PURPOSE: To easily provide a specified inertial moment and
natural frequency by using a same material tubular body, to
increase freedom of adjustment of strength of a steering wheel
and to simplify production control and part control of the
tubular body. CONSTITUTION: A steering wheel is formed by
bending a metal tubular body 17 circular and welding both end
parts. One piece or more than one piece of line bodies 21 having
elasticity are inserted into a part or the whole of the inside
of tubular body 17 along the tubular body 17. Additionally, it
is possible to form the line body 21 to be inserted into the
inside of the tubular body 17 spiral to increase a shortage of
reaction force due to elasticity. Next Patent: HOLE COVER
