Embodiment Construction
[0117] [the first example of embodiment]
[0118] pass Figure 1-14 A first example of an embodiment of the present invention will be described.
[0119] The electric power steering device of this example is the same as the above-mentioned Figure 23-24 In the conventional structure shown, the steering wheel 1 is attached to the rear end of the steering shaft 2 , the front end of the steering shaft 2 is rotatably supported in the housing 3 , and the worm wheel 4 is fixed to the part driven by the steering shaft 2 . A worm tooth 5 meshing with the worm wheel 4 is provided at an axially intermediate portion of the worm shaft 6a. Both ends in the axial direction of the worm 8 rotationally driven by the electric motor 7 are rotatably supported in the housing 3 by a pair of rolling bearings (ball bearings in the illustrated example) 9a, 9b. Further, the worm gear 5 provided on the worm shaft 6a is pressed against the worm wheel 4 by providing the preload imparting mechanism 15 be...
