PROBLEM TO BE SOLVED: To provide an instrument unit in which a direction indicator can be down-sized with a simple configuration, and a vehicle.SOLUTION: A direction indicator 5 is located on an instrument unit. A direction indicator drive part 5 comprises a control circuit 10, a lighting control circuit 32, a booster circuit 31, and a switch 11 which is configured from an FET. The booster circuit 31 flows electric current to a current path including an LED 21 of the direction indicator 2. The switch 11 is located on the current path. The control circuit 10 transmits a flashing signal to the lighting control circuit 32. The lighting control circuit 32 responds to the flashing signal and switches on and off the switch 11, thereby conducts/blocks electric current to the LED 21 and performing lighting/lights-out of the LED 21. The lighting control circuit 32 transmits a voltage control signal for stabilizing operation output to the booster circuit 31 thereby stabilizing electric current which flows on the current path.SELECTED DRAWING: Figure 3
【課題】簡単な構成で、方向指示器を小型化可能とする計器ユニット及び車両を提供する。【解決手段】計器ユニットに方向指示駆動部5が配置されている。方向指示駆動部5は、制御回路10と、点灯制御回路32と、昇圧回路31と、FETから構成されるスイッチ11と、を備える。昇圧回路31は、方向指示器2のLED21を含む電流路に電流を流す。スイッチ11は、電流路に配置されている。制御回路10は、点灯制御回路32に点滅信号を送信する。点灯制御回路32は、点滅信号に応答し、スイッチ11をオン・オフすることにより、LED21に電流を通電・遮断させ、LED21を点灯・消灯する。点灯制御回路32は、昇圧回路31に動作出力を安定させる電圧制御信号を送信し、電流路を流れる電流を安定化する。【選択図】図3
