PROBLEM TO BE SOLVED: To provide a mounting device capable of engaging two objects with each other so that their facing positions after the engagement are always in predetermined facing positions and securely detachably engaging them with each other by a simple operation. SOLUTION: When the objects are engaged with each other (before the engagement), i.e., the two semi-circular parts of a drive part 1 are fitted to each other, a space chamber 4 comprises a space of such a size minimally required for storing a cam 2. When the cam 2 is rotated, the space chamber 4 storing the cam 2 is pushed open to move the right and left side semi-circular parts of the drive part 1 having the space chamber 4 in the directions that they are separated from each other, and the drive part 1 comes into contact with the inner wall of a female screw 6 (first object) at least at two positions on the outer peripheral surface of the drive part 1. The contact pressure is increased according to the rotation of the cam 2, and when the rotation of the cam 2 reaches a predetermined rotating angle (for example, 90°), the drive part 1 is engaged with the female screw 6 (second object) with a maximum strength.
