PROBLEM TO BE SOLVED: To provide a door handle device for a vehicle which can perform outputs of detection signals to a driving control section and driving of driven members at the same time without increasing the number of connection lines between the door handle device and the driving control section.;SOLUTION: A sensor IC 30 connected to a drive ECU 60 as intervening a first and second electric wires W1, W2, a constant current circuit 37 which is connected to the drive ECU 60 as intervening the first and second electric wires W1, W2, and draws in current from the drive ECU 60, an LED 40 which is connected to the constant current circuit 37, and is driven by current that the constant current circuit 37 draws in, a first switch 38 where switching control is done by a switch control section 30b of the sensor IC 30, and which makes the current that the constant current circuit 37 draws in fluctuate selectively to output detection signals from the sensor IC 30 to the drive ECU 60, and a second switch 39 where switching control is done by the switch control section 30b, and makes the current that the constant current circuit 37 draws in toward the LED 40 fluctuate selectively are comprised.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
