PROBLEM TO BE SOLVED: To lead air in a wide sphere efficiently to an intake part. SOLUTION: An air sending part 20 having a fan 22 opposed to an intake part 15 of a main body part 10a is disposed with a prescribed space to the main body part 10a. A passage of air directed from the fan 22 toward the intake part 15 is formed. In this case, the atmospheric pressure in the passage of air becomes lower relatively than the surrounding air and the air in the vicinity gathers to this passage of air. Thereby the air in a wide sphere is led sufficiently to the intake part 15. |
