An interval between adjacent blowout ports 005 is disposed at a longer direction dimension of the blowout port 005 or less. Since at least two or more of the blower units 001 are installed around a predetermined space 001a, on the downstream of the blowout port 005, uniform air can be conveyed along the longer direction of the blowout port 005.
