SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a main body in which a strip-shaped steel plate is curved in a ring shape, and the start and end of the main body are opposed to each other with a predetermined gap. A coupling portion formed as described above, and a mounting portion for mounting the main body portion to the mounting portion, a gap between the coupling portion by pressing the coupling portion in the same direction as the axial direction of the cylindrical capacitor and The configuration is such that a taper is provided that moves so as to reduce the diameter of the main body.

According to the present invention, since the main body of the capacitor mounting device can be fixed by tightening in the same direction as the axial direction of the capacitor, workability is adversely affected even when a plurality of capacitors are arranged adjacently. Work can be performed easily and reliably.
