Patent ID: 7201075

Claim:
An electric power steering apparatus for transmitting rotating force of a steering assisting motor to a worm shaft having a worm and being rotatably supported in a gear housing through a bearing and to a steering shaft provided with a worm wheel meshing with said worm and for assisting steering, said apparatus comprising: a fitting hole portion of said gear housing for fitting with and holding said bearing, the portion being formed of first and second split members formed by splitting said portion into two along a longitudinal direction of said fitting hole, the first and second split members being separated by a gap, the first split member being movable toward said worm wheel with respect to the second split member and a position of the second split member being fixed; a member for displacing said first split member toward the second split member in order to reduce the size of the gap and adjust the meshing state of said worm shaft supported by said bearing; and an elastic member provided between the second split member and said bearing, the elastic member being in contact with said second split member and said bearing, wherein said displacement member has a member for connecting said pair of split members, and an energizing member disposed between said connecting member and said first split member and having elastic recovery force greater than an elastic recovery force of said elastic member.
