Steering device
First Claim
1. A steering device comprising:
- an actuator provided at an intermediate portion of a steering shaft extending downward from a steering handle to pass through a dashboard of a vehicle body for altering the transmission ratio in rotation between upper and lower portions of the steering shaft in dependence on a traveling state;
a cable case of a double cylindrical structure arranged on an upper surface of the actuator;
a case inner cylindrical component constituting the inside of the cable case and fixed to the actuator;
a case outer cylinder component constituting the outside of the cable case and rotatable relative to the case inner cylindrical component;
a spiral cable provided for supplying the actuator with electric power and housed inside the cable case with itself being wound, the spiral cable being fixed to the case inner cylindrical component at one end thereof and to the case outer cylindrical component at the other end thereof; and
a cylindrical rubber boot covering the circumferential surface of the actuator;
wherein;
an upper side portion of the rubber boot is fitted on the case outer cylindrical component to be fixed thereto;
a mid-portion of the rubber boot is fixed to the dashboard; and
a lower end of the rubber boot seals against the lower portion of the steering shaft.

Abstract
In a steering device 10, the upper side portion of a rubber boot 120 is fixedly fitted on a case outer cylindrical component 41 of a cable case 39, and the lower side portion of the rubber boot 120 is fixed to a dashboard 100 of a vehicle body 14 over the entire circumference thereof. Thus, the case outer cylindrical component 41 can be secured against rotation more firmly compared with a prior art steering device wherein such a case outer cylindrical component is fixed at two portions thereon by means of a wire of a V-letter shape. Further, the problem attendant on the wire of the V-letter shape in the prior art steering device no longer arises even in the car models wherein the case outer cylindrical component 41 and the dashboard 100 are relatively far from each other. That is, it can be realized to secure the case outer cylindrical component 41 of the cable case 39 against rotation relative to the vehicle body 14 even in any car model.
