In an electric power steering system, a second bevel gear is allowed to move
toward
a first bevel gear and is biased by a biasing member toward the first bevel gear
thereby to be moved toward the first bevel gear as following the wearing away of
these bevel gears.
In an electric power steering system, a support shaft formed with the first bevel
gear at its distal end is rotatably supported by a retaining member, which is mounted
to a support-shaft housing as allowed to move axially of the support shaft. The
retaining member is adjusted for its position relative to the support-shaft housing
with respect to the axial direction of the support shaft by means of a retaining
member adjuster. The first bevel gear is moved toward the second bevel gear as
following the wearing away of these bevel gears.
In an electric power steering system, the support shaft formed with the first
bevel gear at its distal end is allowed to move toward the second bevel gear and
is biased by the biasing member toward the second bevel gear, so that the first
bevel gear is moved toward the second bevel gear according to the wearing away
of these bevel gears.
