REGULATING LEVER FOR OPERATION OF WORKING APPARATUS

Japanese Patent JP3474014

B2

PURPOSE: To make a throttle lever independent from operating physical force regardless of a common spring by forming a spring portion sectioned between a support part, and a throttle lever and an operating lever on a function, and abutting on a supporting part of a handle when a spring in a load condition.
CONSTITUTION: A spring 3 is effectively sectioned into two spring portions 4, 5 so as to tightly fit a connecting part 6 of the spring 3 to a fulcrum 21 in the case where a load is applied, and the spring part 4 is arranged on a throttle lever 1 and the spring part 5 is arranged on an operating lever 2. Each spring is a curved plate spring, and the levers 1, 2 are rockably supported around rotary shafts 14, 15 which are disposed in parallel with each other. When the operating lever 2 is pushed down, the operating lever 2 is rotated around the rotary shaft 15 in an arrow 22 direction, the upper spring part 5 is expanded, and force is applied in a tension direction. The throttle lever 1 is rocked around the rotary shaft 14 in an arrow 23 direction, and the lower spring part 4 is expanded.
