Description

  The present invention relates to a vibration damping device for reducing vibration of a building structure caused by so-called daily noise, and particularly to reduce vibration by being attached to a face material support used for supporting a wall surface, a ceiling or the like. It is related with the vibration control device for.

  In ordinary houses, especially in densely built residential areas or apartment buildings, noise and vibration generated by people living in the neighborhood or in the next room or upper floor often become a problem, which can also cause neighborhood troubles. ing. These noises and vibrations are caused by sounds generated in daily life (so-called daily noises), but depending on lifestyle, there are a variety of sounds such as sounds generated from TV and musical instruments, conversational voices, and footsteps on the upper floors. It is caused by the cause of. These living noises are transmitted to the neighborhood or the adjacent rooms or lower floors by vibrations, which are unpleasant sounds. In addition, vibrations generated by opening / closing doors and walking on the upper floor are also transmitted to the adjacent rooms, lower floors, etc., which are unpleasant vibrations.

  Therefore, in a general building structure, an attempt has been made to solve the problem by using a shock absorbing structure for the wall surface and ceiling, or using a soundproof material. However, these are provided for interrupting the propagation of vibration (reducing the amplitude) in the vibration transmission system, and have not yet reduced the amplification effect due to the resonance phenomenon of sound and vibration. That is, a building (particularly a planar portion) has a unique frequency when vibrating due to its structure, and when it vibrates due to noise or the like, the amplitude increases as the frequency of the vibration approaches the unique frequency of the building. Become. For this reason, unless the propagation of vibration is sufficiently interrupted, vibration is amplified by a resonance phenomenon, so that it has not yet been solved enough for daily noise.

  Therefore, in order to reduce daily noise and vibration due to these resonance phenomena, a plurality of vibration damper weights (a rubber damper with a weight attached thereto, the same applies hereinafter) are attached to the vibration target member and transmitted. The vibration energy is absorbed by the weight to reduce the amplitude of daily noise and the like (see Patent Documents 1 and 2).

Japanese Patent Laid-Open No. 11-141600 JP 2006-77517 A

  However, since the technique disclosed in Patent Document 1 directly attaches a damper weight capable of vibration to a vibration target member (wall or ceiling), in order to obtain a sufficient damping effect, vibration is required. A plurality of damper weights had to be mounted for each target member, and the number of the members had to be enormous. Moreover, although the technique disclosed by the said patent document 2 mounts several damper weights in the field edge which supports a ceiling (vibration target object) and is not the direct mounting | wearing with respect to a vibration target object, a field edge It has been proposed that a plurality of damper weights be attached along the line to absorb the entire vibration of the vibrating object. However, in the configuration in which the damper weight is provided only at the field edge, it is not easy to sufficiently eliminate the vibration of the vibration object that is a vibration transmission source. That is, the field edge supports the object to be vibrated, and is a relatively strong structure in the building structure, and cannot sufficiently transmit the vibration propagated from the object to be oscillated. The vibrations eliminated by this were a slight amount of the entire vibration of the vibration object.

  Mounting a large number of weights in this way is expected to have a vibration-damping effect by providing a large number of weights that resist vibration, but the number of mountings increases, and installation is very laborious. In addition, it is not easy to equalize the vibration frequency of each individual weight, and if the vibration frequency is different, the damper weight that can actually function is limited, and a significant vibration reduction effect cannot be expected. There was a problem.

  The present invention has been made in view of the above-mentioned various points, and an object of the present invention is to provide a vibration damping device that can reduce vibration generated by so-called daily noise by a structure that can be easily mounted. .

  Therefore, the present invention is a vibration damping device for reducing vibration of a face material by attaching it to a face material support part that supports a face material used for a building structure, and is attached to the face material support part. Possible mounting means, a face material abutting portion supported directly or indirectly by the mounting means and capable of abutting on the face material, and directly or indirectly continuous with the face material abutting portion And an oscillating means that oscillates in response to transmission of vibration.

  According to the above configuration, the vibration damping device is attached to the face material support portion by the attachment means as a whole and does not need to be individually installed on the face material, but the face material contact portion contacts the face material, The vibration of the face material can be transmitted to the oscillation means. The oscillating means oscillates in response to vibrations transmitted from the face material abutting portion, and operates to cancel vibrations caused by daily noise. That is, the oscillating means resonates and vibrates in response to the transmission of the vibration of the face material, and the vibration energy of the face material decreases as it moves to the oscillating means, and vibration of the face material due to noise or the like. Is reduced.

  Here, the face material is a ceiling board (ceiling material or ceiling finishing material) in the case of a ceiling, and a wall board (wall surface material or wall finishing material, etc.) in the case of a wall surface, such as a plaster board Is used. In the case of a ceiling, the face material support part is a base frame such as a field edge, and in the case of a wall surface, it is a base frame such as a stud or a trunk edge. There is a case. Such base rails are arranged at appropriate intervals on the ceiling surface and the wall surface, and an appropriate number of vibration control devices can be attached to the individual base rails. In addition, the state in which the face material abutting portion is directly supported by the mounting means refers to the case where the face material abutting portion is joined to the mounting means and a part of the material constituting the mounting means is a surface. The case of functioning as a material abutting part is considered, and the indirectly supported state is a result of pressing at the time of mounting in addition to the case where a member having another function is interposed between the two The case where it is in the state where it was supported in general is included. In addition, the state in which the oscillation means is directly connected to the face material abutting portion means a case in which both are made of the same material and continuous in a state in which both perform their functions, The state of being indirectly continuous is not only when some material is interposed in the middle, but is composed of the same material, but something that performs other functions is interposed between them. Means the case.

  In the invention having the above-described configuration, as the oscillating means, while the mounting means is supported by the face material support part, the gap between the both sides of the face material support part is appropriately held while appropriately holding a gap from the face material. It can be set as the structure provided with the vibration member which protrudes in both sides, and the weight which can be attached or detached with respect to this vibration member.

  When the vibration member has an appropriate distance from the face material, it can vibrate away from the face material, and the vibration frequency during vibration can be adjusted by the weight. In addition, vibration energy is absorbed by the movement (amplification) of the weight and the vibration of the face material is reduced. The vibration energy absorbed can be adjusted according to the weight of the weight. It becomes. Therefore, by increasing the weight of the weight used for a single vibration damping device, it is possible to obtain a vibration reduction effect with a small number of vibration damping devices. The vibration member and the weight (oscillation means) can be provided so as to protrude only on one side, in addition to the case where the vibration member and the weight (oscillation means) are provided on both sides of the face material support portion. By providing the oscillating means on both of the face material support portions, when both vibration members cancel each other, the effect of absorbing the vibration of the face material is diminished. In such a case, the oscillating means may be provided only on one side.

  In the above configuration, the vibration member has a plane portion having an appropriate area for mounting the weight, and the weight extends along a direction in which the vibration member protrudes from the face material support portion. Further, it may be provided with an arbitrary weight balance on both sides of the center line of the plane portion. Since the weight can be attached to and detached from the vibrating member, it can be appropriately installed so as to achieve a desired weight balance. Similarly, the vibration member has a plane portion having an appropriate area for mounting the weight, and the weight is provided with a weight balance that is biased with respect to the entire surface of the plane portion. Can be.

  The weight balance biased with respect to the entire plane portion in the above is based on the center line with respect to the plane portion along the direction in which the vibration member protrudes from the face material support portion, and is biased in the direction perpendicular to the center line. In addition to a certain case, it includes a case where it is biased in a direction parallel to the center line, and further includes a state where it is biased in both parallel and orthogonal directions. That is, there are cases where weights having different weights are arranged on both sides of the center line, or where the center of gravity of a lump of weights is arranged in a direction parallel to or perpendicular to the center line. Furthermore, there may be a case where the longitudinal direction of a lump of rectangular weights is installed in a horned shape with respect to the center line.

  As described above, in the invention in which the weight is fixed to the vibration member, the face material abutting portion and the vibration member are integrally configured by a metal plate member, and the metal plate shape The member can be configured to be divided into the face member abutting portion that comes into contact with the face member by bending or bending the member and the vibration member that maintains an appropriate distance from the face member. In this case, the vibration member can be configured to bend obliquely from the boundary with the face material abutting portion. In addition, the face material contact portion and the vibration member are substantially U-shaped. The base material is divided into a base end portion and a free end portion with the return position as a boundary, the face material abutting portion is formed by the base end portion, and the vibration member is formed by the free end portion. You may comprise so that it may form. Furthermore, the vibrating member may be configured to be folded back into a substantially U shape at one or more locations.

  Further, in the invention having the above-described configuration, the mounting means is integrally configured with the face material abutting portion and the vibration member by the metal plate-like member, and the mounting means includes the face material support portion. You may comprise so that it may be mounted | worn with this face material support part by being pinched | interposed between the said face materials. At this time, the mounting means may function as the face material contact portion. In addition, the base end portion indicates an appropriate range from the folding position to the base end side, and the free end portion indicates an appropriate range from the folding position to the free end side, and does not indicate a local end portion. Absent.

  In the invention having the above-described configuration, the mounting means includes a protective member having an appropriate area at a position farther from the face material than the oscillation means, and the protective member is disposed between the face material and the oscillation means. It can be set as the structure which forms a vibration possible area | region.

  In the case of the above-described configuration, in the case where members irrelevant to vibration suppression such as a heat insulating material are provided on the back surface side of the face material, it is possible to prevent these members from coming into contact with the oscillation means. In addition, as a protection member, it can comprise with the plate-shaped member provided substantially parallel to the face material. This is because if an appropriate space is provided between the face materials, a space in which the oscillation means can vibrate is secured in a region where the space is formed.

  And the said vibration member or the said metal plate-shaped member in each said structure can be comprised with spring steel. In this case, the vibration member configured with an appropriate space between the face material can be made to be able to vibrate by spring steel. In addition, it is preferable that the oscillating means in each of the above configurations is configured symmetrically about the face material support portion. This is because the vibration of the face material located on both sides thereof can be transmitted to the oscillating means by mounting at one place on the face material supporting part, and the vibration reduced by the oscillating means is targeted for the vibration of the same frequency. Because it can be done.

  In the said structure, it can be set as the structure which provides the urging means which presses a face material contact part toward a face material. In this case, the urging unit is configured to be supported by the mounting unit, and can be configured by a part of the mounting unit. In particular, when the mounting means and the face material abutting portion are made of a single material, the mounting means and the face material contact may be pressed by forming an elastically deformable region between them. When the contact portion is configured separately, the contact portion may be protruded from the mounting means. In this case, it is preferable that the face material abutting portion (including the vibration member continuous therewith) is locked in a rotatable state with respect to the mounting means. In any case, the pressing means can be configured in a plate shape, and can be configured to bend so that the plate-shaped member bulges toward the face material contact portion.

  According to the above configuration, the face material abutting portion is pressed toward the face material, and the face material abutting portion can reliably abut a wide range of the region that should be in contact with the face material. It is possible to reliably perform transmission when the face material vibrates. In addition, the face material is prevented from changing the contact state between the face material and the face material contact portion due to repeated vibration, and the vibration transmission of the face material by the face material contact portion is stable for a long time. Can be made. In the case where the mounting means and the face material abutting portion are configured separately, the face material abutting portion is rotatable relative to the mounting means. Regardless of strength, an appropriate angle is obtained by rotation, and the contact with the face material is possible.

  According to the present invention, since the vibration damping device is configured to be attached to the face material support portion, it can be installed very easily as compared with the case of being attached to the surface of the face material. In particular, since it is not necessary to install a large number of vibration control devices for each of the face materials through which vibration propagates, it is possible to save labor. In addition, since the vibration is reduced by resonance (resonance) by the oscillation means, particularly the vibration member and the weight, by adjusting the length of the vibration member, the weight of the weight, or both, It is possible to oscillate at a specific frequency, and to reduce noise and the like that are amplified at a frequency specific to a building (surface material specific). By adjusting the frequency at this time, vibration at a low frequency is enabled, so that low frequency vibration of 20 Hz to 400 Hz, which is an unpleasant noise among daily noises, can be reduced.

  Further, according to the invention of the configuration in which the urging means is provided between the mounting means and the face material abutting portion, the urging force that the urging means presses against the face material against the face material abutting portion is applied. Therefore, in the state where the vibration damping device is mounted on the face material support part, the face material contact part can be brought into close contact with the face material, and thereby the face material contact part comes into contact with the face material in a wide range. The vibration of the face material can be transmitted efficiently. In addition, daily noise in a building structure is transmitted exclusively from a wall or ceiling, but the face material constituting the wall or ceiling may not necessarily be a smooth flat surface. Even in this case, the face material abutting portion can be suitably abutted.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a structure of a building to which a vibration damping device is attached. The figure shows an example in which the vibration damping device 1 is mounted, in which the face material 2 is a ceiling material and the face material support portion 3 is a field edge. By replacing the ceiling material with a wall surface material, and replacing the field edge with a wall surface base rail, the wall surface can be used in the same manner. I will explain. In addition, as a general ceiling structure, as shown in the figure, a field edge receiver 6 is supported by a hanger 5 attached to a lower part of a suspension bolt 4 provided on a beam or the like of a building. ) Is configured to be supported by the clip 7 with respect to the field edge receiver 6. The vibration damping device 1 is supported by a base rail such as a field edge, and is not provided on the surface of the ceiling or wall surface, but is provided on the back side thereof.

  The vibration damping device 1 of the present embodiment is attached to the face material support portion (field edge) 3. As an example, the face material (ceiling material) 2 and the face material support portion (field edge) 3 are provided. The state of being sandwiched between the two is shown. This clamping state may be supported only by fixing the face material (ceiling material) 2 to the face material support part (field edge) 3, but the vibration damping device 1 and the face material support part (field edge) 3 may be temporarily fixed (adhering with a double-sided tape or the like), and finally held by fixing the face material (ceiling material) 2. In addition, the face material (ceiling material) 2 used for a general building structure is firmly fixed to the face material support portion (field edge) 3 by a number of screws, The sandwiched state can be strong. In addition, naturally, although the face material support part (field edge) 3 in a figure has illustrated the thing made from light-weight shape steel, it may be made from wood other than light-weight shape steel. Further, the vibration damping device 1 can be fixed to the face material support portion (field edge) 3 in various forms as will be described later. Further, even when the vibration damping device 1 is clamped, it is fixed by screwing or the like separately. Therefore, it may be firmly fixed.

<First Embodiment>
Here, details of the vibration damping device 1 according to the first embodiment will be described. 2A and 2B are views showing the present embodiment, in which FIG. 2A is a perspective view, and FIG. 2B is a front view of a state in which the face material support is mounted. As shown in FIG. 2 (a), in the present embodiment, the tip edges are curved in directions opposite to each other at two appropriate positions 11 and 12 from both ends of a thin plate-like member. , Approximately U-shaped. A region located in the middle of the two appropriate positions (the portions bent at the positions are referred to as bending portions) 11 and 12 is the base end portion 10a, and the tip ends are the free end portions 10b and 10c. Since the base end portion 10a is fixedly supported, the base end portion 10a functions as a base portion, and the free end portions 10b and 10c are continuous to the base end portion 10a, but are not particularly fixed and can freely vibrate. The free end portions 10b and 10c are formed in a state of having an appropriate distance H1 between the flat end portion 10a and the base end portion 10a. The flat base end portion 10a constitutes one continuous flat surface, and among these, the region 13 located in the center is a portion used for clamping with the face material support portion, and this is the face material support. It is one form of the attachment means with respect to a part. Further, on both sides of the central region 13 of the base end portion 10a, there are plane regions 14 and 15 that are continuous to the central region 13, and the surfaces (lower surfaces in the figure) abut against the face material. It functions as a contact part. Such a form of forming the face material abutting portion is one form of a state in which it is directly supported by the mounting means. In the case of the present embodiment, the entire base end portion 10a including the central region 13 can be brought into contact with the face material, and the base end portion 10a functions as a mounting means and is in contact with the face material. It is the structure which can function also as a part, and also when using both functions, it is one form of the state in which both were supported directly.

  The free end portions 10b and 10c are continuous to the base end portion 10a only by the bending portions 11 and 12, and due to their elasticity, the bending portions 11 and 12 are used as base points from the bending portions 11 and 12 to the tip end. The range of can be vibrated. Therefore, the free end portions 10b and 10c function as vibration members. The oscillating means 16 and 17 are configured by fixing the weights 8 and 9 to appropriate portions of the free end portions 10b and 10c. As described above, the curved portions 11 and 12 do not have a special function, and the configuration is such that the base end portion 10a and the free end portions 10b and 10c are merely separated so as to contact the face material. The oscillating means 16 and 17 are directly connected to the part. The weights 8 and 9 constituting the oscillating means 16 and 17 influence the vibration state of the free ends 10b and 10c, and adjust the vibration energy and the vibration frequency. That is, the vibration energy for vibrating the free ends 10b and 10c depends on the weights of the weights 8 and 9, and the vibration frequency changes in combination with the flexibility of the free ends 10b and 10c. To do. That is, when the weights 8 and 9 are increased in weight, vibrations are generated at low frequencies, and when the weights are reduced, vibrations are generated at high frequencies. Therefore, the weights are changed / adjusted according to the frequency to be reduced. .

  In addition, the plate-shaped member in this embodiment is comprised with spring steel, and the vibration of free end part 10b, 10c can produce the amplitude according to the spring constant by spring steel. The areas of the free ends 10b and 10c and the sizes (weights) of the weights 8 and 9 are symmetrical on both sides, and are provided so that the vibration states of both the oscillation means 16 and 17 are the same. ing. The plate-like member may not be spring steel but may be provided with other materials as long as they have the same kind of properties. For example, a resin material having a flexible elastic force may be used.

  FIG. 2B shows a state where the vibration damping device 1 of the present embodiment is supported by the face material support portion 3. As shown in this figure, the center region 13 of the base end portion 10a is supported by the face material support portion 3 by being sandwiched between the face material 2 and the face material support portion 3. At this time, the surface of the central region 13 (lower surface in the drawing) and the surfaces of the flat regions 14 and 15 (lower surface in the drawing) are in contact with the face material 2 by the clamping. Due to these contact with the face material 2, the vibration of the face material 2 is transmitted to the base end portions 10a and further to the free end portions 10b and 10c.

  This vibration transmission oscillates by resonating in the oscillation means 16 and 17. That is, the oscillating means 16 and 17 do not have a driving force by themselves, but operate by receiving transmission of guidance. When the frequency when the face material 2 vibrates approaches the vibration frequency of the oscillating means 16 and 17 by oscillating by resonance (resonance), the oscillating means 16 and 17 (free ends 10b and 10c). Will oscillate. The face material 2 in the building structure has a specific frequency, and the vibration of the face material 2 can be reduced by adjusting the frequencies of the oscillation means 16 and 17 to the natural frequency. is there. The reduction is due to the fact that the vibration energy of the face material 2 is absorbed by the weights 8 and 9, and the absorbed energy is proportional to the weight of the weights 8 and 9. Therefore, the greater the weight of the weights 8 and 9, the more the vibration reduction effect can be expected. However, since the frequency is adjusted by the balance between the flexibility of the free ends 10b and 10c and the weight of the weights 8 and 9, it is expected that only the weights 8 and 9 cannot be increased. Therefore, when absorbing large vibration energy, the number of vibration damping devices 1 to be mounted is increased.

  Since the first embodiment of the present invention is as described above, the back surface of the face material 2 is supported by supporting the vibration damping device 1 of this embodiment on the face material support portion 3 (sandwiched with the face material 2). On the side, the face material abutting portions 14 and 15 (or the entire region of the base end portion 10a) that abut against the face material 2 transmit the vibration of the face material 2 to the oscillating means 16 and 17, and in response to the vibration, 17 can be vibrated. Therefore, it can be mounted at the place where the face material support 3 is installed, and it is not necessary to attach a plurality of damper weights to the back surface side of the face material 2. In addition, because of its structure, weights 8 and 9 larger than the damper weight can be used, so that the absorption rate of vibration energy is high and the effect of reducing noise and the like is great.

  In the above embodiment, the weights 8 and 9 are provided along the leading edges of the free end portions 10b and 10c in the drawing, but this is for showing a state where the weights 8 and 9 vibrate. The position is arbitrary. In particular, the vibration frequency can be varied according to the fixing positions of the weights 8 and 9 at the free ends 10b and 10c. In other words, the frequency increases when the curved portions 11 and 12 are brought close to each other, and the frequency becomes lower when the curved portions 11 and 12 are brought closer to the leading edge. Therefore, by providing the larger weights 8 and 9 closer to the curved portions 11 and 12 than the front end edges, the absorption rate of vibration energy can be improved even at the same frequency.

<Modification of First Embodiment>
Here, a modification of the first embodiment will be described. The modification is configured to have a biasing means for the face material abutting portion, and FIG. 3 is an embodiment having a configuration for biasing the face material abutting portion supported directly by the mounting means. FIG. 4 shows an embodiment in which a deformation region is interposed between the mounting means and the face material contact portion, and the face material contact portion is indirectly supported by the mounting means.

  In the modification shown in FIG. 3, the flat portion (surface) is formed from the boundary between the central region (mounting means) 13 of the base end portion 10 a and the flat regions (face material abutting portions) 14, 15 continuous on both sides thereof. The material abutting portions) 14 and 15 are inclined, and the direction of the inclination is the direction in which the curved portions 11 and 12 approach the face material 2 (FIGS. 3A and 3B). reference). The base end portion 10a is made of an elastically deformable material (for example, spring steel), and the inclined state can be appropriately deformed by forcibly elastically deforming.

  As described above, when the vibration damping device 1 is brought into contact with the face material 2 without forcible force by inclining the plane regions 14 and 15, only the vicinity of the curved portions 11 and 12 comes into contact with the face material 2. However, by attaching the central region (mounting means) 13 to the face material support portion (field edge) 3 (holding between the face material 2 and the field edge 3), the central region (mounting means) 13 becomes At this time, the flat regions (face material contact portions) 14 and 15 are elastically deformed from the inclined portions and deformed into a flat state (or a state close to flat) (FIG. 3). (See (c)). Due to the elastic deformation at this time, the planar regions (face material contact portions) 14 and 15 are urged in the restoring direction, and the planar regions (face material contact portions) 14 and 15 are applied to the face material 2. It will be in the pressed state. As a result, the surfaces of the planar regions (face material contact portions) 14 and 15 are brought into close contact with the face material 2, and a good contact state can be maintained.

  In the modification shown in FIG. 4, the deformation regions 10d and 10e are interposed between the central region (mounting means) 13 and the flat regions (face material contact portions) 14 and 15 of the base end portion 10a. The deformation regions 10d and 10e are formed in a cross-sectional mountain shape by an elastically deformable material (see FIG. 4A). Such a form can be said to be one form in which the mounting means 13 and the face material abutting portion 14 are continuously connected. The reason why the deformation regions 10d and 10e have a mountain-shaped cross section is to provide a movable region accompanying elastic deformation, and the planar regions (surface material contact portions) 14 and 15 contact the surface material 2. This is because the deformation regions 10 d and 10 e are not brought into contact with the face material 2. Therefore, the shape of the cross-sectional mountain shape may be a cross-sectional arc shape or a bellows shape.

  As described above, by providing the deformation regions 10 d and 10 e, the planar regions (face material contact portions) 14 and 15 are inclined in advance with respect to the central region (mounting means) 13. (See FIG. 4 (a)). The direction of the inclination is the direction in which the curved portions 11 and 12 approach the face material 2 (see FIG. 4B), as in the modification in FIG. Means) 13 is forcibly brought into contact with the face material 2 by sandwiching the region 13 between the face material 2 and the face material support part 3. 15 is in close contact with the face material 2 while obtaining an urging force (see FIG. 4C). Due to this urging force (restoring force accompanying elastic deformation), the planar regions (face material abutting portions) 14 and 15 are in close contact with the face material 2 within a suitable range and can sufficiently transmit the vibration of the face material 2. It becomes.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. FIG. 5 is a diagram showing this embodiment. FIG. 5A is a perspective view, and FIG. 5B is a front view of a state in which the face material support is mounted. As shown in these drawings, the vibration damping device 100 of the present embodiment is provided with mounting means 113 having a substantially U-shaped cross section for mounting on the face material support 2. The support means 113 includes a portion that surrounds the face material support portion 2 from three locations, and locking portions 130 a and 130 b for locking at a boundary portion between the face material 2. By attaching to the face material support part 3 from the side where the locking parts 130a and 130b are provided, the lock parts 130a and 130b lock the boundary part with the face material 2, and the whole face material support part 3 can be mounted.

  Further, the mounting means 113 is provided with planar protection members 118 and 119 protruding toward the oscillation means 116 and 117. The protective members 118 and 119 are provided with an appropriate distance H2 between the upper portions of the oscillation means 116 and 117, and are sufficiently between the weights 108 and 109 fixed to the oscillation means 116 and 117. A large space. By having a space between the weights 108 and 109, a region where the oscillation means 116 and 117 can oscillate (vibration members (free end portions) 110b and 110c vibrate) is secured. Securing such a region is suitable for avoiding contact with a heat insulating material or the like provided on the back side of the ceiling or wall surface in the building structure.

  Further, in the present embodiment, the face material contact portions 114 and 115 and the oscillation means 116 and 117 are arranged together on both sides of the mounting means 113. The face material abutting portions 114 and 115 and the oscillation means 116 and 117 are provided separately from the mounting means 113, and a part (base) 110 a of the face material abutting portions 114 and 115 is attached to the mounting means 113. Are integrated with each other by fastening or welding. Since the face material abutting portions 114 and 115 and the oscillation means 116 and 117 are provided separately and attached to the attachment means 113, the face material abutting portions 114 and 115 are arranged so that the face material support portion 3 is a surface. In a region deviating from the position where the material 2 is supported, the surface material 2 is brought into contact. Thereby, the vibration of the face material 2 can be directly transmitted to the oscillating means 116 and 117 without passing through the face material support part 3 (without being transmitted to the face material support part 3). In addition, the above-described fastening includes a method of fastening with bolts and nuts, and may be fastening with rivets or the like, and welding may be spot welding in addition to welding the edge. As described above, the aspect in which a part (base) 110 a of the face material abutting portions 114 and 115 is connected to a part of the mounting means 113 is such that the face material abutting portions 114 and 115 are indirectly attached by the mounting means 113. It is one form when it is supported.

  By separately forming the mounting means 113, the face material abutting portions 114 and 115, and the oscillation means 116 and 117 as in the above configuration, both can be made of different materials. For example, only the face material abutting portions 114 and 115 and the oscillating means 116 and 117 can be made of spring steel, and other materials can be used for the mounting means 113. With such a configuration, the vibration transmission action and the oscillation action by the face material abutting portions 114 and 115 and the oscillation means 116 and 117 can be secured by spring steel. Furthermore, the dimensional accuracy can be improved by individual manufacturing of the part. In addition, it can replace with spring steel and can also be comprised with a resin material, and it is good also considering only the mounting means 113 as a metal material in this case.

  Since the present embodiment is configured as described above, the oscillating means 116 and 117 function in the same manner as those in the first embodiment 16 and 17, and are provided with protective members 118 and 119. As a result, the movable range of the oscillation means 116 and 117 can be secured. Moreover, since it becomes easy to mount the vibration damping device 100 on the face material support portion 3 and the attachment means 113 has a U-shaped cross section, after the face material 2 is installed on the face material support portion 3, Can also be installed. Therefore, after the installation work, after confirming a situation in which vibration due to noise or the like is reduced, additional installation or replacement of the vibration damping device 100 becomes easy.

<Third Embodiment>
Next, a third embodiment will be described. FIG. 6 is a diagram showing this embodiment. 6 (a) is a perspective view, FIG. 6 (b) is a front view showing a state where it is mounted on a face material support portion, and FIG. 6 (c) shows a use state. As shown in FIGS. 6A and 6B, this embodiment is basically the same as the second embodiment, but the forms of the oscillation means 216 and 217 are different, and the face material is used. The contact portions 214 and 215 are different from each other in that the contact portions 214 and 215 are provided integrally with the locking portions 230a and 230b of the mounting unit 213.

  The vibration members (free end portions) 210b and 210c in the vibration damping device 200 of the present embodiment are not curved, and have a shape protruding from the side with a step from the face material abutting portions 214 and 215. . By providing the step, the vibration members (free end portions) 210b and 210c are configured to vibrate without contacting the face material 2, and the weights 208 and 209 that receive the vibration are the vibration member (free end). Portion) 210b and 210c are fixed to the upper surface of the vibration member (free end portions) 210b and 210c so as to protrude outward from the edges. Furthermore, the weights 208 and 209 are formed in a plate shape so that a plurality of the weights 208 and 209 can be arranged in a stacked state, and are projected from the edges of the vibration members (free ends) 210b and 210c. It can be increased or decreased according to the weight of one sheet.

  In addition, the locking portions 230a and 230b of the present embodiment do not uniquely lock the face material support portion 3, but are in contact with the face material 2 integrally with the face material contact portions 214 and 215, It is assumed that it is locked by clamping with the face material support part 3. Therefore, the mounting means 213 can be locked to the face material support portion 3 and can also function as a face material contact portion.

  Since the mounting means 213 is configured as described above, when mounting to the face material support portion 3, as shown in FIG. 6C, the upper portion of the mounting means 213 is artificially curved. It will be. That is, the upper part of the mounting means 213 is formed by two strip-shaped portions as shown in the figure, and if it is a spring steel or a material having flexibility even if it is not a spring steel (thin wall A metal material or a resin material) can be sufficiently curved. Then, by curving in this way, both ends of the locking portions 230a and 230b are greatly separated and can be moved to the side where the face material 2 is installed through the face material support portion 3. Then, after moving to the mounting position, the face material support portion 3 can be held by the entire mounting member 213 together with the locking portions 230a and 230b by restoring the curved state to the original state. It is.

  Since the present embodiment has such a configuration, it is easy to mount the vibration damping device 200 as in the second embodiment. In particular, in the present embodiment, since the locking portions 230a and 230b are finally held between the face material 2 and the face material support portion 3, the gripped state is regarded as a temporarily fixed state and is held. This state can be regarded as a firmly fixed state. And since such a temporary fix | stop state can be performed easily, installation of the several damping device 200 will become a very simple thing. Furthermore, since the weights 208 and 209 can be increased and decreased, the vibration frequency and the like in the oscillation means 216 and 217 can be easily adjusted, and can be adjusted on the spot at a site where the frequency unique to the building (surface material) is different. In addition, the number of weights 208 and 209 can be changed at a later date.

  In the present embodiment, as shown in FIG. 7, the mounting means 213 and other portions are individually formed, and both are integrated by fastening or welding. As the parts to be joined by fastening or welding or the like, the standing part 210a which is erected by bending a part of the face material abutting parts 214 and 215 and the side parts 211 and 212 of the mounting means 213 are used. . Note that tightening includes a method of tightening with bolts and nuts, and may be crimping with rivets or the like, and welding may be spot welding in addition to welding the edge. Here, the locking portions 230a and 230b are configured by a part of the face material contact portions 214 and 215, and are configured to partially protrude. And the standing part 210a is comprised between the latching | locking parts 230a and 230b made to protrude in several places (a figure is two places).

  In the case of the said structure, both can be produced with a different material. For example, the members excluding the mounting means 213 can be made of spring steel, or can be made of a resin material, and can be integrated with the mounting member 213 made of a metal material. Alternatively, since the mounting means 213 needs to be bent at the time of mounting (see FIG. 6C), the mounting means 213 may be made of a resin material and the other parts may be made of spring steel. In this way, it is possible to select either the same material or different materials, and it is possible to select appropriately in terms of manufacturing cost. The locking portions 230a and 230b are formed on the face material support portion 3 when the mounting means 213 is mounted. Therefore, the locking portions 230a and 230b constitute a part of the mounting means 213, but the portions excluding the locking portions 230a and 230b. Is the mounting means, the face material abutting portions 214 and 215 are indirectly supported by the mounting means 213 via the standing portion 210a. This is one form of being indirectly supported.

<Modification of Third Embodiment>
Here, a modification of the third embodiment will be described. FIG. 8 shows a modification of one of the face material contact portions 215 (including the locking portion 230b) and the vibration member (free end portion) 210c in the third embodiment. In the modification shown in FIG. 8A, substantially U-shaped ribs 240 and 250 are formed on the base end edge of the vibration member (free end portion) 210c. The ribs 240 and 250 are provided by drawing from the front surface side to the back surface side of the vibration member (free end portion) 210c. Although only the concave portion is shown in the figure, convex ribs are formed on the back surface side. The vibration member (free end portion) 210c vibrates repeatedly during oscillation, and the vibration moves up and down around a boundary (base end edge) with the face material abutting portion 215. Therefore, in the case of forming with a relatively thin material, it causes wear (fatigue failure) of the base end edge, and therefore the base end portion is reinforced.

  For the same reason, as shown in FIG. 8B, partial ribs 240 a and 240 b are provided on both the base end edge of the vibration member (free end portion) 210 c and the base end edge of the face material abutting portion 215. , 250a, 250b. The ribs 240a and 250a provided on the base end edge of the vibration member (free end portion) 210c are drawn from the upper surface to the rear surface side, and the upper surface side is concave, but the rear surface side is convex. On the other hand, the ribs 240b and 250b provided on the base end side of the face material abutting portion 215a are drawn from the back side, and the upper surface is convex. Note that these ribs 240a to 250b are all drawn into a triangular pyramid shape, and are provided at several locations to maintain strength.

  The embodiments of the present invention are as described above, and any of the embodiments has a region in contact with the face material, and the oscillation means vibrates in response to vibration transmitted from this region. It is possible to reduce this. These embodiments are examples of the present invention, and the present invention is not limited to these embodiments. Therefore, it is possible to change the configuration of a part of the above embodiment to change the shape.

<Fourth Embodiment>
Therefore, a fourth embodiment, which is a modification of the second embodiment, will be described as a representative example of the modification. 9 and 10 show a first modification (fourth embodiment), and FIGS. 11 and 12 show a second modification (fifth embodiment). As described above, in the second embodiment, the face material abutting portions 114 and 115 and the oscillating means 116 and 117 are provided separately from the mounting means 113, and a part (base portion) of the face material abutting portions 114 and 115 is provided. 110a was fastened or welded to the mounting means 113.

  In the fourth embodiment (first modification), as shown in FIG. 9, the face material abutting portions 114 and 115 are continuously provided on the wall surface of the mounting means 113, and the middle thereof. The deformation areas 110d and 110e are formed at the positions. The deformation regions 110d and 110e are formed in a cross-sectional mountain shape as in the modification of the first embodiment (FIG. 4), and the urging force (face material) is applied to the face material contact portions 114 and 115. It is provided to give a pressing force).

  That is, as shown in FIG. 10A, the deformation regions 110d and 110e are elastically deformable, and the face material contact portions 114 and 115 are provided to be inclined with respect to the contact virtual surface L. By elastically deforming the deformation regions 110d and 110e, an urging force (pressing force) can be applied to the face material abutting portions 114 and 115 by the restoring force. This is the biasing means. The elastic deformation of the deformation regions 110d and 110e assumes that the face material contact portions 114 and 115 are displaced to the position of the contact virtual surface L, and the face material contact portions 114 and 115 are just in contact. When displacing until it coincides with the virtual surface L, the surfaces (lower surfaces in the drawing) of the two face material abutting portions 114 and 115 located on both sides of the mounting means 113 are on a single plane (on a straight line in the drawing). Has been adjusted.

  10B, when the mounting means 113 is mounted on the face material support portion 3 and the face material 2 is installed on the face material support portion 3, the locking portions 130a and 130b are used as a reference. The back surface (upper surface in the drawing) of the face material 2 induces the inclined state of the face material abutting portions 114 and 115 to a flat state and forcibly deforms the deformation regions 110d and 110e. Then, a restoring force is generated by this deformation, and an urging force that presses the face material abutting portions 114 and 115 toward the face material 3 is generated. At this time, the surface (lower surface in the figure) of the face material abutting portions 114 and 115 coincides with the virtual contact surface L, and therefore coincides with the back surface (upper surface in the figure) of the face material 2. It will be able to adhere in good condition. By adhering while having such an urging force, it is possible to make contact in a wide range even when there is a slight shift or unevenness on the surface when the face material 2 is mounted, and vibration of the face material 2 is suppressed. It is possible to transmit to the contact portions 114 and 115. Since this embodiment is a modification of the second embodiment, the oscillating means 116 and 117 are weighted to the free ends 110b and 110c in a curved state from the face material abutting portions 114 and 115, respectively. 109 are fixed, and protective members 118 and 119 are provided at intervals from the oscillation means 116 and 117. Here, a state where a wooden crosspiece is used as the face material support portion 3 is shown. In the case of a wooden cross, there is a tendency that it does not vibrate compared to a light-weight shaped steel field edge, etc., and vibration transmission from the face material abutting portions 114 and 115 becomes important, so the above configuration becomes more suitable. .

<Fifth Embodiment>
In the fifth embodiment (second modification of the second embodiment), as shown in FIGS. 11A and 11B, the face material contact portions 114 and 115 and the oscillation means 116, 117 is provided separately from the mounting means 113, both of which are partially locked and press the face material abutting portions 114, 115 by the protruding members 131 a, 132 a, 131 b, 132 b protruding from the mounting means 113. It is comprised so that it may do. Locking of the face material abutting portions 114 and 115 with respect to the mounting means 113 may take any form as long as the face material abutting portions 114 and 115 can be rotated within an appropriate range. In addition, there may be a form in which through holes 110h and 110i are provided in part (base portions) 110f and 110g of the face material abutting portions 114 and 115 and are latched by locking pieces 133a (and 133b) protruding from the mounting means 113. .

  Here, as shown in FIG. 12A, the base portions 110f and 110g of the face material abutting portions 114 and 115 are rotatably locked to locking pieces 113a and 113b provided on the mounting means 113, respectively. Moreover, it will be in the state which inclined by being pressed by protrusion member 131a, 132a, 131b, 132b which protrudes from the mounting means 113. FIG. The projecting members 131a, 132a, 131b, and 132b are made of elastic members that can be elastically deformed. When changing to the same state as the surface L, the projecting members 131a, 132a, 131b, 132b are elastically deformed. A restoring force is generated along with this elastic deformation, and an urging force (pressing force) can be applied to the face material abutting portions 114 and 115. This is the biasing means. The change in the inclined state of the face material abutting portions 114 and 115 is regulated by the rotation direction of the locking pieces 113a and 113b, but between the through holes 110h and 110i and the locking pieces 113a and 113b. Is provided with sufficient play, and the rotation axis during rotation is not strict. Therefore, the rotation angle of the face material abutting portions 114 and 115 due to the rotation can be changed as appropriate according to the state of the face material 2 that abuts.

  Accordingly, as shown in FIG. 12B, when the mounting means 113 is mounted on the face material support portion 3 and the face material 3 is further installed, the face material contact portions 114 and 115 are inclined from the inclined surface. It will rotate so that it may correspond to the back surface (upper surface in the figure) of the material 2. At this time, the projecting members 131a, 132a, 131b, and 132b are elastically deformed, and are urged in a direction in which the projecting members 131a, 132a, 131b, and 132b are rotated in the opposite direction with respect to the face material contact portions 114 and 115. The rotation of the face material abutting portions 114 and 115 is performed with the locking pieces 113a and 113b as axes as described above, but the protruding members 131a, 132a, 131b and 132b are simply the face material abutting portions 114. , 115 is only pressed, and the face material abutting portions 114, 115 are stabilized in a state of being in close contact with the back surface (upper surface in the drawing) of the face material 2 in a wide range. Due to such a stable contact state, the contact with a wide range in a suitable state is possible depending on the relative relationship with the back surface (upper surface in the drawing) of the face material 2. In this embodiment as well, since this is a modification of the second embodiment, the configuration of the oscillation means 116 and 117 is changed to the free ends 110b and 110c in a state of being curved from the face material contact portions 114 and 115. The weights 108 and 109 are fixed and the protective members 118 and 119 are provided as in the first example. Also in this example, a wooden cross is illustrated as the face material support portion 3, and it is shown that vibration transmission from the face material contact portions 114 and 115 is important.

<Sixth Embodiment>
Moreover, it can be set as 6th Embodiment by deform | transforming a part of said 5th Embodiment. FIG. 13 shows a sixth embodiment. As shown in this figure, the basic configuration of the vibration damping device 100 of this embodiment is the same as that of the fifth embodiment. That is, the face material abutting portions 114 and 115 and the oscillation means 116 and 117 are provided separately from the mounting means 113, and the face material abutting portions 114 and 115 are indirectly supported by the mounting means 113. is there. Further, the face material abutting portions 114 and 115 are configured to be pressed by projecting members (biasing means) 131a and 131b projecting from the mounting means 113.

  The urging means 131a and 131b of the present embodiment are configured by a single wide-area plate-like member, and as a result, the urging force acts integrally on the face material abutting portions 114 and 115. Thus, the pressing force can be applied to the face material abutting portions 114 and 115 evenly. Further, since the surface material abutting portions 114 and 115 (actually surface materials) are bulged (bulged) and gently curved, first, the surface material abutting portions 114 and 115 115 can be easily inserted into the gap between the vibration members 110b and 110c, and secondly, the insertion state can be maintained even at the time of elastic deformation accompanying urging.

  In the present embodiment, since the urging means 131a and 131b are configured by a plate member having a large area as described above, a part of the urging means 131a and 131b is cut out and partially separated, whereby the separated part is used. The locking portions 133a and 133b can be configured. And as for the face material contact parts 114 and 115, the through-holes 110h and 110i which partially penetrated the part (base parts 110f and 110g) are locked to the locking pieces 133a and 133b. The urging means 131a and 131b can be rotated in the urging direction. It should be noted that the surface material abutting portions 114 and 115 may be locked in any form as long as the surface material abutting portions 114 and 115 can rotate within an appropriate range. In the example of the figure, a configuration in which the locking portions 133a and 133b at one central portion and the through holes 110h and 110i corresponding to the central locking portions is shown is locked at two locations near both side edges. The engaging portions 133a and 133b may be configured as in the fifth embodiment.

  Accordingly, as shown in FIG. 14A, the face material abutting portions 114 and 115 are pressed by the urging means 131a and 131b and are inclined with respect to the abutting virtual surface L. By rotating so as to resist the urging of the means 131a and 131b, the state can be changed to the same state as the virtual contact surface L. Accordingly, as shown in FIG. 12B, when the mounting means 113 is mounted on the face material support portion 3 and the face material 3 is further installed, the face material contact portions 114 and 115 are inclined from the inclined surface. It will rotate so that it may correspond to the back surface (upper surface in the figure) of the material 2. Also in this embodiment, as in the fifth embodiment, the biasing means 131a and 131b are elastically deformed to bias the face material abutting portions 114 and 115 by their restoring force. In this embodiment, the protective member is not provided as in the second or fifth embodiment, but a configuration in which these are provided may be employed.

<Modification of Sixth Embodiment>
The sixth embodiment can be further modified. FIG. 15 shows a modification thereof. As shown in this figure, this modification has a configuration in which the oscillating member 110b is projected from one side (one of both sides) with the mounting means 113 as the center. Accordingly, only one of the face material abutting portions 114 continuous with the oscillation member 110b is urged by the urging means 131a. In addition, the oscillation member 110b of this modification includes an intermediate portion 161 provided via the first bending portion 160a with respect to the face material abutting portion 114, and further a second bending portion 160b with respect to the intermediate portion 161. The oscillating means 116 has a configuration in which a weight 108 is installed on the surface of the plane portion 162. This is to lower the frequency by making the tip (free end) side longer than the first curved portion 160a, and to disperse stress acting by vibration in two places.

  Furthermore, in this modified example, since the biasing means on the opposite side is not required, the protection member 118 is configured using this portion. The protection member 118 is configured to bend its periphery in order to ensure strength. Note that a plurality of slightly bulged ribs 140 are provided at the corners of the base end of the protection member 118 and are reinforced so as to protect the oscillation means 116.

  In the case of this modification, as shown in FIG. 16, on one side of the mounting member 113, the face material abutting portion 114 is urged by the urging means 131a as in the sixth embodiment. The state can be changed from a state inclined with respect to the virtual contact surface L (see FIG. 16A) to a state in contact with the back surface of the face material 2 (see FIG. 16B).

  In the case of this type of modification, a damping action is obtained on one side of the face material support 3. Therefore, in the actual installation site, a plurality of vibration control devices 100 are installed while having a predetermined interval in the longitudinal direction of the face material support portion 3, and at that time, the oscillation means 116 are alternately arranged on both sides. In this way, it is possible to obtain a vibration damping action on the face material 3 positioned on both sides of the face material support portion 3. Note that the configuration in which the oscillation member 110b is provided only on one side of the mounting member 113 as described above is not limited to the case where the sixth embodiment is modified. Accordingly, in the first to fifth embodiments and the modifications thereof, the oscillation member can be provided only on one side.

<Modification of oscillation means>
Further, the oscillating means 116 can change the installation state of the weight 108 so that the single vibrating member 110b can vibrate at different frequencies. FIG. 17 illustrates an oscillating means 116 in a modification of the above-described sixth embodiment. As shown in FIG. 17A, the flat portion 162 of the vibration member 110b is provided with long holes 163 and 164 having appropriate intervals and lengths, and the long holes are formed by rivets 165 and 166 that can penetrate the weight 108. The weight 108 can be fixed between 163 and 164.

  Therefore, by arbitrarily selecting the position where the long holes 163 and 164 are used, for example, as shown in FIGS. 7B to 7D, the center line of the plane portion 162 (direction X in which the vibration member protrudes) The weight balance of the weight 108 in the both side directions (Y direction) can be changed on the basis of the line M). In the example of FIG. 7B, the center of gravity from the front end (the end of the free end) of the plane portion 162 is biased by changing the position in the protruding direction (X direction). In the example of FIG. 7C, the weight 108 is installed only on one side of the center line M, and in the example of FIG. 7D, the weights 108a and 108b having different weights are installed on both sides of the center line M. Is provided with a bias in the weight balance.

  With this type of oscillating means 116, the vibration state of the vibrating member 110 b located on both sides of the center line M is different even though it is a single oscillating means 116. Therefore, the oscillating member 110 b is vibrated at different frequencies. be able to. That is, when the weight 108 is heavy or close to the free end, it vibrates at a low frequency, and conversely when the weight 108 is light or away from the free end, it vibrates at a high frequency. It becomes. Thereby, the vibration member 110b can vibrate appropriately according to the frequency at which the face material to be damped actually vibrates. The configuration as described above is not limited to the case of the modification of the sixth embodiment. Accordingly, the weight balance can be similarly changed in the first to sixth embodiments and the modifications thereof.

  Further, unlike the above example, modifications as shown in FIGS. 18 and 19 are possible. That is, as shown in FIG. 18, in the configuration in which the mounting means 313 is sandwiched between the face material 2 and the face material support portion 3, the mounting means 313 is also used as the face material contact portions 314 and 315. is there. That is, the mounting means 313 functions as the face material abutting portions 314 and 315. Further, in this case, the vibration members (free end portions) 310b and 310c are not curved in a U shape, but are configured to protrude from the mounting means 313 to both sides through a step in the orthogonal direction (FIG. 18). (See (a)), a structure that protrudes to both sides through an oblique step (see FIG. 18B), or a structure that protrudes obliquely without any step (see FIG. 18B). For example, see FIG. These are vibration members (free end portions) 310b, 310c linearly projecting to both sides, and the vibration members (free end portions) 310b, 310c are appropriately spaced H1 between the face material 2. Therefore, the same function as in the first embodiment can be exhibited.

  Further, as shown in FIG. 19A, a configuration using a damper weight as the oscillation means may be employed. In this case, the damper weights 460 and 470 are installed on the surfaces of the face material contact portions 414 and 415. In the case of such a configuration, the face material abutting portions 414 and 415 can transmit the vibration of the face material to the damper weights 460 and 470, and the damper weights 460 and 470 function as oscillation means. Since the damper weights 460 and 470 are eventually supported by the mounting means 413, the damper weights 460 and 470 are indirectly attached to the face material only by attaching the mounting means 413 to the face material support portion. It can arrange | position, making it contact. The dampers used for the damper weights 460 and 470 may be rubber dampers or spring dampers. The damper weights 460 and 470 are supported (supported by a gap) by the support provided in the face material abutting portions 414 and 415. It is an aspect of the indirectly continuous form.

  Furthermore, as shown in FIG. 19B, the free ends 10b and 10c in the first embodiment may be configured to be bent in a substantially U shape at a plurality of locations. In this case, the effect of buffering the impact is increased by the fact that there are a plurality of bent portions (locations serving as vibration base points) and the entire free ends 10b and 10c are long. As a result, the oscillating means 16 and 17 vibrate at a low speed, and it is easy to cause resonance (resonance) at a low frequency. In addition, if specific conditions are prepared, a bending part will operate | move separately and the phenomenon which a surface vibrates by a different phase (phase of a delay system) may arise. In this case, it resonates at a portion that vibrates in any of the bendings, and oscillates in response to vibration close to the frequency unique to the building (surface material). In some cases, a resonance phenomenon occurs inside the oscillating means, and the vibration energy absorption rate may be increased by amplification of vibration due to the resonance phenomenon. In this case, if the ends (uppermost plane portions) of the free end portions 10b and 10c and the weights 8 and 9 are defined as the oscillation means 16 and 17, the shock absorbing region or the frequency between the face material abutting portions is defined. A portion to be referred to as an adjustment region is interposed, and this is one aspect of the form in which the oscillation means is indirectly connected to the face material contact portion.

  Note that these modified examples are modifications of the first embodiment (see FIGS. 18 and 19B) and modifications of the third embodiment (see FIG. 19A). Each part which deform | transformed is not limited to these, It can be used also in other embodiment or a modification. Although individual modification modes are not individually illustrated, for example, the modification examples illustrated in FIGS. 18 and 19B can be employed in the second and third embodiments, and the configuration illustrated in FIG. It can be diverted to the first embodiment.
