PURPOSE: An anti-stench device for a manhole is provided to block the stench from sewage drain and to facilitate inflow of rainwater by opening the bottom of the manhole when raining. CONSTITUTION: An anti-stench device for a manhole comprises a frame(10), a guide plate(30), a drain pan(40), and a hinge(20). The guide plate is formed as inclined surface and guides water which flows from the manhole. The drain pan accommodates the water. The guide plate is rotated downward if the water is filled in the drain pan and blocks the stench by being rotated upward after draining.
