【Example】

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. First, Figure 5 1 is a steering wheel equipped with a telescopic mechanism (not shown). This is a switch base installed in the steering column section, and as is well known, this switch base is equipped with a turn switch. There are many switches such as signal switches and light switches. A harness 2 that bundles the wires of each switch is derived from the switch base 1. It is. The switch base 1 controls the position of the steering wheel (not shown). Moves with the steering wheel when adjusting the steering shaft in the axial direction It looks like this.

[0008] A connector 3 is provided at the tip of the harness 2, and this connector 3 is connected to a predetermined portion. Fixed position.

[0009] A case 4 provided to house the intermediate portion of the harness 2 is shown in FIGS. 1 to 3. As shown, it is constructed by combining two paired side plates 4a and 4b, and A harness 2 is inserted through openings 5 and 6 formed at the bottom and at the bottom.

0010 Two holders 7 provided in the case 4 are arranged facing each other with a predetermined interval. supporting plates 8a, 8b, and passing through the center of both supporting plates 8a, 8b. 8a, 8b rotatably supported on the case 4 and between the support plates 8a, 8b. Two rollers 11 are rotatably attached to both sides via pins 10, respectively. a, 11b, and a band attached to each pin 10 to hold the harness 2 12, and the harness 2 is connected to both rows in the case 4 as shown in FIG. It is held in an S-shaped bent state by extending it over the rails 11a and 11b. Ru.

[0011] Therefore, in the above configuration, when adjusting the position of the steering wheel, the switch When switch base 1 moves in the direction of arrow A in Figure 5, the switch base of harness 2 The station 1 side also moves in the same direction. Then, as shown in FIG. The harness 2 rotates in the direction of arrow B around the support shaft 9, and the harness 2 is moved inside the case 4. It comes to be stored and held in a greatly bent state.

0012 In addition, in the state shown in Figure 1, when adjusting the position of the steering wheel, the switch When base 1 moves in the opposite direction of arrow A, switch base 1 side of harness 2 also move in the same direction. In this case, as shown in FIG. The case 7 rotates about the support shaft 9 in the opposite direction of arrow B, and the harness 2 rotates around the case 4. It is stored and held in an extended bent state compared to the case shown in FIG.

[0013] In this way, as the holder 7 rotates, the bent state of the harness 2 inside the case 4 changes. By changing, expansion and contraction of the harness 2 is allowed.

[0014] According to the embodiment described above, the harnesses 2 do not cross within the case 4. Therefore, compared to the conventional structure in which the harness is stored in a loop, the harness 2 The case 4 that houses the case 4 can be made thinner, and the harness 2 can be Since there is no overlap in the thickness direction of harness 2, the required length of harness 2 is shorter than that of conventional harnesses. You can shorten the length.

[0015] 6 to 8 show a second embodiment of the present invention, which is different from the first embodiment described above. Let's explain the parts.

[0016] That is, the connector holding portion 14 is integrated with the connector 3 side of the case 13. is formed. The holders 15 provided in the case 13 have a predetermined interval. Two support plates 16 (only one is shown) are arranged facing each other, and the space between these two support plates 16 is Two pieces rotatably attached via pins 17a and 17b on both sides of the rollers 18a, 18b and harness 2 attached to each pin 17a, 17b. and a band 19 for holding one of the rollers 18a. A pin 17a is rotatably and slidably supported in a long hole 20 formed in the case 13. In this case as well, the harness 2 is connected to both sides inside the case 13 as shown in FIG. It is held in an S-shaped bent state by extending it over the rollers 18a and 18b. There is.

[0017] As the switch base 1 moves, the switch base 1 side of the harness 2 moves with the arrow. When the holder 1 is moved in the direction of mark A, the holder 1 is moved in the case 13 as shown in FIG. 5 rotates in the direction of arrow B around one pin 17a, and along with this, the harness 2 It is stored and held in a largely bent state within the base 13.

[0018] In addition, in the state shown in Figure 6, when adjusting the position of the steering wheel, the switch Base 1 moves in the opposite direction of arrow A, and as a result, harness 2 moves to the switch base 1 side. If it moves in the direction of the opposite arrow A, the inside of the case 13 will move as shown in FIGS. 7 and 8. , the holder 15 rotates in the opposite direction of arrow B around the pin 17a, and as a result, the holder 15 rotates in the opposite direction of arrow B -nes 2 is stored and maintained in the case 13 in an extended and bent state compared to the case shown in Fig. 6. It comes to be held. At this time, one pin 17a also moves along the elongated hole 20. Ru.

[0019] In this way, as the holder 15 rotates, the harness 2 inside the case 13 is By changing the bending state, the harness 2 is allowed to expand and contract. The second embodiment also has the same effects as the first embodiment.

[0020]

[Effect of the idea]

As is clear from the above description, according to the present invention, the harness is placed inside the case in an S-shape. Because it is designed to be stored and held in a bent state, the harness cannot be stored inside the case. The two do not intersect and do not overlap in the thickness direction of the case. -The case that stores the harness can be made thinner than before, and the required length of the harness can be reduced. This has the excellent effect of making it shorter.
