PURPOSE: Grating with a flowing water passage is provided to prevent an offensive odor from flowing backward, and to rapidly discharge flowing water. CONSTITUTION: Grating comprises a flowing water passage, support plates(10), and operating and sealing plates(16). The flowing water passage is formed by coupling protrusions(11), and guide flowing water in an uniform direction within flowing water holes(3). The support plates are fixed to the bottom surface of a grating body(1), and securely support the grating body. The operating and sealing plates are adhered to the bottom surface of the flowing water holes, and prevent an offensive odor from flowing backward using torsion springs(20).
