Abstract
A gear having a thin-walled section formed on one end face among two end faces of a tooth in a tooth-width direction is provided. A portion of the thin-walled section is projected and formed so as to serve as an overhanging section. The overhanging section prevents backlash. A thickness T3 of the overhanging section, a thickness T2 of a tooth flank corresponding section, and a thickness T1 of a tooth crest corresponding section positioned therebetween satisfies the relation T1<T3<T2.
