[Prior art]

 As shown in FIGS. 3 and 4, the conventional side clutch rod has two compression springs (a) and (b) so as to prevent pushing and pulling at 14 kgf or more to protect the valve on the mission side. Has been done. In the case of "Fig. 3", when the side clutch rod is pushed and pulled by 13 kgf, the side clutch rod compresses 3.5 mm, so that part must be covered by the link ratio of the steering lever, and the operation load becomes heavy. In the case of "Fig. 4", it does not compress even if it is pushed and pulled by a force of 13 kgf, but it compresses when it exceeds 13.2 kgf. In any case, these conventional ones have a complicated structure, require adjustment of the set length of the spring, and are required to have high strength due to eccentricity. Since the parts are large and not suitable for short ones, there are many problems such as uneven load due to pushing and pulling due to uneven adjustment.
