A dental coupling member related to a first aspect of the invention comprises: a rod having, at one end region, a first coupling part that is coupled to a first attachment part of a first dental tool, and having a screw part at the other end region; and a cylindrical body having, in an inner circumferential surface of one end region, a screwed part into which the screw part is screwed, and having, at the other end region, a second coupling part that is coupled to a second attachment part of a second dental tool. This dental coupling member comprises a different-torque part at the screw part and/or the screwed part, the different-torque part having a different torque for screwing against the other of the screw part and the screwed part. This dental coupling member suppresses the occurrence of loosening between the screw part and the screwed part.
