Abstract

A shaft coupling mechanism (1) for an electric power steering device comprises a coupling base (3) coupled to a rotating shaft (2), a coupling base (5) coupled to a rotating shaft (4), a rotation transmission member (8) arranged between the rotating shaft (2) and the rotating shaft (4) via the coupling bases (3, 5) and composed of a pair of rigid rotation transmission members (6, 7) for transmitting rotation in an R direction centered about the axial center (O) of the rotating shaft (2) to the rotating shaft (4), an elastic member (9) arranged between the rotation transmission members (6, 7), superimposed over the rotation transmission members (6, 7) in the axial direction, and linked to the rotation transmission members (6, 7), and a linking means (10) for linking the pair of rotation transmission members (6, 7) together.

Description

technical field [0001] The present invention relates to a shaft coupling mechanism suitable for coupling a rotation shaft on a rotation source side such as an electric motor in an electric steering apparatus with a rotation shaft on an operation side such as a steering shaft of an automobile. Background technique [0002] The electric steering apparatus serves to facilitate manual steering of a steering wheel by adding torque based on rotation of an output rotary shaft of an electric motor to torque based on rotation of a manually operated steering wheel. In such an electric power steering apparatus, the steering shaft on the steering wheel side and the rotation shaft on the output rotation shaft side of the electric motor are coupled by means of a shaft coupling mechanism (coupling). [0003] In the case where the steering shaft and the rotation shaft are coupled by means of a shaft coupling mechanism, the shock when the output rotation shaft of the electric motor is revers...
