Claims (1)

[Claims for Utility Model Registration] (1) In a plurality of printed circuit board support parts formed on a metal chassis base, at least one of the support parts is plate-shaped and has a height of H ₁ from the metal chassis base. A fixing part main body is installed upright, a mounting part parallel to the base surface is provided on the side surface of the distal end of the fixing part main body to constitute a first support part, and a printed circuit board is attached to the mounting part with a screw passing through the printed circuit board. The printed circuit board fixing section at the other location is fixed on one support part, and the other printed circuit board fixing section is attached to the upper end of the main body of the fixing section at the height _H1 , which is set upright on the chassis base, at the same height as the height _T1 of the printed circuit board. SaH ₂
And, a neck portion formed with a width W ₂ narrower than the width W ₁ of the fixing part main body is continuously provided, and the width W ₃ is approximately the same as the neck portion from the tip of the neck portion in the same direction with respect to the chassis base surface. _A base with a width of
₄ with W ₄ > W ₃ , the large head portion and the base form a retaining portion, the retaining portion, the neck portion, and the main body of the fixing portion constitute a second support portion; The printed circuit board facing the part has a fitting hole through which the retaining part can pass, and is composed of a fitting hole base and a large part of the fitting hole head, and the fitting hole head has a shape similar to that of the shear sheet. The fitting hole base is adapted to the large head portion of the base, and the length L ₂ of the fitting hole base is longer than the length L ₁ of the base, and the width W ₅ is W ₅ < with respect to the width W ₄ of the large head portion. W ₄ , and the base end of the fitting hole base is configured in relation to the neck position of the fixing part main body, and when a plurality of second support parts are provided, the second support parts are formed in the same direction. The printed circuit board is mounted by placing it on the mounting part of the first support part, and the printed circuit board is fixed in a pinched manner between the upper end of the fixing part main body and the lower surface side of the head part in the second support part. A fixed structure for printed circuit boards featuring: (2) Provide four printed circuit board support parts on the metal chassis base, consisting of one first support part and three second support parts, and these first support part and second support part A fixed structure for a printed circuit board according to claim 1, which is formed by integrally pressing a metal chassis base with a metal chassis base.
