PROBLEM TO BE SOLVED: To realize a low cost and an easy connection work in the connection structure for an adjustable joint and a shaft body. SOLUTION: While one end 4a of a shaft body 4 is fitted to a receiver 12a having the about U-shape section of a yoke 12, a fixing bolt 20 having an angular shaft part with a polygonal section is inserted in the direction almost orthogonal to the shaft body 4, to the position of the receiver 12a near the opening end than the fitting position at the one end 4a of the shaft body 4, and the shaft body 4 is held from both side surfaces by the receiver 12a by the shaft strength of the fixing bolt 20. The shaft body 4 is held between the fixing bolt 20 and the receiver 12a, by abutting one ridge line of the angular shaft body 20c to the upper surface 4a1 of the shaft body 4, by the rotation of the fixing bolt 20. By applying such a constitution, the workability in the connection work is improved, as well as a low cost by the simple structure and the reduction of part number can be realized. |
