(1) Configuration of Device Main Body Although the device main body (circuit support plate 237 and radiator plate 216) 2 of the embodiment has a rectangular shape, it may have another shape such as a square shape. In addition, although the connecting plate 251 connects the ends on the short sides of the rectangular circuit support plate 237 and the heat sink 216, the ends on the long sides may be connected.

(2) Holding Body In the embodiment, one holding body 5 is provided for one instrument body 2. For example, the connecting plates 251 of two instrument bodies 2 are connected to each other by a second connecting plate. The holder 5 may be attached to the second connecting plate. Note that the number of instrument bodies 2 is not limited to two, and may be three or more. In addition, the device main body 2 is arranged side by side in the short side direction of the circuit support plate 237 and the heat sink 216, but it may be arranged side by side in the longitudinal direction, or three or more may be arranged side by side in the short side direction or the longitudinal direction. Alternatively, a plurality of them may be arranged in the lateral direction and the longitudinal direction.

(3) Openings In the embodiment, both the supporting member 6 and the fixing member 7 have the openings 61a and 71a for the anti-vibration means 8. However, if at least one of the supporting member and the fixing member has an opening, the size can be reduced. can be improved.
Although the openings 61a and 71a in the embodiment have a rectangular shape elongated in the direction (third direction) in which the central axis of rotation of the coil member 85 extends, they may have other shapes such as an ellipse and an oval. The opening is set to a size that does not interfere with the support member, the fixing member, and the coil member when an earthquake of a set magnitude occurs.
In the embodiment, ribs are not provided on the edges forming the openings 61a and 71a, but ribs may be provided.

(4) Supporting members In the embodiment, the supporting members 6 are provided at two locations on both ends of the instrument body 2 in the first direction. Support members may be provided, or support members may be provided at a plurality of locations in the first direction and the third direction, for example, at four locations in total, both ends in the first direction and both ends in the third direction. When three or more supporting members are provided, the fixing member has a plurality of installation-side main body portions and installation-side bent portions corresponding to the locations of the supporting members, and is connected via a plurality of vibration isolation means.

(5) Coil member In the coil member 85 of the embodiment, the wires are inserted through the through holes of the pair of coil support bodies 81 and 83. The wire may be attached directly to the supporting member or the fixing member by providing the bending portion 62 on the instrument side of the supporting member 6 or the bending portion 73 on the installation side of the fixing member 7 .

(6) First direction In the embodiment, when viewed from the front side, the tool body 2 has a rectangular shape, and the longitudinal direction of the rectangular shape is the first direction. There may be. Moreover, when the support supports the tool body in a plurality of directions, at least one direction may be the first direction.

(7) Positional Relationship Between Supporting Member and Fixing Member The installation-side main body portion 71 of the fixing member 7 of the embodiment is positioned inside in the first direction with respect to the instrument-side main body portion 61 of the supporting member 6 . However, for example, the instrument-side body portion of the support member may be located inside the installation-side body portion of the fixing member. In this case, the installation-side bent portion bends inward in the first direction, and the instrument-side bent portion bends outward in the first direction.

(8) Shapes of Tool-Side Main Body and Installation-Side Main Body The tool-side main body 61 and installation-side main body 71 of the embodiment form a straight line when viewed from the third direction. It may be curved. However, considering the strength, it is preferable that the shape viewed from the third direction is a straight line.

(9) Anti-Vibration Means In the anti-vibration means 8 of the embodiment, the coil supports 81 and 83 are arranged along the second direction. good. In this case, openings are provided in the installation side body portion and/or the instrument side body portion arranged parallel to the first direction, and the dimension in the second direction orthogonal to the first direction can be reduced.

(10) Ribs If there is a large difference in dimension between the instrument-side main body 61 and the installation-side main body 71 in the third direction, the instrument-side main body-side ribs and the installation-side main body-side ribs face each other in the first direction. You may stretch in the direction to do.
The instrument-side main body-side rib portion 64 and the installation-side main body-side rib portion 74 may extend in opposite directions in the first direction (this is an embodiment). In this case, even if the device-side body portion 61 and the installation-side body portion 71 have approximately the same size in the third direction, they will not interfere with each other in the third direction during an earthquake.
Although the instrument-side bending portion-side rib portion 65 and the installation-side bending portion-side rib portion 75 of the embodiment extend in opposite directions in the second direction, they may extend in opposite directions in the second direction.

(11) Supporting member In the embodiment, the connecting plate 251 of the instrument main body 2 and the supporting member 6 of the holder 5 are configured separately and connected. However, for example, the connection plate and the support member may be integrally configured.
The support member 6 has an instrument-side extension portion 63 that extends from an intermediate portion of the instrument-side body portion 61 in the third direction toward the instrument body 2 side. It may be extended to the side as it is to form a connecting portion with the instrument body.

(12) Main Body Side Ribs and Vibration Isolating Members As shown in FIG. Although extending more than the member 85, the coil member may protrude in the first direction from at least one of the instrument-side main body side rib portion and the installation-side main body side rib portion.

(13) Positional Relationship Between Main Body and Vibration Isolating Member In the vibration isolating member of the embodiment, when viewed from the third direction, the turning center axis of the coil member 85 is aligned with the instrument side main body 61 and the installation side main body 71. It is provided so as to be located in the center of the However, the turning center axis may be located between the instrument-side main body and the installation-side main body, and does not have to be positioned at the center.
