形成されている。2. Description of the Related Art Conventionally, as this kind of damper, there is a damper disclosed in Japanese Patent Application No. 5-105273 filed earlier, which has a through hole 1a as shown in FIGS.
And a substrate covering both ends of the through hole 1a.
1 and sheets 2 and 3 respectively forming a first chamber 2a and a second chamber 3a on both sides of the substrate 1;
Fluid hermetically sealed so that it can move through the other chamber
The chambers 2a and 3a are formed by stacking sheets 2 and 3 in two stages so that the cross-sectional area increases stepwise toward the substrate 1.

その一方の室は２段のシートが段部の境界にて順に折り

る。The conventional damper described above is small and inexpensive, and when one of the chambers is pressed by the movable member 5 as shown in FIG.
One of the chambers is compressed in such a manner that the two sheets are sequentially folded at the boundary of the step, so that wrinkles do not occur, the buffering action is stable, and the mechanical life by repetition is extended.

(c) の変位S2で停止する。[0004] However, when the sheet is folded at the step, the load applied to the movable member 5 has a maximum value. That is to say, referring to FIGS. 7 and 8, the small diameter portion of the sheet 2 forming the first chamber 2a is changed by the displacement S from the state of FIG. 7A where the movable member 5 does not press the first chamber 2a. When the pressing is performed, the load F applied to the movable member 5 is inverted and folded so that the small-diameter portion enters the large-diameter portion with the step portion 2b as a boundary and approaches the direction of the substrate, as shown in FIG. reversing load Fa is generated with the maximum value in the middle, over the local maximum value at the displacement S 1 shown in FIG. 7 (b) for the fluid
FIG. 7 in which 4 has moved to the second chamber 3a through the through-hole 1a.
stopping the displacement S 2 of (c).

寿命を短くする要因にもなる。Therefore, when this damper is used for a relay, for example, if the attraction force of the electromagnet is smaller than the above-mentioned reversing load Fa, the movable member 5 may stop working halfway or the like, or the reversing load Fa may be reduced. Each time the vehicle gets over, the stress applied to the steps of both seats 2 and 3 increases, which also shortens the mechanical life.

れてなる構成にしてある。In order to solve the above-mentioned problems, a damper according to the present invention comprises a substrate having a through hole formed therein and chambers formed on both sides of the substrate so as to cover both ends of the through hole. A sheet, and a fluid hermetically sealed so as to be able to move to the other chamber through the through hole of the substrate when one chamber is pressed, wherein the chamber has a stepwise sectional area toward the substrate. In a damper formed by stacking sheets in a plurality of stages so as to increase in order, the chamber is provided with a folded portion that once approaches the direction of the substrate at a boundary of a step portion of the sheet.

折り返し部21,31 が形成されている。The sheets 2 and 3 are made of, for example, a polyamide resin having a thickness of 40 μm.
The peripheral portions are hermetically joined by ultrasonic welding or the like so as to form a first chamber 2a and a second chamber 3a by sealing an appropriate amount of the viscous fluid 4 on both surfaces. At this time, the two chambers 2a and 3a are formed in a hemispherical dome shape by stacking the sheets 2 and 3 on the large diameter part and the small diameter part in two steps so that the cross-sectional area gradually increases toward the substrate 1. Have been. And that sheet 2,
At the boundary between the third step portions 2b and 3b, folded portions 21 and 31 that approach the direction of the substrate 1 once are formed.
【００１２】次に、このダンパーをリレーに使用した場

押圧される状態を図３及び図４で説明する。Next, when this damper is used for a relay, a state where the chamber is pressed by a movable member 5 driven by an electromagnet of the relay will be described with reference to FIGS. 3 and 4. FIG.

合も同様である。When the small diameter portion of the sheet 2 forming the first chamber 2a is pressed by the displacement S from the state of FIG. 3A where the movable member 5 does not press the first chamber 2a, the viscous fluid 4 is The speed of the movable member 5 is reduced by the resistance when moving to the second chamber 3a through the through hole 1a of the substrate 1 to reduce the sound of collision with the fixed member and the like, and the load F applied to the movable member 5 is reduced. When the small-diameter portion of the sheet 2 is folded into the large-diameter portion with the stepped portion 2b as a boundary, a folded portion 21 that once approaches the direction of the substrate 1 is already provided at the boundary. As shown by the solid line in FIG. 4, the fluid 4 penetrates through the intermediate displacement S 1 shown in FIG. Hole 1a
Until it stops in the displacement S 2 of FIG. 3 which has finished moving into the second chamber 3a through (c), substantially proportionally changed with respect to the displacement S. Conversely, the same applies when the second chamber 3a is pressed from the state of FIG. 3 (c).

Since the load F applied to 5 smoothly changes in proportion to the displacement S and becomes sufficiently smaller than the attractive force of the electromagnet of the relay, malfunctions such as the movable member 5 stopping halfway may occur. In addition, the stress applied to the sheets 2 and 3 is reduced, and the mechanical life can be extended.

Since the folded portion is already provided, it is possible to operate stably without generating a reversal load for folding as in the conventional example.
