The present invention relates to a gear box for sliding a seat of a vehicle. An objective of the present invention is to provide a gear box for sliding a seat of a vehicle which maintains a constant engagement state between a worm shaft and a worm wheel nut by installing an O-ring axially giving an elastic force on bosses on both ends of the worm shaft assembled and installed in a housing. The gear box for sliding a seat of a vehicle includes a worm shaft and a worm wheel nut perpendicularly installed in an engaged state in a housing, and transfers a driving force of a driving means to the worm wheel nut through the worm shaft to be slid along a lead screw. An O-ring giving elasticity is installed on bosses on both ends of the worm shaft to maintain the worn shaft by axial elasticity and suppress vibration and shaking during a high-speed operation. Even when an axial hard drop point of the lead screw is reached, a unidirectional stop impact of the work shaft is alleviated to prevent damage to an engaged portion of the worm shaft and the worm wheel nut.

    본 발명은 자동차 시트 슬라이드용 기어박스에 관한 것으로, 그 목적은 하우징내에 조립설치되는 웜샤프트의 양단보스에 축방향으로 탄성력을 부여하는 오링이 설치되어, 웜샤프트와 웜휠너트간의 맞물림 상태가 항상 일정하게 유지되도록 한 자동차 시트 슬라이드용 기어박스를 제공하는 것이다. 본 발명은 하우징내에 웜샤프트와 웜휠너트가 맞물림상태로 직교설치되고, 구동수단의 구동력이 웜샤프트를 통해 웜휠너트에 전달되어 리드스크류를 따라 슬라이딩 되는 차량 시트 슬라이드 장치용 기어박스에 있어서; 웜샤프트의 양단보스에 축방향으로 탄성을 부여하는 오링이 설치되어, 웜샤프트가 축방향 탄성에 의해 유지되고 고속작동시 진동 및 떨림이 억제되며, 리드스크류의 축방향 하드스톱 포인트 도달시에도, 웜샤프트의 일방향 스톱 충격이 완화되어, 웜샤프트와 웜휠너트의 맞물림 부위에 손상이 발생되지 않도록 구성되어 있다.
