Abstract

An electric power steering device is provided with a worm which is connected through a joint to the rotating shaft of an electric motor in a pivotable manner. A first end and a second end of the worm are supported by a first bearing and a second bearing. A pair of elastic members elastically presses the worm to the neutral position in the axial direction. An annular plate spring held by a housing presses the second end to the worm wheel side through the second bearing. A synthetic resin member having a sliding contact surface in contact with the plate spring is integrally provided to the second bearing.
