Next, the operation of the damper 10 will be described with reference to FIG. In this device, a damper 10 is provided at the tip of a fixed iron core 13 from which a pair of movable members 11 and 12 are sucked or released, and FIG. It is in a state of being held by suction, and when a coil outside the figure is energized here, as shown in FIG.
The other movable member 12 collides with and presses the first chamber 2a of the damper 10, and the fluid 4 in the first chamber 2a moves to the second chamber 3a through the through hole 1a. Then, the moving speed of the pair of movable members 11 and 12 is reduced due to the resistance generated when the viscous fluid 4 moves, and the other movable member 12 collides with the fixed iron core 13 as shown in FIG. The shock when doing is reduced. Also,
When the coil is energized in the opposite direction, the coil operates in the opposite manner to return to the state shown in FIG. 9A, but also at this time, the moving speed of one movable member 11 is reduced by the damper 10 and the impact is reduced.

In the damper 10, as described above, the impact when the pair of movable members 11, 12 collide with the fixed iron core 13 is reduced, and the collision noise generated at that time can be reduced. Since the fluid 4 is hermetically sealed by the sheets 2 and 3, the structure is simple and the external dimensions are small without the need for a sealing material as in the conventional example.
Moreover, since the chambers 2a and 3a are formed so as to have no reduced cross-sectional area toward the substrate 1, the sheets 2 and 3 can be formed into a hemispherical dome shape and can be easily formed.

Next, a sixth embodiment will be described with reference to FIG. The substrate 1 is made of a resin material such as a polyamide resin, and has a partition wall 1b having a through hole 1a formed in the center.
And an outer peripheral wall 1c erected on both sides of the partition wall 1b to form a substantially H-shaped cross section. The sheets 2 and 3 are made of, for example, fluoro rubber having a thickness of about 100 μm and have a flat shape, and are sandwiched by a holding member 5 similar to that of the fourth embodiment so as to cover the outer peripheral wall 1c of the substrate 1 in a state where the viscous fluid 4 is injected. Thus, the first and second chambers 2a and 3a are formed by sandwiching the peripheral edges 2b and 3b between the outer peripheral wall 1c of the substrate 1 and hermetically joining them by ultrasonic welding or the like.

In such a damper 10, the seats 2, 3
Has a flat shape made of fluoro rubber, so that the strength is constant due to the uniform thickness, and the sheets 2 and 3 are movable members.
When pressed by 11, it is elastically deformed from a flat state, so that wrinkles do not occur and the buffering action is stable, so that the mechanical life is also prolonged. Further, unlike the above-described first to fifth embodiments, Thus, the step of forming the sheets 2 and 3 into a dome shape or the like can be omitted.

According to the first aspect of the present invention, when a movable member constituting a relay or the like presses one of the chambers, the fluid moves to the other chamber through the through hole of the substrate, and the resistance at the time of the movement causes the fluid to move. The collision speed and impact force of the movable member are alleviated and the collision noise can be reduced, and the fluid is hermetically sealed with a sheet, so the structure is simple without the need for a sealing material and the external dimensions are small. In addition, since the chamber is formed so as not to have a reduced cross-sectional area toward the substrate, the sheet can be drawn into a dome shape, and the chamber can be easily formed.

According to the second aspect of the present invention, since the chamber is formed by stacking a plurality of sheets so that the cross-sectional area gradually increases toward the substrate, one of the chambers is pressed by the movable member. When it is done, one of the chambers is compressed in such a way that the sheets of a plurality of steps are folded in order at the steps, so that wrinkles do not occur, the buffering action is stable, and the mechanical life by repetition is extended. .

According to a fourth aspect of the present invention, a material which is difficult to be directly bonded to a sheet formed of rubber is used for the substrate, or a fluid to be filled in the chamber is between the sheet and the substrate. Even in the case where it is difficult to bond the sheet between them, it is possible to hold the peripheral portion of the sheet between the substrate with the holding member, and easily perform air-tight joining by ultrasonic welding, caulking, or the like.
