CONSTANT SPEED TRAVEL CANCELING MECHANISM FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To compactly dispose a constant speed travel canceling mechanism and simplify its structure. SOLUTION: A pair of right and left brake pedals 41 for operating right and left axle brakes either singly or at the same time are pivotally supported against a machine body having a continuously variable transmission and the pair of right and left axle brakes, and a constant travel device is provided for controlling the continuously variable transmission to cause the machine body to travel at constant speed. The constant speed travel canceling mechanism 9 is provided for canceling the constant speed of the constant speed travel device when the right and left brake pedals 41 are operated at the same time. The canceling mechanism 9 has an operating member 26 pivotally supported via a transverse shaft P4 located near and parallel to the operating shaft 52 of each brake pedal 41, and a response means 14 oscillating the operating member only when the right and left brake pedals are operated at the same time is provided between the operating member and each of the right and left brake pedals. The operating member and the constant speed travel device are interlockingly connected together so that actuation of the constant speed travel device is canceled by the oscillation of the operating member 46.
