Abstract
A throttle opening detection device includes a rotor which is rotated in an interlocking manner by manipulation of an acceleration grip which is mounted together with the rotor on a handlebar. First magnets are arranged near a peripheral portion of one side surface of the rotor along the circumferential direction of the rotor, while second magnets are respectively laminated to the first magnets, and have opposite polarities to the first magnets. The first magnets with the second magnets laminated thereto are disposed with a set spacing therebetween. A magnetic sensor for detecting a magnetic force generated by all the magnets is arranged to oppose, with a clearance therebetween, the one side surface of the rotor in which the magnets are arranged, in an axial direction of the rotor.
