PURPOSE: To make two levers pivotable without a play, related to a device for pivotable linkage between the two levers. CONSTITUTION: One end of a lever 2b has a fork that receives a lever 5b between its crotched part 6a, 6b. Each of the crotched part 6a, 6b has a recess 9 made on its inner face. The recess 9 is parallel to the inner face and extends in the longitudinal direction of the crotched part, thus forming a passage for receiving a pivot 10. The end of the lever 5b has a lateral recess 11 intended to engage the pivot 10. One end of a draw spring 13 has one end secured to the lever 2b, while the other end is fixed in a groove 12 that is concentric with the axis of the pivot 10 and that is made at the end of the lever 5b opposite to the opening of the recess 11. |
