<p>PURPOSE: To provide a side strut for the lower connecting rod of the three-point device of a tractor for minimizing a bending load resulted from a tensile load or a compression load. CONSTITUTION: A movement stopper 24 is provided so as to dissolve a floating position mutually executable by both nesting members 14 and 15 of the side strut 6 and it clamps and fixes a fixing pin 31 through the fixing contours 29 and 30 of a fixing recessed part 28. The swing shaft of a shaft pin 27 and a contact part between the fixing contours 29 and 30 and the contour of the fixing pin 31 of the two movement stoppers 24 arranged on the side of the nesting members 14 and 15 are on a connection line passing through the swing shaft of a spherical eye 13 parallelly to a sliding shaft 16. Thus, when tensile force or compression force appears, the movement stoppers 24 and the side strut 6 are prevented from being energized by bending moment resulted from it as the whole.</p> |
