Abstract
Official abstract text for this publication.
A rack includes a plurality of thin plates laminated with each other, wherein each of the plurality of thin plates is formed with a set of rack teeth, and adjacent thin plates, which are laminated adjacently to each other, of the plurality of thin plates are fixed together such that respective rack-tooth positions of the adjacent thin plates are displaced from each other in axial directions of adjacent sets of rack teeth.
First claim
Opening claim text (preview).
What is claimed is: 1 . A rack, comprising a plurality of thin plates laminated with each other, wherein: each of the plurality of thin plates is formed with a set of rack teeth; and adjacent thin plates, which are laminated adjacently to each other, of the plurality of thin plates are fixed together such that respective rack-tooth positions of the adjacent thin plates are displaced from each other in axial directions of adjacent sets of rack teeth. 2 . The rack according to claim 1 , wherein a plurality of sets of rack teeth are covered with an abrasion-resistant and friction-resistant member. 3 . A rack manufacturing method comprising the steps of: laminating a plurality of thin plates, each of which is formed with a set of rack teeth, with each other; and fixing a plurality of laminated thin plates together such that respective rack-tooth positions of adjacent thin plates, which are laminated adjacently to each other, of the plurality of laminated thin plates are displaced from each other in axial directions of adjacent sets of rack teeth. 4 . The rack manufacturing method according to claim 3 , further comprising the step of: covering a plurality of sets of rack teeth of the plurality of laminated thin plates, respectively, with an abrasion-resistant and friction-resistant member.
