Claims

[Scope of utility model registration request]

a pinion rotated by a steering wheel;
A rack comprising: a rack bar having a series of helicoids that mesh with the pinion and driven in its axial direction by the pinion; and tie fours lowers connected to both ends of the rack bar by ball joints. In the and pinion type steering device, the pinion is connected to the rack bar.
When the pinion drives the rack bar in its axial direction, the tie rod transfers the rotational moment about the axis of the rack bar to the rack bar via the ball joint.
A rack characterized in that the center of the ball joint is offset from the axis of the rack bar so as to be balanced by the rotational moment about the axis acting on the rack.
and biniosi type steering device.・
