Abstract: Due to the meshing of the gears, the following force works on the rack. A separating force (Fα) determined by a pressure angle of gears, a lateral force (Fβ) determined by an angle of torsion of the rack, and drag (Fr) for offsetting angular moment occurring in the rack due to the lateral force (Fβ). A resultant (F) of the force works from the rack on the rack guide. When the line of this resultant (F) is held on the “inner side” of the end portions of the needle bearing 25 in this rolling type rack guide 21, the rotation of the roller 22 becomes stable.

Abstract: A lightweight and low cost gear housing for a steering gear unit is achieved. Together with forming an outward-facing flange shaped convex engagement section 43 around the middle section in the axial direction of a rack shaft 40, a gear housing is constructed that comprises a pinion-side housing 10, a non-pinion-side housing 20, and an intermediate cylindrical section 30. As a result, movement of the rack shaft 40 toward the pinion side and the non-pinion side is restricted by both ends of the pinion-side housing 10. Therefore, portions that require large strength can be limited to the pinion-side housing 10 that is short in the width direction of the vehicle, so by reducing the wall thickness of the intermediate cylindrical section 30, or by making the intermediate cylindrical section 30 using a flexible material, it is possible to make the member lightweight, as well as processing become easier, so it becomes possible to reduce the manufacturing cost.

Abstract: An electric power steering device having a speed reduction gear using a toothed belt and capable of preventing the speed reduction gear from being locked and steering from being disabled even if the toothed belt is broken. A clearance Δ between the inner surface (21x) of the second housing (21b) of the speed reduction gear (40) and the rear surface (29a) of the toothed belt (29) applied to a toothed pulley (27) is formed larger than the tooth depth (H) of the toothed belt (29) (Δ>II). Thus, even if the toothed belt (29) is broken, the toothed belt (29) is not caught between the inner surface (21x) of the second housing (21b) and the outer peripheral surface (27a) of the second toothed pulley (27), and the toothed pulley (29) is not locked.
