The fixture 10 is attached to the fixture boss 6 in the state shown in FIG. FIG. 5 is a perspective view of the printed circuit board 7 in a completely fixed state. When mounting the fixture 10, the tapered portion of the claw piece 10f comes into contact with the printed circuit board 7, causing the arm 10b to bend, and when the mounting is completed, the claw piece 10f is located under the printed circuit board. Then, the printed circuit board 7 is held between the claw pieces 10f, 10f and the protruding piece 10c to regulate the height position, and the contact piece 10g and the base body 10a regulate the position of the printed circuit board in the direction in which it comes off (in the direction of the arrow).

解除すればよい。 The engagement of fixture 10 with fixture boss 6 is best shown in the cross-sectional view of FIG. The claw piece 10d provided at the tip of the folded piece 10e engages with the protrusion 6c to prevent it from coming off. The tip of the claw piece 10d is inserted into a notch in the base portion 6a. Fixture base 10
The height of the fixture is determined by the contact between the top surface portion of a and the convex portion 6b of the fixture boss. When removing the fixing tool 10 from the illustrated engaged state, use the folding piece 10e.
The engagement between the claw piece 10d and the protrusion 6c can be released by holding the protrusion 6c with a finger.

する溝部を形成できる部分であれば良い。 In the above embodiment, a pair of board bosses and one fixture boss are used, but the number may be changed depending on the size of the printed circuit board to be fixed. Further, the fixing tool boss does not have to have the same shape as the substrate boss, and only needs to be provided with means for engaging with the fixing tool. Furthermore, the side wall of the chassis may be any other part of the chassis that can form a groove into which the end of the printed circuit board fits.
