VEHICLE LIGHT CONTROL GLASS DEVICE

A light control glass is smoothly moved up and down. A vehicle light control glass device (10) of the present invention includes a light control glass (12) that includes a light control layer in which a transmittance changes according to an applied AC voltage, the light control glass (12) being provided in a car body while being able to be moved up and down; and an inverter (14) that includes a power feeding circuit, the power feeding circuit converting a DC voltage output from a battery mounted on a vehicle into the AC voltage and applying the AC voltage to the light control layer, the inverter (14) being provided in a lower portion of the light control glass (12). According to the configuration, the inverter (14) is provided in a lower portion of the light control glass (12), so that a gravity center of the light control glass (12) can be lowered. Accordingly, the light control glass (12) can smoothly be moved up and down.
