracket 50 with a restoring force (see FIG. 6). For this reason, the tolerance of the vehicle mounting bracket 50 is absorbed, and the holding state of the vehicle mounting bracket 50 by the engaging portion 35 and the cover 20 is ensured.

  In the present embodiment, the engaging portion 35 and the enlarged diameter portion 34 of the fixed portion main body 32 are divided into a plurality of flexible pieces 39 and the flexible pieces 39 are divided into the flexible pieces 39. A slit 30a is formed that enables elastic deformation and deformation in a direction in which the members 39 approach each other, and the plurality of flexible pieces 39 have an outer shape set larger than the insertion hole 22a, and When passing through the insertion hole 22a, the outer shape is bent and deformed so that it can pass through the insertion hole 22a. Therefore, the cover 20 is rotated in the opening posture after the closing posture. However, when each flexible piece 39 contacts the upper surface of the cover 20, further rotation of the cover 20 is restricted, and the cover 20 is held in the closed posture. Therefore, since the cover 20 can be temporarily locked to the protector body 10 before the protector is fixed to the vehicle mounting bracket 50, the work of fixing the protector to the vehicle mounting bracket 50 becomes simple. This makes it possible to simplify or eliminate the structure of the locking hole 16a and the locking claw 26. Further, since the slit 30a is formed so as to extend from the upper end of the engaging portion 35 to the enlarged diameter portion 34 of the fixed portion main body 32, sufficient bending of the tips of the plurality of flexible pieces 39 is ensured.

  Moreover, since the fixing | fixed part 30 of this embodiment further has the to-be-wrapped part 38 which extends from the fixing | fixed part main body 32 in the direction orthogonal to the thickness direction of the cover 20, and can wind the wire harness WH, it is a wire. The extra length of the harness WH can be absorbed.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiment but by the scope of the claims, and includes all modifications within the meaning and scope equivalent to the scope of the claims.

  For example, in the above-described embodiment, an example in which the fixing portion 30 is provided at one location is shown, but the fixing portion 30 may be provided at two locations separated from each other in the left-right direction. If it does in this way, the fixed state with respect to the vehicle mounting bracket 50 of a protector will become more stable. Further, in this case, one fixing portion may be provided at the left end of the bottom wall 12, the other fixing portion may be provided at the right end of the bottom wall 12, and each fixing portion may not pass through the cover 20. Specifically, each of the fixed portions is covered by being pressed outward in the left-right direction from the corresponding end of the left and right ends of the cover body 22 when the cover 20 is in the closed posture. The cover 20 may be configured to allow the cover 20 to rotate while being bent outwardly with the main body 22 interposed therebetween. In this way, the insertion hole 22a of the cover 20 is omitted.

  Moreover, in the said embodiment, although the structure by which the cover 20 is temporarily latched by the protector main body 10 in the state of a closed attitude | position is shown, it is not restricted to this structure. That is, in the said embodiment, the external shape of the engaging part main body 36 among the some flexible pieces 39 is larger than the insertion hole 22a, and when passing through the insertion hole 22a, it approaches the said insertion hole. The insertion hole 22 a may be set to be larger than the outer shape of the engaging portion main body 36, although the size is set to allow passage through the inside 22 a.

  Moreover, although the wire harness WH is illustrated as an electric wire bundle in the said embodiment, an optical fiber cable etc. may be sufficient as an electric wire bundle.
