摘要： A reducer of an electric power steering apparatus includes: a worm shaft having a first end thereof supported by a first bearing coupled to a housing and a second end supported by a second bearing coupled to the housing; a damper axially supported on an outer race of the second bearing; and a damper support member having a first side axially supported on the damper and a second side supported on an inner face of the housing. The worm shaft can be assembled with constant rotational torque at an accurate position with respect to the centers of the bearings at the opposite ends. And, the axial and radial movements of the worm shaft can be buffered and the load applied to the worm shaft in the direction in which the worm shaft is engaged with the worm wheel can be reduced.
