one end portions of the plurality of cables are connected to the first module in the bundled form and the other end portions of the plurality of cables are connected to the respective second modules separately,

wherein the branching module further comprises an elastic member, and the branching module is fixed to at least one of the plurality of cables by an elastic force of the elastic member, wherein:

the branching module further comprises:

a fixed cover;

a movable cover; and

a rotation point which is disposed between the first cable insertion portion and the second cable insertion portion and connect the movable cover to the fixed cover rotatably;

the elastic member is disposed between the movable cover and the fixed cover; and

the movable cover is fixed to the at least one of the plurality of cables by the elastic force of the elastic member.

2. The wiring member according to claim 1 , wherein:

the elastic member is disposed between the rotation point and the second cable insertion portion; and

the movable cover is configured to be fixed to the at least one of the plurality of cables when the elastic member expands, and is configured to be movable relative to the plurality of cables when the elastic member is contracted.

3. The wiring member according to claim 2 , wherein:

the first cable insertion portion has a first cable organizer having plural first insertion passages in which the plurality of respective cables are inserted; and

the second cable insertion portion has a second cable organizer having plural second insertion passages in which the plurality of respective cables are inserted.

4. The wiring member according to claim 3 , wherein:

the plurality of cables are inserted in the first cable insertion portion in such a manner as to be bundled together in two stages.

5. The wiring member according to claim 4 , wherein:

the first cable organizer has a step portion that is continuous with at least one of the plurality of first insertion passages; and

the at least one of the plurality of cables is fixed to the movable cover so as to be sandwiched between the movable cover and the step portion.

6. The wiring member according to claim 4 , wherein:

the plural first insertion passages are arranged in two stages;

the plural second insertion passages are arranged in one stage;

the plurality of second insertion passages are in contact with the fixed cover; and

the elastic member is disposed between the movable cover and the second cable organizer.

7. The wiring member according to claim 4 , wherein:

the first cable organizer has a step portion that is continuous with at least one of the plurality of first insertion passages;

the at least one of the plurality of cables is fixed to the movable cover so as to be sandwiched between the movable cover and the step portion;

the plural first insertion passages are arranged in two stages;

the plural second insertion passages are arranged in one stage;

the plurality of second insertion passages are in contact with the fixed cover; and

the elastic member is disposed between the movable cover and the second cable organizer.

8. A wiring member comprising:

a first module having a first communication unit which is electrically connected to a first host apparatus;

plural second modules having respective second communication units which are electrically connected to a second host apparatus;

a cable module having plural cables which connect the first communication unit to the second communication units; and

a branching module which is disposed at a prescribed position in the cable module, which has a first cable insertion portion in which the plurality of cables are inserted in a bundled form and a second cable insertion portion in which the plurality of cables are inserted separately, and which is configured to be fixed to at least one of the plurality of cables in a first state and is configured to be movable relative to the plurality of cables in a second state, wherein:

one end portions of the plurality of cables are connected to the first module in the bundled form and the other end portions of the plurality of cables are connected to the respective second modules separately,

wherein:

the branching module further comprises:

a fixed cover;

a movable cover; and

an elastic member disposed between the movable cover and the fixed cover;

the movable cover is fixed to the at least one of the plurality of cables by an elastic force of the elastic member in a state that the plurality of cables are inserted in the respective first insertion passages; and

the fixed cover, the movable cover and the elastic member are configured to be movable simultaneously relative to the plurality of cables in the second state.

9. The wiring member according to claim 8 , wherein:

the first cable insertion portion has a first cable organizer having plural first insertion passages in which the plurality of respective cables are inserted; and

the second cable insertion portion has a second cable organizer having plural second insertion passages in which the plurality of respective cables are inserted.
