Description

  The present invention relates to a clamp structure for a rope for a motorcycle, specifically, a structure for clamping a main brake hose, a sub brake hose and a sensor cable for a front wheel of a motorcycle.

  2. Description of the Related Art Conventionally, there has been known a motorcycle provided with a pair of brake discs on both sides of a front wheel and provided with a brake caliper for braking the brake disc. One brake caliper is connected to a master cylinder, which is a hydraulic pressure generating mechanism, via a main hose, and both brake calipers are connected by a sub brake hose arranged so as to straddle the front wheels. The hydraulic pressure generated by the master cylinder is transmitted to one brake caliper by the main brake hose and is transmitted to the other brake caliper by the sub brake hose. The front wheel is covered with a fender that receives mud splash, the main brake hose is clamped by a clamp member provided on the fender, and the auxiliary brake hose is clamped in a groove formed on the fender (see Patent Document 1).

JP-A-9-150769

In the conventional configuration, the main brake hose and the auxiliary brake hose are separately clamped on the fender, so that the number of locations to be clamped increases. As a result, workability when clamping both brake hoses is deteriorated. Also, depending on the position of the clamp location, the main brake hose and the sub brake hose may repeatedly approach and separate from each other when steering the front wheel, and both brake hoses may be damaged by friction caused by the contact of both brake hoses. There is also sex.
An object of the present invention is to reduce the number of clamping points for clamping both brake hoses, and to prevent the brake hoses from repeatedly approaching and separating from each other.

  The clamp structure for a motorcycle cord according to the present invention holds a main hose that connects one caliper and a master cylinder or a hydraulic unit among a pair of brake calipers arranged on both sides of a wheel by a clamp member. The one caliper and the other caliper located on the opposite side of the wheel with respect to the caliper are connected by a secondary hose, and the clamp member is attached to a front fork that supports the wheel. The clamp member is disposed on a fender that covers a wheel, and the clamp member is integrally formed with a first holding portion that holds the main hose and a second holding portion that holds the sub hose with a space from the main hose. I have.

  In the two-wheeled vehicle clamp structure according to the present invention, since both the main hose and the sub hose can be held by one clamp member, the number of parts to be clamped or the number of parts to be clamped can be reduced. Can be reduced. Furthermore, since the main hose and the sub hose are held at a distance from each other, it is possible to prevent the two hoses from repeatedly approaching and separating from each other.

(First embodiment)
Hereinafter, a vehicle according to an embodiment of the present invention, specifically, a motorcycle will be described with reference to the drawings. In the following description, the same or corresponding elements are denoted by the same reference symbols throughout all the drawings, and redundant description is omitted. In the following description, the left-right direction is based on the direction viewed from the driver riding the motorcycle. The inside and outside are based on the axle direction.
FIG. 1 is a side view of a motorcycle 1 according to an embodiment of the present invention, in which a main brake hose and a sub brake hose described later are omitted. As shown in FIG. 1, the body frame of the motorcycle 1 includes a main frame 10 that is inclined downward and extending from the front to the rear, and a head pipe that extends obliquely downward from the front end of the main frame 10 toward the front. 100, an upper bracket 12 disposed between the upper ends of the head pipe 100, and an under bracket 18 attached to the head pipe 100 at a position below the upper bracket 12. A front portion of the head pipe 100 is covered with a cowling 200. A handle 13 protruding from the left and right is attached from the upper bracket 12. A pair of left and right front forks 11 extend downward from the under bracket 18, and the front forks 11 rotatably support a front wheel 90 by an axle 93 provided at a lower end portion thereof. A fender 3 that receives mud splashing and water splashing by the front wheel 90 is attached to the front fork 11 so as to cover the front wheel 90. Since the front fork 11 extends and contracts up and down as is well known in order to secure the cushion stroke of the front wheel 90, the fender 3 also moves up and down with the front fork 11.

  A seat rail 15 is connected to the rear portion of the main frame 10, and a driver's seat 16 and a passenger's seat 17 are supported on the seat rail 15 across the front and rear. A swing arm bracket 14 extending downward is provided at the lower rear end of the main frame 10, and a front end portion of the swing arm 6 is swingably supported by the swing arm bracket 14 via a pivot shaft 61. A rear wheel 9 is rotatably supported by an axle 93 at the rear end of the swing arm 6. In front of the swing arm 6, an engine E is supported on the lower part of the main frame 10, and the rear wheel 9 is driven by the engine E via a chain 97. An exhaust device 99 having a muffler 98 is connected to the engine E.

FIG. 2 is a front view of the motorcycle 1 shown in FIG. 1, with the front wheel 90 and the fender 3 broken away. Upper ends of the pair of front forks 11 are supported by the upper bracket 12 and the under bracket 18, and a steering shaft 19 that couples the brackets 12 and 18 is rotatably fitted in the head pipe 100. Thus, when the handle 13 is steered left and right, the front wheel 90 is steered left and right via the brackets 12 and 18 and the front fork 11. As is well known, the front wheel 90 includes a front wheel 91 and a rubber tire 92 surrounding the front wheel 91, and brake discs 50 are fixed coaxially to the axle 93 on both sides of the front wheel 91. A vehicle speed detection disk 40 is mounted coaxially with the axle 93 so as to face the left brake disk 50.
Each front fork 11 is provided with brake calipers 51 and 52 so as to face each brake disc 50. Each of the brake calipers 51 and 52 brakes the rotation of the rear wheel 9 by sandwiching the opposing brake disc 50 from both sides with a built-in brake pad (not shown). For convenience of explanation, the left brake caliper is referred to as a first brake caliper 51, and the right brake caliper is referred to as a second brake caliper 52. A master cylinder 58 that houses brake oil and functions as a hydraulic pressure generating mechanism is attached to the right side of the handle 13. The master cylinder 58 and the first brake caliper 51 are connected by a main brake hose 5, and brake oil from the master cylinder 58 is supplied to the first brake caliper 51 via the main brake hose 5.

  The main brake hose 5 extends downward from the master cylinder 58 through one side, that is, the right front fork 11, and is held by the holding member 8 provided at the lower end of the under bracket 18, and then the other, ie, the left front fork. It extends obliquely downward toward the fork 11 and reaches the first brake caliper 51. In other words, the master cylinder 58 supplies brake oil to the first brake caliper 51 located on the opposite left and right sides with the head pipe 100 interposed therebetween. Both brake calipers 51, 52 are connected by a sub brake hose 55 provided so as to straddle the fender 3, and the brake oil supplied to the first brake caliper 51 passes through the sub brake hose 55 to the second brake caliper 52. Also supplied. The main brake hose 5 does not connect the master cylinder 58 and the second brake caliper 52 located on the left and right sides of the master cylinder 58, but the master cylinder 58 and the first brake located on opposite sides of the master cylinder 58. The reason why the caliper 51 is connected will be described later.

  A vehicle speed sensor 42 is provided on the left front fork 11 so as to face the vehicle speed detection disk 40, and one end of the sensor cable 4 is connected to the vehicle speed sensor 42. The sensor cable 4 extends upward along the left front fork 11 and is then connected at the other end to an engine control unit (ECU) (not shown). The main brake hose 5 and the sub brake hose 55 are provided with a larger diameter than the sensor cable 4. The sensor cable 4, the main brake hose 5 and the auxiliary brake hose 55 correspond to the “two-wheel vehicle cord” of the present invention. The main brake hose 5 corresponds to the “main hose” of the present invention, the sub brake hose 55 corresponds to the “sub hose” of the present invention, and the front fork 11 corresponds to the “wheel support portion” of the present invention.

3 is a perspective view showing the left side of the front wheel 90 of FIG. 2, and FIG. 4 is an enlarged view of the main part of FIG. A number of through holes 41 are formed in the vehicle speed detection disk 40. The vehicle speed sensor 42 detects the number of through holes 41 passing through the vehicle speed sensor 42 per unit time as data, and transmits the data to the ECU via the sensor cable 4. The ECU obtains the rotational speed of the front wheel 90 from the data and displays the traveling speed of the motorcycle 1 on a speed meter (not shown) provided near the handle 13. Further, the ECU detects the idling of the wheel by comparing the rotational speed of the front wheel 90 with the rotational speed of the rear wheel 9. That is, the vehicle speed sensor 42 constitutes a known traction control system. The vehicle speed sensor 42 is located in front of the first brake caliper 51.
As shown in FIG. 4, a clamp member 2 that clamps the main brake hose 5 and the sub brake hose 55 is provided on the left side surface of the fender 3 and behind the front fork 11. The clamp member 2 is formed by bending a metal plate, and includes a first holding part 21 for clamping the main brake hose 5, a second holding part 22 for clamping the auxiliary brake hose 55, and both holding parts 21, 22. Are integrally provided with a flat plate-like connecting plate 20 (see FIG. 4). The sensor cable 4 and the main brake hose 5 are held by a plate-like elastic support member 7 positioned above the first holding portion 21. The elastic support member 7 is formed with a first notch 70 in which the sensor cable 4 is fitted, and a second notch 71 in which the main brake hose 5 is fitted. The first notch 70 is in front of the second notch 71. Located (see FIG. 6).

  The connecting plate 20 has two through holes 23, and the fender 3 has through holes (not shown) corresponding to the through holes 23. The clamp member 2 is fixed to the left side surface of the fender 3 by two rivets 28 that pass through the through hole 23 and the through hole. That is, the rivet 28 corresponds to the “fixing tool” of the present invention. Both holding portions 21 and 22 do not cover the connecting plate 20 and do not obstruct the insertion of the rivet 28 into the through hole 23. Further, since the first notch 70 is positioned in front of the second notch 71, the sensor cable 4 extending from the vehicle speed sensor 42 positioned in front of the first brake caliper 51 reaches the elastic support member 7. The main brake hose 5 does not intersect. The number of through holes 23 and rivets 28 is not limited to two. Further, since the connecting plate 20 has a flat plate shape, the left side portion of the fender 3 facing the connecting plate 20 needs to be formed flat. In view of the strength for holding the clamp member 2, the left side surface of the fender 3 is preferably formed thick.

  As shown in FIG. 4, the second holding part 22 is located behind and below the first holding part 21. The first holding part 21 clamps the main brake hose 5, the second holding part 22 clamps the auxiliary brake hose 55, and the fender 3 is bent obliquely downward from a position where the front fork 11 overlaps the side view. Since the auxiliary brake hose 55 is provided so as to straddle the fender 3, the auxiliary brake hose 55 is provided by providing the second holding part 22 behind and lower than the first holding part 21 along the bending direction of the fender 3. The length can be shortened. In particular, the angle θ2 that the auxiliary brake hose 55 clamped to the second holding part 22 makes with the vertical line is smaller than the angle θ1 that the main brake hose 5 clamped to the first holding part 21 makes to the vertical line. That is, the auxiliary brake hose 55 is bent in an arc shape at a position on the fender 3 near the second holding portion 22 and heads toward the second brake caliper 52. Accordingly, the curvature of the auxiliary brake hose 55 straddling the fender 3 is increased, and the length of the auxiliary brake hose 55 from the second holding portion 22 to the upper surface of the fender 3 is shortened.

The fender 3 to which the clamp member 2 is attached is attached to the front fork 11 as described above, and the first brake caliper 51 is attached to the front fork 11. Therefore, the length of the main brake hose 5 from the clamp member 2 to the first brake caliper 51 does not change even if the front fork 11 is extended or contracted. Thereby, even if the front fork 11 expands and contracts, the load applied to the main brake hose 5 is reduced.
FIG. 5 is a sectional view of the fender 3 shown in FIG. 4 taken along the plane including the VV line and viewed from the direction of the arrow. For reasons of external design, the rubber tire 92 is provided with a larger gap S2 with the fender 3 side surface than a gap S1 with the fender 3 lower surface. Therefore, by attaching the clamp member 2 to the side surface of the fender 3, a part of the rivet 28 protruding to the back side of the fender 3 and the rubber tire 92 are provided with a wide space, and the part of the rivet 28 and the rubber tire 92 can interfere with each other. Avoiding sex.

Since the motorcycle 1 needs to tilt the vehicle body when turning, the ground contact area of the front wheel 90 is small. Therefore, the rubber tire 92 is formed in a cross-sectional shape close to an ellipse. The clamp member 2 is provided at a position where the side surface of the fender 3 and the outer surface of the rubber tire 92 are close to each other, preferably the closest position, and prevents the main brake hose 5 and the sub brake hose 55 from contacting the front wheel 90. Yes.
As shown in FIG. 5, on the fender 3, the attachment location 30 of the clamp member 2 is formed thicker than other locations on the fender 3, and is convex outward. Further, the surface 31 that contacts the clamp member 2 is formed substantially flat. Thereby, the clamp member 2 can be attached stably.

  FIG. 6 is a perspective view of the clamp member 2 and the elastic support member 7. The first holding part 21 and the second holding part 22 are provided so as to be displaced vertically, and the horizontal cross section is formed in an arc shape. A first opening 24 through which the main brake hose 5 passes is provided at the rear part of the first holding part 21, and a second opening 25 through which the auxiliary brake hose 55 passes is provided at the front part of the second holding part 22. Yes. That is, the main brake hose 5 and the sub brake hose 55 are inserted into the holding portions 21 and 22 from opposite directions. The first opening 24 faces the auxiliary brake hose 55, and the second opening 25 faces the main brake hose 5. The first opening 24 is formed with a width slightly smaller than the diameter of the main brake hose 5, and the second opening 25 is formed with a width slightly smaller than the diameter of the sub brake hose 55.

(Attaching the brake hose and sensor cable)
In order to attach both the brake hoses 5 and 55 and the sensor cable 4 to the clamp member 2, the following procedure is used. First, the clamp member 2 is attached to the fender 3 with the rivet 28. The tip of the rivet 28 that has passed through the through hole 23 and the through hole is crimped to the fender 3, and the clamp member 2 is fixed to the fender 3. Next, the main brake hose 5 is inserted into the first opening 24. Since the first opening 24 is smaller than the diameter of the main brake hose 5, the main brake hose 5 is elastically deformed so as to be contracted, and is inserted into the first holding portion 21 to return elastically. Next, the auxiliary brake hose 55 is inserted into the second opening 25. Since the second opening 25 is smaller than the diameter of the auxiliary brake hose 55, the auxiliary brake hose 55 is elastically deformed so as to be contracted, and is inserted into the second holding portion 22 to be elastically restored. Both brake hoses 5 and 55 are clamped to the clamp member 2.

Thereafter, the sensor cable 4 is fitted into the first cutout 70 of the elastic support member 7, and the main brake hose 5 is fitted into the second cutout 71 of the elastic support member 7. Both brake hoses 5, 55 have a large diameter and are highly rigid because they need to withstand the hydraulic pressure of the brake oil. Therefore, the brake hose 5 and 55 with high rigidity are clamped to the clamp member 2 first, and the workability of attaching the sensor cable 4 to the elastic support member 7 is improved. The main brake hose 5 may be attached to the first holding part 21 after the auxiliary brake hose 55 is attached to the second holding part 22 first.
Instead of the elastic support member 7, the main brake hose 5 and the sensor cable 4 may be fixed with another member above the clamp member 2.

  In this embodiment, the master cylinder 58 attached to the handle 13 and the main brake hose 5 are connected (see FIG. 2), and the main brake hose 5 extends from the front of the front fork 11 to the rear. On the other hand, the main brake hose 5 may be connected to a hydraulic unit (not shown) provided inside the vehicle body. In this case, the main brake hose 5 is folded into a U shape from the rear of the front fork 11 and fixed to the fender 3. Even in this case, the curvature of the main brake hose 5 can be increased by holding the main brake hose 5 while the first holding portion 21 is inclined downward toward the rear. The main brake hose 5 may be attached to the one of the two holding portions 21 and 22 that has a larger curvature. It may be supported. By doing in this way, the component, that is, the clamp member 2 is made common in the motorcycle 1 in which the main brake hose 5 is connected to the master cylinder 58 and the motorcycle 1 in which the main brake hose 5 is connected to the hydraulic unit. The curvature of the main brake hose 5 can be increased as much as possible.

(Second Embodiment)
FIG. 7 is a perspective view of the clamp member 102 according to the present embodiment. In the first embodiment, both the brake hoses 5 and 55 are clamped by the clamp member 2, and the sensor cable 4 is clamped by the elastic support member 7. However, instead of this, both the brake hoses 5 and 55 and the sensor cable 4 may be held by one clamp member 102 as shown in FIG. In this case, a third holding portion 26 that clamps the sensor cable 4 is formed on the back side, that is, the front side of the first holding portion 21. Since the third holding portion 26 is located in front of the first holding portion 21, the sensor cable 4 extending from the vehicle speed sensor 42 located in front of the first brake caliper 51 extends to the clamp member 102 until the main brake. Do not cross the hose 5.

  The first holding unit 21, the second holding unit 22, and the third holding unit 26 shown in FIG. 7 are each formed in an arc shape in cross section, and the first holding unit 21 and the third holding unit 26 are communicated with each other. The third holding part 26 is formed with a smaller diameter than the first holding part 21 so that the sensor cable 4 can be fitted. A first opening 24 through which the main brake hose 5 and the sensor cable 4 pass is provided at the rear part of the first holding part 21, and a second opening 25 through which the auxiliary brake hose 55 passes at the front part of the second holding part 22. Is provided. That is, the insertion direction of the sensor cable 4 and the main brake hose 5 into the holding portions 26 and 21 is opposite to the insertion direction of the sub brake hose 55 into the second holding portion 22. The third holding portion 26 may be integrated with the clamp member 102 or may be a separate body.

In order to attach both the brake hoses 5 and 55 and the sensor cable 4 to the clamp member 102, the following procedure is performed. First, the clamp member 102 is attached to the fender 3 with the rivet 28. Next, the sensor cable 4 is inserted into the third holding part 26 through the first opening 24 and the first holding part 21. Since the main brake hose 5 is fitted to the first holding part 21 and the sensor cable 4 has a smaller diameter than the main brake hose 5, the sensor cable 4 can pass through the first holding part 21 smoothly. Thereafter, the main brake hose 5 is inserted into the first opening 24. Since the first opening 24 is smaller than the diameter of the main brake hose 5, the main brake hose 5 is elastically deformed so as to be contracted, and is inserted into the first holding portion 21 to return elastically.
If the large-diameter first holding portion 21 is located on the back side of the small-diameter third holding portion 26, it becomes difficult for the main brake hose 5 to pass through the third holding portion 26. Accordingly, the third holding unit 26 is provided on the back side of the first holding unit 21.

Next, the auxiliary brake hose 55 is inserted into the second opening 25. Since the second opening 25 is smaller than the diameter of the auxiliary brake hose 55, the auxiliary brake hose 55 is elastically deformed so as to be contracted, and is inserted into the second holding portion 22 to be elastically restored. The main brake hose 5 may be attached to the first holding part 21 after the auxiliary brake hose 55 is attached to the second holding part 22.
In the above embodiment, the master cylinder 58 and the first brake caliper 51 connected to the master cylinder 58 via the main brake hose 5 are provided on the left and right sides with the head pipe 100 interposed therebetween. On the other hand, it is conceivable that the master cylinder 58 and the first brake caliper 51 are provided on the same side of the head pipe 100 and the main brake hose 5 is held by the holding member 8 of the under bracket 18. Thereby, the main brake hose 5 becomes short. However, since the first brake caliper 51 is attached to the front fork 11, it moves up and down together with the front fork 11. Accordingly, in the state where the front fork 11 is contracted most, the main brake hose 5 has an arcuate bent portion below the holding member 8 (see FIGS. 2 and 3). When the main brake hose 5 is short, the degree of bending of the bent portion increases, resulting in a burden on the main brake hose 5. Accordingly, the master cylinder 58 and the first brake caliper 51 are provided on the opposite left and right sides with the head pipe 100 interposed therebetween, the main brake hose 5 is set longer, and added to the main brake hose 5 when the front fork 11 moves up and down. To reduce the burden.

(Brake hose and sensor cable retention effect)
Since the main brake hose 5 and the auxiliary brake hose 55 can be held by one clamp member 2, the number of parts can be reduced as compared with the case where the main brake hose 5 and the auxiliary brake hose 55 are held by separate parts. Can do. In particular, if the sensor cable 4 is also held by the clamp member, the effect is even higher. Further, since the main brake hose 5 and the auxiliary brake hose 55 are held at a distance from each other by the clamp member 2, it is possible to prevent the brake hoses 5 and 55 from repeatedly contacting or separating.
The fender 3 to which the clamp member 2 is attached is attached to a front fork 11 provided with a first brake caliper 51. Thereby, even if the front fork 11 expands and contracts, since the length of the main brake hose 5 from the clamp member 2 to the first brake caliper 51 does not change, the load applied to the main brake hose 5 is reduced.

(Third embodiment)
FIG. 8 is a perspective view showing an auxiliary brake hose 55 according to the third embodiment. A rubber grommet 47 is fitted to the sub brake hose 55, and the grommet 47 is configured by providing a casing 49 at both ends of a cylindrical body 48 fitted to the second holding portion 22. In a state where the cylinder body 48 that encloses the auxiliary brake hose 55 passes through the second opening 25 and is clamped by the second holding part 22, the housing 49 comes into contact with the upper and lower end surfaces of the second holding part 22, thereby The hose 55 is prevented from moving back and forth. Accordingly, it is possible to prevent the auxiliary brake hose 55 from being worn by the auxiliary brake hose 55 being rubbed directly with the second holding portion 22. Note that the grommet 47 may be fitted and clamped to the main brake hose 5 and the sensor cable 4.

(Fourth embodiment)
FIG. 9 is a side view showing a main brake hose and a sub brake hose according to the fourth embodiment, and FIG. 10 is a perspective view of the same. In the present embodiment, the auxiliary brake hose 55 is attached to the first holding part 21, and the main brake hose 5 is attached to the second holding part 22. That is, the auxiliary brake hose 55 is positioned in front of the main brake hose 5. The first holding unit 21 holds the auxiliary brake hose 55 in a state where it is inclined downward toward the rear. In other words, the auxiliary brake hose 55 in the first holding portion 21 is inclined downwardly away from the front fork 11 or the vertical line. Similarly, the main brake hose 5 is inclined downwardly away from the front fork 11 or the vertical line in the second holding portion 22.
As described above, the plurality of clamp members 2 are attached to the fender 3 by two rivets 28 in FIG. 9, and both the rivets 28 are positioned vertically along the radial direction of the wheel 90. That is, the rivet 28 is located between the front and rear of both the hoses 5 and 55, and the front-rear distance necessary for providing both the rivets 28 can be narrow. Thereby, while being able to arrange | position both the hoses 5 and 55 approaching back and forth, the rigidity which the clamp member 2 supports both the hoses 5 and 55 can be ensured.
Both brake hoses 5 and 55 are fitted into the grommet 47, and the cylindrical body 48 of the grommet 4 is attached to the second holding part 22 and the first holding part 21, respectively. The casing 49 of the grommet 47 is positioned up and down so as to sandwich the holding portions 22 and 21, thereby restricting the movement of both the brake hoses 5 and 55 along the longitudinal direction.

  In the present embodiment, the first curved portion 75 a on one end side of the S-shaped stopper 75 in plan view is attached so as to fit on the peripheral surface of the second holding portion 22, and the other end portion of the stopper 75 is attached. The sensor cable 4 is fitted and held inside the second bending portion 75b. The first bending portion 75a has a larger radius of curvature than the second bending portion 75b. The stopper 75 is formed by bending a metal wire, and the first curved portion 75a is fixed to the peripheral surface of the second holding portion 22 by welding. Thereby, the sensor cable 4 is fixed to the clamp member 2. In addition, the fixing method of the stopper 75 is not limited to welding. Further, a protector member (not shown) may be attached to the surface of the sensor cable 4 and fitted to the stopper 75.

The first brake caliper 51 (see FIG. 5) is located from the front of the front fork 11 to the rear of the front fork 11 by disposing the main brake hose 5 in front of the sub brake hose 55 and clamping it diagonally downward toward the rear. 3), the curvature of the main brake hose 5 can be increased. Thus, when a shock is applied to the front wheel 90, the amount of bending of the main brake hose 5 is reduced even when the axle 93 (see FIG. 2) moves upward toward the under bracket 18 in order to mitigate the shock. The rate at which becomes smaller can be suppressed. Further, the secondary brake hose 55 can also be increased in curvature by inclining obliquely on the side of the fender 3. Furthermore, the sub brake hose 55 is arranged behind the main brake hose 5 so that the main brake hose 5 can be arranged as far back as possible. Accordingly, the curvature of the main brake hose 5 can be further increased, and the auxiliary brake hose 55 can be disposed on the fender 3 without greatly extending the fender 3 rearward.

In the motorcycle according to the present embodiment, a motorcycle using gasoline as fuel is assumed, but the technical contents of the present embodiment can be applied to, for example, an electric motorcycle. A hub steer structure can be used instead of the front fork.

Accordingly, the foregoing description should be construed as illustrative only and is provided for the purpose of teaching those skilled in the art one mode of carrying out the invention. The details of the structure and / or function can be substantially changed without departing from the spirit of the invention.

  The present invention is useful when used in a motorcycle in which a cable body such as a brake hose or a sensor cable is wired.
