Abstract
Disclosed is a rack and pinion mechanism used in a steering device of a vehicle, in which when a pinion is engaged with rack teeth at an axially middle part of a rack bar, the rack bar is supported by supporting surfaces of a support yoke in the form of surface contact. When the pinion is engaged with the rack teeth at a part other than the axially middle part of the rack bar, on the contrary, the rack bar is supported by a rotary bearing mounted on the support yoke. Therefore, when a vehicle runs rectilinearly, the sliding resistance of the rack bar becomes large and the handle is stabilized, while when the vehicle turns, the sliding resistance becomes small and handling is made light because the rack bar is supported by a bearing.
