Title:
STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/047786
Kind Code:
A1
Abstract:
A steering device (20) comprises: an actuator including a motor (23) configured to generate torque corresponding to steering of a steering wheel (26) of a vehicle (10), and a speed reducer (25) configured to decrease the speed of rotation of the motor (23); and a ball screw mechanism (48) configured to convert rotation imparted via the speed reducer (25) into rotation of an output shaft (44) linked to a steered wheel (13). The speed reducer (25) and the ball screw mechanism (48) are configured such that load torque increase/decrease characteristics with respect to a steering direction that arise when the steering wheel (26) is steered are mutually opposite in the speed reducer (25) and the ball screw mechanism (48).
