Claims

[Scope of utility model registration request]

The valve stem of the valve body is arranged eccentrically so as to open the valve due to the pressure of the flushed body when the flushed body passes through the flow path, and the valve closes when the flushed body does not pass, thereby preventing backflow of odor. 1. An odor prevention valve characterized in that a biasing means is provided for biasing the valve body in a direction to close a flow path in order to prevent odor prevention.
