ている。(B) Conventional technology As a conventional technology in which the lid mechanism is equipped with a damper mechanism,
For example, as disclosed in Japanese Utility Model Laid-Open No. 63-193888 (H05K 5/03), a damper gear is engaged with a gear provided on the lid, and at least one gear is engaged with the lid in a closed position. The position is shifted so that the meshing amount from the position to the lid opening completion position is gradually increased, and a damper action is added to the opening and closing of the lid.

When the lid is slidably in contact with the sliding portion and the lid starts to open, the first bending point of the S-shaped elastic body serves as the fulcrum of the elastic moment, and a weak braking force is applied to the lid.
As the lid body is further opened and the protrusion approaches the first fulcrum, the fulcrum of the elastic moment is the second of the S-shaped elastic body.
When the lid is opened, a larger amount of braking is applied from the middle of opening the lid to the completion of opening.

記蓋体（１）の突起（３）に対向する。In the figure, (1) has a protrusion (3) on a bearing portion (2) and is rotatable about a shaft (5) attached to a base body (4) such as a front panel or a housing as a spindle. Body, ( 6 ) is S
The elastic body ( 6 ) is a character-shaped elastic body, and the elastic body ( 6 ) is connected to the elastic holding portion (6b) via the arcuate slidable portion (6a) having one free end and the first bending point (7). Support part (6c) via bending point (8)
And the mounting portion (6d) are integrally formed by resin molding. The elastic body ( 6 ) is fixed to the base body (4) with a screw (not shown) or an adhesive agent, and the sliding portion (6a) is attached to the protrusion (3) of the lid body (1). opposite.

る。When the lid body (1) is closed, the protrusion (3) is separated from the sliding portion (6a) of the elastic body ( 6 ) as shown in FIG. 2 (a), and the lid body (1) is locked. Has been done. Next lid (1)
When the lid is opened, the projection (3) abuts and engages with the free end of the sliding portion (6a), and the lid (1) is slidably in contact with the sliding portion (6a), and the lid (1) is shown in FIG. 2 (a). Is rotated in the direction of arrow A. In this case, the fulcrum of the elastic moment of the sliding portion (6a) is at the S-shaped first bending point (7) of the elastic body ( 6 ), and a weak braking force is applied to the lid body (1). . As the lid body (1) goes beyond the opening position shown in FIG. 2 (b) and reaches the opening completion position shown in FIG. 3, the fulcrum of the elastic moment of the sliding part (6a) becomes the elastic body ( 6 ).
Since it moves to the S-shaped second bending point (8), a stronger braking force is applied to the lid body (1). That is, the lid (1)
When the lid is completely opened, the elastic moment of the elastic holding portion (6b) acts on the lid (1). In FIG. 2 (b), the sliding part (6a) is pressed in the direction of arrow B, but FIG. 2 (c)
In this state, the elastic holding portion (6b) is pressed in the direction of arrow C with the second bending point (8) as the fulcrum of the elastic moment.

初めは早く、蓋体（１）が開くに従って、徐々に遅くな
るように制動できる。The sliding part (6a) of the S-shaped elastic body ( 6 ) is longer than the elastic holding part (6b), that is, the distance from the fulcrum of the elastic moment to the point of action is long and the cross-sectional area is small. By doing so, it is possible to brake the opening speed of the lid body (1) so that it is fast at the beginning of opening the lid body (1) and gradually slows as the lid body (1) opens.
