行李房摘要：A rack and pinion type steering apparatus is provided with a rack guide made of synthetic resin. In the outer pe r iphery of the rack guide, peripheral ribs are formed in the direction of its circumference and axial ribs are formed in its longitudinal direction, respectively. The space formed between tho ribs and the inner periphery of a guide bore of the rack guide is t to be generally about the same as the space between a conventional rack guide made of sintered alloy and the inner periphery of the guide bore. As a re s ult, at room temperature, each rib enables the same press performance as the conventional rack guide and the suitable reacting force at steering will be kept. Also at high tem p erature atmosphere, when each rib thermally expands and abuts the guide bore, the outer periphery excluding the portions of the ribs is thermally expanded, thus, thermal creep is prevented and stable engagement of the rack and pinion of the steering apparatus can be maintained at all times.
