Zusammenfassung:PROBLEM TO BE SOLVED: To provide a rotational torque detection device mainly used for detection of a rotational torque of a vehicle steering or the like, capable of detecting the rotational torque inexpensively and surely. SOLUTION: An approximately cylindrical magnet 12 fixed to a first rotator 11 is formed in the state where different magnetic poles are arrayed adjacently, and a groove part 13 is provided between the magnetic poles, and thereby a volume of the magnet 12 is reduced as much as a portion of the groove part 13 formed between the magnetic poles, and a using amount can be reduced. Consequently, this rotational torque detection device capable of detecting the rotational torque surely with an inexpensive constitution can be acquired. COPYRIGHT: (C)2011,JPO&INPIT
