Claims

[Claims for Utility Model Registration] 1. In order to relay-connect an electric signal line wired to the steering column and an electric signal wire wired to a handle rotatable with respect to the column, the above-mentioned handle A spiral coil 3, which is flexible and spirally formed to follow the rotation of the steering column and has a plurality of electrical conductors 5 along the spiral direction, is attached between the steering column and the handle. In the electrical signal relay connection structure equipped between the coils 3 and 3, the coil 3 is housed in a storage case, and the storage case consists of a lower case 2 fixed to the steering column side and a lower case that rotates together with the steering wheel. It consists of an upper case 1 rotatably attached to a case 2, and at least one of the upper and lower cases 1 and 2 includes a connector enclosing wall 1a protruding from the outer surface of the case at a predetermined position, On the other hand, at least one of the inner and outer ends of the coil 3 is fixed and connected to printed wiring boards 4a and 4b, and the wiring board is connected to one of the cases 1 and 2a.
, 2. An electrical connection structure between a steering wheel and a steering column, characterized in that the steering column and the steering column are fixed in the corresponding cases 1 and 2 so as to protrude from the inside of the connector walls 1a and 2a. 2. The electrical connection structure between a steering wheel and a steering column according to item 1, wherein a lubricant is applied to the inner and outer surfaces of the spiral coil 3.
