When assembling the above two cables between the bar handle and the carburetor (or throttle body), it takes more man-hours to pass through the gaps in the body frame, in-vehicle parts, various covers, etc. than with a single cable. Is required.
Therefore, it is conceivable to bundle two cables as they are with a bundling member. However, this increases the number of parts, leading to an increase in cost. Further, the outer shape of one bundled cable is two. In some cases, the cable becomes larger than the case where the outer shapes of the cables are simply matched, and it becomes difficult to assemble in a narrow gap.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a cable structure capable of suppressing an increase in the number of parts and an increase in outer shape.

  In order to solve the above-described problem, the present invention is configured so that the drive unit (74, 203) and the driven unit (92, 202) driven by the drive unit (74, 203) include two inner wires (81 , 82), and when the one inner wire is the first inner wire (81) and the other inner wire is the second inner wire (82), the first inner wire (81) is connected to the drive section ( 74, 203) and pulling it against the urging force applied to the driven part (92, 202) to operate the driven part (92, 202) in one direction, and to move the second inner wire (82). In the cable structure in which the driven parts (92, 202) are operated in the other direction by being pulled in the direction of the urging force by the driving parts (74, 203), the cables (83, 83A, 83B, 31, 131 </ b> A, 131 </ b> B) are a resin-made tubular liner (116) into which the first inner wire (81) is movably inserted, and a first outer tube (114) that houses the liner (116). And the second outer tube (115, 134) in which the second inner wire (82) is movably inserted, and the first outer tube (114) and the second outer tube (115, 134). And a covering member (112, 112A, 132, 135, 136) bundled together.

  According to this configuration, the two outer tubes are bundled with the covering member to form one cable. For example, the cable is passed through a gap or the like existing between the drive unit and the driven unit, and the driven unit and the driven unit are driven. When assembling to the part, the number of man-hours for assembling the cables can be reduced as compared with the case of passing two cables, and the assembling property can be improved. In addition, since the covering of the two outer tubes is shared by one covering member, and the member for bundling the two outer tubes with the covering member for covering is also used, there is no need to provide a special member for bundling. The number of parts can be reduced. Further, since the first inner wire is movably inserted into the liner, the two inner wires do not interfere with each other, so that the slidability and durability of the two inner wires can be ensured. it can. In particular, when the driven portion is driven against the urging force by the driving portion, the first inner wire on which a large tensile force acts is accommodated in the liner so that the first inner wire slides with the resin liner. The durability of the first inner wire can be ensured. Further, since the second inner wire pulled in the direction of the urging force acts only with a small tensile force, it is not necessary to use a liner, so that the outer shape of the entire cable can be further reduced.

7B, a throttle cable 131A, which is a modification of the throttle cable 131 (see FIG. 7A), differs from the throttle cable 131 only in the spring 134 and the covering member 135. That is, the throttle cable 131A is movable within the spring 114, the spring 134 having a smaller outer diameter than the spring 115 (see FIG. 7A), the liner 116, the first inner wire 81, and the spring 134. And a resin covering member 135 that covers and bundles the springs 114 and 134 (the spring 114 constitutes the first outer tube and the spring 134 constitutes the second outer tube).
Thus, by providing no liner in the spring 134 and making the spring 134 have a small diameter, the outer shape of the spring 134 can be made smaller, and the outer shape of the throttle cable 131A can be made smaller. Therefore, the throttle cable 131A can be easily passed through the narrow gap of the vehicle body, and the assembling property can be improved.

7C, a throttle cable 131B, which is a modification of the throttle cable 131 (see FIG. 7A), includes springs 114 and 115, a liner 116, a first inner wire 81, and a second inner wire 82. And a covering member 136 that is integrally formed so that the first tube 112a and the second tube 112b that cover the springs 114 and 115 are connected to each other at an intermediate portion.
Thus, by covering the springs 114 and 115 with the first tubes 112a and 2112b, respectively, interference between the springs 114 and 115 can be prevented, and durability can be further enhanced. Further, the springs 114 and 115 can be reliably held by the first tube 112a and the second tube 112b.

  As shown in FIGS. 2, 4, 5, and 7, the throttle grip 74 and the throttle valve 92 driven by the throttle grip 74 are composed of two first inner wires 81 and a second inner wire. The first inner wire 81 is connected by the wire 82, and the throttle valve 92 is operated in one direction by pulling the first inner wire 81 against the urging force applied to the throttle valve 92 by the throttle grip 74, and the second inner wire 82 is moved to the throttle grip. In the cable structure in which the throttle valve 92 is operated in the other direction by pulling in the direction of the urging force by 74, the cables 83, 83A, 131, 131A, 131B are made of resin in which the first inner wire 81 is movably inserted. A tubular liner 116 and a first outer housing the liner 116 A spring 114 as a tube, springs 115 and 134 as second outer tubes into which a second inner wire 82 is movably inserted, and covering members 112 and 112A that cover and bundle these springs 114 and springs 115 and 134 , 132, 135, 136 so that the two springs 114 and the spring 115 (or the spring 134) are bundled by the covering members 112, 112A, 132, 135, 136 to form one cable. When the cables 83, 83A, 131, 131A, and 131B are passed through a gap or the like existing between the throttle grip 74 and the throttle valve 92 and are assembled to the throttle grip 74 and the throttle valve 92, the two cables are passed respectively. Cable 83 compared to the case 83A, 131,131A, can reduce the number of assembling steps of 131B, thereby improving the assemblability. Further, the covering of the two springs 114 and the spring 115 (or the spring 134) is shared by one covering member 112, 112A, 132, 135, 136, and the covering members 112, 112A, 132, 135, 136 for covering are shared. Thus, since the member for bundling the two springs 114 and the spring 115 (or the spring 134) is also used, it is not necessary to provide a special member for bundling, and the number of parts can be reduced. Further, since the first inner wire 81 is movably inserted into the liner 116, the two first inner wires 81 and the second inner wires 82 do not interfere with each other, so that the two first inner wires 81 are not interfered with each other. The slidability and durability of the wire 81 and the second inner wire 82 can be ensured. In particular, when the throttle valve 92 is driven against the urging force by the throttle grip 74, the first inner wire 81 on which a large tensile force acts is accommodated in the liner 116, so that the first liner 116 made of resin is used. The slidability of the inner wire 81 can be promoted, and the durability of the first inner wire 81 can be ensured. Further, since the second inner wire 82 drawn in the direction of the urging force acts only with a small tensile force, it is not necessary to use a liner, so that the outer shape of the entire throttle cable 83, 83A, 131, 131A, 131B is made smaller. be able to.

In addition, since the spring 134 is formed to have a smaller diameter than the spring 114, the outer shape of the throttle cable 131A can be reduced by making the spring 134 smaller in diameter without providing a liner inside the spring 134, and is narrow. The throttle cable 131A can be easily passed through even in a space, and the flexibility of the throttle cable 131A is improved, so that the assembling property of the throttle cable 131A can be improved.
The covering members 112 and 112A are configured such that the spring 114 and the spring 115 separated from each other are connected by fixing portions 112c and 112e as connecting portions, and the throttle cables 83 and 83A are fixed to the fixing portions 112c and 112e. Since the mounting round hole 112g and the mounting long hole 112h to be used are provided, the screws 113 and the like are inserted into the mounting round hole 112g and the mounting long hole 112h, so that the throttle cables 83 and 83A can be easily mounted on the member. be able to.
