The present invention relates to a deceleration caster device. The device has a shaft moving hole in a form of a longitudinal elongated hole formed in a caster housing member, a deceleration gear member, and a wheel rotation gear member having a diameter larger than that of the deceleration gear member is provided on a caster wheel member where a wheel rotation shaft is coupled through the shaft moving hole to allow the wheel rotation gear member to engage with the deceleration gear member as the wheel rotation shaft moves upward in the shaft moving hole when a load is applied from an upper side of the caster housing member. Accordingly, the rotation of the caster wheel member is decelerated to restrict movement, and movement in a short distance is allowed to improve user convenience.

    본 발명은 감속 캐스터 장치에 관한 것으로, 캐스터 하우징부재에 세로방향의 장홀 형태의 축이동구멍을 형성하고, 감속기어부재를 장착하며 바퀴 회전축이 상기 축이동구멍을 관통하여 결합되는 캐스터 바퀴부재에 상기 감속기어부재보다 큰 직경을 가지는 바퀴회전기어부재가 구비되어 상기 캐스터 하우징부재의 상부 측에서 하중이 가해지면 상기 바퀴 회전축이 상기 축이동구멍 내에서 상부로 이동하여 상기 바퀴회전기어부재가 상기 감속기어부재로 맞물리게 함으로써 상기 캐스터 바퀴부재의 회전이 감속되어 이동이 제한되고, 짧은 거리의 경우 이동이 가능하여 사용자의 편의성을 크게 향상시킨다.
