Claims

[Claims for Utility Model Registration] (1) A control valve consisting of a ventilation window formed in the shroud wall and a flapper covering the ventilation window and having a support shaft, the flapper being opened from the lower side of the ventilation window. The upper portion of the shroud wall is connected to the support shaft through a support shaft, and the portion of the shroud wall that supports the support shaft is integrally formed with a slit hole and a bearing portion that supports the support shaft adjacent to the slit hole. A mounting structure for a control valve in a fan shroud. (2) The mounting structure for a control valve in a fan shroud as set forth in claim 1 of the utility model registration, wherein the slit hole is approximately U-shaped. (3) The bearing section is comprised of a first bearing section provided inside the substantially U-shaped slit hole and a second bearing section provided outside the substantially U-shaped slit hole. A mounting structure for a control valve in a fan shroud as set forth in claim 2 of the utility model registration claim. (4) The mounting structure for a control valve in a fan shroud as set forth in claim 1, wherein the bearing portion is made of an elastically deformable material.
