Title:
ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/058016
Kind Code:
A1
Abstract:
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).
