内側部材２２は、例えば、センタプレート２２ａを有する。センタプレート２２ａは、外側部材２１のサイドプレート２１ａとサイドプレート２１ｂとの間に位置され、サイドプレート２１ａおよびサイドプレート２１ｂから軸方向に離間している。センタプレート２２ａは、回転中心Ａｘ回りの円環状かつ板状に構成され、径方向に広がっている。センタプレート２２ａは、サイドプレート２１ａ，２１ｂと回転中心Ａｘ回りに相対的に回転可能に設けられている。ただし、センタプレート２２ａとサイドプレート２１ａ，２１ｂとの相対的な回転は、例えば、不図示のストッパ同士が当接することなどによって、所定の角度範囲内に限定されている。センタプレート２２ａには、開口部２２ｂが設けられている。図２に示されるように、開口部２２ｂは、例えば、センタプレート２２ａの径方向の外側に向けて開放された切欠部として構成されている。また、開口部２２ｂは、センタプレート２２ａを軸方向に貫通している。センタプレート２２ａの開口部２２ｂとサイドプレート２１ａ，２１ｂの開口部２１ｃ，２１ｄとは、互いに軸方向に重なり合っている。開口部２２ｂには、周方向の一方側の縁部と他方側の縁部との間に第一の弾性部材２３が配置されている。また、センタプレート２２ａの径方向の内側の端部には、凸状の引掛部２２ｃが設けられている。引掛部２２ｃは、センタプレート２２ａの径方向の内側の端部から回転中心Ａｘ側に向かって突出している。センタプレート２２ａ、すなわち内側部材２２は、例えば、金属材料によって構成されうる。   The inner member 22 has, for example, a center plate 22a. The center plate 22a is positioned between the side plate 21a and the side plate 21b of the outer member 21, and is separated from the side plate 21a and the side plate 21b in the axial direction. The center plate 22a is formed in an annular and plate shape around the rotation center Ax and spreads in the radial direction. The center plate 22a is provided so as to be relatively rotatable around the side plates 21a and 21b and the rotation center Ax. However, the relative rotation between the center plate 22a and the side plates 21a and 21b is limited to a predetermined angle range by, for example, contact of stoppers (not shown). The center plate 22a is provided with an opening 22b. As shown in FIG. 2, the opening 22b is configured as a notch that is opened toward the outside in the radial direction of the center plate 22a, for example. Further, the opening 22b penetrates the center plate 22a in the axial direction. The opening 22b of the center plate 22a and the openings 21c and 21d of the side plates 21a and 21b overlap each other in the axial direction. The first elastic member 23 is disposed in the opening 22b between the edge on one side and the edge on the other side in the circumferential direction. A convex hooking portion 22c is provided at the radially inner end of the center plate 22a. The hook 22c protrudes from the radially inner end of the center plate 22a toward the rotation center Ax. The center plate 22a, that is, the inner member 22, can be made of, for example, a metal material.

図１，２に示される第一の弾性部材２３は、例えば、金属材料で構成され、周方向に略沿って延びたコイルばねである。第一の弾性部材２３は、互いに軸方向に重なり合った開口部２１ｃ，２１ｄおよび開口部２２ｂ内に収容され、第一の回転部材２５と第二の回転部材２６とに接続される。このような構成で、開口部２１ｃ，２１ｄの周方向の一方側の縁部と開口部２２ｂの周方向の他方側の縁部とが互いに近付く方向に相対的に回転すると、それら縁部によって第一の弾性部材２３が弾性的に縮む。逆に、開口部２１ｃ，２１ｄおよび開口部２２ｂ内で弾性的に縮んだ状態で、開口部２１ｃ，２１ｄの周方向の一方側の縁部と開口部２２ｂの周方向の他方側の縁部とが互いに遠ざかる方向に相対的に回転すると、第一の弾性部材２３は弾性的に伸びる。すなわち、第一の弾性部材２３は、第一の回転部材２５のサイドプレート２１ａ，２１ｂと第二の回転部材２６のセンタプレート２２ａとの間に挟まれ、回転中心Ａｘ回りの相対的な回転に伴って略周方向に沿って弾性的に伸縮する。第一の弾性部材２３は、弾性的に縮むことによりトルクを圧縮力として蓄え、弾性的に伸びることにより圧縮力をトルクとして放出する。第一の弾性部材２３は、このように、第一の回転部材２５と第二の回転部材２６との間に位置され、第一の回転部材２５と第二の回転部材２６とに周方向に略沿って挟まれて、周方向に略沿って弾性的に伸縮する。ダンパ部１２は、この第一の弾性部材２３の伸縮によってトルク変動を緩和することができる。   The first elastic member 23 shown in FIGS. 1 and 2 is a coil spring made of, for example, a metal material and extending substantially along the circumferential direction. The first elastic member 23 is accommodated in the openings 21 c and 21 d and the opening 22 b that overlap each other in the axial direction, and is connected to the first rotating member 25 and the second rotating member 26. With such a configuration, when the edge on one side in the circumferential direction of the openings 21c and 21d and the edge on the other side in the circumferential direction of the opening 22b rotate relatively to each other, the edges cause the first One elastic member 23 is elastically contracted. Conversely, in a state where the openings 21c and 21d and the opening 22b are elastically contracted, an edge on one side in the circumferential direction of the openings 21c and 21d and an edge on the other side in the circumferential direction of the opening 22b Are relatively rotated in a direction away from each other, the first elastic member 23 is elastically extended. That is, the first elastic member 23 is sandwiched between the side plates 21a and 21b of the first rotating member 25 and the center plate 22a of the second rotating member 26, and is relatively rotated around the rotation center Ax. Accompanying this, it elastically expands and contracts along the substantially circumferential direction. The first elastic member 23 elastically contracts to store torque as a compressive force, and elastically extends to release the compressive force as torque. Thus, the 1st elastic member 23 is located between the 1st rotation member 25 and the 2nd rotation member 26, and the 1st rotation member 25 and the 2nd rotation member 26 are the circumferential direction. It is sandwiched approximately along and elastically expands and contracts approximately along the circumferential direction. The damper portion 12 can relieve torque fluctuation by the expansion and contraction of the first elastic member 23.

The support member 70D includes a wall portion 70m, a wall portion 70n, and a wall portion 70p. The wall portion 70m is positioned between the first cylindrical portion 24b and the fourth weight member 30I, and is configured, for example, in a cylindrical shape along the outer surface of the first cylindrical portion 24b. In the present embodiment, the other side in the axial direction of the wall 70m, that is, the right end in FIG. 16 is connected to the wall 70n, and one side in the axial direction of the wall 70m, ie, the left end in FIG.

<Fourteenth embodiment>
A damper device 1L of the present embodiment shown in FIG. 17 has the same configuration as the damper device 1 of FIG. Therefore, according to this embodiment, the same result and effect based on the same configuration as that of the embodiment of FIG. 1 can be obtained.

ただし、本実施形態では、図１７に示されるように、第二の弾性部材３３Ｇが、板ばねで構成されている。第二の弾性部材３３Ｇは、径方向に沿って延びた棒状に構成されている。第二の弾性部材３３Ｇの一方側の端部３３ａは、第二の回転部材２６の第一の筒状部２４ｂに接続され、第二の弾性部材３３Ｇの他端側の端部３３ｂは、第一の錘部材３２に接続されている。第二の弾性部材３３Ｇは、第二の回転部材２６に弾性変形可能に支持された状態で、第一の錘部材３２を支持している。第二の弾性部材３３Ｇと第一の筒状部２４ｂおよび第一の錘部材３２との結合は、例えば、加硫接着等によってなされる。また、本実施形態では、複数の第二の弾性部材３３Ｇが、互いに間隔をあけて周方向に並んで配置されている。よって、周方向で隣り合う二つの第二の弾性部材３３Ｇの間には、空間が設けられている。複数の第二の弾性部材３３Ｇは、回転中心Ａｘを中心とした放射状に並べられるとともに、周方向に沿って略等角度間隔に並べられている。また、複数の第二の弾性部材３３Ｇは、径方向に互いに重なり合って位置されている。第二の弾性部材３３Ｇは、例えば、軸方向の厚さが周方向に沿った幅よりも薄い板ばねとして構成されている。すなわち、本実施形態では、第二の弾性部材３３Ｇは、厚さ方向の曲げ剛性と厚さ方向と直交する幅方向の曲げ剛性とが異なっている。よって、本実施形態によれば、例えば、ダンパ装置１Ｌに加わる互いに異なる方向の振動に対して異なる減衰特性を得やすい。また、本実施形態では、複数の第二の弾性部材３３Ｇが回転中心Ａｘ回りに互いに間隔を空けて位置されている。よって、本実施形態によれば、一つの第二の弾性部材が回転中心Ａｘ回りの環状に構成される場合と比べて、第二の弾性部材３３Ｇの周方向の変形量を大きくできる場合がある。なお、本実施形態では、第二の弾性部材３３Ｇのみが示されたが、不図示の第三の弾性部材も板バネで構成されうる。   However, in this embodiment, as shown in FIG. 17, the second elastic member 33 </ b> G is configured by a leaf spring. The second elastic member 33G is configured in a rod shape extending along the radial direction. One end portion 33a of the second elastic member 33G is connected to the first cylindrical portion 24b of the second rotating member 26, and the other end portion 33b of the second elastic member 33G is One weight member 32 is connected. The second elastic member 33G supports the first weight member 32 while being supported by the second rotating member 26 so as to be elastically deformable. The second elastic member 33G is coupled to the first cylindrical portion 24b and the first weight member 32 by, for example, vulcanization adhesion or the like. In the present embodiment, the plurality of second elastic members 33G are arranged side by side in the circumferential direction at intervals. Therefore, a space is provided between two second elastic members 33G adjacent in the circumferential direction. The plurality of second elastic members 33G are arranged radially around the rotation center Ax, and are arranged at substantially equal angular intervals along the circumferential direction. The plurality of second elastic members 33G are positioned so as to overlap each other in the radial direction. For example, the second elastic member 33G is configured as a leaf spring in which the axial thickness is thinner than the width along the circumferential direction. That is, in the present embodiment, the second elastic member 33G has a different bending rigidity in the thickness direction and a bending rigidity in the width direction orthogonal to the thickness direction. Therefore, according to the present embodiment, for example, it is easy to obtain different attenuation characteristics with respect to vibrations in different directions applied to the damper device 1L. In the present embodiment, the plurality of second elastic members 33G are positioned at intervals around the rotation center Ax. Therefore, according to the present embodiment, the amount of deformation in the circumferential direction of the second elastic member 33G may be increased as compared with the case where one second elastic member is configured in an annular shape around the rotation center Ax. . In the present embodiment, only the second elastic member 33G is shown, but a third elastic member (not shown) can also be configured by a leaf spring.

The base portion 32t is configured in a cylindrical shape, and is coupled to the radially outer end portion 33b of the second elastic member 33. The first extending portion 32u protrudes inward in the radial direction from one axial side of the base portion 32t, that is, from the left end in FIG. 18, and faces the second elastic member 33 in the axial direction. The first extending portion 32u is formed in an annular and plate shape around the rotation center Ax. The radially inner end 32u1 of the first extension 32u is the radially inner end of the first weight member 32J. In the present embodiment, the support member 41 is provided between the first cylindrical portion 24b and the first extending portion 32u. The support member 41 is located radially inward of the radial center of the second elastic member 33. The position of the center of the second elastic member 33 in the radial direction is indicated by a line B. The support member 41 has a radial direction support part 41a and an axial direction support part 41b. The radial direction support part 41a is also called a cylindrical part, and the axial direction support part 41b is also called a wall part. The radial support part 41a is configured in a cylindrical shape around the rotation center Ax. The radial support portion 41a and the first cylindrical portion 24b are coupled to each other by press-fitting, caulking, hooking, bonding, a bonding tool, or the like. Therefore, the support member 41 rotates integrally with the second rotation member 26. The radial support portion 41a faces the end portion 32u1 of the first weight member 32J in the radial direction. There may be a gap or no gap between the radial support portion 41a and the end portion 32u1. The radial support portion 41a supports the first weight member 32J in the radial direction in a state where the radial support portion 41a and the end portion 32u1 are in contact with each other in the radial direction. Further, the radial support portion 41a supports the first weight member 32J so as to be rotatable around the rotation center Ax in a state where the radial support portion 41a and the end portion 32u1 are in radial contact with each other. That is, the radial support portion 41a functions as a radial bearing for the first weight member 32J. The axial support portion 41b is formed in an annular and plate shape around the rotation center Ax. The axial support portion 41b protrudes radially outward from the other axial direction of the radial support portion 41a, that is, from the right end in FIG. The axial direction support part 41b is located between the first extension part 32u and the second elastic member 33, and faces the first extension part 32u in the axial direction. There may be a gap or no gap between the axial support part 41b and the first extension part 32u.

Further, the axial support portion 41b supports the first weight member 32J so as to be rotatable around the rotation center Ax in a state where the axial support portion 41b and the first extension portion 32u are in contact with each other in the axial direction. That is, the axial direction support part 41b functions as a thrust bearing of the first weight member 32J. The support member 41 is made of a synthetic resin material, a metal material, or the like. The support member 41 may be constituted by a ball bearing, a roller bearing, or the like.

以上のように、本実施形態では、例えば、支持部材４１は、第二の回転部材２６に設けられ、第一の錘部材３２Ｊを第二の回転部材２６の径方向に支持する。よって、本実施形態によれば、例えば、支持部材４１によって、第一の錘部材３２Ｊの径方向への移動を抑制することができる。よって、例えば、第一の錘部材３２Ｊの偏心を抑制することができる。   As described above, in the present embodiment, for example, the support member 41 is provided on the second rotating member 26 and supports the first weight member 32J in the radial direction of the second rotating member 26. Therefore, according to the present embodiment, for example, the support member 41 can suppress the movement of the first weight member 32J in the radial direction. Therefore, for example, the eccentricity of the first weight member 32J can be suppressed.

また、本実施形態では、例えば、支持部材４１は、第一の錘部材３２Ｊを回転中心Ａｘ回りに回転可能に支持する軸受として機能する。よって、本実施形態によれば、例えば、支持部材４１とは別に軸受が設けられた場合に比べて、ダンパ装置１Ｍの製造に要する手間や費用が低減されやすい。   In the present embodiment, for example, the support member 41 functions as a bearing that supports the first weight member 32J so as to be rotatable about the rotation center Ax. Therefore, according to the present embodiment, for example, compared to a case where a bearing is provided separately from the support member 41, labor and cost required for manufacturing the damper device 1M are easily reduced.

また、本実施形態では、例えば、支持部材４１は、第一の錘部材３２Ｊの径方向の内側の端部３２ｕ１を支持する。よって、本実施形態によれば、例えば、支持部材が第一の錘部材の径方向の外側の端部を支持する構成に比べて、支持部材４１における第一の錘部材３２Ｊの支持位置と回転中心Ａｘとの間の距離を短くすることができる。よって、例えば、支持部材４１と第一の錘部材３２Ｊとの接触によるトルクを小さくすることができる。   In the present embodiment, for example, the support member 41 supports the radially inner end 32u1 of the first weight member 32J. Therefore, according to the present embodiment, for example, the support member 41 supports and rotates the first weight member 32J in the support member 41 as compared with the configuration in which the support member supports the radially outer end of the first weight member. The distance from the center Ax can be shortened. Therefore, for example, torque due to contact between the support member 41 and the first weight member 32J can be reduced.

また、本実施形態では、例えば、第一の錘部材３２Ｊは、第二の弾性部材３３と接続されたベース部３２ｔと、端部３２ｕ１を含みベース部３２ｔから第二の回転部材２６の径方向の内側に延びた第一の延部３２ｕと、を有する。よって、本実施形態によれば、例えば、支持部材４１と第一の錘部材３２Ｊとの接触によるトルクがより小さくなりやすい。   In the present embodiment, for example, the first weight member 32J includes a base portion 32t connected to the second elastic member 33 and an end portion 32u1, and the radial direction of the second rotating member 26 from the base portion 32t. And a first extension 32u extending inward. Therefore, according to the present embodiment, for example, torque due to contact between the support member 41 and the first weight member 32J is likely to be smaller.

また、本実施形態では、支持部材４１は、第二の弾性部材３３の径方向の中心よりも径方向の内側に位置されている。よって、本実施形態によれば、例えば、支持部材４１と第一の錘部材３２Ｊとの接触によるトルクがより小さくなりやすい。なお、本実施形態では、第一の錘部材３２Ｊのみが示されたが、不図示の第二の錘部材も第一の錘部材３２Ｊと略同様に構成されうる。この場合、不図示の第二の錘部材と第二の回転部材２６との間に、支持部材４１と略同様の支持部材が設けられうる。   In the present embodiment, the support member 41 is located on the inner side in the radial direction from the radial center of the second elastic member 33. Therefore, according to the present embodiment, for example, torque due to contact between the support member 41 and the first weight member 32J is likely to be smaller. In the present embodiment, only the first weight member 32J is shown, but a second weight member (not shown) can be configured in substantially the same manner as the first weight member 32J. In this case, a support member substantially similar to the support member 41 can be provided between the second weight member (not shown) and the second rotating member 26.
