摘要： When the guide bracket 61 is fixed to the vehicle-mounting bracket 21 by the guide pin 71, the upper surfaces 24c, 24c of the capsules 24, 24 are in contact with the lower surfaces 61c, 61c of the flange portions 61b, 61b on the guide bracket 61, and the first engaging portions 64, 64 and the second engaging portions 65, 65 engage with the capsules 24, 24. As a result, even before fixing the vehicle-mounting bracket 21 and the guide bracket 61 to the vehicle body 41 by the bolt 22, the guide bracket 61 does not rotate with respect to the vehicle-mounting bracket 21 about the guide pin 71, or move in the forward and rearward direction, or in the vehicle body width direction.

摘要： In the event that a moment in a bending direction is generated in a pinion shaft, for example, when a vehicle is involved in a collision or the like, since a bending facilitating portion which is a circumferential groove 111e bends, stress is concentrated hereon, and no large bending stress is generated in any case between a rolling bearing 102 and a support member 104. Consequently, an excessively large bending force is transmitted in no case to a four point contact type ball bearing 103.

摘要： A ball bearing 34 serving as a support reference for a pinion shaft 2 is located directly under a worm wheel 51. Thus, even when a temperature change occurs around the electric power steering apparatus, the engagement position between the worm wheel 51 and the worm 53 shifts only slightly in the axial direction of the pinion shaft 2. Furthermore, a bearing hole 47 into which an outer race of a lower needle bearing 36 is pressed and a bearing hole 45 into which an outer race of an upper ball bearing 34 is pressed are formed in a common lower gear box 41, and can be fabricated by through processing using a boring tool from the bearing hole 45 side.
