Next, a method of manufacturing this product will be described with reference to FIG. The substrate 1 shown in FIG. 2 is provided with an attachment portion 1f that is fitted and attached to a base that constitutes a relay or the like. First, as shown in Fig. 1 (a), an appropriate amount of fluid is applied to the sheets 2 and 3 that are formed in the dome shape in advance.
Inject 4 using a dispenser. Next, the same figure
As shown in (b), the first chamber 2b and the second chamber 3b are formed with the sheets 2 and 3 on both surfaces of the substrate 1 so as to cover both ends of the through hole 1a. Next, as will be described in more detail later, as shown in FIG. 2C, the sandwiching portions 1b and 1c of the substrate 1 are sandwiched between the peripheral edge portion 2a of the sheet 2 and the substrate 1 in which the through holes 1a are previously formed. Department
1d and 1e are ultrasonically welded to the peripheral edge portion 3a of the sheet 3 to be in close contact with each other, and the sheet 2 and the sheet 3 are joined to the substrate 1.
In this state, the first chamber 2b and the second chamber 3b are filled with air together with the fluid 4. Next, if this air is left under a reduced pressure in a sealed state, it will be degassed through silicon rubber with a high gas permeability, and as shown in Fig. 6 (d), the fluid
4 is hermetically sealed. At this time, since the fluid 4 made of fluorine oil or the like has a relatively high boiling point, it hardly penetrates the silicone rubber and leaks to the outside. The damper 10 manufactured in this manner is attached to a device such as the relay 20 as shown in FIG. After being attached to the apparatus, as shown in FIG. 5, at the stationary position of the movable frame 11d, the first chamber 2b or the second chamber 3b is always pressed, so that the damper 10 1 room 2b or 2nd room
Air does not enter the inside of 3b.

Next, a relay 20 using the damper 10 will be briefly described with reference to FIG. This relay 20
Includes a damper 10, an electromagnet device 11, pressing portions 12a and 12b, and a contact portion 13. Specifically, the electromagnet device 11
Includes a coil bobbin 11a, a coil 11b, a fixed iron core (not shown), a yoke 11c, an armature (not shown), a permanent magnet (not shown), and a movable frame 11d. Has been done. The coil bobbin 11a has a coil 11b
Is wound, the fixed iron core penetrates the winding body of the coil bobbin 11a, and one end of the protruding iron serves as a magnetic pole surface. The yoke 11c has one end serving as a magnetic pole surface facing the magnetic pole surface of the fixed iron core, and the other end coupled to the other end of the fixed iron core. The armature is located between the fixed iron core and the magnetic pole surface of the yoke 11c, and is attracted and separated from the magnetic pole surface by controlling the excitation of the coil 11b. Since the movable frame 11d is rotatably arranged on the yoke 11c while holding the armature and the permanent magnet, the movable frame 11d responds to the operation of the armature, and the pressing portions 12a and 12b provided on the movable frame 11d are integrated. The pressing action is performed.

Next, the operation of the damper 10 will be described with reference to an example shown in FIG. In the same figure (a), one pressing part 12a is in contact with one first chamber 2b of the damper, and when the coil 11b is energized, the other pressing part 12a is pressed, as shown in (b). The portion 12b collides against the other second chamber 3b of the damper 10 and presses it, and as shown in FIG. 2 (c), the fluid 4 in the second chamber 3b passes through the through hole 1a and reaches the one first chamber 2b. Moving. Then, the moving speed of the pressing portions 12a, 12b is reduced by the resistance generated when the viscous fluid 4 moves,
The impact when the armature collides with the fixed iron core or the magnetic pole surface of the yoke 11c is mitigated. Also, when the coil 11b is energized in the opposite direction, it operates in the reverse order to the state shown in Fig. 2 (d) and then returns to the state in Fig. 1 (a) .At this time, the damper 10 also fixes the armature. The impact when colliding with the iron core or the magnetic pole surface of the yoke 11c is mitigated.

In such a damper 10, since silicone rubber has high gas permeability, a sheet is formed on both sides of the substrate 1.
When the sheets 2 and 3 are closely attached to each other to form the first chamber 2b and the second chamber 3b, and the sheets 2 and 3 in which the fluid 4 is injected are left under reduced pressure, the inside of the sheets 2 and 3 is Since the air existing in the sheet is degassed through the silicone rubber, after injecting more than the predetermined amount of the fluid 4 as in the conventional example, the sheet 2,
There is no need to go through the complicated process of deforming 3 and expelling fluid 4 together with air, and it is no longer necessary to wipe off expelled fluid 4, which saves time and effort for production.
