The present invention relates to a non-powered rainwater filtering device. According to the present invention, various foreign substances included in rainwater flowing in during rainy weather are filtered by a first filter unit provided in a filter housing, some of the foreign substances are discharged to a rainwater pipe, and the remaining part thereof is guided to a rainwater storage tank. Primarily filtered rainwater guided to the rainwater storage tank is moved to the rainwater storage tank after being filtered again through a second filter unit. Therefore, the non-powered rainwater filtering device effectively increases purification efficiency by filtering rainwater in a double layer, significantly reduces maintenance costs by purifying rainwater without power, and does not require frequent maintenance in accordance with corrosion or damage as the filtering device does not include electronic devices. 본 발명은 무동력 빗물 여과 장치에 관한 것으로서, 우천시 유입되는 빗물에 포함된 각종 이물질을 여과하우징에 마련된 제 1 필터부로 여과하여 일부는 우수관로로 배출하고 나머지 일부는 빗물저류조로 안내되도록 하고, 빗물저류조로 안내되는 1차 여과된 빗물을 제 2 필터부를 통해 재차 여과한 후 빗물저류조로 이동되도록 함으로써, 이중으로 빗물을 여과시켜 정화효율을 효과적으로 높이고 무동력으로 빗물을 정화하여 유지비용이 대폭 절감되며, 여과장치에 전자기기가 포함되지 않아 부식이나 파손에 따른 빈번한 유지보수가 필요없는 효과가 있다.
