Claims

[Scope of utility model registration request]

There is a grounding line that directly grounds the motor line led out from the blower motor, a resistance line that grounds the motor line via a resistance, and a position changer depending on whether internal air is being circulated or outside air is being introduced. A vehicle air conditioner that is operated by a variable member and has a switching member that connects a motor line to a ground line when outside air is introduced, and connects the motor line to a resistance line when inside air is being circulated. Device.
