However, in such a conventional one, since the harness 1 is routed along the curved dashboard upper 2, it is routed linearly. Compared to the case, it is necessary to lengthen the harness 1 and the distance from the wiring position to the electric device is long, so that the branch line of the harness 1 must be lengthened.

Further, since the dashboard upper 2 has a curved shape, and if this shape is different depending on the vehicle type, the length of the curved line changes greatly, so that the harness 1 routed along the dashboard upper 2 It was not possible to make the length constant and share it.

On the other hand, when the harness 1 is routed, it must be carried out in a narrow space in the vehicle compartment, so that the workability is poor and the productivity is lowered.

Therefore, the present invention, regardless of the vehicle type,
It is an object of the present invention to provide a harness routing structure that allows harnesses of the same length to be used and allows the harnesses to be easily routed.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a steering member which is arranged along the vehicle width direction and which supports a steering column. A harness is arranged along the steering member. Claim 2

Further, a long cylindrical protector for accommodating the harness so that the harness can be inserted and removed is provided, a locking portion is provided on the protector, and a locked portion for locking the locking portion is provided on the steering member. Good.

[0011]

According to this structure, since the harness is routed along the substantially straight steering member, the total length of the harness is shortened as compared with the case where the harness is routed along the curved dashboard upper. In addition, since the distance from the steering member to the electric device or the like is usually shorter than the distance from the dashboard upper, the branch line of the harness can be shortened.

Even when the vehicle width changes depending on the vehicle type, the amount of change is small compared to the change of the curved dashboard upper, so a harness with a certain length is prepared in advance, and this harness is used for a plurality of vehicle types. Can be shared.

Furthermore, after the harness is routed to the steering member, the steering member is attached to the vehicle body to improve workability as compared with the conventional case where the harness is routed in the narrow space of the vehicle compartment. In addition to being able to improve remarkably, since the steering member is usually arranged in front of the dashboard upper, the workability in exchanging the harness can be improved.

On the other hand, by disposing at least one end portion of the steering member via the bracket, the size of the bracket or the mounting position between the steering member and the bracket is changed to change the vehicle width. Since it is possible to deal with this, it is possible to make the length of the steering member constant so that the steering member can be commonly used for a plurality of vehicle types, and also the harness to be routed can be commonly used.

Further, by providing a recess in the longitudinal direction of the steering member and accommodating the harness in this recess, it is possible to avoid interference between the harness and other parts and protect the harness.

Further, a protector for accommodating the harness is provided, and the protector and the steering member are provided with an engaging portion and an engaged portion for engaging with each other, whereby the harness is accommodated in the protector and the protector is engaged. Since the harness can be routed to the steering member only by locking the portion and the locked portion of the steering member, the wiring work can be performed easily and quickly.
