小さく設定されている。 Figure 2 a and b show the locking protrusion 1 on the joint key 4.
1 shows the assembly process for attaching. First, a piano wire is inserted from the split groove 12 through the support hole 14 of the joint key 4 into the caulking part 13, and one end on the split groove 12 side is bent into a ring shape to form the protruding portion 11a. Part 11a is divided into grooves 12
After inserting it until it hits the base of the crimping part 13, the other end protruding from the caulking part 13 is cut and crushed to form a retaining collar part 11b. Then, the end portion of the inner 3a is inserted into the crimping stop portion 13 and crimped. As a result, as shown in FIG.
The locking protrusion 11 is cantilevered and bent with the part fixed to the support hole 14 as a fulcrum. The protruding portion 11a comes to protrude and retract from the split groove 12. Here, the height a of the protruding portion 1a is set to be equal to the height b of the split groove 12, or the height a of the protruding portion 11a is set to be slightly smaller than the height b of the split groove 12.

As explained above, according to the present invention, in the connection work between the driven gear shaft and the deflection shaft,
If the connecting protrusion is inserted into the connecting recess without alignment, and then relative rotation is applied between the two, the locking protrusion will naturally engage the locking groove due to its elasticity. Work efficiency improves. In addition, during connection work, even if the positions of the locking groove and the locking protrusion are not aligned, unreasonable force will not be applied to the connection part, and the connection part between the inner flexible shaft and the joint key will not bend. , there will be no inconveniences such as damage to the threads of the end nut. moreover,
Since the locking protrusion is formed of a cantilever-shaped elastic material, there are various effects such as the number of parts is small, the structure is simple, and it can be manufactured at low cost.
