PROBLEM TO BE SOLVED: To surely return an accelerator lever to a neutral position with a simple structure even if a spring is nonfunctionally damaged by providing an exciting means exciting the accelerator lever to naturally return to the neutral position on the accelerator lever, and providing a weight on the lower end side across the shaft of the accelerator lever. SOLUTION: An accelerator lever 9 can be longitudinally inclined in the prescribed angle range, and it is set to a neutral position in the erected attitude. A weight 9b is integrally provided on the lower end side opposite to an operation section 9a on the upper end side across a shaft 12. A helical spring exciting the accelerator lever 9 to naturally return to the neutral position is provided around the shaft 12. When the tilt of the accelerator lever 9 is released, it is naturally returned to the neutral position by the excitation of the helical spring and the gravitational force of the weight 9b. Even if the helical spring is broken, the accelerator lever 9 is naturally returned to the neutral position by the gravitational force of the weight 9b on the lower end side. |
