Abstract

PURPOSE:To prevent a vehicle body from being started inadvertently when a PTO is used by releasing the locking function of an accelerator to return the accelerator to idling position, when the operation for stopping the vehicle body is not performed. CONSTITUTION:When a PTO is used, an accelerator lever 16 as an accelerating device D is swung to open an engine throttle. In this case, if a parking lever 19 is not pulled up, a coned disc spring 18 as an accelerating fixing device A will not be pressed by a link level 21 as a connecting mechanism C, and the accelerator lever 16 will be returned by a spring 15 back to the idling position and held at that position since the accelerator lever is not restrained by any force around a swing shaft P. When the parking lever 19 is pulled up, the link lever 21 is rotated forcibly through a connecting cable 20 serving as an operation detector means B of a parking brake 17 to compress the coned disc spring 18. As a result, the accelerator lever 16 can be kept at any operating position against energizing force of the spring 15.
