ABSTRACT:
A throttle lever device for a small-sized vehicle includes an operating lever which is rotated manually about a pivot shaft to pull or return a cable connected to a throttle valve in a fuel supply unit such as a carburetor. The throttle lever device includes a first link adapted to rotate about the pivot shaft of the operating lever in accordance with the pivotal motion of the operating lever, and a second link supported rotatably through a shaft on a front end side of the first link. One end portion of the second link is engaged with the cable. The first link has a restricting portion for restricting the rotation of the second link. A stopper member disposed in the rotating direction of the second link is adapted to abut the second link. The amount of cable pulled changes relative to the amount of operation of the operating lever which controls the throttle valve.
