Summary:Disclosed is a street inlet having a bellows. The street inlet connected to a main drain pipe by a coupler includes: a street inlet body having a rainwater inlet port at an upper portion and a rainwater outlet port at a lower portion of a side, the inner side of the rainwater outlet port being provided with a bellows engaging portion; and a bellows having a cylindrical body inserted in a connecting pipe, a corrugated portion extending from the cylindrical body, and a flange engaged to a rear end of the corrugated portion. The cylindrical body and the corrugated portion are formed to be smaller than an inner diameter of the rainwater outlet port, and the flange is formed to be larger than the inner diameter of the rainwater outlet port. The bellows is inserted in the rainwater outlet port in the street inlet body, and then the flange is engaged to the bellows engaging portion by bolts, thereby easily installing the street inlet by freely moving the rainwater outlet port inside the street inlet body. 자바라를 구비한 빗물받이가 개시된다. 개시된 빗물받이는 연결관에 의해 하수본관과 접속되는 빗물받이에 있어서, 상부에 빗물유입구와 측면하부에 빗물유출구를 구비하며, 상기 빗물유출구의 내측부에 자바라결합부가 매립설치된 빗물받이본체; 상기 연결관에 삽입되는 원통몸체와, 상기 원통몸체에 연장되는 주름부와, 상기 주름부의 후단에 결합설치되는 플랜지부로 구성된 자바라;를 포함하며, 상기 원통몸체와 상기 주름부가 상기 빗물유출구의 내측 직경보다 작도록 구성되고, 상기 플랜지부는 상기 빗물유출구의 내측 직경보다 크도록 구성되어, 상기 자바라는 상기 빗물받이본체의 내부에서 상기 빗물유출구에 삽입된 후, 상기 플랜지부가 상기 자바라결합부에 볼트체결방식으로 결합되도록 구성되는 것을 특징으로 한다.
