Embodiment 1 FIG. FIG. 1 is a perspective view showing a state in which a plate spring fitting integrally formed with a fitting according to Embodiment 1 of the present invention and an attached body to which the leaf spring fitting is attached are separated. The attached body 3 in this case is a sheet metal or a metal plate on which electric components of an electric device such as a CRT are mounted, or a conductive plate component such as a board or a housing.

The leaf spring fitting 1 is used for achieving electrical conduction (grounding) to other conductive plate parts to obtain an effect of, for example, electromagnetic wave shielding, and is made of an elastic steel plate. The attachment 2 is integrally formed. The attachment 2 has two strips 5 and 5 formed on one side of a substantially rectangular plate 4, and a pair of protrusions projecting perpendicular to the plate surface of the plate 4. Engaging claws 6, 6 are provided.

The two band portions 5 and 5 are used to sandwich the to-be-clamped pieces 7 formed on one side of the plate portion of the attached body 3 from both front and back sides. The clamped piece 7 is formed by a pair of slits 12 and 1 extending inward from one end of the plate portion of the mounted body 3.
2 are formed. The two band portions 5 of the fixture 2 are parallel to one side of the plate 4, and the two band portions 5 are separated from each other by a slit 8 along the band portion 5.
Further, one band 5 is swollen to the surface side of the plate body 4 by drawing and slightly protruded, and the other band 5 is drawn.
Is drawn to the rear side of the plate body 4 and slightly protruded by drawing. In this drawing, the gap in the thickness direction between the two belt portions 5 is set to be equal to or less than the thickness of the clamped piece 7 of the attached body 3, whereby the sandwiched piece 7 is clamped by the two band portions 5. It can be attached securely.

The pair of engaging claws 6, 6 are engaged with a pair of engaging holes 9, 9 formed in a plate portion of the attached body 3, and are disposed in a longitudinal direction of the band portion 5.

The mounting can be performed so as not to occur, and the mounting reliability and the mounting stability are improved as compared with the conventional example.

Further, the two band portions 5, 5 of the mounting member 2 are bent and deformed, and the holding pieces 7 of the mounted body 3 are sandwiched between the two band portions 5, so that a pair of engagements of the mounting member 2 are performed. Claws 6 and 6 are attached to body 3
It is only necessary to engage with the engaged holes 9, 9, so that the mounting workability is greatly improved as compared with the conventional example.

Further, since the band portion 5 and the engaging claw 6 are formed integrally with the mounting plate 4, the mounting device 2 can be simply constructed without requiring an assembling process.

Embodiment 2 FIG. As shown in FIG. 5, the two engaging claws 6 of the mounting tool 2 are engaged with the engaged hole 9 and the force P is released, and the two engaging claws 6 are engaged with the engaged hole 9. An adjustment gap (play) G between which the band portion 5 can be flexed and deformed.
May be set so as to obtain. In this case, a force indicated by an arrow P in the same figure is applied again in the attached state to push the mounting plate 4 inward from both sides thereof, so that the both band portions 5 can be bent and deformed. The leaf spring 1 in the state can be easily removed from the attached body 3.

That is, by adjusting the size of the adjustment gap G, the degree of freedom of bending of the strips 5 and 5 provided on the fixture 2 after attachment can be adjusted, and the fixture 2 can be removed or not. Can be freely selected. Adjustment gap G
When the width is increased, it becomes easy to bend the band portions 5 and 5 again after installation, and the band portions 5 and 5 can be removed. Conversely, when the adjustment gap G is narrowed, it becomes difficult to bend the band portions 5 and 5, and it becomes impossible to remove the band portions 5 and 5. can do.
