PURPOSE:To prevent invasion of rainwater on the above heading construction of air conditioning system for motorcars, by providing a cooling wind inducing room which is connected with the inside of a fan scroll through a passage hole on the side wall of the scroll, and also is connected with a fan motor through a cooling pipe at the position vertically upward of the passage hole. CONSTITUTION:A cooling wind inducing room 23 is integrally made on the side wall 21 of a fan scroll 5, and is connected with the inside of the scroll 5 through a passage hole 15a, and is also connected with the inside of the fan motor through a cooling pipe 17a. Here, the outlet 25 of the cooling pipe 17a is made at vertically upward possision of the passage hole 15a. Owing to this constitution, the air containing rainwater in the fan scroll 5 is reduced when induced into the cooling wind inducing room 23 from the passage hole 15a, and the contained rainwater is separated, thus the cooling wind not containing rainwater is sent to the fan motor through the pipe 17a. |
