However, although the cable carrier of Patent Document 1 can store a plurality of cables separately, when the number of cables is further increased, the risk of cable entanglement or disconnection is suppressed, and the cables are increased according to the increase in the number of cables. It is necessary to increase the storage capacity of the carrier.

In order to increase the storage capacity of the cable carrier, it is necessary to increase the cable carrier in the width direction and the thickness direction, which increases the space required for arranging the cable carrier.

Moreover, if the radius of curvature of the curved portion of the cable carrier is constant, the gap between the cable guides for allowing the cable carrier to bend increases as the thickness of the cable carrier increases, and the internal cable becomes larger. Expose. In order to prevent excessive bending of the cable carrier and suppress the gap between the cable guides, it is necessary to increase the radius of curvature in the curved portion, which increases the space required in the height direction of the cable carrier.

Further, the belt may be used as a power supply and communication cable.

According to this configuration, the thickness of the holding member can be made smaller because it is not necessary to hold both the power supply cable and the communication cable by the holding member, and the space required in the height direction of the holding member can be increased. It can be made smaller.

Further, the belts may be provided on both sides of the holding member in the thickness direction so that the belt on one side is used as the power feeding cable and the belt on the other side is used as the communication cable.

According to this configuration, the power supply cable and the communication cable can be completely separated by sandwiching the holding member, and noise caused by the power supply cable can be more reliably prevented from riding on the communication cable.

As a result, each holding member can be slightly curved without causing unreasonable deformation, and the radius of curvature of the curved portion provided in the holding member is reduced so as to be able to follow the relative movement of the holding member. The space required in the height direction can be reduced.

Here, the holding member is a carrier cable in which a plurality of cable guides are rotatably connected to each other to store and hold the flexible linear body .

According to this configuration, a carrier cable that is small and difficult to bend like a belt is used as a holding member, but by adopting the above configuration of the present invention, the space required in the height direction of the holding member is relatively small. be able to. In particular, by arranging the carrier cable on the outer side of the curve, which has a larger radius of curvature than the belt or the holding member on the inner side of the curve, it is impossible to make various flexible linear bodies while saving space in the linear body holding structure. Can be held without.

Further, at least a part of the flexible linear body may be a piping tube for accommodating the fluid.

According to this configuration, a flexible linear body that is held by a belt or other holding member by holding the piping tube by either a holding member provided separately from the belt or a holding member provided in a plurality of layers. It is possible to prevent the piping tube from being entangled and deformed, and it is possible to provide a preferred embodiment of the present invention.

Further, at least a part of the flexible linear body may be used as a power feeding cable or a communication cable.

According to this configuration, the power feeding cable and the communication cable are held by either the holding member provided separately from the belt or the holding member provided in a plurality of layers, so that the bending is held by the belt or another holding member. It can be separated from the sex line to prevent the power supply cable and communication cable from being entangled and deformed. In particular, by holding either the power supply cable or the communication cable, the communication cable and the power supply cable that causes noise in the communication cable can be separated, and a preferred embodiment of the present invention is provided. Can be done.

As described above, according to the present invention, a holding member for holding a flexible linear body along its length direction and a belt having a core wire made of a conductive material are arranged side by side in the thickness direction. By doing so, or by providing the holding members in a plurality of layers, the thickness of each holding member is reduced.
