Claims

[Scope of Claim for Utility Model Registration] ■ In a tractor in which a mast 15 with a cross-sectional opening is obliquely installed at the rear of the machine body 1, and a hydraulic cylinder 13 for raising and lowering the lifting rod 1F and the 1F is accommodated in the mast 15, this hydraulic The rear inner surface 1 of the mast 15 is attached to the tip of the rod 16 of the cylinder 13.
In addition to rolling rollers 20 and 20 on the mast 15, rollers 23, . . .
A telescopic guide structure for a hydraulic cylinder in a tractor, characterized in that a telescopic guide mechanism 24 for rolling is provided. ■ A potentiometer 33 that detects the amount of expansion and contraction of the rod 16 of the hydraulic cylinder 13 and a connecting link 34 of the link mechanism 27 that constitutes the position control device 26 are respectively connected to the expansion and contraction guide mechanism 24 and housed in the mast 15. A telescopic guide structure for a hydraulic cylinder in a tractor according to claim 0 of the registered utility model.
