The second linear body holding portion 14 has one end 1 of the arc-shaped portion 12.
2a is the other end 1 of the arcuate portion 11 of the first linear body holding portion 13.
It is integrally connected to 1b.

One end 11a and the other end 11b of the arcuate portion 11 of the first linear member holding portion 13 are separated from each other so that the first cable 5 can be inserted into and removed from the arcuate portion 11. The opening 13a is formed. Similarly, the second linear body holding portion 1
The one end 12a and the other end 12b of the four arcuate portions 12 are also separated from each other to form an opening 14a for inserting and removing the second cable 6 into the arcuate portion 12. Further, the arcuate portions 11, 12 of the first and second linear body holding portions 13, 14

When set inside 2, the arcuate portions 11 and 12 elastically return to narrow the widths W ₁ and W _{2 of the} openings 13a and 14a. At this time, since the widths W ₁ and W ₂ of the openings 13a and 14a are smaller than the inner diameters D ₁ and D _{2 of the} arcuate portions 11 and 12 as described above, the first and second cables 5 and 6 are not formed. Is held by being surrounded by the inner peripheral surfaces of the arcuate portions 11 and 12, and the cables 5 and 6 are connected to the openings 13a and 14 respectively.
It is prevented from coming off to the outside of each arcuate portion 11, 12 through a.

As described above, the first and second cables 5, 6
Can be fixed to the head cover 2a of the engine 2 while being held by the linear body holding clamp 8, so that the cables 5 and 6 can be prevented from interfering with other elements. Moreover, since the two cables 5 and 6 can be held by the one clamp 8 and fixed to each other, it is not necessary to prepare one clamp for each cable 5 and 6 as in the conventional case, and the total cost thereof can be reduced. Can be lowered.

In the embodiment shown in FIGS. 2 and 3, two linear body holding portions are provided, but the number is set to three or more, and the linear body such as a cable is held by that number. You can also FIG. 4 shows four linear body holding portions 13, 14, 11
An example of a clamp 8 having 3,114 is shown. The third linear body holding portion 113 shown here is the first linear body holding portion 1
3, the one end 111a of the arcuate portion 111 is integrally connected to the other end 12b of the arcuate portion 12 of the second linear body holding portion 14. Further, the fourth linear body holding portion 114 also has exactly the same form as the second linear body holding portion 14, and one end 112a of the arcuate portion 112 has a circle of the third linear body holding portion 113. It is integrally connected to the other end 111b of the arcuate portion 111. The opening 113a of the third linear body holding portion 113 is the opening 13a of the first linear body holding portion 13.
The opening 114a of the fourth linear body holding portion 114 faces the same direction as the opening direction 14a of the second linear body holding portion 14. Third and fourth linear body holding portions 11
3, 114 are third and fourth as shown in FIG. 4, respectively.
The cables 105 and 106 can be held. It is possible to provide n (n ≧ 2) linear body holding portions in exactly the same manner. As described above, the clamp according to the present invention has at least two first and second linear body holding portions that surround the linear body and have arcuate portions that hold the linear body. Has become. Other configurations in FIG. 4 are the same as those shown in FIGS. 2 and 3.

In FIG. 5, the tip end side portion 10c of the intermediate portion 10 integrally formed with the base portion 9 fixed to the mounting portion composed of the head cover 2a of the engine 2 rises with respect to the base portion 9. An example is shown in which the entire intermediate portion 10 is formed in a substantially T-shape and extends perpendicularly to the flat plate portion 10d. In this embodiment, two end portions 10b of the intermediate portion 10 are formed, and the first and second linear body holding portions 13 and 14 are provided in each of them, just as in the embodiment shown in FIGS. The cables 5 and 6 are sequentially provided, and the cables 5 and 6 are held on these, respectively. Of course, also in the embodiment shown in FIG. 5, for each of the second linear body holding portions 14, the third, fourth ...
It is also possible to sequentially connect the linear body holding portions as shown in FIG. Other configurations in FIG. 5 are the same as those shown in FIGS. 2 and 3.

In each of the above-described embodiments, the other end of the arcuate portion of the linear body holding portion farthest from the intermediate portion 10, that is, the tip end portion thereof, is curved so as to escape from the opening portion of the holding portion. When the portion 16 is integrally formed, when the cable is inserted into the opening, the cable can be smoothly inserted into the arcuate portion while being guided by the guide portion 16. Moreover, when removing the cable from the arcuate portion, put your finger on the guide portion 16 and push the guide portion 16 away from the opening (the direction indicated by arrow B in FIG. 3) to open the opening greatly. The cable can be easily removed from the arcuate portion.

By the way, the first and second cables 5 and 6 shown in FIGS. 2 and 3 are inserted in the respective arcuate portions 11 and 12 in order to prevent them from coming off the clamp 8, that is, arrows A ₁ and It is usually arranged to be biased in the direction of A ₂ . For example, the second cable 6 and the clamp 8
When not held by, the cable 6 is arranged so as to extend in the state shown by the chain line in FIG.
When it is held by the clamp 8, it extends to the state shown by the solid line. By doing so, the cable 6 is fitted in the second linear body holding portion 14 of the clamp 8 while being biased in the direction shown by the arrow A ₂ in FIG. Similarly, the first cable 5 is also arranged so as to be biased in the direction of arrow A ₁ .

Therefore, the clamps 8 are provided with the cables 5, 6
Will receive an external force in the directions of arrows A ₁ and A ₂ . At that time, the conventional clamp only holds one cable, so by the external force received from that cable,
The clamp may be easily bent and deformed, and the cable holding function may be deteriorated. Therefore, in the past, the plate thickness of the clamp was set to be large to increase its rigidity and prevent it from being largely deformed by the external force received from the cable, but this increases the cost of the clamp, and It suffered from the drawback of increasing its weight.

On the other hand, in the clamp 8 shown in FIGS. 2 and 3, the first and second linear body holding portions 1 are provided.
3 and 14 are fixed to the head cover 2a of the engine 2 via the intermediate portion 10 and the base portion 9, and both openings 13a and 14a thereof face in opposite directions to each other, so that these holding portions 13 are held. Even if each of the cables 5 and 6 held in the clamps 14 and 14 exerts an external force on the clamp 8 in the directions of the arrows A ₁ and A _{2, the} directions of the external forces are opposite to each other, and the external forces cancel each other out and balance each other. . For this reason,
Even if the plate thickness of the clamp 8 is set thinner than the conventional one, it is possible to prevent the clamp 8 from being bent and deformed by an external force received from the cables 5 and 6. This is exactly the same in the embodiments shown in FIGS. 4 and 5. In order to obtain such an effect more reliably, it is desirable to provide an even number of linear body holding portions in which the openings of the linear body holding portions adjacent to each other face in opposite directions.

Further, as shown in FIG. 3, when the openings 13a, 14a of the linear body holding portions 13, 14 adjacent to each other are directed in opposite directions, the respective linear body holding portions 13, 14 are formed.
It is possible to more reliably prevent the first and second cables 5 and 6 held by 14 from coming off, and to enhance the holding function thereof. That is, since the first cable 5 held by the first linear body holding portion 13 is located inside the arcuate portion 11, the first cable 5 is elastically deformed with respect to the arcuate portion 11 in the direction in which the diameter thereof is reduced. It acts to prevent deformation. This means that the opening portion 14a of the second linear body holding portion 14 becomes difficult to open and expand, which makes it difficult for the second cable 6 to separate from the arcuate portion 12. Similarly, the second cable 6 held by the second linear body holding portion 14 functions to prevent the arcuate portion 12 from being deformed in the direction of reducing the diameter, whereby the first linear body is held. Opening 1 of holding part 13
3a becomes difficult to open and spread, and prevents the first cable 5 from coming off from the arc-shaped portion 11 thereof. Such an action can be similarly obtained in the embodiments shown in FIGS. 4 and 5.

By the way, in each of the above-mentioned embodiments, the flat plate portion of the intermediate portion 10 connected to the base portion 9 of the clamp 8, that is, the entire intermediate portion 10 in the examples of FIGS. 3 and 4, is shown in FIG. In the above example, the flat plate portion 10d excluding the tip side portion 10c is provided substantially upright in the vertical direction with respect to the base portion 9. Moreover, the same number of linear body holding portions are arranged in each of the spaces S ₁ and S ₂ partitioned by the plane P including the flat plate portion. Therefore, the total weight of the clamp 8 and the cables 5 and 6 held by the clamp 8 is balanced on the left and right with the plane P as the center, and the clamp 8 is less likely to be deformed. Therefore, even if the plate thickness of the clamp 8 is set thin, it can be prevented from being permanently deformed,
The weight and cost of the clamp 8 can be reduced.

In the clamp 8 shown in FIGS. 2 to 4, a bead 17 is formed in the intermediate portion 10 thereof, and the rigidity of the intermediate portion 10 is enhanced by this, and the bead 17 is as shown in FIG. And extends to the inside of the arcuate portion 11 of the first linear body holding portion 13, and the arcuate portion 11
When the bead 18 extending from the inside to the inside of the arcuate portion 12 of the second linear body holding portion 14 is formed, both arcuate portions 11, 1 are formed.
The rigidity of 2 can be increased, and since the first and second cables 5 and 6 held by these hit the ends of the beads 17 and 18, it is much more effective that they are separated from each arcuate portion. Can be blocked. This structure can also be applied to the clamp shown in FIGS. 4 and 5. The other configuration in FIG. 6 is the same as that in FIG.

The present invention can be applied not only to cables but also to clamps for holding various linear members such as wires, harnesses and hoses.

[0023]

According to the structure of the first aspect, it is possible to hold a plurality of linear bodies together in one linear body holding clamp, thereby reducing the cost of the entire clamp. Moreover, since the openings of the first and second linear body holding portions are opened in directions opposite to each other, it is possible to balance the external force applied to the clamp by the linear bodies held by these and to hold the clamp. Even if the plate thickness is set to be thin, it is possible to prevent the problem that it is deformed.

According to the clamp of the second aspect, the total weight of the clamp and the linear body held by the clamp can be balanced, and the clamp deforms even if the plate thickness of the clamp is set thin. You can prevent malfunctions.
