Thus, when a cushioning member (8) is interposed between a ball joint (40) and a rack bar storage part (13) of a housing 1 at a stroke end of the rack bar (3), the cushioning member (8) can be guided to the second inclined surface (832) side.

This electric power steering device is configured so that a ball bearing (7) is retained by a retaining member (8) the axial-direction movement of which is restricted by a second housing (12). More specifically, because the retaining member (8) is not screwed into a housing, there is no risk of the occurrence of galling or loosening due to thermal expansion. Further, if thermal expansion occurs in the retaining member (8), such thermal expansion is absorbed by a first elastic member (91) or a second elastic member (92), and thus there is no risk of a reduction, due to the thermal expansion, in the retaining properties of the retaining member (8) with respect to the ball bearing (7).

ELECTROMAGNETIC ACTUATOR DEVICE AND SUSPENSION DEVICE PROVIDED WITH SAME
An electromagnetic actuator device reduces pulsation and improves thrust, and includes: a magnet; and an armature that moves relative to the magnet. The armature includes: a plurality of teeth formed in a relative movement direction; a plurality of slots between the plurality of teeth; a yoke connecting the plurality of teeth; and a winding around the plurality of slots. The magnet includes a plurality of magnet portions facing the plurality of teeth via a gap and are disposed in the relative movement direction. A relationship between a minimum sectional area Sc1 of one tooth end portion of the armature and a minimum sectional area Sc2 of the other tooth end portion is Sc1>Sc2; and a relationship between the minimum sectional area Sc2 of the other tooth end portion and a sectional area Sy of the yoke in a direction crossing the relative movement direction is Sc2≥Sy.
