Claims

[Scope of utility model registration request]

A rack housing, a support yoke attached to the rack housing, a helical rack supported on a concave surface of the support yoke, and a helical pinion meshed with the rack, and the support yoke is connected to the rack housing with respect to the axis of the rack. and a first direction in a plane that includes the axis of the rack and is parallel to the axis of the pinion.
a third direction perpendicular to the first direction and the second direction;
the pinion, the rack, and the support yoke are arranged in this order along the third direction, and the concave surface is located closer to the support yoke than the maximum width part of the rack along the second direction, In a rack and pinion type steering device that is provided with means for elastically biasing a support yoke toward a rack, a pair of support surfaces are formed in series with the concave surface of the support yoke, and a pair of support surfaces are formed by the support surfaces. A rack and pinion type steering device characterized in that the widest part of the rack along the second direction is supported.
