OPERATION LEVER AND GRIP

摘要

Provided is an operation lever adapted to make a blade perform an action other than an up and down action by rotatably a grip around the shaft center of a lever shaft. The operation lever has a lever shaft operable back and forth, corresponding to an up and down action of a blade of a dozer unit, and a grip provided on an upper part of the lever shaft and capable of rotating in a clockwise direction and counterclockwise direction from a neutral position around a shaft center of the lever shaft by a predetermined rotation angle, corresponding to an angle action or a tilting action of the blade. The grip includes a return-to-neutral spring adapted to return the grip from a rotated position to a neutral position, and the rotation angle of the grip in the clockwise direction is set to be different from that in the counterclockwise direction.
