Attachment structure of rear panel to tuner

An attachment structure of a rear panel to a tuner, in which a rear panel is attached and fixed onto a front surface of a tuner, the tuner having two connector connection parts protruding in front and a small protrusion with a tapped hole for panel attachment provided in a middle position between the connector connection parts, the attachment structure comprising:

• the rear panel having two holes for inserting the connector connection parts in portions corresponding to the two connector connection parts of the tuner and a small cylindrical part that is formed protrusively to the tuner side in a portion corresponding to the small protrusion with the tapped hole of the tuner;
• and
• a male screw;
• wherein the two connector connection parts of the tuner are inserted into the two holes of the rear panel, and a leading end of the small cylindrical part is brought into contact with a front surface of the small protrusion with the tapped hole of the tuner, and under this state, the male screw is inserted into the small cylindrical part from the front surface side of the rear panel and further a leading end of the male screw is screwed into the tapped hole of the small protrusion with the tapped hole of the tuner, whereby the rear panel is attached and fixed onto the front surface of the tuner,
• wherein the small cylindrical part of the rear panel is formed by burring;
• in a portion of each of the two holes, a part having plural cuts in circular direction of a hole edge is formed by blanking;
• the cuts are bent toward the front side of the tuner thereby to form a peripheral projections part;
• and
• a leading end of the peripheral projection part comes into contact with the front surface of the tuner.
