<P>PROBLEM TO BE SOLVED: To provide a combining device with a release preventing structure of mutual combination by unintended twisting force between mutual combination in a combining device in which a pair of combining tools is mutually combined in the mutually separating direction at the respective axial directions by relative rotation to one peripheral direction after concentric mutual approach of the pair of the combining tools, and for combination release, the pair of the combining tools is relatively rotated to the other peripheral direction after mutual approach in the axial direction of the combining tools. Ž<P>SOLUTION: The combining device includes, in one of a pair of cylindrical combining tool bodies 12 having mutually same structures and mutually combined by mutual rotation to one peripheral direction after concentrically axial direction approach, a band shaped release preventing member 112 disposed movably between a separation position from the outer peripheral surface of the main bodies and a position along the outer peripheral surface, and inserting a release preventing protrusion 118 in a gap between a fitting protrusion 14 of one of the main bodies and a fitting recession of the other body to which it is inserted along the outer peripheral surface in mutual combining in order to prevent rotation to the other peripheral direction for mutual combining release and axial movement, and separating the protrusion from the gap in the separation position.
