ABSTRACT:
A vehicle steering system includes a sound absorbing material made of sponge and attached to an elastic joint which connects a second steering shaft extending from a steering wheel and a third steering shaft extending from a steering gear box to each other. The sound absorbing material faces an opening in a joint cover which is mounted on a dashboard and through which the second steering shaft passes. Therefore, the sound absorbing material absorbs noise which is produced in the steering gear box such that the noise does not pass from the engine room side through the opening in the joint cover to the vehicle compartment side, thereby preventing transmission of the noise to the vehicle compartment side. Further, the sound absorbing material requires only a simple shape and construction, thereby reducing the cost. Furthermore, the sound absorbing material does not come into sliding contact with the second steering shaft, and thus does not produce sliding noise or sliding resistance.
