Abstract: A blowing device includes a passage member and a passage switching device. The passage member is inserted into an air passage configured to blow a main air into the vehicle cabin. The passage member is configured to blow an added-value air. The passage member includes, in the air passage, a passage opening portion through which the added-value air is blown toward a passenger separately from the main air. The passage member defines a hole portion and the passage switching device is a damper or a rotary door. The damper or the rotary door closes the hole portion to allow the added-value air to flow out through the passage opening portion and fluidly connects the hole portion to the air passage to allow the main air to flow out through both the passage opening portion and a region of the air passage other than the passage opening portion.

Abstract: An airflow generating device includes an airflow generating portion, a duct, and a controller. The airflow generating portion is configured to generate an airflow. The duct is configured to guide the airflow to a blowing outlet through which the airflow is blown out toward a passenger in a vehicle cabin. The controller is configured to cause the airflow to be intermittently blown out through the blowing outlet by controlling a frequency of a pulse voltage applied to the air flow generating portion and a duty ratio of a pulse width to a pulse period of the pulse voltage. The controller is configured to control the duty ratio and the frequency of the voltage such that the airflow is blown out through the blowing outlet at a speed between a predetermined lower limit, inclusive, and a maximum lower limit, non-inclusive, which is greater than the lower limit.

Abstract: A vehicular static eliminating device includes: a negative ion generating device; and a guide device configured to guide negative ions and release the negative ions from an emission port to a static elimination target spot which is positively charged, the guide device including: a guide member defining a passage through which to guide the negative ions, the guide member being made of a resin which is easily negatively charged in a triboelectric series; and a tip-shaped part configured to discharge, by corona discharge, negative electric charges, which have accumulated on the guide member, to the static elimination target spot, the tip-shaped part being provided in a part defining the emission port and in proximity to the static elimination target spot.
