2. Description of the Related Art Heretofore, in this type, the following has been done. 1. In the conventional plug-in type ventilation opening, in order to maintain the strength of the short pipe in the duct insertion part, the tip of the inner part is bent inward. 2. There is a considerable gap between the short pipe and the duct at the insertion part. 3. A large amount of caulking agent is used to prevent the exhaust gas from leaking from other than the ventilation port. 4. The duct is inclined so that rainwater or the like can be discharged to the outside from the outer wall.

Since the trumpet-shaped tip portion 2B to be located outdoors is formed in the cylindrical body 2A, the following effects can be expected. A. Since the tip of the exhaust duct is protruding from the outer wall, it is difficult for building wind, etc. that travels through the wall to enter the exhaust duct. B. Since the one according to the present application is mounted slightly out of the outer wall, the rainwater and dew condensation water that has entered will fall apart from the outer wall. That is, the rainwater or the condensed water that has entered the exhaust duct portion smoothly flows out of the outer wall without being hindered by the bending of the short pipe insertion portion or the caulking agent. 3. When the ventilation opening 4 with a windbreak plate is provided, building wind or the like that propagates through the wall escapes to the upper part, so it is difficult to enter the exhaust duct part. 4. In the case of the ventilation opening 5 with a hood, it is difficult for rain or snow to enter from above. 5. In the case where the chamber is provided, the rainwater and the condensed water that have entered are stopped in the chamber, and it is more difficult to enter the inside and easily exits to the outside. 6. When the ventilation duct mounting vertical plate portion cannot be attached to the exhaust duct portion, as in the case where the exterior is made of a thick brick, the construction having the L-shaped metal fitting can facilitate workability.
