In this study, structural and fatigue analyses of the motor gears that control the height of car seat were carried out at angles of $10^{\circ}$, $20^{\circ}$, and $30^{\circ}$. The study aims at examining which angle of the gear is superior in terms of effect on strength. In the structural and fatigue analyses, the force of 3136 N was applied to the gears, and the stress and deformation were obtained. As the analysis results, model B ($30^{\circ}$) is suggested to have the best strength and fatigue durability among the three models.
