いる。In another component 140 shown in FIG.
46 is curved in an S-shape. This web 146 also extends from the outer edge area 142 to the central inner area 144. The inner area likewise has a central hole 138 for accommodating the additional part 36 of the electric motor 14. Component 144
Edge region 142 is clamped between casings 22,24. This web 146 is also formed on the same principle as the web 46 of the component 40. Also in this embodiment, the first radius 150 passing through the transition 148 from the outer edge area 142 to the web 146 is relative to the second radius 154 passing through the transition 152 from the inner area 144 to the web 146. It is arranged as follows. That is, the two radii 150, 154 are spaced apart, and these radii 150, 154 are similarly arranged at an angle α to one another. The component 40 or 140 is preferably made of a resilient material, for example spring steel. It has been found that certain synthetic resins are most suitable for compensating the reaction moment of the motor when switching the flow angle and preventing the transmission of unwanted vibration noise. by this. In order to detect that the rotating part comes into contact with the casing, the blowers 14 and 18 are connected to the blower rotation axis (motor shaft 1).
6) It has shoulders 60 and 62 which are opposite to each other in the direction.
Opposed shoulders 68, 70 of casings 20, 22, 24 are arranged corresponding to these shoulders 60, 62. This is particularly advantageous when the vehicle is traveling on bumpy roads and the blowers 14, 18 start to jump and get caught on the component 40.In either case, an easily assembling and inexpensive noise attenuating device is obtained. . This is because the noise attenuator is formed by the disc-shaped component 40 or 140. The disc-shaped component has its outer edge area 42 or 142 held by the casing, and its inner area 44 or 144 is connected to the blowers 14 and 18, respectively, and this outer edge area The inner region and the inner region are connected via a number of elastic webs 46 or 146 which are circumferentially spaced from each other.
