Abstract:
An electric power steering system comprising:a support shaft integrally rotatably connected with an output shaft of an electric motor; a first bevel gear, including a first axis, provided at a distal end of the support shaft; a second bevel gear, including a second axis, meshed with the first bevel gear with the axes intersecting each other; a rack shaft linearly moved thereby steering steerable road wheels; a rotary element rotatably supported by the rack housing as enclosing the rack shaft and operating to transmit the rotation of the electric motor via the first bevel gear and the second bevel gear; and a power conversion mechanism formed between the rotary element and the rack shaft for converting the rotary motion of the rotary element to the linear motion of the rack shaft; wherein the support shaft is allowed to move toward the second bevel gear and is biased toward the second bevel gear by a biasing member.
