Accelerator operating device

An accelerator operating device positioned on a handlebar, the accelerator operating device comprising:

• a body fixed to the handlebar;
• an accelerator lever that is supported on the body so as to rotate freely around a predetermined axial line and that rotates between a close position and a maximum open position;
• a first return spring that returns the accelerator lever to the close position;
• and
• a load generation mechanism that generates a load on a rotational operating force of the accelerator lever by frictional resistance,
• wherein the load generating mechanism includes
• a pair of rotational sliders that are arranged to freely rotate around the axial line and that can be pressed and rotated by opening rotation of the accelerator lever,
• a slide receiving part that is formed in the body and that makes contact respectively with and allows the pair of rotational sliders to slide, and
• a second return spring that returns the pair of rotational sliders to a rest position corresponding to the close position,
• wherein one of the pair of rotational sliders includes a first inclined surface having a predetermined angle against the sliding direction and the other of the pair of rotational sliders includes a second inclined surface being contacted to the first inclined surface,
• the pair of rotational sliders includes a pair of sliding parts that are respectively contacted to the slide receiving part, and
• the pair of sliding parts are configured that distance therebetween becomes large due to relative movement of the first inclined surface and the second inclined surface in opening rotation direction in accordance with the rotation of the pair of rotational sliders being pressed by the opening rotation of the accelerator lever.
