「下側側部係止受部」[Claims for Utility Model Registration] The three-point link 16 is rotatably connected to the tractor 10 at its front end, and the frame body 22 is connected to the upper central engagement pin 50 at the center of the working machine 34 and the lower side engagement pins on the left and right sides. Upper center pin receiver 2 that receives the stop portions 52, respectively
A telescopic transmission shaft 28 is rotatably connected to the rear end of the three-point link 16 and has a lower side locking receiving portion 26 , and is connected to the PTO shaft 14 of the tractor 10 at the front end. The input shaft 42 of the working machine 34 is connected to the input shaft 42 of the working machine 34 via the front universal joint 30, and the working machine side yoke 70 of the rear universal joint 66 is separably connected to the input shaft 42 of the working machine 34 at the rear end via the rear universal joint 66. is provided with a tapered portion 80 that is separably spline-fitted to the input shaft 42 of the working machine 34 on the inner circumferential side and guides the input shaft 42 to the inner circumferential side of the working machine side yoke 70. 80 and the working machine side yoke 70 are supported by the support member 32 so as to be freely displaceable back and forth, left and right, and up and down, and are urged backward and upward by the rear biasing member 88 and the upward biasing member 106, and are biased backward and upward by the stopper. 58
, 90 restricts backward and upward movement. The brief description of the drawing has been amended as follows. "Lower locking receiver" on page 18, line 15 to line 16 of the specification is corrected as follows. "Lower side locking part"
