To provide a space-saving composition, and easy detachment without requiring a great amount of costs in a support bolt joint having a bolt, and a mechanism for fixing the bolt to a hole part of a machine element.
The bolt 12 of the support bolt joint 10 has a columnar center part 18, and two conical tapered end parts 20. The mechanism 14 for fixing the bolt comprises two diametrally expandable bushes 22 having inner circumferential faces substantially corresponding to the tapered end parts 20 of the bolt, which can be fastened in an axial direction by a fastening means, and diametrally expanded outward in a radial direction of the hole part of the machine element 16. The support bolt joint is characterized by that the diametrally expandable bush 22 has a connection area 26 in an end part in an opposite side to the bolt 12, and a sleeve 28 for drawing can be loosely connected to the connection area 26.
