A gasket for connecting a duct of a connecting duct is provided to smooth the flow of the air by preventing the deformation of a body due to a vertical support part. A gasket for connecting a duct of a connecting duct comprises a body and a step groove part(15). The body has a flow-through hole(12) and is made to correspond to the cross-sectional shape of the connection duct(20). One or more supporting part is perpendicularly installed at the flow-through hole center into one body to prevent the droop of the body. The step groove part is formed at the outer circumference of the body one side. The step groove part forms an assembly space part between the step groove part and the connection duct. The assembly space part is recess type to insert and connect the duct.
