Abstract

A damper is disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member. The damper includes a cushioning member and a protecting member. The cushioning member is configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element. The cushioning member includes a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion. The protecting member is disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member.

First claim

What is claimed is:

1. A damper disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member, the damper comprising:
a cushioning member configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element, the cushioning member including a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion; and
a protecting member disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member, wherein
the cushioning member is formed by weaving metal wires such that a plurality of spaces are defined in the cushioning member, and
the protecting member is disposed in the plurality of spaces in the cushioning member.

2. The damper according to claim 1 , wherein
the protecting member is disposed to entirely cover the side surface portion.

3. The damper according to claim 1 , wherein
the protecting member is made of a viscous material.

4. The damper according to claim 1 , wherein
the protecting member has an annular shape made of a viscoelastic material.

5. The damper according to claim 1 , wherein
the cushioning member defines a through hole into which a portion of the supporting element is inserted.

6. The damper according to claim 1 , further comprising:
a first cover covering the opposite portion of the cushioning member;
a second cover covering the facing portion of the cushioning member; and
an adjusting member disposed between the first cover and a height reference portion and configured to adjust a distance between the first cover and the height reference portion.

7. An assembly comprising:
the damper and the supported member according to claim 6 ; and
a conductive connecting member connecting the damper to the supported member, wherein
the second cover of the damper has a conductivity,
a conductive mounting pattern is mounted on a surface of the supported member, and
the conductive connecting member connects the second cover of the damper to the conductive mounting pattern of the supported member, so that the damper is mounted on the surface of the supported member.

8. An electronic controller comprising:
the damper, the supported member, the supporting member, and the supporting element according to claim 1 , wherein
the supported member is a circuit board in which an electronic component and a conductive wiring are provided at an insulating substrate that has an electric insulation property, and
the damper is disposed in at least one of a space between the circuit board and the supporting element or a space between the circuit board and the supporting member, and
the circuit board is supported by the supporting member.
