Description

The present invention is, for example, connected to a vehicle body and a sliding door that opens and closes while sliding relative to the vehicle body so as to bridge each other, and is attached to a cable that bends and deforms following the opening and closing operation of the sliding door. It relates to a cable armor member.

Electrical components such as power window motors, switches, and speakers are incorporated in slide doors provided in vehicles such as automobiles. Cables such as wire harnesses are laid between the vehicle body and the sliding door in order to supply power to these electrical components from the vehicle body or transmit and receive various control signals to and from the vehicle body. (See Patent Document 1, for example).

Patent Document 1 discloses a bellows-shaped corrugated tube in which concave portions and convex portions extending in the circumferential direction are alternately arranged along the longitudinal direction as a cable sheathing member that is sheathed along the longitudinal direction of the cable. there is
As exemplified by the corrugated tube of Patent Literature 1, the cable armoring member bends and deforms along with the cable provided inside, following the opening/closing operation of the slide door. For example, in the process of opening and closing the slide door, the cable armor member bends in a U-shape in a plan view at the excess length between the vehicle body and the slide door.

However, depending on the specifics of the projecting portion of the U-shaped folded portion toward the vehicle body, the cable sheathing member may be in a position where the slide door is in the middle of opening or closing, such as a half-open position, or in a fully open position. Regardless of the situation, there is a risk that the projecting portion toward the vehicle body may enter the vehicle body.

For example, when the portion of the cable armor member that extends toward the vehicle body enters the vehicle body, there is a risk that it will interfere with vehicle body parts such as interior fittings provided in the vehicle body.

If the protruding portion of the cable armor member repeatedly interferes with the vehicle body part each time the slide door is opened and closed, the protruding portion may be damaged and the cable protecting function of the cable armor member may be reduced.

In addition, the cable sheathing member is not limited to the case where the slide door is in the middle of opening or closing the door or in the fully open position. may run on the step surface of In this case, when the occupant steps on the step surface portion, the occupant may accidentally step on the overhanging portion and damage the overhanging portion, or the occupant's smooth getting on and off operation may be hindered.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and continuously restricts the intrusion of the cable, which deforms following the opening/closing operation of the sliding door, into the inside of the vehicle body during the opening/closing operation of the sliding door. It is an object of the present invention to provide a cable sheathing member capable of

The present invention is an armored cable that is connected so as to bridge between a vehicle body and a sliding door that opens and closes a door opening while sliding relative to the vehicle body, and that bends and deforms following the opening and closing operation of the sliding door. a cable armoring member that is mounted along the longitudinal direction of the cable, and an armoring member body that is armored along the longitudinal direction of the cable; A guide portion is provided to set the direction orthogonal to the longitudinal direction of the cable in plan view of the vehicle body to the thickness direction of the cable, and the direction orthogonal to the longitudinal direction and the thickness direction of the cable to the vertical direction of the cable. , the guide portion extends in at least one of the vertical directions with respect to the exterior member main body so as to be able to abut on the vehicle body side from the outside of the vehicle body, and the guide portion extends along the longitudinal direction of the exterior member main body. It is characterized in that it is formed continuously at a portion corresponding to at least the overhanging portion in the direction.

According to the above configuration, it is possible to prevent the cable, which deforms following the opening/closing operation of the slide door, from entering the inside of the vehicle body.

More specifically, when the slide door is opened and closed, the cable is bent and deformed into a shape corresponding to the opening/closing position of the slide door, following the opening/closing operation. For example, depending on the opening/closing position of the sliding door, the cable is formed with a U-shaped folded portion between the vehicle body and the sliding door, and the folded portion of the cable moves following the opening/closing operation of the sliding door.

Depending on the opening/closing position of the sliding door, a portion of the folded portion of the cable may overhang in an attempt to enter the inside of the vehicle body. do.

On the other hand, since the guide portion is formed continuously along the longitudinal direction of the exterior member main body, it is possible to prevent the projecting portion, which moves sequentially, from entering the inside of the vehicle body when the sliding door is opened and closed. It can be continuously regulated by the guide part.

As a result, it is possible to prevent the cable from interfering with the cable when the passenger gets in and out of the passenger compartment, and the appearance of the cable is ensured by not protruding into the passenger compartment to a position where the passenger can see it. It can be played regardless of the open/closed position.

As an aspect of the present invention, a portion closer to the vehicle body than an intermediate position in the longitudinal direction of the exterior member main body is set as a vehicle body side portion of the exterior member main body, and the guide portion is configured to be the vehicle body side portion of the exterior member main body. It can be configured such that it is continuously formed in at least a part of the side portion along the longitudinal direction.

According to the above configuration, the guide portion is provided on the side facing the vehicle body in the U-shaped folded portion when the cable is bent and deformed into a folded shape (U-shaped) during opening and closing, such as when the slide door is in a half-open state. be done. Thus, the cable armor member can restrict the entry of the cable into the inside of the vehicle body by the guide portion while the slide door is being opened and closed.

On the other hand, the guide part is provided on the side facing the slide door in the U-shaped folded part when the cable is bent and deformed into a folded shape (U-turn shape) during opening and closing, such as when the sliding door is half-opened. do not have. Therefore, the cable armoring member can reduce the length of the guide portion in the longitudinal direction of the armoring member main body, thereby reducing the weight of the cable armoring member.

Further, as an aspect of the present invention, the cable is a flat cable formed in a flat shape in which the length in the vertical direction is longer than the length in the thickness direction, and the exterior member main body is capable of exteriorizing the cable. Secondly, it is formed to be one size larger than the cable in the thickness direction and the vertical direction, and is formed in the flat shape in the longitudinal direction including the portion having the guide portion.

According to the above configuration, since it is possible to give directionality to the bending characteristics (bending resistance) of the cable armoring member, even though the configuration includes the guide portion that extends continuously along the longitudinal direction of the armoring member body, , it is possible to achieve both excellent bending characteristics in the thickness direction of the cable armor member and suppression of sagging due to its own weight.

Further, as an aspect of the present invention, the guide portion may be formed to have the same length in the thickness direction as the exterior member main body.

According to the above configuration, there is no stepped portion or the like formed at the boundary between the guide portion and the exterior member body in the vertical direction, and the guide surface of the guide portion that abuts on the vehicle body side reaches the exterior member body in the vertical direction. It can be flush.

Note that the guide portion is not limited to having the same length in the thickness direction as the exterior member main body, but includes a length that differs to some extent (approximately ±10%).

Therefore, when the guide portion abuts on the vehicle body, the guide portion can be firmly abutted on the vehicle body side without the boundary portion between the guide portion and the exterior member main body getting caught on the vehicle body side.

Further, as a mode of the present invention, the exterior member main body and the guide portion may be integrally formed by a single elastic member.

In the cable armoring member of the present invention, the armoring member main body and the guide portion may be separate members, and the guide portion may be attached to the armoring member main body afterward. By adopting a configuration in which the member main body and the guide portion are integrally formed by a single elastic member, the number of parts can be suppressed and the configuration can be simplified.

Further, according to the above configuration, it is not necessary to retrofit the guide portion to the exterior member at the site or the like. In particular, in the present invention, since the guide portion is continuously formed along the longitudinal direction of the exterior member main body, when the guide portion is retrofitted to the exterior member, the guide portion can be formed along the longitudinal direction of the exterior member main body. Although it is necessary to attach them at a plurality of locations along the direction, since the exterior member main body and the guide portion are integrally formed of a single member as described above, such trouble is required. do not do.

Further, as an aspect of the present invention, in the exterior member main body, a concave portion having a concave cross section along the longitudinal direction and a convex portion having a convex shape both extend linearly in the vertical direction of the exterior member main body. At the same time, it is possible to adopt a configuration in which a plurality of bellows-like structures are alternately arranged along the longitudinal direction.

According to the above configuration, since the cable armor member is formed in a bellows shape along the longitudinal direction, it is easy to bend and deform in the thickness direction (that is, the increase in bending resistance can be alleviated) in a plan view of the vehicle body.

Further, as an aspect of the present invention, the concave portion and the convex portion at a portion corresponding to the guide portion in the longitudinal direction of the exterior member main body are formed continuously in the vertical direction up to the guide portion. can be configured.

According to the above configuration, the cable armor member is formed in a bellows shape along the longitudinal direction, including the guide portion. can mitigate the increase in

Therefore, the cable armor member can be prevented from projecting toward the vehicle body during bending deformation, and as a result, the cable armor member can be prevented from entering the vehicle compartment.

Further, according to the above configuration, since a plurality of protrusions extending in the vertical direction are arranged along the longitudinal direction of the guide section, the protrusions can function as ribs that reinforce the guide section.

That is, by forming the guide portion in a bellows shape, it is possible to make the guide portion less prone to bending deformation (deflection deformation) in a cross-sectional view perpendicular to the longitudinal direction.

As a result, when the guide portion comes into contact with the vehicle body, the guide function of the guide portion can be enhanced so that the exterior member main body does not intrude further into the vehicle body.

Further, as an aspect of the present invention, at least one side of the guide portion in the longitudinal direction has an extension length extending in at least one of the vertical directions with respect to the exterior member main body. A chamfered portion that gradually becomes smaller as it approaches at least one end of the above can be formed.

According to the above configuration, since the chamfered portion is formed on at least one side in the longitudinal direction of the guide portion, it is possible to suppress concentration of bending stress on at least one side during bending deformation of the exterior member main body. Therefore, the exterior member main body can be gently bent and deformed without being bent and deformed on at least one side during bending deformation.

Further, as an aspect of the present invention, an accommodation space for accommodating the cable is provided inside the exterior member main body, and an opening through which the cable is inserted into and taken out of the accommodation space is provided at a lower portion of the exterior member main body, It can be formed in a slit shape extending in the vertical direction along the longitudinal direction.

According to the above configuration, when the guide portion comes into contact with the vehicle body, the reaction force that the guide portion receives from the vehicle body side can act in the direction in which the opening closes.

As a result, when the guide portion abuts against the vehicle body, it is possible to prevent the opening portion from being inadvertently opened and the cable housed in the housing space to be exposed or to escape.

Further, as an aspect of the present invention, the opening has a slit shape extending in the vertical direction so as to pass through the inner side of the guide portion in the thickness direction and divide the guide portion into one side and the other side in the thickness direction. It can be a configuration formed in

Here, if the guide portion is formed without being divided in the thickness direction, the guide portion has a continuous thickness in the thickness direction compared to the case where the guide portion is divided in the thickness direction. Therefore, when the guide portion is bent and deformed in plan view of the vehicle body, an internal stress is generated due to a difference in path between the outer peripheral portion and the inner peripheral portion, and the bending resistance increases (that is, the bending resistance increases). difficult).

On the other hand, according to the above configuration, as described above, the guide portion is formed so as to be divided into one side and the other side in the thickness direction by the opening. Therefore, it is possible to suppress an increase in the bending resistance of the cable armor member during bending deformation in a plan view of the vehicle body due to the provision of the guide portion on the cable armor member.

Further, as an aspect of the present invention, the portion on the one side in the thickness direction of the guide portion is set to a portion on the side having the guide surface that contacts the vehicle body, and the portion on the other side in the thickness direction of the guide portion is set. The portion is set to a portion on the side having a non-guide surface that does not come into contact with the vehicle body, and the portion on the one side of the guide portion is formed longer in the thickness direction than the portion on the other side. can be done.

According to the above configuration, when the guide portion comes into contact with the vehicle body, the reaction force received by the guide portion from the vehicle body side is firmly absorbed by the one-side portion of the guide portion that is longer in the thickness direction than the other-side portion of the guide portion. can be accepted.

As a result, when the guide portion abuts against the vehicle body, it is possible to prevent the opening portion from being inadvertently opened and the cable housed in the housing space to be exposed or to escape.

Further, as an aspect of the present invention, the lower edge of the exterior member main body is arranged at a position higher than a step surface portion provided on the vehicle body so that a passenger can get in and out of the vehicle interior through the door opening, and the guide portion includes: The lower edge of the guide portion may extend downward from the exterior member main body so as to be located at a position lower than the step surface portion.

According to the above configuration, when the cable is bent and deformed, even if the cable tries to enter the inside of the vehicle body, the exterior member main body, which is placed at a position higher than the step surface portion, is positioned against the outer edge of the vehicle body of the step surface portion. It is possible to prevent damage caused by interfering with

On the other hand, the guide portion whose lower edge is located at a position lower than the step surface portion can be brought into contact with the vehicle body outer end of the step surface portion. Therefore, the guide portion can reliably prevent the overhanging portion of the cable toward the inside of the vehicle body from running over the step surface portion and entering the inside of the vehicle body.

According to the above configuration, the cable that deforms following the opening/closing operation of the slide door can be continuously prevented from entering the inside of the vehicle body during the opening/closing operation of the slide door.

A vehicle body 2 (see FIG. 1) provided with a sliding door 2 (see FIG. 1), and a sliding door 3 (see FIG. 1) that is provided on both left and right sides of the vehicle 1 and slides mainly in the longitudinal direction of the vehicle to open and close the door opening 21. It has

The cable sheathing member 10 of this embodiment is provided on both left and right sides of the vehicle 1 . However, since the main part of the vehicle 1 provided with the cable sheathing member 10 of this embodiment has a bilaterally symmetrical shape, the description will be based on the structure of the left side of the vehicle 1 unless otherwise specified.
Also, the vehicle 1, the slide door 3, and the cable 4 will be described prior to the description of the configuration of the cable sheathing member 10 of the present embodiment.

A synthetic resin scuff 23 (see, for example, FIGS. 6(b), 7, and 8), which is also called a step trim, is provided at the threshold portion 22 (see, for example, FIG. 6(b)) of the door opening 21 of the vehicle body 2. is provided.
As shown in FIGS. 7 and 8, the scuff 23 includes an upper surface portion 23a, a step surface portion 23b formed one step lower than the upper surface portion 23a at a position outside the upper surface portion 23a in the vehicle width direction, and a step surface portion 23b. 23a and the vehicle width direction inner end of the step surface portion 23b in the vertical direction of the vehicle; formed.

The upper surface portion 23a is arranged at substantially the same height as a floor panel (not shown) that forms the floor surface of the passenger compartment, and the step surface portion 23b is used as a stepping stone when the passenger gets in and out of the passenger compartment through the door opening 21. placed as high as possible. Both the upper surface portion 23a and the step surface portion 23b are formed in a horizontal plane. The storage portion 23d is formed so as to protrude upwardly with respect to the step surface portion 23b at a vehicle rear position relative to the step surface portion 23b, and has a space below for storing the vehicle body side mounting portion 5, which will be described later.

The sliding door 3 is provided on both the left and right sides of the vehicle 1 (only the left side of the vehicle is shown). A door inner panel 32 (see, for example, FIGS. 6A, 7, and 8) arranged on the inner side of the door and an inner panel of the sliding door 3 arranged on the inner side of the door inner panel 32 in the vehicle width direction. A door trim 33 (see the figure) is provided.

As shown in FIGS. 7 and 8, the door trim 33 has a peripheral edge such that a main wall 33a at the center thereof is spaced inwardly of the door inner panel 32 in the vehicle width direction when the door trim 33 is viewed from the front. 33b is joined to the outer peripheral portion of the door inner panel 32 from the inside in the vehicle width direction. Thereby, an accessory housing space 33s is formed inside the door trim 33 (that is, between the door trim 33 and the door inner panel 32). The accessory accommodation space 33 s accommodates various electrical components (not shown) mounted on the slide door 3 , such as a door actuator for driving the slide door 3 .

For example, as shown in FIGS. 6A, 7, and 8, the cable 4 is routed between the vehicle body 2 and the sliding door 3 so as to bridge them, as described above. As shown in FIGS. 1 and 2, the cable 4 is supported by a vehicle body mounting portion 5 mounted on the vehicle body 2 and a door mounting portion 6 mounted on the slide door 3 .

Specifically, one end side of the cable 4 in the longitudinal direction L is drawn into the vehicle body side mounting portion 5, and a connector 5a (FIG. 1, FIG. 1, (see FIG. 2). The connector 5a is connected to, for example, a battery as a power supply device mounted inside the vehicle body 2 or a wire harness extending from an electric component (not shown). That is, one end side of the cable 4 in the longitudinal direction L is electrically connected to the battery, electrical equipment, etc. mounted on the vehicle body 2 via the connector 5a.

The vehicle body side mounting portion 5 is stored below a storage portion 23d provided in the rear portion of the scuff 23 in the vehicle body 2 so as not to be visually recognized by passengers in the vehicle compartment (see FIG. 6(a)). In this state, the vehicle-body-side mounting portion 5 is, for example, as shown in FIG. 2) is attached to the vehicle body 2 .

The storage portion 23d is formed to open outward in the vehicle width direction so as not to interfere with the cable 4 (cable armor member 10) that deforms following the opening/closing operation of the slide door 3. As shown in FIG.

On the other hand, the other end of the cable 4 in the longitudinal direction L to which the cable sheathing member 10 is sheathed is pulled into the door-side mounting portion 6 and extends from the door-side mounting portion 6 inside the slide door 3 . It is connected to a connector 6a (see FIGS. 1 and 2). The connector 6a is connected to a wire harness (not shown) extending from an electrical component mounted inside the slide door 3. As shown in FIG. That is, the other end side of the cable 4 in the longitudinal direction L is electrically connected to the electrical component via the connector 6a.

As described above, the cable 4 can supply power to the electrical components mounted on the slide door 3 from the vehicle body 2 side, and transmit and receive control signals.

For example, as shown in FIGS. 6A, 7, and 8, the door-side mounting portion 6 is housed in the accessory housing space 33s inside the door trim 33 so as not to be seen from the outside of the sliding door 3. there is The door side mounting portion 6 has a seat portion 6b (see FIGS. 1 and 2) attached to the door inner panel 32 from the inside in the vehicle width direction. The door-side attachment portion 6 is attached to the slide door 3 so that the extending portion of the cable 4 (cable armor member 10) faces the front of the vehicle (see FIG. 6A, for example).

The door trim 33 has through holes (not shown) formed in the main wall 33a and the like. The extension portion of the cable 4 (cable armor member 10) from the door-side mounting portion 6 extends from the accessory housing space 33s to the vehicle width direction inner side of the door trim 33 (outside the sliding door 3) without interfering with the door trim 33. through the above through-holes.

The sliding door 3 opens and closes the door opening 21 by sliding mainly in the longitudinal direction of the vehicle with respect to the vehicle body 2 .
Specifically, as shown in FIG. 6(a), when the sliding door 3 is in the completely closed position Pc (fully closed position Pc), the outer surface of the sliding door 3 in the vehicle width direction (the outer surface of the door outer panel 31) is fitted into the door opening 21 so as to be substantially flush with the outer surface of the side portion of the vehicle body 2 . When the sliding door 3 is in the fully closed position Pc, the door side mounting portion 6 is located forward of the vehicle body side mounting portion 5 .

When the slide door 3 is opened from the fully closed position Pc, it moves rearward and outward in the vehicle width direction immediately after the start of the opening operation (see the thick arrow in FIG. 6B). In this manner, the sliding door 3 moves outward in the vehicle width direction immediately after the start of the opening operation, and then moves in a substantially straight line until it reaches the completely open position Po (fully open position Po) (see FIG. 6D). Move backward (see thick arrows in FIGS. 6(b) and 6(c)).
Strictly speaking, the sliding door 3 slides obliquely upward so that the position becomes slightly higher as it advances rearward.

While the slide door 3 moves rearward of the vehicle, the door side mounting portion 6 moves rearward of the vehicle relative to the vehicle body side mounting portion 5 . When the slide door 3 is in the fully open position Po, the door mounting portion 6 is located slightly behind the vehicle body mounting portion 5 (see FIG. 6(d)).
During the closing operation, the sliding door 3 slides in the opposite direction along the same trajectory as during the opening operation.

As shown in FIGS. 4(a), 4(b), 5(b), 7 and 8, in this embodiment, a known flat cable (FFC) is used as the cable 4. As shown in FIG.

As shown in FIGS. 4(a) and 4(b), the cable 4 as a flat cable is a power line and a signal line in a flat plate shape (the cross section orthogonal to the longitudinal direction L is flat), and is parallel to each other with a space therebetween. A plurality (four in this example) of conductors 41 having a rectangular cross section are sandwiched between a pair of film-like insulating materials 42 and laminated via an adhesive (not shown) to form a cover. .

The conductor 41 is made of a conductive material such as copper, aluminum, or an alloy thereof, and the insulating material 42 is made of an insulating material such as polyethylene terephthalate (PET).

Here, the width direction W of the cable 4 is set as the direction in which the plurality of conductors 41 are arranged in parallel. Also, the direction orthogonal to both the longitudinal direction L and the width direction W of the cable 4 is set as the thickness direction T of the cable 4 .

The cable 4 as a flat cable has bending characteristics such that it is easy to bend in the thickness direction T (excellent in flexibility) and difficult to bend in the width direction W. As shown in FIG. Such a cable 4 is arranged in a state in which the width direction W substantially coincides with the vertical direction of the vehicle when it is arranged in a substantially horizontal plane between the vehicle body 2 and the sliding door 3 .

That is, the cable 4 as a flat cable is formed in a flat shape that is longer in the vertical direction of the vehicle than the length in the thickness direction T. As shown in FIG. As a result, the cable 4 can be easily bent in a substantially horizontal plane due to the above-described bending characteristics of being formed as a flat cable.

Therefore, when the slide door 3 is opened and closed, the vehicle body side mounting portion 5 and the door side mounting portion 6 are relatively displaced within a substantially horizontal plane. Along with this, the cable 4 follows the opening/closing operation of the slide door 3 in a substantially horizontal plane, and is flexibly deformed into a bent shape according to the opening/closing position of the slide door 3 . That is, the sliding door 3 slides with respect to the vehicle body 2 but can maintain electrical connection with the vehicle body 2 .

Next, the cable sheathing member 10 of this embodiment will be described.
As shown in FIGS. 1, 2, 4(a)(b), and 5(a)(b), the cable sheathing member 10 of the present embodiment extends the cable 4 over the entire length in the longitudinal direction L as described above. It is formed in a tubular shape so as to be able to be accommodated inside over the length thereof, and is formed to have a length corresponding to the length of the cable 4 .

As a result, as shown in FIGS. 1 and 2, the cable sheathing member 10 is sheathed by the cable 4 routed so as to bridge the vehicle body 2 and the slide door 3, and the cable 4 extends over the entire length in the longitudinal direction L. protected throughout. One end side in the longitudinal direction L of the cable armoring member 10 is attached to the vehicle body side mounting portion 5 , and the other end side in the longitudinal direction L of the cable armoring member 10 is attached to the door side mounting portion 6 .

As shown in FIGS. 1 to 5(a) and (b), the cable armoring member 10 includes an armoring member main body 11 that armors the cable 4 along the longitudinal direction L, and a structure that allows the cable 4 to enter the inside of the vehicle body 2. It is integrally formed with a guide portion 15 for regulating.

In the cable armoring member 10, for example, the armoring member body 11 and the guide portion 15 are integrally formed of a single elastic member by blow molding or the like. The cable sheathing member 10 according to the present embodiment is entirely made of highly flexible elastomer resin, including the guide portion 15. However, the present invention is not limited to this, and any elastic member may be made of rubber or the like. good too.

The longitudinal direction L of the cable armoring member 10 (armoring member body 11 ) is assumed to coincide with the longitudinal direction L of the cable 4 . In the following description, the longitudinal direction L indicates not only the longitudinal direction of the cable 4 but also the longitudinal direction of the cable sheathing member 10 .

The exterior member main body 11 has a flat cross section perpendicular to the longitudinal direction L in the same manner as the cable 4 as a flat cable.

In the following description, the thickness direction T indicates not only the thickness direction of the cable 4 but also the thickness direction of the cable sheathing member 10 . Similarly, the width direction W indicates not only the width direction of the cable 4 but also the width direction of the cable armor member 10 .

As described above, the exterior member main body 11 has a flat orthogonal cross section in the longitudinal direction L, so unlike, for example, a cylindrical corrugated tube (not shown) spirally formed in the longitudinal direction L. , has directionality with respect to bending properties. Specifically, like the cable 4 , the exterior member main body 11 has bending characteristics such that it is easy to bend in the thickness direction T of the cable 4 and difficult to bend in the width direction W of the cable 4 .

As shown in FIGS. 4(a), 4(b), and 5(a), the exterior member main body 11 has a longitudinal housing space 16 for housing the cable 4 so as to be sheathed by the cable 4 as described above. It is formed in a hollow shape provided along the direction L.

The accommodation space 16 is formed so that a cross section orthogonal to the longitudinal direction L is one size larger than the cable 4 as a flat cable so as to be able to accommodate the cable 4 . Specifically, the lengths in the thickness direction T and the width direction W of the accommodation space 16 are slightly longer than the corresponding lengths of the cables 4 (see the same figure).
As a result, the cable 4 is wrapped around the exterior member main body 11 while ensuring a clearance with respect to the exterior member main body 11 .

As shown in FIGS. 2 and 4A, an opening 17 is formed along the longitudinal direction L in the lower edge 11d of the exterior member main body 11 for taking the cable 4 into and out of the accommodation space 16. As shown in FIG. As shown in FIG. 4( a ), the opening 17 has a width at an intermediate position in the thickness direction T of the lower edge 11 d of the exterior member body 11 so as to communicate the accommodation space 16 with the outside of the exterior member body 11 . It is provided in a slit shape (notch shape) extending in the direction W (vertical direction of the vehicle).

Edges 17a and 17b on both sides of the opening 17 are in close contact or close to each other in the thickness direction T, and the opening 17 is substantially closed. Furthermore, the opening 17 is normally kept substantially closed due to the elasticity (shape retention) of the exterior member body 11 itself (in particular, the edges 17a and 17b on both sides of the opening 17).

As shown in FIGS. 3 and 5A, the exterior member main body 11 has a cross section (horizontal cross section) along the longitudinal direction L, in which a plurality of concave portions 12 and convex portions 13 are alternately arranged along the longitudinal direction L. It is formed in a bellows shape provided. Both the concave portion 12 and the convex portion 13 extend linearly over substantially the entire circumference of the exterior member main body 11 (in the present example, along the width direction W to portions excluding the upper and lower ends of the exterior member main body 11). .

As shown in FIGS. 1, 2, 3, and 4B, the guide portion 15 extends downward with respect to the exterior member main body 11. As shown in FIGS.
Specifically, as shown in FIG. 8 , the exterior member main body 11 is arranged so that the lower edge 11 d of the exterior member main body 11 is positioned higher than the step surface portion 23 b provided on the vehicle body 2 . On the other hand, as shown in FIGS. 7 and 8, the guide portion 15 extends downward from the exterior member main body 11 so that the lower edge 15d of the guide portion 15 is arranged at a position lower than the step surface portion 23b. It is As a result, when the slide door 3 is opened and closed, the guide portion 15 reliably comes into contact with the vehicle width direction outer end 23bb of the step surface portion 23b even when the cable 4 is about to protrude toward the vehicle body 2 (FIGS. 7 and 8). 8), the cable 4 is regulated so as not to enter the vehicle body 2 side any further.

Further, as shown in FIGS. 1 to 3, the guide portion 15 is formed continuously along the lower edge 11d of the exterior member main body 11. As shown in FIGS. Thus, the guide portion 15 is formed in a planar shape extending in the longitudinal direction L of the cable sheathing member 10 and the vehicle vertical direction (width direction W).

Furthermore, as shown in FIGS. 1, 2, and 4B, the guide portion 15 is formed to have the same length (thickness) as the exterior member main body 11 in the thickness direction T. As shown in FIG. As a result, the surface on one side of the guide portion 15 in the thickness direction T, more specifically, the surface 15a (hereinafter also referred to as “guide surface 15a”) on the side in contact with the vehicle body 2 is one side in the thickness direction T of the exterior member main body 11. It is formed substantially flush with the side surface. Similarly, the surface of the guide portion 15 on the other side in the thickness direction T, more specifically, the surface 15b on the side not in contact with the vehicle body 2 (hereinafter also referred to as “non-guide surface 15b”) is substantially flush with the other side surface of the .

As shown in FIGS. 1 and 2, the guide portion 15 is located at an intermediate position 10M between the vehicle body side mounting portion 5 and the door side mounting portion 6 in the longitudinal direction L of the cable sheathing member 10. It is formed along the longitudinal direction L in at least a portion (in this example, a portion) of the portion 10B on the mounting portion 5 side (hereinafter also referred to as “vehicle side portion 10B”).

Here, the cable armor member 10 (cable 4) is bent and deformed as the slide door 3 is opened and closed, and along with this, a part of the cable armor member 10 (cable 4) in the longitudinal direction L becomes A projecting portion 19 projecting toward the room side is formed (see FIGS. 6(b) and 6(c)).

The guide portion 15 described above is formed continuously along the longitudinal direction at least at the projecting portion 19 in the longitudinal direction L of the cable sheathing member 10 . In this example, the guide portion 15 is formed continuously over the protruding portion 19 and the peripheral portion on the vehicle body side (vehicle rear side) with respect to the protruding portion 19 (see FIGS. 6B and 6C). ).

The position and length of the guide portion 15 formed in the longitudinal direction L of the cable sheathing member 10 are such that the cable 4, which deforms following the opening/closing operation of the slide door 3, can be restricted from entering the inside of the vehicle body 2. It is not limited to the configuration of the above-described embodiment, and may be formed with a different portion or length as long as it is a suitable portion.

Here, as described above, the opening 17 is formed along the longitudinal direction L in the lower edge 11d of the exterior member main body 11 (see FIGS. 2 and 4A). At a portion corresponding to the guide portion 15 in the longitudinal direction L of the cable sheathing member 10, the opening portion 17 extends continuously downward to the lower edge 15d of the guide portion 15 formed solid.

The opening 17 passes through the inner side of the guide portion 15 in the thickness direction T, and extends the guide portion 15 on one side (the side having the guide surface 15a) and the other side (the side having the non-guide surface 15b) in the thickness direction T. It is formed in a slit shape extending in the vertical direction of the vehicle so as to be divided.

In the present embodiment, the opening 17 is formed at an intermediate position in the thickness direction T so as to divide the guide portion 15 into approximately two parts in the thickness direction T. As shown in FIG. The opening 17 of the guide portion 15 is maintained in a substantially closed state during normal operation due to the elasticity of the guide portion 15 in the same manner as the exterior member main body 11 .

When the cable sheathing member 10 is sheathed to the cable 4, as shown by the phantom lines in FIGS. The cable 4 can be accommodated by inserting it into the housing (see medium thick arrows in FIGS. 4(a) and 4(b)).

When forming the cable sheathing member 10 by blow molding as described above, although not shown, the opening 17 is positioned inside the cable sheathing member 10 (accommodating space 16) set inside the mold. It is used as a hole for inserting a blow pin that blows out compressed air.

As described above, the guide portion 15 extends downward from the exterior member body 11 and is formed continuously along the longitudinal direction L of the exterior member body 11 . On both sides of the guide portion 15 in the longitudinal direction L, as shown in FIGS. A chamfered portion 14 is formed in which the extension length of is gradually reduced.

That is, in the present embodiment, the chamfered portions 14 formed on both sides in the longitudinal direction L of the guide portion 15 extend toward the ends 15e and 15f corresponding to the longitudinal direction L, respectively, so that the lower edge 15d extends from the exterior member body 11. is formed in a straight line inclined toward the lower edge 11d of the .

Here, as described above, the exterior member main body 11 is formed in a bellows shape in which a plurality of concave portions 12 and convex portions 13 are alternately arranged along the longitudinal direction L (FIGS. 3 and 5A). reference). As shown in FIG. 3 , at a portion corresponding to the guide portion 15 in the longitudinal direction L of the cable sheathing member 10 , the plurality of concave portions 12 and the convex portions 13 provided on the sheathing member main body 11 are all aligned with the guide portion 15 . It is formed continuously in the vertical direction of the vehicle. Accordingly, substantially the entire guide portion 15 (the guide surface 15a and the non-guide surface 15b) is also formed in a bellows shape.

The cable sheathing member 10 described above is entirely formed of an elastic member, and is formed in a bellows shape along the longitudinal direction L, including the guide portion 15, as described above. In addition, as described above, the cable armor member 10 is formed in a flat cross section perpendicular to the longitudinal direction L in the same manner as the cable 4 as a flat cable, and is formed to be easily bendable in a substantially horizontal plane (thickness direction T). .

As a result, when the slide door 3 is opened and closed, the cable armor member 10 can bend and deform following the bending deformation of the cable 4 when the slide door 3 is opened and closed.

FIG. 6 is a horizontal cross section schematically showing the cable armor member 10 of this embodiment that deforms between the vehicle body 2 and the sliding door 3 that slides with respect to the vehicle body 2 according to the opening/closing position of the sliding door 3. 6(a) shows the slide door 3 at the fully closed position Pc, FIG. 6(b) shows the slide door 3 at the first half-open position Pm1, and FIG. 6(c) shows the slide door 3 at the second half-open position. Pm2 and FIG. 6(a) show the state where the slide door 3 is positioned at the fully open position Po. 6(a), 6(b), 6(c) and 6(d), the dotted area in the longitudinal direction L of the cable sheathing member 10 indicates the portion provided with the guide portion 15. As shown in FIG.

FIG. 9 is a horizontal cross section schematically showing a conventional cable sheathing member 100 that deforms between the vehicle body 2 and the slide door 3 according to the opening/closing position of the slide door 3. FIG. 6(a), FIG. 9(b) corresponds to FIG. 6(b), and FIG. 9(c) corresponds to FIG. 6(c), respectively.
As the conventional cable armoring member 100 shown in FIGS. 9A, 9B, and 9C, for example, a corrugated tube without the guide portion 15 is adopted. A round electric wire is adopted as a conventional cable (not shown) that is sheathed in the conventional cable sheathing member 100 .

Here, the above-described first half-open position Pm1 of the sliding door 3 indicates an intermediate position of the movable range in which the sliding door 3 slides in the longitudinal direction of the vehicle.
Further, the second half-open position Pm2 of the slide door 3 indicates a position where the slide door 3 is restricted from sliding further toward the rear of the vehicle when the fuel lid (not shown) is open.

More specifically, generally, a fuel lid (not shown) is provided on either the left or right side of the vehicle body at a position behind the door opening 21 . In this example, the fuel lid is provided on the left side portion of the vehicle body 2 (not shown).

When an occupant opens a fuel lid to refuel a vehicle 1 and tries to open the slide door 3 due to carelessness of the occupant, the slide door 3 may interfere with the fuel lid and the fuel hose.

For this reason, in general, when the slide door 3 moves from the fully closed position Pc (see FIG. 6A) to the rear of the vehicle and reaches a predetermined position before interfering with the fuel lid, the slide door A stopper function is provided to forcibly stop 3. The predetermined position before interfering with the fuel lid is the second half-open position Pm2. The second half-open position Pm2 in the present embodiment is set at a position between the first half-open position Pm1 and the fully open position Po in the longitudinal direction of the vehicle.

Next, the operation of the cable sheathing member 10 of the present embodiment, which deforms according to the opening/closing position of the slide door 3, will be described with reference to FIG. will be used for explanation.

When the sliding door 3 is in the fully closed position Pc, the door trim 33 is arranged at a higher position (upper side) than the step surface portion 23b, and extends inward in the vehicle width direction to a substantially middle position in the vehicle width direction of the step surface portion 23b. (See the position of the door trim 33 relative to the step surface portion 23b in FIGS. 6A, 7 and 9A).

In this state, the conventional cable armoring member 100 (conventional cable) is in a state in which substantially the entire length in the longitudinal direction L thereof runs over the step surface portion 23b as shown in FIG. 9(a). That is, the conventional cable sheathing member 100 (conventional cable) intrudes inward in the vehicle width direction from the vehicle width direction outer end 23bb of the step surface portion 23b, and is arranged at the step surface portion 23b and at a position higher than the step surface portion 23b. It is arranged in the space between the door trim 33 (see FIG. 9(a)).

Further, as shown in FIG. 9(a), the conventional cable sheathing member 100 extends further inward in the vehicle width direction (inside the vehicle interior) than the door trim 33 in a state where the middle portion in the longitudinal direction L rides on the step surface portion 23b. It may stick out. When the slide door 3 is in the fully closed position Pc, the overhanging portion 100a (see FIG. 9(a)) may be visually recognized by passengers in the vehicle interior. There is concern that the

As shown in FIG. 9(b), when the sliding door 3 is slid rearward from the fully closed position Pc to open the door opening 21, the conventional cable sheathing member 100 has the sliding door 3 at the fully closed position. As compared with the case of Pc (see FIG. 9(a)), an extra length portion is gradually generated between the vehicle body 2 and the slide door 3. As shown in FIG.

The conventional cable sheathing member 100 (conventional cable) has a U-shaped folded portion 180 formed in the middle in the longitudinal direction L so as to bulge forward of the vehicle in a plan view so as to absorb the extra length. (See FIG. 9(b)).

When the slide door 3 is in the first half-open position Pm1, as shown in FIG. 9(b), the conventional cable armor member 100 has a stepped portion 190 extending in the longitudinal direction L of the folded portion 180 toward the passenger compartment. It intrudes into the inside of the vehicle body 2 by riding on the surface portion 23b.

As a result, the occupant may interfere with the conventional cable armor member 100 (conventional cable) that has run on the step surface portion 23b when getting in and out of the passenger compartment.

Specifically, when the sliding door 3 is in such a first half-open position Pm1 (see FIG. 9B), the area where the overhanging portion 190 of the conventional cable sheathing member 100 toward the passenger compartment rides on the step surface portion 23b. corresponds to a portion where the passenger steps on the step surface portion 23b when the passenger gets on or off the second row of seats (not shown) provided in the passenger compartment.

Therefore, when the slide door 3 is in the first half-open position Pm1, the occupant may step on the conventional cable armor member 100 running on the step surface 23b when getting on or off the second row seat, which is not preferable.

Further, as the slide door 3 is further opened (that is, as the slide door 3 slides toward the rear of the vehicle), the extra length of the cable armor member 100 (conventional cable) becomes longer. Along with this, the folded portion 18 gradually increases in size and moves toward the rear of the vehicle.

Therefore, when the sliding door 3 is in the second half-open position Pm2 shown in FIG. Compared to the case of the first half-open position Pm1 shown in 9(b), the vehicle body 2 penetrates inside the vehicle body 2 so as to ride on the step surface portion 23b further.

As a result, there is a risk that the occupant will interfere with the cable 4 that has run over the step surface portion 23b when getting in and out of the passenger compartment.

Specifically, when the slide door 3 is in such a second half-open position Pm2 (see FIG. 9(c)), the area where the conventional cable sheathing member 100 rides on the step surface portion 23b is provided in the vehicle interior. This corresponds to a portion where the passenger steps on the step surface portion 23b when getting on and off the third row seat (not shown).

Therefore, when the slide door 3 is in the second half-open position Pm2, the occupant may step on the conventional cable armor member 100 running on the step surface portion 23b when getting on or off the third row seat, which is not preferable.

On the other hand, in the cable sheathing member 10 of the present embodiment, as shown in FIGS. 1 and 2, the guide portion is located on the side of the vehicle body 2 with respect to the intermediate position 10M in the longitudinal direction L, that is, on the vehicle rear side of the intermediate position 10M. 15 are provided.

With this configuration, as shown in FIGS. 6A and 7, at least the rear portion of the cable armor member 10 (cable 4) in the longitudinal direction L is restricted by the guide portion 15 from riding on the step surface portion 23b. be. On the other hand, although the front part of the cable armor member 10 in the longitudinal direction L rides on the step surface part 23b, the rear part of the cable armor member 10 is restricted by the guide part 15, so that the intrusion into the vehicle interior is generally prevented. is suppressed (see FIG. 6(a)).

As described above, the cable sheathing member 10 does not protrude from the door trim 33 toward the passenger compartment over the entire length in the longitudinal direction L due to the guide portion 15 . That is, the cable armoring member 10 of the present embodiment has an overhanging portion 100a (see FIG. 9A) that projects inward in the vehicle width direction (inside the vehicle) from the door trim 33, like the conventional cable armoring member 100. never.

Therefore, when the slide door 3 is in the fully closed position Pc, the cable armor member 10 (cable 4) running on the step surface portion 23b does not protrude to a position where it can be visually recognized by the occupant in the vehicle interior space, thereby ensuring a good appearance. .

Further, as described above, the guide portion 15 is formed only at the rear portion of the cable sheath member 10 in the longitudinal direction L and is not formed at the front portion. It is allowed to run on the step surface portion 23b within a range where it does not. Here, as described above, the slide door 3 is arranged so as to be fitted into the door opening 21 at the fully closed position Pc (see FIG. 6(a)). Even in that case, the cable sheathing member 10, particularly including the front portion corresponding to the extending portion extending from the door-side mounting portion 6, is placed between the sliding door 3 and the scuff 23 (vehicle body 2). There is no risk of interference with

Further, in the cable sheathing member 10 of the present embodiment, the guide portion 15 is provided on the vehicle body 2 side with respect to the intermediate position 10M in the longitudinal direction L as described above. Therefore, when the slide door 3 is in the first half-open position Pm1 (see FIG. 9(b)), the guide portion 15 is folded back in the longitudinal direction L of the cable sheathing member 10 as shown in FIG. 6(b). In particular, it can be positioned at the overhanging portion 19 toward the vehicle body 2 side of the portion 18 (bending deformation portion). Therefore, even when the sliding door 3 is in the first half-open position Pm1, the guide portion 15 of the present embodiment can restrict the entry of the cable 4 into the vehicle compartment.

Here, in the process in which the slide door 3 slides from the fully closed position Pc to the rear of the vehicle, as described above, the U-shaped folded portion 18 of the cable armor member 10 (cable 4) according to the present embodiment is replaced by the projecting portion 19. moves to the rear of the vehicle following the opening operation of the slide door 3 while maintaining the state of projecting toward the vehicle body 2 side.

On the other hand, in the cable sheathing member 10 of the present embodiment, as described above, the guide portion 15 is formed continuously along the longitudinal direction L at the rear side portion of the sheathing member main body 11 in the longitudinal direction L. there is

That is, the guide portion 15 of this embodiment is formed continuously along the projecting portion 19 that moves rearward of the vehicle following the opening operation of the sliding door 3 moving rearward of the vehicle.

As a result, the guide portion 15 allows the sliding door 3 to move toward the rear of the vehicle not only at the first half-open position Pm1 (see FIG. 6(b)) but also at the second half-open position Pm2 (see FIG. 6(c)). As shown in FIGS. 6(b) and 6(c), the cable sheath member 10 (cable 4) is in contact with the vehicle width direction outer end 23bb (see FIG. 8) of the step surface portion 23b. Intrusion into the room can be regulated.

Further, as shown in FIG. 6(d), the cable sheathing member 10 (cable 4) of the present embodiment is bent in an S shape in plan view when the slide door 3 is at the fully open position Po. At this time, the guide portion 15 can be arranged in front of the folded portion 18 in the longitudinal direction L of the cable sheathing member 10 .

That is, the guide portion 15 can be arranged in a lower portion between the slide door 3 at the fully open position Po and the vehicle body 2 so as to face the front of the vehicle. Thus, the guide part 15 is arranged so as to block the lower part between the slide door 3 and the vehicle body 2 so as not to be visually recognized by passengers getting in and out of the vehicle compartment through the door opening 21 . Therefore, the vehicle 1 of the present embodiment can ensure a good appearance from the perspective of passengers getting in and out of the passenger compartment even when the sliding door 3 is in the fully open position Po.

Moreover, since the cable armor member 10 of the present embodiment is formed thin in the thickness direction T without being bulky corresponding to the cable 4 formed as a flat cable, the appearance of the cable armor member 10 itself can be secured. can be done.

For example, as shown in FIGS. 1, 2, and 6A, the cable sheath member 10 of the present embodiment described above includes a vehicle body 2 and a slide door that opens and closes a door opening 21 while sliding relative to the vehicle body 2. 3, and is covered with a cable 4 that follows the opening/closing operation of the sliding door 3 and deforms into a bent shape according to the opening/closing position of the sliding door 3 (Fig. 4 ( a) (b), FIG. 5(a), FIG. 7, FIG. 8).

Furthermore, as shown in FIGS. 1, 2, 7, and 8, the cable armoring member 10 of this embodiment includes an armoring member main body 11 that is armored along the longitudinal direction L of the cable 4. and a guide portion 15 for restricting an overhanging portion (19) which is deformed so as to overhang toward the vehicle body 2 when the cable 4 is bent and deformed, from entering the inside of the vehicle body 2. - 特許庁

Furthermore, as shown in FIGS. 1 to 3, 4(b), 6(a) to 6(d), 7 and 8, the guide portion 15 is positioned relative to the step surface portion 23b (vehicle body). The guide portion 15 extends downward (at least one of the vertical directions of the vehicle) with respect to the exterior member main body 11 from the outside in the vehicle width direction (outer side of the vehicle body) so as to be able to contact therewith. , is formed continuously along the longitudinal direction L at least at a portion corresponding to the projecting portion 19 .

According to the above configuration, when the cable 4 is deformed following the opening/closing operation of the slide door 3, the projecting portion (19) in the longitudinal direction L of the cable 4 moves sequentially, regardless of the moving position. Intrusion of the projecting portion (19) into the vehicle body (2) can be continuously restricted by the planar guide portion (15) extending along the longitudinal direction (L) of the exterior member body (11).

For example, as shown in FIGS. 1, 2, and 6(a), the guide portion 15 extends in at least a portion of the vehicle body side portion 10B in the longitudinal direction L of the cable armor member 10 (armor body 11). It is formed continuously along L.

According to the above configuration, the slide door 3 is in the middle of opening and closing the slide door 3, such as the first half-open position Pm1 as shown in FIG. 6(b) and the second half-open position Pm2 as shown in FIG. 6(c). A guide portion 15 can be provided on an overhanging portion 19 (the side facing the vehicle body 2 side) that projects toward the vehicle body 2 side when the cable 4 is bent into a folded shape (U-turn shape).

Therefore, the cable 4 can be prevented from entering the inside of the vehicle body 2 by the guide portion 15 while the slide door 3 is being opened or closed.

On the other hand, when the slide door 3 is in the first half-open position Pm1 as shown in FIG. 6(b) and the second half-open position Pm2 as shown in FIG. The guide part 15 is not provided on the side facing the sliding door 3 side when bent and deformed into the folded shape. In this way, the weight of the cable armoring member 10 can be reduced by suppressing the length occupied by the guide portion 15 with respect to the total length of the armoring member main body 11 in the longitudinal direction L.

As shown in FIGS. 4A and 4B, the cable 4 is a flat cable whose length in the vehicle vertical direction (width direction W) is longer than the length in the thickness direction T, and the exterior member main body 11 is , is formed slightly larger than the cable 4 in the thickness direction T and the width direction W (vehicle vertical direction) so as to be able to be armored with respect to the cable 4, and is flattened in the longitudinal direction L including the portion having the guide portion 15 formed into a shape.

According to the above configuration, the armoring member main body 11 is formed in a flat shape like the cable 4 , so that the bending characteristics (bending resistance) of the cable armoring member 10 can have directionality.

That is, since the cable sheathing member 10 is thin in the thickness direction T, it is easily bent and deformed, and even though it is configured to include the guide portion 15, for example, it is easily bent and deformed when viewed from the top of the vehicle body (bending radius is small). (that is, an increase in bending resistance can be suppressed).

Therefore, since the cable armor member 10 can be prevented from projecting toward the vehicle body 2 side, as a result, the cable armor member 10 can be effectively prevented from entering the vehicle compartment by using the guide function of the guide part 15 as well. can do.

On the other hand, since the cable armor member 10 can be made difficult to bend in the vertical direction of the vehicle, it should be difficult to bend downward due to its own weight even though it has a configuration including the guide portion 15 that continuously extends along the longitudinal direction L. can be done.

Further, as shown in FIGS. 1, 2 and 4B, the guide portion 15 is formed to have the same length in the thickness direction T as the exterior member main body 11 .

According to the above configuration, a stepped portion or the like is not formed at the boundary between the guide portion 15 and the exterior member main body 11 in the vertical direction of the vehicle. It is possible to make it flush in the vertical direction of the vehicle up to.

Therefore, when the guide part 15 comes into contact with the vehicle body, the boundary part between the guide part 15 and the exterior member main body 11 does not catch on the vehicle body side, and the guide part 15 can be brought into firm contact with the vehicle body side.

As shown in FIGS. 1 to 4(a) and (b), in the cable armoring member 10 of the present embodiment, the armoring member main body 11 and the guide portion 15 are integrally formed of elastomer resin (single elastic member). ing.

In the cable armoring member of the present invention, the guide portion 15 may be configured as a separate member so that it can be retrofitted to the armoring member main body 11. However, like the cable armoring member 10 of the present embodiment, By adopting a configuration in which the guide portion 15 is integrally formed with a single elastic member, the number of parts can be suppressed and the configuration can be simplified.

Further, according to the above configuration, it is not necessary to retrofit the guide portion 15 to the exterior member main body 11 at the site or the like. In particular, in this embodiment, the guide portion 15 is formed continuously along the longitudinal direction L of the exterior member main body 11 . Therefore, if the guide portion 15 is to be retrofitted to the exterior member main body 11 , it is necessary to attach the guide portion 15 along the longitudinal direction L of the exterior member main body 11 over a plurality of locations. On the other hand, in the present embodiment, as described above, the exterior member body 11 and the guide portion 15 are integrally formed from a single member, so such trouble is not required.

It should be noted that the elastic member is not limited to elastomer resin as in the present embodiment, and can be formed of rubber, for example, as long as it has elasticity that allows bending deformation.

As shown in FIGS. 3, 5A, and 5B, the exterior member main body 11 has a concave portion 12 whose cross section along the longitudinal direction L is concave in the thickness direction T and a convex portion 13 which is convex. , and extend linearly in the vertical direction of the vehicle over substantially the entire exterior member main body 11, and are formed in a bellows shape in which a plurality of them are alternately arranged along the longitudinal direction L. As shown in FIG.

According to the above configuration, since the cable sheathing member 10 is formed in a bellows shape along the longitudinal direction L, bending deformation in the thickness direction T is facilitated (that is, an increase in bending resistance is alleviated) in a plan view of the vehicle body. can be done.

Furthermore, as shown in FIG. 3, the concave portion 12 and the convex portion 13 in the portion corresponding to the guide portion 15 in the longitudinal direction L of the exterior member main body 11 extend substantially to the lower edge 15d of the guide portion 15 in the vertical direction of the vehicle. is formed continuously.

According to the above configuration, the cable sheathing member 10 including the guide portion 15 is formed in a bellows shape along the longitudinal direction L. Therefore, in a plan view of the vehicle body, the cable sheathing member 10 including the guide portion 15 is easily bent (that is, bent). increase in resistance).

Therefore, the cable sheathing member 10 is suppressed from projecting toward the vehicle body 2 during bending deformation, and as a result, it is possible to suppress the cable sheathing member 10 from intruding into the vehicle compartment.

Further, according to the above configuration, since a plurality of projections 13 extending in the vertical direction of the vehicle are arranged along the longitudinal direction L of the guide portion 15 (see FIG. 3), the projections 13 are arranged along the guide portion 15. It can function as a reinforcing rib.

That is, by forming the guide portion 15 in a bellows shape, it is possible to make the guide portion 15 less prone to bending deformation (deflection deformation) in the width direction W.

As a result, when the guide portion 15 comes into contact with the vehicle body 2, for example, a part of the guide portion 15 in the width direction W is bent in the thickness direction T, and the guide portion 15 rides on the step surface portion 23b. can be suppressed.

Therefore, even if the cable armoring member 10 including the guide portion 15 is formed of an elastic member such as an elastomer resin as in the present embodiment, the armoring member body 11 does not intrude further into the vehicle body 2. Thus, the guide portion 15 can be firmly regulated.

As shown in FIGS. 1 to 3, the cable sheathing member 10 of the present embodiment has a downward extension length of at least A chamfered portion 14 is formed which gradually becomes smaller as it approaches the ends 15e and 15f (see FIG. 3) on one side.

Here, if the chamfered portions 14 are not formed on both sides of the guide portion 15 in the longitudinal direction L, the cable sheathing member 10 is formed on both sides of the guide portion 15 in the longitudinal direction L where the guide portion 15 is not provided. is formed stepwise along the longitudinal direction L. That is, the shape of the lower end of the cable sheathing member 10 extending along the longitudinal direction L abruptly changes in the vertical direction of the vehicle at the boundary.

As a result, when the cable armor member 10 is bent and deformed, the bending stress is concentrated on the boundary portions located on both sides of the guide portion 15 in the longitudinal direction L, and as a result, the cable armor member 10 may be easily bent and deformed at the boundary portions. There is

In contrast, according to the cable sheathing member 10 of the present embodiment, since the chamfered portions 14 are formed on both sides of the guide portion 15 in the longitudinal direction L, when the cable sheathing member 10 is bent and deformed, Concentration of bending stress can be suppressed.

Therefore, the cable sheathing member 10 of the present embodiment can be gently bent and deformed in plan view of the vehicle body without being locally bent and deformed even at the boundary portions on both sides in the longitudinal direction L of the guide portion 15 during bending deformation. can be done.

As shown in FIGS. 4(a), 4(b), and 5(a), the exterior member main body 11 of the present embodiment is provided with a housing space 16 for housing the cable 4 therein, as shown in FIG. 4(a). Thus, an opening 17 for taking the cable 4 in and out of the housing space 16 is formed in the lower edge 11d of the exterior member main body 11 in a slit shape extending along the longitudinal direction L in the thickness direction T (vehicle vertical direction). ing.

According to the above configuration, when the guide portion 15 contacts the vehicle body 2 (the vehicle width direction outer end 23bb of the step surface portion 23b) (see FIGS. 7 and 8), the guide portion 15 receives a reaction force from the vehicle body 2 side. can act in the direction in which the opening 17 closes (outside in the vehicle width direction).

Thereby, when the guide part 15 comes into contact with the vehicle body 2, it is possible to prevent the cable 4 housed in the housing space 16 from being exposed to the outside or escaped due to the opening part 17 being carelessly opened.

Here, when the cable armor member 10 is bent and deformed in plan view of the vehicle body due to the opening and closing of the slide door 3, the guide surface 15a side (outer peripheral side) of the guide portion 15 is deformed due to the thickness of the guide portion 15. and a portion on the non-guide surface 15b side (inner peripheral side). If the guide portion 15 is integrally formed without being divided in the thickness direction T, the bending deformation of the guide portion 15 may occur due to the path difference occurring between one side and the other side in the thickness direction T. internal stress is generated at the core, increasing the bending resistance (that is, making it difficult to bend).

On the other hand, as shown in FIG. 4B, the opening 17 passes through the inside of the guide portion 15 in the thickness direction T so as to divide the guide portion 15 into one side and the other side in the thickness direction T. is formed in the shape of a slit extending in the vertical direction of the vehicle.

That is, since the guide portion 15 of the present embodiment is formed so as to be divided into one side and the other side in the thickness direction T along the longitudinal direction L by the opening portion 17, the bending deformation of the guide portion 15 in plan view of the vehicle body It is possible to suppress an increase in bending resistance over time.

As shown in FIG. 8, the lower edge 11d of the exterior member main body 11 is arranged at a position higher than a step surface portion 23b provided on the vehicle body 2 as a footstool when a passenger gets in and out of the vehicle interior through the door opening 21. .

On the other hand, as shown in FIGS. 7 and 8, the guide portion 15 extends downward from the exterior member main body 11 so that the lower edge 15d of the guide portion 15 is arranged at a position lower than the step surface portion 23b. It is

According to the above configuration, even when the cable 4 attempts to enter the inside of the vehicle body 2 during bending deformation, the exterior member main body 11 provided at a position higher than the step surface portion 23b is positioned above the step surface portion 23b in the vehicle width direction. Damage due to interference with the outer end 23bb can be prevented.

On the other hand, since the lower edge 15d of the guide portion 15 is provided at a position lower than the step surface portion 23b, the overhanging portion 19 of the cable sheathing member 10 extending toward the inside of the vehicle body 2 tends to enter the vehicle body 2 toward the inside. At this time, the step surface portion 23b is reliably brought into contact with the vehicle width direction outer end 23bb of the step surface portion 23b. As a result, the cable sheathing member 10 of this embodiment can be regulated by the guide portion 15 so as not to enter the vehicle body 2 .

This invention is not limited to only the configurations of the examples described above, but can be formed in various embodiments.

For example, the opening 17 is not limited to being formed at an intermediate position in the thickness direction T of the lower portion of the exterior member main body 11 as described above, and may be formed at another portion in the thickness direction T of the lower portion of the exterior member main body 11. good.

For example, although not shown, a portion on the side of the guide surface 15a (peripheral side) in the thickness direction T of the guide portion 15 (the edge portion 17a on one side of the opening portion 17 (see FIG. 4B)) A configuration may be adopted in which the portion is formed to be longer in the thickness direction T than the portion on the side of the guide surface 15b (inner peripheral side) (the edge portion 17b on the other side of the opening portion 17 (see the figure)).

According to the above configuration, when the guide portion 15 comes into contact with the vehicle body 2, the reaction force that the guide portion 15 receives from the vehicle body 2 side is reduced from the portion on the non-guide surface 15b side in the thickness direction T of the guide portion 15. can be firmly received by the portion on the side of the guide surface 15a that is long in the thickness direction T.

As a result, when the guide portion 15 comes into contact with the vehicle body 2, it is possible to prevent the cable accommodated in the accommodation space from being exposed or escaped due to the opening portion 17 being carelessly opened.

In the cable sheathing member of the present invention, although not shown, the sheathing member body 11 is provided with, for example, a plurality of guide portions protruding downward from the lower edge 11d of the sheathing member body 11 along the longitudinal direction L. configuration may be employed.
