左方への移動を規制される。 1 to 3 show a front view, a right side view, and a plan view of the fastener of this embodiment, and FIG. 4 shows an exploded perspective view of this embodiment. The fastener of this embodiment is integrally molded from a synthetic resin such as a diyuracon, and the first rotation regulating rib 1 and the second rotation regulating rib 2 extend perpendicularly to each other and have free ends facing each other. The ribs 1 and 2 are supported by a connecting body 3. The connecting body 3 has an arcuate curved surface 3a between the bases of the ribs 1 and 2. Bulging portions 3b, 3b are formed on both sides of this arcuate curved surface 3a. Note that the bulges 3b, 3b are not formed near the base of the first rotation regulating rib 1. A mounting portion 4 is formed below the connecting body 3, and a fixing screw insertion hole 4a is formed in the mounting portion.
A trapezoidal notch 5a is formed on one side of the printed circuit board 5 supported by the fastener having the above-mentioned configuration, and the width is narrower on the opening side. The width of the opening of this notch 5a is slightly larger than the width of both the ribs 1 and 2.
Therefore, when the printed circuit board 5 is inserted perpendicularly through the opening of the fastener as shown by the dashed line in FIG. 1, the notch 5a enters the fastener. If the other side of the printed circuit board 5 is fixed in this state, the printed circuit board 5 can be installed without any looseness. That is, the printed circuit board 5 is restricted from moving to the right in FIG. 1 by the plate surface of the first rotation regulating rib 1, and is restricted from moving to the right in FIG. Movement to the left in the figure is restricted.

When the other side is unfixed and the printed circuit board 5 is rotated around the fasteners, the notch 5a engages with the bulged portions 3b at the apex and is retained by the arcuate curved surface 3a. , the bottom surface of the notch 5a slides. When the printed circuit board 5a rotates to a horizontal state, it is rotated by the free end of the first rotation regulating rib 1 and the plate surface of the second rotation regulating rib 2, as shown by the dots in FIG. Rotation is restricted, and the printed circuit board 5 is horizontally supported while being prevented from coming off.
