ELECTRIC POWER STEERING APPARATUS
First Claim
1. An electric power steering apparatus comprising:
- a steering column that rotatably supports a steering shaft and that is swung around a tilting spindle during tilt adjustment;
an electric motor that is supported by the steering column and that is used as a steering auxiliary; and
a fixing bracket that supports the steering column through the tilting spindle;
wherein the fixing bracket includes a pair of side plates facing each other with the steering shaft therebetween in a vehicle width direction and a connection member through which the pair of side plates are connected together,either one of the pair of side plates is provided with a first restraining portion that restrains the steering column from rotating in a first rotation direction around the tilting spindle,a remaining one of the pair of side plates is provided with a second restraining portion that restrains the steering column from rotating in a second rotation direction opposite to the first rotation direction,the first restraining portion is a hook engagement portion that is capable of being hooked on from below and capable of being engaged with a first projection extending from the steering column,the second restraining portion is a contact portion that is capable of coming into contact from above with a second projection extending from the steering column,an inner surface of the side plate having the hook engagement portion is disposed near a side part of the electric motor, andwith respect to the vehicle width direction, a distance between the side plate having the hook engagement portion and a central axis of the steering shaft is longer than a distance between the side plate having the contact portion and the central axis of the steering shaft.

Abstract
An electric power steering apparatus includes a steering column that is swung around a tilting spindle during tilt adjustment, a fixing bracket that supports the steering column through the tilting spindle, and an electric motor that is supported by the steering column and used as a steering auxiliary. The fixing bracket includes a pair of side plates facing each other with the steering shaft therebetween in a vehicle width direction and a connection member through which the pair of side plates are connected together. Either one of the pair of side plates is provided with a first restraining portion that restrains the steering column from rotating in a first rotation direction around the tilting spindle. The remaining one of the pair of side plates is provided with a second restraining portion that restrains the steering column from rotating in a second rotation direction opposite to the first rotation direction.
