Summary:The present invention relates to a low-noise tennis practice device with a variable inclination angle, which is capable of simply adjusting a release angle of a rebounding tennis ball. According to the present invention, the low-noise tennis practice device with a variable inclination angle comprises: a plurality of elastic members including a frame which includes a pair of side members spaced apart and disposed in parallel and a connection member connecting the pair of side members, and a wire mesh which is disposed in a space surrounded by the frame in a tensioned state, and disposed at a different inclination to rebound a tennis ball hit by a user by a plurality of times and return the same toward the user; and a rotary shaft rotationally connecting a side surface member of the pair of adjacent elastic members. Moreover, a gap between the pair of side surface members is differently set to place any one of the pair of elastic members between the side surface members of the other elastic member. 본 발명은 가변 경사각을 갖는 저소음형 테니스 연습장치에 관한 것으로서, 본 발명에 따른 가변 경사각을 갖는 저소음형 테니스 연습장치는 나란하게 이격 배치되는 한 쌍의 측면부재와 상기 한 쌍의 측면부재를 연결하는 연결부재로 구성된 프레임과, 상기 프레임으로 둘러싸인 공간에 인장된 상태로 배치되는 와이어 메쉬로 구성되고, 사용자가 타격한 테니스공을 복수 회 튕겨내 사용자를 향해 복귀시킬 수 있도록 서로 다른 기울기로 배치되는 복수의 탄력부재; 및 인접한 한 쌍의 탄력부재의 측면부재를 회동 가능하게 연결하는 회전축;을 포함하며, 인접한 한 쌍의 탄력부재의 프레임은, 어느 하나의 탄력부재가 다른 하나의 탄력부재의 측면부재 사이에 위치할 수 있도록, 한 쌍의 측면부재의 사이간격이 서로 다르게 설정되는 것을 특징으로 한다.
