。In the case of screw fastening, there is a problem that the position may shift due to vibration shock or environmental temperature changes. SUMMARY OF THE INVENTION The present invention aims to solve these problems, and its purpose is to provide a highly reliable head fixing structure that has a shape that facilitates parts processing, has sufficient head fixing force, and is highly reliable. It is in.

特徴とする。Means for Solving Problem C] In the head fixing structure of the present invention, in an information recording device, the head fixing member has an eyelet-like flange shape, and the flange shape is inserted into the round hole of the member to be fixed to the head. After the part is inserted, a polygonal prism-shaped or polygonal pyramid-shaped punch is press-fitted into the flange-shaped hole of the head to secure it by caulking.

形成するためヘッドが回転しにくく強力な固着力が得ら
れる。According to the above structure of the present invention, the head caulking hole of the member to be fixed to the head is a round hole, which is easy to process, and high precision can be maintained. Moreover, the apex corner of the prismatic or pyramidal punch that is press-fitted inside significantly plastically deforms the head fixing member and the fixed member, creating an arc polygonal caulking boundary surface that prevents the head from rotating and is strong. A strong adhesion force can be obtained.
さらには、ヘッドのフランジ平面方向にずれる心配もな
い為、ネジ止めに比較して、振動や衝撃、温度変化によ
り位置が狂うことがない。Furthermore, since there is no need to worry about the head flange shifting in the plane direction, the position will not shift due to vibration, impact, or temperature changes, compared to screw fixing.

This shows the positional relationship of the punch 1 which is press-fitted into the shape of the flange for fixing the spatula, and the fixing member is brought into close contact with the flange part of the head to be crimped, and the positioning in the direction of the contact plane is performed using a jig or the like, By press-fitting and caulking a square-shaped punch, the flange portion and the head-fixed member are partially plastically deformed at the portion where the apex of the punch comes into contact, thereby forming an arcuate polygonal boundary surface. become.

ることもできる。At this time, even if the punch is press-fitted as a part, there is no practical problem and a strong caulking state can be obtained. Or, as part of the jig, the crimped state can be maintained even if it is removed after crimping.
The punch can be used over and over again, contributing to rationalization of parts costs.

It has the effect of providing a head fixing structure that is strong and does not shift due to external force or temperature changes (high tel properties).
