A local air cleaning apparatus comprising: a pair of push hoods (2, 3) each comprising an air flow opening face for blowing out a cleaned uniform air flow and a pair of guides (4, 5), having lengths b1 and b2 respectively, each provided on a side of each of the push hoods (2, 3) comprising the air flow opening face, each of the pair of guides (4, 5) extending from the side of the each push hood comprising the air flow opening face toward a downstream side of the uniform air flow to form an opening face (41, 51) at a downstream-side end portion of the each guide, wherein the pair of push hoods is arranged such that the respective air flow opening faces of the push hoods (2, 3) are opposed to each other; the opening faces (41, 51) of the pair of guides are spaced apart from and opposed to each other so as to form an open region between the opening faces of the respective guides; the cleaned uniform air flows blown out from the respective air flow opening faces collide with each other in the open region to flow out of the open region so as to cause the insides of the guides (4, 5) and the inside of the open region to be a work region having higher cleanliness, for an operator, than other regions; wherein the guides (4, 5) are configured to increase the work region while maintaining the higher cleanliness within the work region by enabling a distance X between the air flow opening faces with having the guides (4, 5) to be greater than a distance therebetween without having the guides (4, 5) on the sides of each of the air flow opening faces, wherein the lengths b1 and b2 are in accordance with the distance X between the air flowing opening faces. a pair of push hoods (2, 3) each comprising an air flow opening face for blowing out a cleaned uniform air flow and a pair of guides (4, 5), having lengths b1 and b2 respectively, each provided on a side of each of the push hoods (2, 3) comprising the air flow opening face, each of the pair of guides (4, 5) extending from the side of the each push hood comprising the air flow opening face toward a downstream side of the uniform air flow to form an opening face (41, 51) at a downstream-side end portion of the each guide, wherein the pair of push hoods is arranged such that the respective air flow opening faces of the push hoods (2, 3) are opposed to each other; the opening faces (41, 51) of the pair of guides are spaced apart from and opposed to each other so as to form an open region between the opening faces of the respective guides; the cleaned uniform air flows blown out from the respective air flow opening faces collide with each other in the open region to flow out of the open region so as to cause the insides of the guides (4, 5) and the inside of the open region to be a work region having higher cleanliness, for an operator, than other regions; wherein the guides (4, 5) are configured to increase the work region while maintaining the higher cleanliness within the work region by enabling a distance X between the air flow opening faces with having the guides (4, 5) to be greater than a distance therebetween without having the guides (4, 5) on the sides of each of the air flow opening faces, wherein the lengths b1 and b2 are in accordance with the distance X between the air flowing opening faces.
