PURPOSE:To prevent intrusion of water in blower case into the blower motor housing by providing a partition wall for snaking the intake air in vertical direction at the take-in port section of blower case while forming a drainage hole at the lower section of the partition wall. CONSTITUTION:A take-in port 6A is formed between upper and lower blower cases 5A, 5B. Here, plural partition walls 8A-8E for snaking the cold intake air in vertical direction are provided at the intake port 6A. In other words, three partition walls 8A-8C are arranged integrally in radial direction of the blower case 5 on the lower blower case 5B along the cold air flow path while a partition wall 8D placed between the partition walls 8A, 8B and a partition wall 8E continuous with the partition wall 8C are formed integrally on the upper blower case 5A thus to form a snaked cold air path 9. While a drainage hole 10 for flowing out the water stored between the partition walls 8A, 8B into the blower case 5 is formed at one side of the lower section of the partition wall 8A. |
