  • rain water when it rains, rain water can be stored in the rain water storing portion that is provided at the cowl portion. Further, the rain water that is stored in the rain water storing portion is introduced into the cool wind introducing means via the rain water introducing passage. Due the rain water being sent to the cooling unit by the cool wind introducing means, pollution of the cooling unit can be washed by the rain water.
  • a filter for removing dirt is provided at a cowl portion side of the rain water introducing passage.
  • the cooling unit can be washed by rain water from which dirt has been removed.
  • a motor of a compressor that is used in the air conditioner is used as motive power of the blower.
  • the motor of the compressor that is used at the air conditioner is used as the motive power of the blower. Therefore, the number of parts can be reduced as compared with a case in which the motive power of the blower is provided separately from the motive power of the compressor.
  • the cooling unit can be cooled more efficiently.
  • ventilation of the vehicle cabin interior can be carried out due to some of the cooling wind, that is blown by the blower, being introduced into the vehicle cabin interior.
  • the cooling unit can be washed by rain water.
  • the cooling unit can be washed by rain water from which dirt has been removed.
  • the number of parts can be reduced.
