Rack bar 10 for transmitting a steering operation to steered wheels while converting a rotational movement of a pinion shaft rotatably connected to a steering wheel into an axial movement, the rack bar being formed by conducting a die forging process on a material having an approximately circular cross section. A pair of face width-enlarged portions 15 is provided at both ends that rack teeth 14 have in face width direction. With this, it becomes possible to ensure face width dimension W of rack teeth 14 larger than outer shape S of a circular cross section of rack main body 13 (material), which results in an improvement of a contact gear ratio between the pinion teeth and the rack teeth.

A method for manufacturing a rack bar having a first rack and a second rack is provided. The first and second racks have an angular positional difference around an axis of the rack bar. The method includes forming a first flat surface and a second flat surface on an outer circumference of a single hollow shaft member, with the angular positional difference being provided between the first and second flat surfaces, and forming the first rack on the first flat surface and the second rack on the second rack surface by press-fitting one or more mandrels into the hollow shaft member in a state in which one or more teeth dies corresponding to the first rack and the second rack is pressed against the first flat surface and the second flat surface.

A steering device includes a rack shaft, a pair of tie rods, a rack housing portion, a pinion gear at one end of the rack housing portion, a first supporting portion to support the one end of the rack housing portion, and a second supporting portion to support the other end of the rack housing portion. The second supporting portion is movable in an axial direction of the rack housing portion from a proper position where the second supporting portion fixes the rack housing portion by being mounted on the vehicle body to an escaping position on the side of the pinion gear. The escaping position is a position where a distance from a tip of the tie rod on the other end of the rack housing portion to the second supporting portion is equal to or longer than twice the length of the tie rod.
