Abstract: A housing for an electric power steering device that has an electric motor, a speed reduction mechanism, a ball screw mechanism, and a rack bar. The housing has a first housing having a first end portion covering a part of the rack bar and a second end portion with a portion accommodating at least a part of the speed reduction mechanism. The first housing includes a rack bar insertion hole portion; an electric motor shaft insertion hole portion having a cylindrical shape on a radially outer side of the rack bar insertion hole portion, through which an electric motor shaft is inserted; and a fastening portion having an annular shape overlapping with an inner peripheral surface of the electric motor shaft insertion hole portion along the longitudinal direction of the rack bar when an axis extending in the rack bar longitudinal direction is viewed from a radially outer side.

Abstract: Provided is a steering device including a lock nut that fixes an outer race of a turning nut threadably engaged with a rack bar. A loosening prevention protruding portion formed on a lock nut main body is brought into contact with a radial-direction abutting portion to prevent loosening of the lock nut with a frictional force. At the same time, a lock nut recessed portion for reducing mechanical stiffness is formed in an outer peripheral surface of the loosening prevention protruding portion so that an external force acting from the outer race is buffered by the lock nut recessed portion. In this manner, a decrease in contact area between the loosening prevention protruding portion and the radial-direction abutting portion is reduced.
