Claim of US Patent No. 10,988,093

1. A vehicular static eliminating device (i) provided in a vehicle on which positive static electric charges accumulate and (ii) configured to eliminate static electricity from a static elimination target spot in the vehicle, the static elimination target spot being predetermined and positively charged, or to negatively charge the static elimination target spot,said vehicular static eliminating device comprising:
a negative ion generating section; and
a guide device configured to guide negative ions generated by the negative ion generating section, and release the negative ions from an emission port to the static elimination target spot,
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 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.
