Title:
STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/058015
Kind Code:
A1
Abstract:
In a steering device according to the present invention, a recess (33) has a first inclined surface (831) and a second inclined surface (832) that are asymmetric in the axial direction of a rack bar (3), and the second inclined surface (832) has a gentler slope than the first inclined surface (831). 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. Resultantly, it is possible to inhibit a change in cushioning properties caused by interposing, between the rack bar (3) and a rack bar insertion hole (130) of the housing (1), a portion of a thick section (81) of the cushioning member (8) that has bulged and deformed in the radial direction in conjunction with compressive deformation in the axial direction, and it is possible to ensure stable cushioning properties of the cushioning member (8).
