PROBLEM TO BE SOLVED: To provide an accelerator operating switch for an engine-assisted saddle-riding type vehicle which has high durability and detection accuracy and downsizing is realized.SOLUTION: An accelerator operating switch is equipped with: an accelerator grip 12; a magnetic field generating section 13 supported by an accelerator grip; and a sensor 14 for detecting the magnetic field supported by a handlebar 11. The magnetic field generating section is made up of a magnet 16 and a yoke 17, the magnet is magnetized in two poles in a rotational axis direction of the accelerator grip, and the magnetic pole 16a is arranged so as to face a sensor side. One end 17a of the yoke is brought closer or connected to the magnetic pole 16a, and the other end 17b is brought closer or connected to a magnetic pole 16b. One end 17a of the yoke and the magnetic pole 16a are arrayed in a moving direction of the accelerator grip, and a detection point 14a of the sensor crosses a boundary surface 20 between one end 17a of the yoke and the magnetic pole 16a of the magnet immediately before the accelerator grip is fully closed. When the accelerator grip is fully closed, the magnetic pole 16a faces the detection point 14a of the sensor. |
