摘要：
A wiper system 1 has wiper blades 4a and 4b driven by a wiper motor 7 and washer nozzles 16 for ejecting washer liquid in association with operation of a washer motor 18. The wiper motor 7 and the washer motor 18 are drive-controlled by a controller 9 housed in a motor unit 6. The controller 9 uses a FET module 10 for a three-phase motor provided with seven FETs. In the FET module 10, a battery reverse connection protection part 31 is provided with one FET (34a), a wiper motor drive part 32 is provided with four FETs (34b to 34e), and a washer motor drive part 33 is provided with two FETs (34f and 34g).
