PROBLEM TO BE SOLVED: To rigidly couple metal fixings to a mounted object so that a structure is formed rigidly by combining one or a plurality of coupling unit bodies forming a basic configuration according to applications and aligning the mounted objects for the same or different types of products comprising civil engineering materials and construction materials for mounted objects by a simple handling operation. SOLUTION: A fixing unit body J is formed of a case 1 having a sleeve storage hole 3 provided at the bottom of an insert hole 2, a sleeve 4 having a converging spring material 5 fitted to outer peripheries of a plurality of divided component pieces 4A1 , 4A2 , and 4A3 and a locking hole 6 provided in the inner periphery thereof, and stored in the sleeve storage hole, and a connection shaft 7 having a locking part 7 lockably press-fitted into the locking hole to a specified length through a locking means 8. The connection shaft is installed displaceably in the direction crossing a pressing direction A when press-fitted into the locking hole.
