Conventionally, the support brackets used for vibration isolation and sound insulation have been configured as described above, and thus have the following problems.
That is, in the case of the configuration disclosed in Patent Document 1 described above (FIG. 12), since the connection piece 13 has a surface orthogonal to the axial direction of the first tube portion 11, for example, connection of a sound absorbing material or the like When connecting to a member, the surface directions are different from each other by 90 degrees, and a twist member for aligning the 90 degrees is required, and a large number of support fittings are used. Therefore, it is extremely difficult to improve the work efficiency of the attachment. It was.
Further, the support member 22 has to be connected to the angle 5, and the structure is complicated and it is difficult to reduce the cost.
Further, since the angle 5 is in direct contact with the cylindrical rubber 20, when another member is connected to the angle 5 by welding, heat is transmitted to the cylindrical rubber 20 through the angle 5, and the cylindrical rubber It was difficult to avoid 20 degradation.
Moreover, in the case of the structure of the above-mentioned patent document 2, since the angle of the member on the side to be connected to the nut of the rod member of the main body is connected by welding, when using a large number of vibration isolation structures, the mounting thereof The work required a lot of effort.

An anti-vibration support metal fitting according to the present invention includes a cylindrical body having an overall shape, and a first mounting member provided on an outer peripheral surface of the cylindrical body, the plate surface of which is formed along the axial direction of the cylindrical body. A partition wall integrally formed on the inner wall of the cylindrical body and having a surface orthogonal to the axial direction of the cylindrical body; a through-hole formed at an axial center of the partition wall; and the partition wall formed in the cylindrical body. First and second cylindrical rubbers provided in the first and second chambers, and a hole disposed on the first end surface of the first cylindrical rubber via a plate-like heat-resistant member , on the surface thereof A first fixing plate for connecting a second mounting member as a body edge having an L shape or a U shape by welding, and a second plate having a hole disposed on the second end surface of the second cylindrical rubber . a fixing plate, the first fixing plate hole, the plate-like heat-resistant member, the first cylindrical rubber of the center hole, the through hole, the second cylindrical rubber center Ana及 beauty of the second fixing plate A fixing bolt provided through the, and the second nut screwed on the tip portion of the fixing bolt that is exposed to the outside of the fixing plate consists, first ends of the cylinder, the The cylindrical rubber , the plate-like heat-resistant member, the first fixing plate and the second fixing plate are not in contact with the two end surfaces, and the base of the fixing bolt is below the surface within the hole of the first fixing plate. A gap is formed between the outer peripheral surface of each cylindrical rubber and the inner wall of the cylindrical body, and vibrations between the fixed plates are absorbed by the pair of cylindrical rubbers interposed between the fixed plates. It is the structure which was made to do.

Since the vibration-proof support metal fitting according to the present invention is configured as described above, the following effects can be obtained.
That is, since the plate surface of the first mounting member provided on the cylinder is formed along the axial direction of the cylinder, it is the same as the surface direction of the connection member such as the sound absorbing material, and the connection work of the sound absorbing material, etc. Becomes easy. In addition, since a fixed plate is provided on one end of the cylindrical rubber through a plate-like heat-resistant member among the pair of cylindrical rubbers, an L-shape or a U-shape as a trunk edge is provided on the fixed plate. Even when the mounting member is welded, heat during welding is suppressed to the cylindrical rubber side as much as possible, and deformation of the cylindrical rubber is suppressed. Further, since an L-shaped or U-shaped mounting member can be easily attached to the fixed plate, a member such as an angular wave color exterior plate made of a different material from the sound absorbing material is parallel to or perpendicular to the sound absorbing material. Can be installed arbitrarily.
In addition, since the cylindrical rubber is not in contact with the end face of the cylindrical body, it is possible to prevent deformation or damage of the cylindrical rubber during vibration absorption.

  The present invention includes a first mounting member provided with a plate surface along the axial direction on a cylindrical body, and a second mounting member welded to a first fixing plate provided on a cylindrical rubber via a plate-like heat-resistant member. An object of the present invention is to provide an anti-vibration support metal fitting which can be used for easy anti-vibration connection of different members.
