The present invention relates to a clearance prevention device to absorb clearance / impact in an axial direction and a radial direction of a worm shaft in a motor-driven power steering to support power given to a steering wheel when steering with a motor. The present invention provides a clearance prevention device for a motor-driven power steering, which reduces a frictional force, stabilizes rattle performance, reduces a production cost and a weight, and minimizes a package by realizing a new type of a clearance prevention means capable of controlling clearance in a radial direction and an axial direction of the worm shaft and absorbing a shock by applying an elastic bush having a support force control void in a radial direction and an axial direction to absorb clearance / impact in a radial direction and an axial direction of the worm shaft of an MDPS reducer.

    본 발명은 조향 시 스티어링휠에 들어가는 힘을 모터로 보조하는 전동식 파워스티어링에서 웜샤프트의 축방향 및 경방향 유격/충격을 흡수해주는 유격방지장치에 관한 것이다. 본 발명은 MDPS 감속기의 웜샤프트 경방향 및 축방향 유격/충격 흡수를 위해 경방향 및 축방향 지지력 조절 보이드(Void)를 구비한 탄성 부시를 적용하여, 웜샤프트의 경방향 및 축방향 유격 조절 및 충격 흡수가 가능한 새로운 형태의 유격방지수단을 구현함으로써, 마찰력 축소 및 래틀성능 안정화는 물론, 원가 및 중량을 절감할 수 있고 패키지 최소화를 도모할 수 있는 전동식 파워스티어링의 유격방지장치를 제공한다.
