Filed: 1986-02-04
Abstract: PURPOSE:To prevent a gear fracture by providing a means for disengaging pins from coupling holes among an operation slider, the plate part of an operation lever and a bracket at a distance from each other, and shifting a phase. CONSTITUTION:The plate part 16 of an operation lever 14 is made free to turn back and forth and an operation slider 20 is made free to slide, thereby enabling the operation of a stepless transmission. Pins 29 and 30 and coupling holes 31 and 32 are formed on both sides of the operation lever 20, the plate part 16 and the inward side of a bracket 28. When the operation slider 20 slides to either direction and the operation lever 14 is moving back and forth, the constitution is so made that the pins 29 and 30 at a distance will be disengaged from the coupling holes 31 and 32 and a phase will be out of order, thereby making it impossible to shift the slider 20 to an opposite direction. Consequently, a driving gear rotating at high speed does not change the gearing thereof with a partner gear, thereby preventing a gear fracture.
