いることになる。 Next, the opening/closing operation of the opening/closing lid 2 will be explained. FIG. 4 shows the lid closed state, where the contact portion 12e contacts the back surface of the front panel 8, the arm portion 12c is elastically deformed, and the pressing portion 12a presses the starting end of the cam portion 6. This pressing force is applied to the pressing portion 12a using the support shafts 12b, 12b as fulcrums due to the elastic deformation of the arm portion 12c.
Elastic force that tends to rotate itself counterclockwise F 1
This is due to. When the contact point between the cam portion 6 and the pressing force 12a is h, and the pressing angle of the pressing portion 12a at the point h is α, the pressing force F 2 becomes F 2 =F 1 ×cosα.
This pressing force F 2 is a force that tries to rotate the opening/closing lid 2 counterclockwise, and therefore, the opening/closing lid 2 is
M 1 = F 2 × R (R: Line of action direction of pressing force F 2 and support shaft 1
This means that a rotational moment (distance to 0) is acting.

ンパー機能として働くことになる。 As shown in Fig. 5, this rotational moment M 1 is applied when the lid is closed to the position where the pressing angle α = 0°, and from then on, the lid 2 is automatically closed. become. When the opening/closing lid 2 is opened clockwise from the position shown in FIG.
Since the pressing angle α=0° is maintained, the pressing force F 3 becomes the elastic force F 1 itself, but the rotational moment M 1 does not act on the opening/closing lid 2, and the sliding friction between the cam part 6 and the fixer 12 If the coefficient is μ, then f=μ×
A frictional force called F 3 acts to apply an appropriate brake to the opening/closing operation of the opening/closing lid 2. In other words, it functions as a damper.

b and 12b are engaged, and the opening/closing lid 2 is restricted from rotating at a certain opening angle.
(ト) 考案の効果
上述の如く本考案によれば、ロツク機構を為す
フイクサーをフロントパネルに取外し自在に装着
したので、疲労による変形が生じ、所望の弾性力

ても機能するので、開閉蓋の急激な開閉による損
傷も防止でき実用的価値が高い。(g) Effects of the invention As described above, according to the invention, the fixer that forms the locking mechanism is removably attached to the front panel, so even if deformation occurs due to fatigue and the desired elastic force cannot be obtained, It is easy to replace, and since the fixer also functions as a damper during the lid opening operation, damage caused by sudden opening and closing of the opening/closing lid can be prevented, which has high practical value.
