Title:
STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/047712
Kind Code:
A1
Abstract:
This steering device (20) comprises: a shaft (24B2) which rotates in an interlocked manner with steering of a steering wheel (26); a ball screw mechanism (48) which converts rotation of the shaft into rotation of an output shaft (44); and a speed reducer (25) which applies a torque to the shaft. The ball screw mechanism has a first housing (40), a ball screw shaft (41) which is connected to the shaft in an intermeshed manner, and first and second bearings (46, 47) which support the ball screw shaft. The speed reducer has a second housing (50) and a third bearing (53) which supports the shaft. An outer diameter (φ1) of the shaft is set such that a third centerline (O3) passing through the cross-sectional center of the third bearing is positioned radially outside a first centerline (O1) passing through the cross-sectional center of the first bearing or a second centerline (O2) passing through the cross-sectional center of the second bearing.
