## Abstract

A connector (1) that comprises first and second surfaces (20a) and (30a) disposed opposingly with an interval therebetween, said interval allowing the shielding body 100 to be inserted therein; a pressing member (4) having a through hole (40) and formed so as to be capable of extending and contracting by winding a prescribed wire material spirally around the through hole (40) as center such that a curvature thereof varies continuously around the through hole; and a holding part (31) that is inserted into a hole (103) formed in the shielding body and the through hole (40) and maintains a specific distance between the first and second surfaces (20a, 30a); wherein the pressing member (4a) and (4b) comprises: a first pressing member (4a) disposed between the first surface (20a) and the shielding body (100) such that a small-curvature side thereof in the extension and contraction direction faces the shielding body (100); and a second pressing member (4b) disposed between the second surface (30a) and the shielding body (100) such that a small-curvature side thereof in the extension and contraction direction faces the shielding body (100). Due to such a configuration, vibration from the vibrating body (10) is absorbed and transmission of the vibration to the shielding body (100) can be suppressed.

## Claims

### Claim 1

A connector provided in a connecting segment that connects a vibrating body that generates vibration and a plate-like shielding body that shields physical energy emitted from the vibrating body, which comprises:
first and second surfaces disposed opposingly with an interval therebetween, said interval allowing the shielding body to be inserted therein;
a pressing member having a through hole and formed so as to be capable of extending and contracting by winding a prescribed wire material spirally around the through hole as center such that a curvature thereof varies continuously around the through hole; and
a holding part that is inserted into a hole formed in the shielding body and the through hole and maintains a specific distance between the first and second surfaces; wherein
the pressing member comprises:
a first pressing member disposed between the first surface and the shielding body such that a small-curvature side thereof in the extension and contraction direction faces the shielding body; and
a second pressing member disposed between the second surface and the shielding body such that a small-curvature side thereof in the extension and contraction direction faces the shielding body.

### Claim 2 (depends on 1)

The connector according to claim 1, which comprises:
a first annular element and a second annular element disposed opposingly such that they clamp an inner peripheral part of the hole formed in the shielding body and respectively connect the small-curvature sides of the first pressing member and the second pressing member, wherein
the first and second annular elements are provided with a first restricting means that is engaged with the first pressing member and the second pressing member to restrict positional aberration of the first pressing member and the second pressing member in a radial direction, and a second restricting means that is engaged with the shielding body to restrict positional aberration of the shielding body in a surface direction.

### Claim 3 (depends on 1)

The connector according to claim 1, wherein the first and second surfaces have outer shapes smaller than a hole on the small-curvature side in the through hole and the hole formed in the shielding body.

### Claim 4 (depends on 1)

A shielding body attached to a vibrating body that generates vibration and shields prescribed physical energy emitted from the vibrating body, comprising a connector provided between a connecting segment that connects the vibrating body and the shielding body, and the connector is a connector according to claim 1.

### Claim 5 (depends on 2)

The connector according to claim 2, wherein the first and second surfaces have outer shapes smaller than a hole on the small-curvature side in the through hole and the hole formed in the shielding body.

### Claim 6 (depends on 2)

A shielding body attached to a vibrating body that generates vibration and shields prescribed physical energy emitted from the vibrating body, comprising a connector provided between a connecting segment that connects the vibrating body and the shielding body, and the connector is a connector according to claim 2.

### Claim 7 (depends on 3)

A shielding body attached to a vibrating body that generates vibration and shields prescribed physical energy emitted from the vibrating body, comprising a connector provided between a connecting segment that connects the vibrating body and the shielding body, and the connector is a connector according to claim 3.
