PURPOSE: To hardly transmit vibration to a vibration receiving side by forming four notches in parallel along the circumferential direction on one axial end side, and also diminish parts to be discarded by a trimming working, in the cylindrical member of a mounting device. CONSTITUTION: A circular ring part 20A having L-shaped cross section is formed on one axial end side of the inner cylindrical metal fitting 20 of a strut mount which is a mounting device, and a circular tube part 20B whose diameter is smaller than the ring part 20A is formed at the other end part. Further, the ring part 20A and the circular tube part 20B are engaged with each other by a taper connecting part 20C, and four notches 22 are formed in parallel at equal intervals along a circumferential direction around the ring part 20A. Drawing is executed under such a condition that parts to be notches 22 are arranged in a position matched to the center of each four corner of a square blank member. At this time, the center parts of four corners of the blank member are hauled on a center side so that the notches 22 are respectively formed accompanying the drawing. After this process, four corners of the blank member are trimmed so as to form holes, and the ring part 20A are machined.
