The purpose of this study is to find structural factors affects the rattle noise and to investigate the relationship of these findings in the car seat rail .We used each 30 per three variables, such as x-axis freeplay, y-axis characteristics and rattle noise, the moderating effect analysis was performed with this data to prove our hypothesis. Results, rattle noise was occurred due to impact between a lower rail and a locking device of rail when a vehicle was vibrating (x-axis freeplay), it has been found that side stiffness (y-axis characteristics) control the impact.
