Abstract
A throttle-opening sensor has a detect shaft rotatable about an axis in conjunction with a throttle grip, a pair of rotation terminals respectively disposed on different positions in the same circle with the rotation axis, the pair of rotation terminals being rotatable together with the detect shaft, contact pieces disposed on each of the rotation terminals at predetermined intervals in a rotation-radius direction of the rotation terminal, a printed circuit including conducting pattern portions printed along sliding loci of the contact pieces and, a resistance portion printed in a sliding range of the contact piece of the conducting pattern portion, and generating a resistance against a current flowing in the conducting pattern portion, wherein at least two detection signals variable in mutually opposite directions according to the rotation angles of the throttle grip are generated due to that the contact pieces respectively allow the conducting pattern portions to conduct therebetween.
