Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention of the present application is to prevent the resonance of a member due to a motor or the like by being adhered to a member such as a dehumidifier of an air conditioner or a refrigerator, various pipes such as a water heater, or a member such as a device having a motor, which receives vibrations. The present invention relates to the improvement of the vibration damping member.

[0002]

[Prior art]

 For example, pipes of refrigerant equipment such as dehumidifiers of air conditioners and refrigerators and pipes of water heaters resonate due to vibration. For this reason, conventionally, an adhesive member made of butyl rubber or the like is wrapped around the outer circumference of the pipe to cover the outer circumference of the pipe, thereby functioning as a weight of the pipe to prevent resonance of the pipe or to function as a spacer. I am. As shown in FIG. 6 (A), the conventional adhesive member includes a main body a made of an adhesive material such as butyl rubber, and a thin film body b having flexibility and covering the outer periphery other than the lower surface of the main body a. It is composed of and and is generally formed as follows. First, as shown in FIG. 6 (B), the main body a is placed on the transfer member K such as a conveyor from the nozzle opening N1 of the nozzle N and is sent together with the transfer member K at a predetermined speed. It is continuously pushed upward and transferred to the rear side (X direction in the drawing). At that time, the release paper c adheres to the lower surface of the main body a due to the adhesiveness of the main body a. On the other hand, by feeding the elongated film body b to the rear side so as to be in contact with the upper surface of the main body a, the film body b is sequentially adhered to the upper surface of the main body a due to the adhesiveness of the main body a. Cover the upper surface of the main body a. As described above, a plate-shaped adhesive member in which the upper and lower surfaces of the main body a are covered with the film body b and the release paper c, respectively, is obtained. When used, the release paper c is peeled off by cutting the pipe H as a member to be attached to about the entire length of the pipe H and wrapped around the pipe H as shown in FIG. 7 (A). As a result, the entire surface is along the entire outer circumference of the pipe, and the lower surface can be adhered to the entire outer circumference of the pipe due to the adhesiveness of the main body a. However, when the adhesive member is wound around the outer circumference of the pipe, the adhesive member is deformed into a curved shape in which the radius of curvature gradually increases from the lower surface side to the upper surface side, and the upper surface side is pulled in the circumferential direction. The body b is in a state of being elastically stretched by receiving a tensile force in the circumferential direction. As a result, as shown in FIG. 7 (B), with the passage of time, the adhesive member adhered to the outer periphery of the pipe gradually returns from both ends d and d due to the elastic force of the film body b trying to return. There is a problem in that the pipe may come off from the outer periphery. On the other hand, in the case of the main body a mainly composed of an adhesive such as butyl rubber, the specific gravity is small, and it may be difficult to exert the effect as a weight. In this case, it is possible to increase the specific gravity of the entire adhesive member by mixing iron powder, etc., which has a larger specific gravity than the adhesive body, but in that case, the body a becomes hard and plastically deforms. At the same time, it becomes difficult and the adhesiveness of the main body a decreases. Therefore, when an adhesive member mixed with iron powder or the like is wound around the outer periphery of the pipe, in addition to the elastic elongation of the film body b, the elastic force of the main body itself to return to the plate shape causes a decrease in adhesiveness and adhesiveness. , It's even easier to peel off.

[0003]

[Problems to be solved by the device]

 The present invention has been proposed in view of the above circumstances, and can reliably adhere to a member to be attached such as a pipe, and also keeps the initial connection state without peeling off over time. It is an object of the present invention to provide a vibration damping member that can be manufactured.

Another object of the present invention is to provide a vibration damping member capable of preventing elastic expansion of a film body having a surface covered when mounted on a member to be mounted such as a pipe.

[0005]

[Means for Solving the Problems]

 The present invention solves the above problems by providing a vibration damping member having the following features. The first invention of the present application includes a plate-shaped main body 1 having a predetermined thickness, and a tape member 6 covering the lower surface 11 of the main body 1. The main body 1 is made of an easily deformable body such as rubber or plastic that is easily deformable, so that the main body 1 can be deformed along the attached member. Is provided with an adhesive surface 61 to which an adhesive is applied. The upper surface of the tape member 6 is bonded to the lower surface 11 of the main body 1 with an adhesive. The term “easily deformable” as used in the present invention means that the human body 1 moves the main body 1 in the circumferential direction of the outer peripheral surface of a pipe used for a refrigerant equipment device such as a dehumidifier of an air conditioner or a refrigerator, or a water heater. Deformability to the extent that it can be deformed along it.

In the second invention of the present application, the main body 1 according to the first invention of the present application includes a film body 2 that covers at least the upper surface 12 of the main body 1. The film body 2 is adhered to the upper surface 12 forming the curved outer peripheral surface in a state where the plate-shaped main body 1 having a predetermined thickness is curved with the lower surface 11 as the inner peripheral surface.

In the third invention of the present application, the main body 1 according to the first or second invention of the present application includes a high specific gravity substance having a specific gravity larger than that of the easily deformable body. The tape member 6 is a double-sided tape having a lower adhesive surface 61 on the lower surface and an upper adhesive surface 62 on the upper surface.

In the first invention of the present application configured as described above, the tape member 6 having the adhesive surface 61 on the lower surface of which the adhesive is applied is adhered to the lower surface 11 side of the main body 1 with the adhesive. And By doing so, for example, even when the main body 1 contains another substance, and the main body 1 has poor deformability and adhesive force or has no adhesive force, the tape member 6 can be used to attach a member such as a pipe. Can be surely adhered to. Further, since the main body 1 and the tape member 6 are also adhered to each other with an adhesive, it is possible to prevent the main body 1 and the tape member 6 from being separated from each other.

In the second invention of the present application, the plate body 1 having a predetermined thickness is curved with the lower surface 11 as the inner peripheral surface, and the film body 2 is formed on the upper surface 12 forming the curved outer peripheral surface. It is attached. By doing so, if the lower surface side of the main body 1 is adhered along the outer periphery of the pipe as the member to be attached, the upper surface side of the main body 1 will be extended from the lower surface side, but the film body 2 will be extended. Since the film body 2 is coordinated in a closed state, it is possible to prevent the film body 2 from elastically stretching, and it is possible to maintain the adhesive state to the pipe.

In the third invention of the present application, the main body 1 is made to have a large specific gravity by including a high specific gravity material having a specific gravity larger than that of the easily deformable body, for example, iron or lead powder. Accordingly, it can be made suitable as a weight of a member to be attached such as a pipe, and can be made suitable as a vibration damping member for preventing resonance. On the other hand, even if the easily deformable body has adhesiveness, the inclusion of the high specific gravity substance reduces the deformability and adhesiveness of the main body 1 itself, and as a result, the elastic elongation of the film body 2 is temporarily reduced. Even if it does not occur, there is a risk of peeling from the member to be attached such as pipe due to the return due to the elasticity of the main body 1 itself which tends to return to the plate shape and the decrease in adhesiveness, but the adhesive surface 61 of the tape member 6 Thus, the main body 1 is adhered to the member to be attached, so that the adhered state can be maintained regardless of the decrease in elasticity and adhesive force of the main body 1. On the other hand, by using the tape member 6 made of a double-sided tape, the tape member 6 can be bonded and disposed on the lower surface side of the main body 1.

[0011]

[Embodiment of the invention]

 An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view of a part of an embodiment of a vibration damping member of the present invention, and FIG. 2 is a vertical sectional view taken along the line II-II of FIG.

The vibration damping member of the present invention comprises a main body 1, a tape member 6 covering the lower surface 11 of the main body 1, and a release paper 3 covering the lower surface 61 of the tape member 6, and the whole is substantially the same. It has a flat shape.

The main body 1 is mainly composed of an easily deformable body having adhesiveness at room temperature and easily deformable, such as rubber or plastic, and a high specific gravity material having a specific gravity larger than that of the easily deformable body. Is included. In this way, the main body 1 is mainly composed of an easily deformable body having an easily deformable property, so that the damping member attachment surface of the adhered member to which the damping member is attached can be shaped according to the shape of the adhered member. For example, in the case of piping, it shall be possible to freely deform only by the force of the human hand along the circumferential direction of the outer peripheral surface of the piping, and to include a high specific gravity substance having a specific gravity larger than that of the easily deformable body. As a result, the specific gravity of the entire main body 1 is increased, and the main body 1 can effectively function as the weight of the attached member such as the pipe for preventing the vibration of the attached member such as the pipe. In the present embodiment, butyl rubber is the main body, and the powdery substance of iron having a larger specific gravity than butyl rubber is included in the main body so that the overall specific gravity is 3 or more and the main body 1 has a little adhesive force. I have to. It should be noted that the high specific gravity substance to be mixed with the easily deformable body is not limited to iron, and may be any substance having a specific gravity larger than that of the easily deformable body such as lead. Further, the mixing ratio of the high specific gravity substance is not particularly limited and can be appropriately changed. If butyl rubber containing a high specific gravity substance such as iron powder is mixed with another substance, for example, a foaming substance such as cork, it can function as a weight for a member to be attached such as a pipe, and at the same time use as a heat insulating material. Can be suitable for.

Further, in the main body 1 of the present embodiment, the outer periphery of the main body 1 other than the lower surface 11 is covered with the film body 2. This film body 2 is for blocking the main body 1 from the air to prevent early deterioration, and for preventing adhesion of dust and the like to the outer peripheral surface of the main body 1 due to adhesiveness and adhesion of other things. . The film body 2 is made of a flexible material that does not impair the deformability of the main body 1. Specifically, a thin synthetic resin film or the like is used. The polyethylene film is used as the film body 2 in the present embodiment.

In this embodiment, the tape member 6 has a lower adhesive surface 61 and an upper adhesive surface 62 to which an adhesive is applied, on each of the lower surface and the upper surface. The upper adhesive surface 62 serves to bond the tape member 6 to the main body 1, and the upper adhesive surface 62 is bonded to the lower surface 11 of the main body 1 so that the tape member 6 is attached to the main body 1. It is attached and covers the lower surface 11 of the body 1. On the other hand, the lower adhesive surface 61 serves to function as an adhesive surface for the entire damping member to the member to be attached such as the pipe, and the upper adhesive surface 62 adheres to the lower surface 11 of the main body 1 as described above. As a result, the lower adhesive surface 61 forms the lower surface of the entire vibration damping member, whereby the lower adhesive surface 61 of the tape member 6 forms the adhesive surface of the entire vibration damping member.

The release liner 3 covers the lower adhesive surface 61 of the tape member 6 adhered to the main body 1 so that the damping member is taped until it is adhered to a member to be attached such as a pipe. It is for protecting the lower adhesive surface 61 of the member 6, and the same one as is generally used can be used. Although the film body 2, the tape member 6, and the release paper 3 are actually thinner than the thickness of the main body 1, they are shown thick in the figure for convenience of explanation.

In this embodiment, the vibration damping member configured as described above is formed as follows. As shown in FIG. 3, the main body 1 is continuously discharged onto a transfer member 4 such as a conveyor at a temperature of 70 to 80 ° C. from a rectangular nozzle opening 51 formed at the tip of the nozzle 5. The tape member 6 is placed on the transfer member 4 with the same width as the width of the main body 1 discharged from the nozzle port 51, and the tape member 6 is sequentially and continuously rearwardly (X direction in the drawing) together with the transfer member 4. ) Has been sent to. In this tape member 6, the release paper 3 is previously adhered to the lower adhesive surface 61 on the lower surface side, and the adhered release paper 3 is placed on the lower side and the tape member 6 is placed on the transfer member 4 on the upper side. Has been done. Further, the transfer member 4 is provided with two front and rear horizontal portions 41, 42 and a curved portion 43 formed between the front and rear horizontal portions 41, 42. The curved portion 43 forms an arc surface having a radius similar to the radius of the pipe to which the vibration damping member is adhered, and the curved horizontal portion 42 positions the rear horizontal portion 42 below the front horizontal portion 41. Has been done. The curved portion 43 can be formed, for example, by disposing a wheel 44 having a radius approximately equal to the radius of the pipe and arranging the transfer member 4 along the wheel 44, but it may be performed by another method. It is possible and can be implemented with appropriate changes.

Then, the main body 1 discharged from the nozzle port 51 is sequentially placed on the upper adhesive surface 62 of the tape member 6 and sent to the rear side. At this time, when the main body 1 is made of only butyl rubber, for example, the main body 1 itself has an adhesive force, but as in the present embodiment, the butyl rubber contains iron powder as a high specific gravity substance. However, in the present embodiment, since the upper adhesive surface 62 is formed on the upper surface of the tape member 6 and the main body 1 is placed on the upper adhesive surface 62, The tape member 6 can be reliably bonded. When the main body 1 placed on the release paper 3 and the tape member 6 enters the curved portion 43 of the transfer member 4, the lower surface 11 side of the main body 1 adhered to the release paper 3 and the tape member 6 bends without expanding and contracting. Along the portion 43, the radius of the curved portion 43 (radius of the wheel 44) is deformed into a curved shape with a radius of curvature R1, while the upper surface 12 side of the main body 1 pulls in the circumferential direction of the curved portion 43 (P1 in the figure). -P1 direction) and is extended to be deformed into a curved shape with a radius of curvature R 2 from the center O of the wheel 44 to the upper surface 12, and the entire body 1 in the thickness direction has a curved portion 43. Deforms in a curved shape along.

On the other hand, on the upper side of the transfer member 4, a tape-shaped film body 2 having a width sufficient to cover the upper surface 12 and the left and right side surfaces of the main body 1 is provided along the transfer direction of the transfer member 4. The film body 2 is arranged so as to be capable of being transferred, and is configured to come into contact with the upper surface 12 of the main body 1 which is being transferred while being deformed into a curved shape at the curved portion 43 of the transfer member 4. Therefore, the film body 2 is brought into contact with the upper surface 12 of the main body 1 in the state of being stretched in the circumferential direction of the bending portion 43. Then, due to this contact, the film body 2 is curved and deformed into a curved shape, and the film body 2 is sequentially bonded and arranged on the upper surface 12 of the main body 1 by the adhesive force of the main body 1. At this time, if the main body 1 contains the iron powder as described above, the adhesive force is reduced, but the film body 2 after the main body 1 is adhered to the mounted member is the tape member 6. As described above, since the weight of the main body 1 is not applied after the main body 1 is adhered to the member to be attached, it is sufficient to simply adhere the main body 1 to the state that the main body 1 is covered, and the main body 1 is adhered by the adhesive force. obtain. However, an adhesive may be applied to the lower surface of the film body 2 so that they are adhered to each other by an adhesive, which can be appropriately changed.

After that, when the main body 1 is transferred on the transfer member 4 from the curved portion 43 to the rear horizontal portion 42, it is returned from the curved deformed state to the plate shape. When the main body 1 returns to the plate shape, the upper surface 12 side of the main body 1 that has been stretched in the circumferential direction of the bending portion 43 when passing through the bending portion 43 is returned to the original state as it enters the rear horizontal portion 42. The film body 2 adhered to the upper surface 12 of the main body 1 stretched in the circumferential direction of the curved portion 43 in the left and right direction is compressed by the compressive force (P2-P2 direction in the drawing) in order to shrink. 21 (see FIG. 1) extending in the longitudinal direction are arranged in parallel along the front-rear direction. Further, in the present embodiment, the wrinkles 21 ... 21 are longer than the length of the body 1 when the wrinkles 21 ... 21 are extended by peeling off the film body 2 from the body 1 having a predetermined length. It is formed to be about 35% longer.

Although not shown, in the rear horizontal portion 42 of the transfer member 4, both widthwise edges of the film body 2 adhered in a wrinkle shape to the upper surface 12 of the main body 1 are located on the side of the transfer member 2. It is bent downward by a roller or the like provided on the main body 1 and adhered to the left and right surfaces of the main body 1.

Then, by cooling to room temperature, a long vibration-damping member whose main body 1 is easily deformable is obtained. When the main body 1 is cooled to room temperature, the main body 1 undergoes some heat shrinkage, and the heat shrinkage causes some wrinkles. Therefore, the wrinkles 21 ... 21 of the film body 2 include wrinkles due to heat shrinkage. Be done. However, the amount of wrinkles due to thermal contraction is smaller than the amount of wrinkles due to the compressive force applied when entering the rear horizontal portion 42 from the curved portion 43.

Next, the use of this vibration damping member will be described with reference to the case where it is attached to the outer periphery of the pipe. First, the outer peripheral length of the pipe to be used is cut, the release paper 3 is peeled off, and the lower adhesive surface 61 of the tape member 6 is exposed. Then, as shown in FIGS. 4 (A) and 4 (B), the pipe H is wound around the outer circumference thereof. Thereby, the lower bonding surface 61 can be bonded to the entire outer peripheral surface of the pipe H. Further, at that time, when the lower adhesive surface 61 adheres along the entire circumference of the outer peripheral surface of the pipe, the upper surface 12 side of the vibration damping member is pulled in the circumferential direction and is just deformed by the curved portion 43 of the transfer member 4. The curved shape is almost the same as that of. As a result, the film body 2 on the upper surface 12 side becomes substantially in the same state as the wrinkles 21 ... 21 are stretched in the circumferential direction and adhered to the upper surface 12 of the main body 1 by the curved portion 43 of the transfer member 4 and elastically stretched. Will not occur. Further, the deformability and adhesive strength of the main body 1 are lowered because the main body 1 contains the iron powder, but since the lower adhesive surface 61 of the tape member 6 adheres to the pipe, It is possible to prevent the both ends of the vibration damping member from peeling from the pipe due to the return of the main body 1 itself due to the elasticity of the main body 1 itself, which tends to return to a plate shape, or the decrease in the adhesive force. Therefore, in the vibration damping member, the adhesive surface 61 adhered to the outer periphery of the pipe is elastically generated by elastic elongation of the film body 2 as in the past, or the deformability and the adhesive force are decreased as in the conventional case. 11a, 11a can be prevented from peeling off, and the adhesive state can be maintained. On the other hand, even between the main body 1 and the tape member 6, since the upper adhesive surface 62 of the tape member 6 adheres, even if the deformability and the adhesive force of the main body 1 are similarly reduced, It is possible to prevent the tape member 6 from coming off from the gap, and it is possible to reliably maintain the adhered state.

In the present embodiment, the curved shape of the upper surface 12 of the main body 1 when the film body 2 is bonded to the main body 1 is an arc surface having a radius similar to the radius of the pipe used. Not limited to this form, if the bonding is performed on an arc surface having a radius smaller than the radius of the pipe to be used, the wrinkles 21 of the film body 2 will remain even if they are bonded to the outer peripheral surface of the pipe. Therefore, it is possible to prevent elastic elongation. Further, even if elastic elongation occurs, there is no problem as long as the adhesive surface 11 of the main body 1 adhered to the outer periphery of the pipe does not separate from both ends 11a and 11a with the passage of time. Therefore, it is slightly larger than the radius of the pipe to be used. It may be an arcuate surface having a radius of a certain degree, and can be appropriately changed.

Further, in the present embodiment, the film body 2 covers the upper surface 12 and the left and right side surfaces of the main body 1, but the present invention is not limited to this form, and the upper surface may be, for example, as shown in FIG. 12 or only the upper surface 12 and the left or right side surface, and further covered with the film body 2 so as to cover the entire upper surface 12, the left and right side surfaces and the lower surface of the main body 1. The tape-shaped member 6 may be adhered to the lower surface, and may be changed as appropriate.

Further, in the present embodiment, the film body 2 which is about 35% longer than the length of the main body 1 is adhered to the upper surface of the main body 1 so that the wrinkles 2 of the film body 2 are formed on the upper surface of the plate-shaped main body 1. 1 ... 21 is formed, and it is particularly suitable when the vibration damping member mounting surface of the mounted member has a curved shape such as piping, but the length of the main body 1 is not limited to this form. If the wrinkles 21 ... 21 are formed by using the film body 2 that is 10% or more longer than that, peeling due to elastic elongation of the film body 2 when wound around the pipe H can be suppressed. Further, by forming the wrinkles 21 ... 21 on the film body 2 as described above, it is particularly suitable when the vibration damping member mounting surface of the mounted member has a curved shape such as piping. However, the film body 2 may be wrinkle-free by bonding the stretched film body 2 to the upper surface of the plate-shaped main body 1 as in the conventional case. In that case, when the damping member mounting surface is mounted on a mounted member having a flat surface, the film body 2 does not elastically expand. 1 is easily peeled off from the pipe. However, the tape-shaped member 6 can make it difficult to peel from the pipe.

Further, in the present embodiment, the main body 1 is made of an easily deformable body such as rubber or plastic which is easily deformable and has an adhesive property at room temperature, and is made of iron having a specific gravity larger than that of the easily deformable body. It is composed of a material having a little adhesive force by including a high specific gravity substance such as powder, but if it is easily deformable, the main body 1 itself does not have an adhesive force. It may be, for example, easily deformable and sticky at room temperature. An easily deformable body is made of a material having no adhesive force by incorporating a high specific gravity substance such as iron powder, or By including a high specific gravity substance such as iron powder in a material that is deformable and not tacky at room temperature, or from a single substance that is easily deformable and is not tacky at room temperature It may be configured and may be appropriately changed. Further, when the main body 1 is made of such a material that does not have an adhesive force to the main body 1 itself, there is no possibility that dust, dust, etc. will adhere to the main body 1, so that the main body 1 can be mounted as in the above embodiment. It is not necessary to cover with the film body 2, and the main body 1 and the tape member 6 can constitute the vibration damping member of the present invention and can be appropriately changed.

On the other hand, in the present embodiment, the tape member 6 having the lower adhesive surface 61 and the upper adhesive surface 62 to which an adhesive is applied in advance on both upper and lower surfaces is used, but the present invention is not limited to this embodiment. For example, when the tape member 6 is provided with the lower adhesive surface 61 only on the lower surface without providing the upper adhesive surface 62 on the upper surface, when the upper surface of the tape member 6 is adhered to the lower surface 11 of the main body 1, the upper surface of the tape member 6 is Alternatively, the lower surface 11 of the main body 1 may be adhered by interposing the adhesive between the lower surface 11 of the main body 1 and the upper surface of the tape member 6 by applying the same while coating the adhesive. , Can be changed as appropriate. Further, although the tape member 6 is arranged on the entire lower surface 11 of the main body 1 in the present embodiment, it may be arranged on a part of the lower surface 11 of the main body 1, for example, As shown in FIG. 5 (B), the tape member 6 is made narrower than the lateral width of the main body 1, and one or a plurality of tape members (in FIG. 5 (B), two tapes are arranged are shown. It may be arranged along the longitudinal direction of the main body 1, and may be appropriately changed. Further, as shown in FIG. 5 (B), when the tape member 6 having a width smaller than the width of the main body 1 is arranged, the release paper 3 covers the entire lower surface of the main body 1 from the lower side of the tape member 6, Alternatively, only the lower surface of the tape member 6 may be covered. For example, when the main body 1 itself has an adhesive force, the portion of the lower surface of the release paper 3 where the tape member 6 is not provided and the lower surface of the tape member 6 may be covered. If the main body 1 itself does not have an adhesive force, it is sufficient to cover only the lower surface of the tape member 6 and can be appropriately changed.

Further, the member using the vibration damping member of the present invention is a member that receives vibration of refrigerant facility equipment such as dehumidifiers of air conditioners and refrigerators, various pipes such as water heaters, or equipment having a motor. The vibration-damping member-mounting surface of the member to which the vibration-damping member is mounted can be mounted regardless of whether it is a curved portion or a planar portion, and can be appropriately modified and used.

[Effect of the invention]

 As described above, the first invention of the present application uses the tape member 6 even if the main body 1 contains another substance, and the main body 1 has a poor deformability and adhesive strength, or no adhesive strength at all. It is possible to surely adhere it to a member to be attached such as a pipe. Further, even between the main body 1 and the tape member 6, since they are adhered with an adhesive, it is possible to prevent the main body 1 and the tape member 6 from being separated from each other.

In the second invention of the present application, when the lower surface side of the main body 1 is adhered along, for example, the outer circumference of the pipe as the member to be attached, the upper surface side of the main body 1 is extended from the lower surface side. Since the film body 2 is coordinated in the stretched state, it is possible to prevent the film body 2 from elastically stretching and to maintain the adhesive state to the attached member such as the pipe. it can.

In the third invention of the present application, the main body 1 has a large specific gravity by including a high specific gravity substance having a specific gravity larger than that of the easily deformable body, for example, iron or lead powder. It can be made suitable as a weight of a member to be attached such as a pipe, and can be made suitable as a damping member for preventing resonance. On the other hand, by including the high specific gravity substance, even if the deformability and adhesiveness of the main body 1 itself are reduced, the main body 1 is attached to the pipe by the adhesive surface 61 of the tape member 6, so that the elasticity and the elasticity of the main body 1 are reduced. The adhered state can be maintained regardless of the decrease in adhesive strength. Therefore, it is possible to easily obtain a suitable vibration damping member having a high deformability and a large specific gravity. On the other hand, by using the tape member 6 made of a double-sided tape, the tape member 6 can be bonded and disposed on the lower surface side of the main body 1, which can be easily manufactured.
