できるとともに、その緩衝力も安定したものになる。In the dampers of the second and third embodiments, as described above, both pressing surfaces 5c and 5d of the pressing member 5 are used.
When pressing the two chambers 2a, 3a, the substrate 1 or the pressing member 5 rotatably supported on the parallel shaft 1b or 5f parallel to the movable shaft 6b of the rotating movable member 6, the two pressing surfaces 5c, The angle between the substrate 1 and the pressing member 5 as in the first embodiment is adjusted by self-adjustment while rotating about the parallel axis 1b or 5f so that the pressing force of the 5d against both chambers 2a and 3a becomes uniform. Since the pressing surfaces 5c and 5d are always parallel to the surface of the substrate 1 during the pressing process without requiring positional accuracy, the sheets 2 and 3
No parallel shearing force is applied to the first surface, no elongation or buckling occurs, the life of the damper can be further extended as compared with the first embodiment, and the damping force becomes stable.

As well as being suitable for use, the movable member to which the pressing member is connected rotates, but the pressing surface of the pressing member that presses the chamber to the pressing final end at which the sheet is most compressed deformed is on the substrate surface. Since the sheet is almost parallel, it is difficult for the sheet to be subjected to shearing force parallel to the substrate surface, and it is difficult for the sheet to elongate or buckle. become.
In addition, the sheet may be stretched or buckled compared to the conventional one.
Because it is difficult, the pressing surface and the base
Resistance generated between the plate surface (the pressing surface and the substrate surface separate
Force acting in the direction) becomes smaller,
Large holding power to maintain the state

Therefore, it is possible to prevent malfunction of the relay.

By self-adjusting while rotating around a parallel axis so that the pressing force of the pressing surface against the chamber becomes uniform, the pressing surface is always parallel to the substrate surface during the pressing process. No shearing force parallel to the substrate surface is applied, no elongation or buckling occurs, and the life of the damper can be made longer than that of the first aspect, and the damping force becomes stable.
