  • the distance 11b is equal to or smaller than the distance 7a between the blower fan 5 and the air guider 7. It is desirable to do. The reason is that by setting the distance lib to be equal to or less than the distance 7a, the blower fan 5 and the rubber pushing 11 collide with each other before the collision between the blower fan 5 and the air guider 7 due to swing, so that the blower fan 5 and the air guider This is because the collision with 7 is indirectly avoided by the rubber pushing 11.
  • the horizontal distance 11a may be equal to or less than the distance 7a. This is because the form of the blower fan 5 is not limited to the form shown in the figure, but is various. Further, since the swing form due to the vibration impact also varies depending on the direction of the impact, the horizontal distance 11 a is reduced to the distance 7. By setting the value of a or less, the air guider 7 can be more reliably protected from damage due to collision.
