PROBLEM TO BE SOLVED: To provide a joint structure allowing easy and accurate connection between front and rear cylindrical bodies with a flange joint and rotating force on the front cylindrical body to be firmly received by the rear cylindrical body. SOLUTION: A joint portion such as a cone crusher portion of a shield machine is formed by integrally connecting both flanges 3, 4 of the front cylindrical body 1 having an outer cone mounted for receiving the rotating force of an inner cone and the rear cylindrical body 2 consisting of a skin plate with bolts 7. The front and rear cylindrical bodies 1, 2 are joined together by fitting between a circular protruded portion 8 and a circular recessed portion 9 whose centers are offset from the axial centers of the cylindrical bodies. The protruded and recessed portions 8, 9 prevent the operation of the rotating force on the front cylindrical body 1. |
