DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a substrate, which is formed of a resin material such as polyamide resin and has a through hole 1a at the center and is formed in a rectangular flat plate shape.

Reference numerals 2 and 3 denote sheets, for example, made of a polyamide resin having a thickness of 40 μm, and cover both ends of the through-hole 1a.
The peripheral edges are hermetically joined by ultrasonic welding or the like so as to form a first chamber 2a and a second chamber 3a by filling an appropriate amount of the viscous fluid 4 on both surfaces of the first chamber 2a. At this time, the chambers 2a and 3a are formed in a dome shape by stacking the sheets 2 and 3 in two stages so that the cross-sectional area increases stepwise toward the substrate 1.

Reference numeral 5 denotes a pressing member which is formed of a molding material such as a polyamide resin into substantially U-shape by opposing pressing portions 5a and 5b and a connecting portion 5c connecting the pressing portions 5a and 5b. The surfaces 5c and 5d are tapered so as to be inclined with respect to the connecting portion 5c so that the distance between the surfaces 5c and 5d becomes wider as approaching the opening direction of the U-shaped tip.

Numeral 6 denotes a movable member, which is formed in a substantially U-shape with opposing pieces 6a, 6a and a connecting portion for connecting the opposing pieces 6a, 6a with a molding material such as a polyamide resin.
The five connecting portions 5c are integrally formed and connected. And
The movable member 6 is driven by an electromagnet 61 of an electromagnetic relay shown in FIG. 4 so that a pressing member integrally connected around a movable shaft 6b that rotatably supports both ends of the opposing pieces 6a, 6a. Rotates with 5.

The operation of this device is as follows.
The movable member 6 is driven by the
When the pressing member 5 collides with one of the first chamber 2a and the second chamber 3a and presses that chamber, the viscous fluid 4 moves to the other chamber through the through hole 1a. The moving speed of the viscous fluid 4 is reduced by the resistance generated at that time, and the moving speed of the movable member 6 is reduced, so that the collision noise is reduced.

In such a damper, as described above, the moving speed of the movable member 6 of the electromagnetic relay is slowed and the collision sound is buffered, so that the collision sound and vibration of household electric appliances and automobiles are minimized. The pressing surfaces 5c and 5d of the pressing member 5 that rotates around the movable shaft 6b are suitable for use in a desired operation. For example, in the case of the pressing surface 5c, as shown in FIG. When the first chamber 2a is pressed to the pressing end where compression deformation occurs most, the sheet 2 becomes substantially parallel to the surface of the substrate 1, so that a shear force parallel to the surface of the substrate 1 is hardly applied to the sheet 2, and FIG. As shown in (1), extension and buckling hardly occur in the portion where the sheets 2 are stacked in two steps, so that the life of the damper can be prolonged and the damping force can be stabilized.
