Description

本発明は、直動変位に対応して反力を発生するマスダンパーに係る。特に、地震の態様の変化に対応できるマスダンパーに関する。 The present invention relates to a mass damper that generates a reaction force in response to a linear displacement. In particular, it relates to a mass damper that can respond to changes in the mode of an earthquake.

地震が発生すると、建物、構造物等の対象構造物が水平、垂直に揺すられる。
地震等による加速度レベルが大きいと、対象構造物が損傷をうけたり、対象構造物の中にあるものが予想を越えて加速度を受けたり、予想を超える変位をうけたりする。
そこで、基礎から対象構造物へ伝達する振動エネルギーを減少させて振動を免震する免震装置、または対象構造物が振動した際に振動エネルギーを吸収し振動レベルを小さくして振動を制振する制振装置として各種の構造の装置が試されている。
構造とその構造を構成する要素の諸元を適正に設定することにより、所望の免震性能や制振性能を発揮できる。 When an earthquake occurs, target structures such as buildings and structures are shaken horizontally and vertically.
If the acceleration level due to an earthquake or the like is large, the target structure may be damaged, the contents of the target structure may be accelerated more than expected, or the target structure may be displaced more than expected.
Therefore, a seismic isolation device that reduces the vibration energy transmitted from the foundation to the target structure to eliminate vibration, or absorbs vibration energy when the target structure vibrates and reduces the vibration level to suppress vibration. Devices with various structures are being tested as vibration damping devices.
By properly setting the structure and the specifications of the elements that make up the structure, the desired seismic isolation performance and vibration damping performance can be exhibited.

例えば、直動変位の変位方向に沿ってねじ送り方向を向けた雄ねじを設けられた直動軸と雄ねじに嵌めあう雌ねじを設けられた回転部材と回転部材を回転自在に支持するフレームで構成されるマスダンパーを用いる。
マスダンパーは、直動軸を所定の相対加速度で直動変位させたさいに作用する反力を直動変位の相対加速度で割った値であるみかけの慣性質量ｍｒとを持つ。 For example, it is composed of a linear motion shaft provided with a male screw whose screw feed direction is directed along the displacement direction of the linear displacement, a rotating member provided with a female screw that fits the male screw, and a frame that rotatably supports the rotating member. Use a mass damper.
The mass damper has an apparent inertial mass mr which is a value obtained by dividing the reaction force acting when the linear motion shaft is linearly displaced by a predetermined relative acceleration by the relative acceleration of the linear motion displacement.

例えば、直動変位の変位方向に沿ってねじ送り方向を向けた雄ねじを設けられた直動軸と雄ねじに嵌めあう雌ねじを設けられた回転部材と回転部材を回転自在に支持するフレームとフレームの内面と回転部材との隙間に封入された粘性流体とで構成される粘性マスダンパーを用いる。
粘性マスダンパーは、直動軸を所定の相対加速度で直動変位させたさいに作用する反力を直動変位の相対加速度で割った値であるみかけの慣性質量ｍｒと直動軸を一定の相対速度で直動変位させた際に作用する反力を相対速度で割った値に対応する減衰係数ｃとを持つ。 For example, a linear motion shaft provided with a male screw whose screw feed direction is directed along the displacement direction of the linear displacement, a rotating member provided with a female screw that fits the male screw, and a frame and a frame that rotatably support the rotating member. A viscous mass damper composed of a viscous fluid sealed in the gap between the inner surface and the rotating member is used.
The viscous mass damper has a constant apparent inertial mass mr and the linear motion axis, which is the value obtained by dividing the reaction force acting when the linear motion axis is linearly displaced at a predetermined relative acceleration by the relative acceleration of the linear motion displacement. It has a damping coefficient c corresponding to the value obtained by dividing the reaction force acting when the linear displacement is performed at the relative velocity by the relative velocity.

また、その粘性マスダンパーに弾性体を直列接続されたバネ付き粘性マスダンパーを用いる。
バネ付き粘性マスダンパーは、バネ要素を直動方向に相対距離だけ変位させた際に発生する反力を相対距離で割った値である弾性係数ｋｂと粘性マスダンパーの直動軸を直動方向に所定の相対加速度で直動させたさいに直動方向に作用する反力を相対加速度で割った値であるみかけの慣性質量ｍｒとに対応するダンパー固有振動数ωｒと粘性マスダンパーの直動軸を一定の相対速度で直動させた際に直動方向に作用する反力を相対速度で割った値に対応する減衰係数ｃとを持つ。 Further, a spring-loaded viscous mass damper in which an elastic body is connected in series to the viscous mass damper is used.
The viscous mass damper with a spring has an elastic coefficient kb, which is the value obtained by dividing the reaction force generated when the spring element is displaced in the linear motion direction by a relative distance, and the linear motion axis of the viscous mass damper in the linear motion direction. The damper natural frequency ωr and the linear motion of the viscous mass damper corresponding to the apparent inertial mass mr, which is the value obtained by dividing the reaction force acting in the linear motion direction by the relative acceleration when the linear motion is performed at a predetermined relative acceleration. It has a damping coefficient c corresponding to the value obtained by dividing the reaction force acting in the linear motion direction by the relative velocity when the axis is linearly moved at a constant relative velocity.

直動軸が直動変位すると回転部材が回転する。
回転部材の回転慣性能率に対応した回転反力が発生する。回転反力は雄ねじと雌ねじの作用で直動変位する方向の反力に変換される。
回転部材が回転すると回転部材とフレームとの隙間に封入した粘性流体に剪断力が生じ、その剪断力に対応した回転反力が発生する。回転反力は、雄ねじと雌ねじの作用で直動変位する方向の反力に変換される。
この慣性力と剪断力による反力は回転部材の質量と粘性流体の量に比較してみかけ上の大きな質量と大きなダンパーにより組み合わされた質量系としての動特性をもつ。
粘性マスダンパーと弾性体が直列接続されるので、見掛け上の大きな質量と大きなダンパーにより組み合わされたバネマス系としての振動特性をもつ。 When the linear motion shaft is linearly displaced, the rotating member rotates.
A rotational reaction force corresponding to the rotational moment of inertia of the rotating member is generated. The rotational reaction force is converted into a reaction force in the direction of linear displacement by the action of the male and female threads.
When the rotating member rotates, a shearing force is generated in the viscous fluid sealed in the gap between the rotating member and the frame, and a rotational reaction force corresponding to the shearing force is generated. The rotational reaction force is converted into a reaction force in the direction of linear displacement by the action of the male and female threads.
The reaction force due to this inertial force and shearing force has dynamic characteristics as a mass system combined with an apparently large mass and a large damper compared to the mass of the rotating member and the amount of viscous fluid.
Since the viscous mass damper and the elastic body are connected in series, it has vibration characteristics as a spring mass system combined with an apparently large mass and a large damper.

建造物の振動周期に同調して振動を抑制する伝達制限手段付き粘性マスダンパーが知られている。
粘性マスダンパーは質量要素と粘性要素を備える。
質量要素は加速度に依存して反力を発生する。大地震が発生した時、過大な反力により、ダンパー自身や接合部に損傷を与える可能性がある。伝達制限手段はこれらの損傷を抑制させるために慣性力を発揮する回転部材にトルクを伝達させないように備えられたもので、回転する部材と固定される部材との間の円周方向に複数個設置される。
伝達制限手段は、押圧パッドと皿ばねと調整ボルトとで構成される。例えば、押圧パッドはＰＴＦＥなどの摩擦材である。押圧パッドは皿ばねを介して調整ボルトで摩擦材に軸力を与えることで回転部材がすべりはじめるトルクまたはネジ軸方向の軸力を設定することができる。摩擦材が回転すべり変位に応じた摩擦抵抗を発揮するため、摩擦ダンパーの役割も期待できる。摩擦抵抗は軸力制限荷重に対応する。
この摩擦抵抗の設定は、建造物の振動抑制効果に大きな影響を与える。地震動の振動特性や入力レベルによって、軸力制限荷重を任意に変えることができることが望ましい。従来の構造では、一つの軸力制限荷重しか設定できず、様々な地震動特性に対して粘性マスダンパーの効果を十分に発揮できない。
一方で摩擦ダンパーとしても機能を発揮させた場合、大地震では摩擦材の発熱により軸力制限が安定的に発揮できない。
本願発明は、上記の点に着目し、構造物の振動抑制効果を保持させるために、様々な地震動の振動特性や入力レベルに応じて、摩擦材に与える軸力を任意に可変にすることができるマスダンパーを提供しようとする。 A viscous mass damper with a transmission limiting means that suppresses vibration in synchronization with the vibration cycle of a building is known.
The viscous mass damper has a mass element and a viscous element.
The mass element generates a reaction force depending on the acceleration. When a large earthquake occurs, excessive reaction force may damage the damper itself and joints. Transmission limiting means are provided so as not to transmit torque to a rotating member that exerts an inertial force in order to suppress these damages, and a plurality of transmission limiting means are provided in the circumferential direction between the rotating member and the fixed member. Will be installed.
The transmission limiting means includes a pressing pad, a disc spring, and an adjusting bolt. For example, the pressing pad is a friction material such as PTFE. The pressing pad can set the torque at which the rotating member starts to slide or the axial force in the screw axial direction by applying an axial force to the friction material with an adjusting bolt via a disc spring. Since the friction material exhibits frictional resistance according to the rotational slip displacement, it can be expected to play the role of a friction damper. The frictional resistance corresponds to the axial force limiting load.
The setting of this frictional resistance has a great influence on the vibration suppressing effect of the building. It is desirable that the axial force limiting load can be changed arbitrarily depending on the vibration characteristics of the seismic motion and the input level. In the conventional structure, only one axial force limiting load can be set, and the effect of the viscous mass damper cannot be sufficiently exerted on various seismic motion characteristics.
On the other hand, when the function is also exerted as a friction damper, the axial force limitation cannot be stably exerted due to the heat generation of the friction material in a large earthquake.
Focusing on the above points, the present invention can arbitrarily change the axial force applied to the friction material according to the vibration characteristics and input level of various seismic motions in order to maintain the vibration suppressing effect of the structure. We try to provide a mass damper that can be used.

It has an actuator that is supported by the member and presses the friction member against the first member with a predetermined pressing force, and a control device that controls the actuator.

上記本発明の構成により、直動軸は、直動変位の変位方向に沿ってねじ送り方向を向けた雄ねじを設けられる。回転部材は、前記雄ねじに嵌めあう雌ねじを設けられた部材である。フライホイール部材は、前記回転部材の回転に連動して回転できる部材である。

The rotating member is a member provided with a female screw that fits the male screw. The flywheel member is a member that can rotate in conjunction with the rotation of the rotating member.
The transmission limiting member is a member capable of limiting the torque that can be transmitted between the rotating member and the flywheel member. The frame rotatably supports the rotating member and the flywheel member. The friction member of the transmission limiting member comes into contact with the first member, which is one of the rotating member or the flywheel member, and generates a frictional force. The actuator of the transmission limiting member is supported by the second member, which is the other member of the rotating member or the flywheel member, and presses the friction member against the first member with a predetermined pressing force. The control device controls the actuator.
As a result, when the linear motion shaft moves relative to the direction of the linear motion displacement, the rotation of the rotating member is pressed against the actuator supported by the second member with a predetermined pressing force between the friction member and the first member. The flywheel member is transmitted to the flywheel member with a torque corresponding to the frictional force generated in the above, and the flywheel member rotates in response to the relative displacement of the linear motion shaft in the linear motion direction in response to the pressing force generated by the actuator. ..

A rotating member provided with a female screw fitted to a male screw provided on a linear motion shaft and the flywheel member are coupled via a transmission limiting member, rotatably supported by a frame, and controlled by a control device. Since the actuator presses the friction member against the first member with a predetermined pressing force, the rotation of the rotating member is supported by the second member when the linear motion shaft moves relative to the direction of the linear motion displacement. It is transmitted to the flywheel member with a torque corresponding to the frictional force generated between the friction member and the first member that is pressed against the actuator by a predetermined pressing force, and corresponds to the pressing force generated by the actuator. The flywheel member rotates in response to the relative displacement of the linear motion shaft in the linear motion direction.
Further, since the electric circuit applies a voltage to the pair of terminals of the piezoelectric element to expand or compress the piezoelectric element so that the friction member can be pressed against the first member, the pair of terminals of the piezoelectric element can be pressed. The piezoelectric element can be expanded or compressed in response to the voltage applied to the friction member to press the friction member against the first member.
Further, the electric circuit can apply a voltage to the pair of terminals of the piezoelectric element to extend or shorten the piezoelectric element to press the friction member against the first member via the compressed spring member. Therefore, the piezoelectric element can be expanded or compressed in response to the voltage applied to the pair of terminals of the piezoelectric element to push the spring member, and the spring member can press the friction member against the first member.
Further, since the control device changes the pressing force in response to a change in the maximum amplitude value of the acceleration generated on the foundation, the linear motion axis is linear in response to the change in the maximum amplitude value of the acceleration generated in the foundation. The flywheel member rotates in response to the relative displacement in the moving direction.
Further, the pressing force generated by the actuator is changed so as to increase as the maximum amplitude value of the acceleration generated on the foundation increases, and decreases as the maximum amplitude value of the acceleration generated on the foundation decreases. When the acceleration generated on the foundation is large, the pressing force is large and the apparent mass due to the rotation of the flywheel member is large, and when the acceleration generated on the foundation is small, the pressing force is small and the flywheel member The apparent mass due to rotation becomes smaller.
Further, the pressing force generated by the actuator is changed so as to increase as the maximum amplitude value of the acceleration generated on the foundation increases, and decreases as the maximum amplitude value of the acceleration generated on the foundation decreases. When the acceleration generated on the foundation is large, the pressing force is large and the apparent mass due to the rotation of the flywheel member is large, and when the acceleration generated on the foundation is small, the pressing force is small and the flywheel member The apparent mass due to rotation becomes smaller.
Further, since the actuator is adjusted so that the pressing force detected by the pressing force sensor matches the pressing force command value, the pressing force is applied even if the member expands due to the frictional heat generated by the pressing force. The pressing force command value can be maintained.
Further, since the extension or shortening of the piezoelectric element is controlled and the actuator is adjusted so that the pressing force matches the pressing force command value, even if the member expands due to frictional heat due to the pressing force. The pressing force can be maintained at the pressing force command value.
Further, since the pressing force generated by the actuator is adjusted so that the temperature of the contact portion of the friction member or the first member in contact with the friction member becomes equal to or lower than the temperature command value, the friction member Alternatively, overheating of the contact portion where the friction member of the first member comes into contact can be suppressed.
Further, the extension or shortening of the piezoelectric element is controlled to adjust the pressing force generated by the actuator, and the temperature of the contact portion of the friction member or the first member in contact with the friction member becomes equal to or lower than the temperature command value.

摩擦材の押付け力を可変にすることはダンパーの反力を可変にすることになり、様々な地震動に対して振動を制御することが可能になる。この可変機構は、電圧信号を制御するための電子制御ユニット（ＥＣＵ）と地震動の加速度を感知する加速度センサを備える。また、摩擦材の温度を関知する温度センサを備えていても良い。
制御方法は、加速度センサによって得られた地震動の加速度を逐次分析し、周期特性や速度レベルに応じて、逐次軸力を変化させても良い。軸力を安定させるため、温度センサによって得られた摩擦材の温度上昇による材料の膨張や皿ばねの軸力変動を抑制するため摩擦材の温度を監視してもよい。
電子制御ユニット（ＥＣＵ）の電源には、圧電素子の回生電源を使用してもよいし、ダンパー自身を特開２０１１−１０６５１９に開示されている発電ダンパーとし、このダンパーで蓄電した回生電源を利用してもよい。なお、皿ばねや調整ばねは同様の効果が得られる範囲で、圧電材を複数重ねた圧電アクチエータのような構造としてもよい。
圧電信号に応じて摩擦材に与える軸力を可変にできる材料を組み合わせた点、この材料は円周方向に備えられているため、ボールねじの変換効率（増幅機構）により、皿ばねに与える変形は小さくても大きな軸方向の力を得られる。
例えば、アクチアータとして、圧電素子や圧電ゴムといった材料を使用し、これらの材料の特性を変化させるための電子制御ユニット（ＥＣＵ）、および地震動の振動成分や摩擦材の温度を感知するセンサを用いた。 A piezoelectric element that can change its own length according to the voltage signal is set between the disc spring and the adjusting screw, and the deformation given to the disc spring is arbitrarily adjusted to apply a pressing force to the friction material. This made it possible to change the pressing force.
By making the pressing force of the friction material variable, the reaction force of the damper becomes variable, and it becomes possible to control the vibration against various seismic motions. This variable mechanism includes an electronic control unit (ECU) for controlling a voltage signal and an acceleration sensor for detecting the acceleration of seismic motion. Further, a temperature sensor for detecting the temperature of the friction material may be provided.
As a control method, the acceleration of the seismic motion obtained by the acceleration sensor may be sequentially analyzed, and the axial force may be sequentially changed according to the periodic characteristics and the velocity level. In order to stabilize the axial force, the temperature of the friction material may be monitored in order to suppress the expansion of the material and the fluctuation of the axial force of the disc spring due to the temperature rise of the friction material obtained by the temperature sensor.
A regenerative power source of a piezoelectric element may be used as a power source of the electronic control unit (ECU), or the damper itself is a power generation damper disclosed in Japanese Patent Application Laid-Open No. 2011-106519, and the regenerative power source stored by this damper is used. You may. The disc spring and the adjusting spring may have a structure such as a piezoelectric actuator in which a plurality of piezoelectric materials are stacked, as long as the same effect can be obtained.

Since this material is provided in the circumferential direction, the deformation given to the disc spring due to the conversion efficiency (amplification mechanism) of the ball screw. Can obtain a large axial force even if it is small.
For example, a material such as a piezoelectric element or a piezoelectric rubber was used as an actiator, and an electronic control unit (ECU) for changing the characteristics of these materials, and a sensor for detecting the vibration component of seismic motion and the temperature of the friction material were used. ..

また、電気回路１６３ａが圧電素子１６２ａの一対の端子に電圧を印加して圧電素子１６２ａを伸長または短縮させて与圧縮されたバネ部材１６２ｂを介して摩擦部材１６１を回転部材１２０に押付けできる様にしたので、圧電素子１６２ａの一対の端子に印加される電圧に対応して圧電素子１６２ａを伸長または圧縮させてバネ部材１６２ｂを押し、バネ部材１６２ｂが摩擦部材１６１を回転部材１２０に押付けできる。
また、制御装置１６３が押付け力を基礎に生ずる加速度の最大振幅値の変化に対応して変化させる様にしたので、基礎に生ずる加速度の最大振幅値の変化に対応して直動軸１１０の直動方向の相対変位に対応してフライホイール部材１３０が回転する。
また、アクチエータ１６２の発生する押付け力を基礎に生ずる加速度の最大振幅値が大きくなるのに対応して大きくなる様に変化させ、基礎に生ずる加速度の最大振幅値が小さくなるのに対応して小さくなる様に変化させる様にしたので、基礎に生ずる加速度が大きいときに押し付け力が大きくフライホイール部材１３０の回転による見かけの質量が大きくなり抵抗力が大きくなり、基礎に生ずる加速度が小さいときに押し付け力が小さくフライホイール部材１３０の回転による見かけの質量が小さくなり抵抗力が小さくなる。
また、アクチエータ１６２の発生する押付け力を基礎に生ずる加速度の最大振幅値が大きくなるのに対応して大きくなる様に変化させ、基礎に生ずる加速度の最大振幅値が小さくなるのに対応して小さくなる様に変化させる様にしたので、基礎に生ずる加速度が大きいときに押し付け力が大きくフライホイール部材の回転による見かけの質量が大きく抵抗力が大きくなり、基礎に生ずる加速度が小さいときに押し付け力が小さくフライホイール部材の回転による見かけの質量が小さくなり抵抗力が小さくなる。
また、アクチエータ１６２を調整して押付け力センサ１６６ａの検知する押付け力を押付け力指令値に一致する様にする様にしたので、押し付け力による摩擦熱により部材が膨張しても押し付け力を押付け力指令値に維持できる。

また、アクチエータ１６２の発生する押付け力を調整し摩擦部材１６１または回転部材１２０の摩擦部材１６１が接触する接触部位の温度を温度指令値以下になる様にする様にしたので、摩擦部材１６１または回転部材１２０の摩擦部材１６１が接触する接触部位のオーバーヒートを抑制できる。
また、圧電素子１６２ａの伸長または短縮を制御してアクチエータ１６２の発生する押付け力を調整し摩擦部材１６１または回転部材１２０の摩擦部材１６１が接触する接触部位の温度を温度指令値以下になる様にする様にしたので、摩擦部材１６１または回転部材１２０の摩擦部材１６１が接触する接触部位のオーバーヒートを抑制できる。 Further, as described above, the mass damper according to the present invention has the following effects depending on its configuration.
A rotating member 120 provided with a female screw fitted to a male screw provided on the linear motion shaft 110 and a flywheel member 130 are coupled via a transmission limiting member 160 and rotatably supported by a frame 140 to be supported by a control device. Since the actuator 162 controlled by 163 presses the friction member 161 against the rotating member 120 with a predetermined pressing force, the rotating member 120 rotates when the linear motion shaft 110 moves relative to the direction of the linear motion displacement. Is transmitted to the flywheel member 130 with a torque corresponding to the frictional force generated between the friction member 161 and the rotating member 120, which is pressed against the activator 162 supported by the flywheel member 130 with a predetermined pressing force, and is transmitted to the activator 162. The flywheel member 130 rotates in response to the relative displacement of the linear motion shaft 110 in the linear motion direction in response to the pressing force generated.
Further, since the electric circuit 163a applies a voltage to the pair of terminals of the piezoelectric element 162a to expand or compress the piezoelectric element 162a so that the friction member 161 can be pressed against the rotating member 120, the pair of terminals of the piezoelectric element 162a can be pressed. The piezoelectric element 162a can be expanded or compressed in response to the voltage applied to the friction member 161 to be pressed against the rotating member 120.
Further, the electric circuit 163a applies a voltage to the pair of terminals of the piezoelectric element 162a to extend or shorten the piezoelectric element 162a so that the friction member 161 can be pressed against the rotating member 120 via the compressed spring member 162b. Therefore, the piezoelectric element 162a can be expanded or compressed in response to the voltage applied to the pair of terminals of the piezoelectric element 162a to push the spring member 162b, and the spring member 162b can press the friction member 161 against the rotating member 120.
Further, since the control device 163 changes the pressing force in response to the change in the maximum amplitude value of the acceleration generated on the foundation, the direct motion shaft 110 is changed in response to the change in the maximum amplitude value of the acceleration generated in the foundation. The flywheel member 130 rotates in response to the relative displacement in the moving direction.
Further, the pressing force generated by the actuator 162 is changed so as to increase as the maximum amplitude value of the acceleration generated on the foundation increases, and decreases as the maximum amplitude value of the acceleration generated on the foundation decreases. Therefore, when the acceleration generated on the foundation is large, the pressing force is large, the apparent mass due to the rotation of the flywheel member 130 is large, the resistance force is large, and when the acceleration generated on the foundation is small, the pressing force is large. The force is small, the apparent mass due to the rotation of the flywheel member 130 is small, and the resistance is small.
Further, the pressing force generated by the actuator 162 is changed so as to increase as the maximum amplitude value of the acceleration generated on the foundation increases, and decreases as the maximum amplitude value of the acceleration generated on the foundation decreases. Therefore, when the acceleration generated on the foundation is large, the pressing force is large, the apparent mass due to the rotation of the flywheel member is large, and the resistance force is large, and when the acceleration generated on the foundation is small, the pressing force is large. It is small and the apparent mass due to the rotation of the flywheel member becomes small, and the resistance force becomes small.
Further, since the actuator 162 is adjusted so that the pressing force detected by the pressing force sensor 166a matches the pressing force command value, the pressing force is applied even if the member expands due to the frictional heat generated by the pressing force. It can be maintained at the command value.
Further, since the extension or shortening of the piezoelectric element 162a is controlled and the actuator 162 is adjusted so that the pressing force matches the pressing force command value, the pressing force is pressed even if the member expands due to the frictional heat generated by the pressing force. The force can be maintained at the pressing force command value.
Further, since the pressing force generated by the actuator 162 is adjusted so that the temperature of the contact portion where the friction member 161 of the friction member 161 or the friction member 120 of the rotary member 120 comes into contact is equal to or lower than the temperature command value, the friction member 161 or the rotation It is possible to suppress overheating of the contact portion where the friction member 161 of the member 120 comes into contact.
Further, the extension or shortening of the piezoelectric element 162a is controlled to adjust the pressing force generated by the actuator 162 so that the temperature of the contact portion with which the friction member 161 of the friction member 161 or the friction member 120 of the rotating member 120 comes into contact becomes equal to or lower than the temperature command value. Therefore, overheating of the contact portion where the friction member 161 or the friction member 161 of the rotating member 120 comes into contact can be suppressed.
