Description

配線保護構造、および空気調和機の室内ユニットWiring protection structure and indoor unit of air conditioner
　本発明の実施形態は、回動機構と回動機構に対して変動しない非回動機構との間を繋ぐ配線を保護する構造（配線保護構造）、および該配線保護構造を備えた空気調和機の室内ユニットに関する。 An embodiment of the present invention is a structure for protecting wiring (wiring protection structure) connecting a rotating mechanism and a non-rotating mechanism that does not fluctuate with respect to the rotating mechanism, and an air conditioner provided with the wiring protection structure. Regarding the indoor unit of.
　一般に、空気調和機の室内ユニットは、空気の吸込口と、空気の吹出口と、吹出口の外郭を覆う吹出口カバーと、熱交換器と、吸込口から熱交換器を経て吹出口に至る気流を発生させるファンと、熱交換器を収容する筐体とを備えている。吹出口には、熱交換器で温調されて空調対象の室内空間に吹き出される気流（以下、吹出風という）を偏向させるルーバーが設けられている。室内空間に吹出風を行き渡らせ、室内温度を効率よく調整するため、ルーバーは、複数枚の風向板を有して構成される。これらの風向板は、駆動機構で回動軸まわりに回動して偏向可能とされる。 In general, the indoor unit of an air conditioner includes an air inlet, an air outlet, an outlet cover that covers the outer shell of the outlet, a heat exchanger, and a heat exchanger from the inlet to the outlet. It is equipped with a fan that generates airflow and a housing that houses a heat exchanger. The air outlet is provided with a louver that deflects the airflow (hereinafter referred to as the airflow) that is temperature-controlled by a heat exchanger and blown out into the indoor space to be air-conditioned. The louver is configured to have a plurality of wind direction plates in order to spread the blown air through the indoor space and efficiently adjust the indoor temperature. These wind direction plates can be deflected by rotating around a rotation axis by a drive mechanism.
　風向板の偏向に加えて、風向板およびその回動軸を吹出口の中心軸を中心に周方向へ回動させて変位させることで、室内空間により満遍なく吹出風を行き渡らせ、室内温度をさらに効率よく調整することが可能である。例えば、吹出口および風向板を含む回動ユニットを室内ユニットの筐体や吹出口カバーに対して回動可能とした場合、風向板の駆動機構に接続される配線は、回動ユニットと吹出口カバーとの間の空間に配され、筐体と回動ユニットとの間を繋ぐ。配線は、例えばモータのリード線、制御基板の信号線や電源線などであり、その本数は問わない。 In addition to the deflection of the wind direction plate, the wind direction plate and its rotation axis are displaced by rotating them in the circumferential direction around the central axis of the air outlet, so that the blown air is evenly distributed in the indoor space and the indoor temperature is further increased. It is possible to adjust efficiently. For example, when the rotating unit including the air outlet and the air outlet is rotatable with respect to the housing of the indoor unit and the air outlet cover, the wiring connected to the drive mechanism of the air outlet is the rotating unit and the air outlet. It is arranged in the space between the cover and connects the housing and the rotating unit. The wiring is, for example, a lead wire of a motor, a signal line of a control board, a power supply line, or the like, and the number of wires does not matter.
　その一方で、回動ユニットは吹出口カバーに対して回動する回動機構であり、吹出口カバーは筐体に取り付けられて変動しない部材（回動機構に対する非回動機構の一構成部材）である。このため、回動ユニットの回動時に回動ユニットと吹出口カバーとの間で配線が暴れ、本来の配線位置から外れてしまうおそれがある。 On the other hand, the rotating unit is a rotating mechanism that rotates with respect to the air outlet cover, and the air outlet cover is a member that is attached to the housing and does not fluctuate (a component of the non-rotating mechanism with respect to the rotating mechanism). Is. Therefore, when the rotating unit is rotated, the wiring between the rotating unit and the air outlet cover may be violent, and the wiring may deviate from the original wiring position.

　本発明が解決しようとする課題は、回動機構と非回動機構の間での配線暴れを抑制し、これらの部材間を繋ぐ配線の保護を図る配線保護構造、および該配線保護構造を備えた空気調和機の室内ユニットを提供することにある。 The problem to be solved by the present invention is to provide a wiring protection structure for suppressing wiring runaway between a rotating mechanism and a non-rotating mechanism and protecting the wiring connecting these members, and the wiring protection structure. The purpose is to provide indoor units for air conditioners.
　一実施形態に係る空気調和機の室内ユニットにおける配線保護構造は、所定の中心軸を中心として回動する回動機構と、前記回動機構に対して変動しない非回動機構との間を繋ぐ配線を保護し、前記配線を内部に通す保護部材を備える。前記保護部材は、配線部と折返し部とを備える。前記配線部は、前記配線の差渡し寸法よりも大寸の差渡し寸法に設定された前記配線の配線空間を規定する。前記折返し部は、前記配線部の折返し位置を前記回動機構の回動方向に変位可能に前記配線部を折り返す。 The wiring protection structure in the indoor unit of the air conditioner according to the embodiment connects between a rotating mechanism that rotates about a predetermined central axis and a non-rotating mechanism that does not change with respect to the rotating mechanism. A protective member that protects the wiring and allows the wiring to pass through the inside is provided. The protective member includes a wiring portion and a folded portion. The wiring portion defines a wiring space of the wiring set to a distribution dimension larger than the distribution dimension of the wiring. The folded-back portion folds back the wiring portion so that the folded-back position of the wiring portion can be displaced in the rotation direction of the rotating mechanism.

　前面板２０は、Ｙ方向において熱交換器６と重なる開口２９を有している。吹出口カバー４０の内側には、開口２９を通じて熱交換器６と対向するファン９が配置されている。ファン９は、熱交換器６で熱交換により温調された空気の気流を発生させる。ファン９は、例えば軸流ファンであり、ファンモータ９０と、ファンモータ９０によって軸ＡＸを中心に回転する複数の羽根９１とを備えている。本実施形態において、軸ＡＸはＹ方向と平行である。 The front plate 20 has an opening 29 that overlaps with the heat exchanger 6 in the Y direction. Inside the air outlet cover 40, a fan 9 facing the heat exchanger 6 through the opening 29 is arranged. The fan 9 generates an air flow of air whose temperature is controlled by heat exchange in the heat exchanger 6. The fan 9 is, for example, an axial fan, and includes a fan motor 90 and a plurality of blades 91 rotated about a shaft AX by the fan motor 90. In this embodiment, the axis AX is parallel to the Y direction.
　ファン９は、軸ＡＸと同軸の第１筒部材９２の内部に配置されている。第１筒部材９２は、筐体２に固定され、筐体２の外側かつ吹出口カバー４０の内側において開口２９を囲っている。第１筒部材９２の外周面の少なくとも一部は、断熱材９３によって覆われている。 The fan 9 is arranged inside the first cylinder member 92 coaxial with the shaft AX. The first cylinder member 92 is fixed to the housing 2 and surrounds the opening 29 on the outside of the housing 2 and inside the air outlet cover 40. At least a part of the outer peripheral surface of the first cylinder member 92 is covered with the heat insulating material 93.
　ルーバー５は、軸ＡＸと同軸の第２筒部材３１の端部に配置されている。ルーバー５の風向板５１，５２，５３は、例えばモータ３４を含む駆動機構（以下、ルーバー駆動機構という）３３によって回動される。 The louver 5 is arranged at the end of the second cylinder member 31 coaxial with the shaft AX. The wind direction plates 51, 52, and 53 of the louver 5 are rotated by, for example, a drive mechanism (hereinafter, referred to as a louver drive mechanism) 33 including a motor 34.
　第２筒部材３１の外周面３１ａの少なくとも一部は、断熱材３２によって覆われている。吹出口３は、第２筒部材３１の先端側の開口に相当する。図２および図３に示す例において、吹出口３の中心は軸ＡＸ上にある（吹出口３の中心軸と軸ＡＸが一致している）。 At least a part of the outer peripheral surface 31a of the second cylinder member 31 is covered with the heat insulating material 32. The air outlet 3 corresponds to an opening on the tip end side of the second cylinder member 31. In the examples shown in FIGS. 2 and 3, the center of the outlet 3 is on the axis AX (the central axis of the outlet 3 and the axis AX coincide with each other).
　図３および図４に示すように、第２筒部材３１の外周面３１ａには、ルーバー駆動機構３３が設けられている。ルーバー駆動機構３３は、モータ３４の駆動力により風向板５１，５２，５３の角度を変更するためのギアなどを含み、風向板５１，５２，５３を所定の傾きに回動させる。モータ３４は、所定の配線（モータ用リード線）で制御基板８０と接続されている。 As shown in FIGS. 3 and 4, a louver drive mechanism 33 is provided on the outer peripheral surface 31a of the second cylinder member 31. The louver drive mechanism 33 includes a gear for changing the angle of the wind direction plates 51, 52, 53 by the driving force of the motor 34, and rotates the wind direction plates 51, 52, 53 to a predetermined inclination. The motor 34 is connected to the control board 80 by a predetermined wiring (motor lead wire).
　ルーバー５、第２筒部材３１、断熱材３２、ルーバー駆動機構３３およびモータ３４は、回動ユニット３０を構成する。回動ユニット３０は、保持部材１０により軸ＡＸを中心として回動可能に保持されている。本実施形態において、軸ＡＸは、回動ユニット３０が回動する際の中心軸となっている。回動ユニット３０は、軸ＡＸを中心に１８０°の範囲内を回動可能域として回動する。回動可能域は、風向板５１，５２，５２の回動軸が水平（Ｘ－Ｙ平面と平行）となるように回動ユニット３０が位置した状態（図４に示す状態。以下、基準状態という）から、軸ＡＸを中心に１８０°の範囲内である。すなわち、基準状態から天地が逆転する範囲内で回動ユニット３０は回動する。ただし、回動可能域はこの範囲に限定されない。 The louver 5, the second cylinder member 31, the heat insulating material 32, the louver drive mechanism 33, and the motor 34 constitute the rotation unit 30. The rotating unit 30 is rotatably held around the shaft AX by the holding member 10. In the present embodiment, the shaft AX is the central shaft when the rotating unit 30 rotates. The rotating unit 30 rotates around the axis AX as a rotatable region within a range of 180 °. The rotatable region is a state in which the rotating unit 30 is positioned so that the rotation axes of the wind direction plates 51, 52, 52 are horizontal (parallel to the XY plane) (the state shown in FIG. 4, hereinafter, the reference state). It is within the range of 180 ° around the axis AX. That is, the rotating unit 30 rotates within a range in which the top and bottom are reversed from the reference state. However, the rotatable range is not limited to this range.
　具体的には、保持部材１０は、第２筒部材３１を第１筒部材９２に対して回動可能に、両者を接続している。保持部材１０は、モータ１１を含む。モータ１１は、例えば第２筒部材３１の端部に設けられたギアを、回転軸のギアに噛み合わせて軸ＡＸを中心とした円周方向に送る。これにより、第２筒部材３１が第１筒部材９２に対して回動する。第２筒部材３１は、手動で回動可能であってもよい。この場合、例えば軸ＡＸを中心とする円周方向に等間隔で三つの歯車を配置してギアに噛合させることで、第２筒部材３１を第１筒部材９２に対して回動可能に支持すればよい。回動ユニット３０を回動させる際には、突起３１１をつまんで、軸ＡＸを中心として周方向へ所望量だけ回動ユニット３０を回動させる。突起３１１は、第２筒部材３１の吹出口３の周縁に設けられて回動ユニット３０を回動させる力が作用される入力部であり、取っ手として機能する。 Specifically, the holding member 10 connects the second cylinder member 31 to the first cylinder member 92 so as to be rotatable. The holding member 10 includes a motor 11. For example, the motor 11 meshes the gear provided at the end of the second cylinder member 31 with the gear of the rotating shaft and sends the gear in the circumferential direction around the shaft AX. As a result, the second cylinder member 31 rotates with respect to the first cylinder member 92. The second tubular member 31 may be manually rotatable. In this case, for example, by arranging three gears at equal intervals in the circumferential direction around the shaft AX and engaging the gears, the second cylinder member 31 is rotatably supported with respect to the first cylinder member 92. do it. When rotating the rotating unit 30, the protrusion 311 is pinched and the rotating unit 30 is rotated about a shaft AX by a desired amount in the circumferential direction. The protrusion 311 is an input portion provided on the peripheral edge of the air outlet 3 of the second tubular member 31 and on which a force for rotating the rotating unit 30 is applied, and functions as a handle.
　第１筒部材９２および第２筒部材３１は、風路ＡＤを構成する。風路ＡＤは、熱交換器６で熱交換（温調）された空気がファン９の回転により気流となって通過する流路である。風路ＡＤの中心軸は、軸ＡＸと一致している。風路ＡＤにおいて、ファン９とルーバー５の間には整流板９４が配置されている。整流板９４は、第１筒部材９２によって支持され、ファン９によって発生した直後の乱れた気流を軸ＡＸと略平行に整える。整流板９４は、例えば六角形の多数の開口が配列されたハニカム構造を有しているが、この例に限られない。第１筒部材９２、第２筒部材３１、および整流板９４は、吹出口ユニット４の構成部材に含まれる。 The first cylinder member 92 and the second cylinder member 31 constitute an air passage AD. The air passage AD is a flow path through which the air heat-exchanged (temperature controlled) by the heat exchanger 6 passes as an air flow due to the rotation of the fan 9. The central axis of the air passage AD coincides with the axis AX. In the air passage AD, a straightening vane 94 is arranged between the fan 9 and the louver 5. The straightening vane 94 is supported by the first cylinder member 92, and arranges the turbulent airflow immediately after being generated by the fan 9 substantially parallel to the shaft AX. The straightening vane 94 has, for example, a honeycomb structure in which a large number of hexagonal openings are arranged, but the present invention is not limited to this example. The first cylinder member 92, the second cylinder member 31, and the straightening vane 94 are included in the constituent members of the outlet unit 4.
　ファン９が回転すると、吸込口２７、熱交換器６、整流板９４および吹出口３を順に通る気流が発生する。冷房運転時には熱交換器６が蒸発器として機能し、吸込口２７から吸い込まれた空気が冷やされる。暖房運転時には熱交換器６が凝縮器として機能し、吸込口２７から吸い込まれた空気が暖められる。温調された気流は、整流板９４で整流され、ルーバー５の風向板５１，５２，５３の角度に応じた方向へ吹出口３から室内空間に吹き出される。 When the fan 9 rotates, an air flow that passes through the suction port 27, the heat exchanger 6, the rectifying plate 94, and the air outlet 3 in this order is generated. During the cooling operation, the heat exchanger 6 functions as an evaporator, and the air sucked from the suction port 27 is cooled. During the heating operation, the heat exchanger 6 functions as a condenser to warm the air sucked from the suction port 27. The temperature-controlled airflow is rectified by the rectifying plate 94 and blown out from the outlet 3 into the indoor space in the direction corresponding to the angle of the wind direction plates 51, 52, 53 of the louver 5.
　制御部８は、外部から入力される情報や室内ユニット１が備える温度センサによって検出される吸込温度および吹出温度等に基づいてファン９の回転数を制御する。また、制御部８は、外部から入力される風向きの設定情報に基づいて保持部材１０やルーバー５を制御する。保持部材１０により回動ユニット３０を回動させ、かつルーバー５の風向板５１，５２，５３の角度を変更することで、様々な方向への送風が可能となる。 The control unit 8 controls the rotation speed of the fan 9 based on the information input from the outside, the suction temperature and the blowout temperature detected by the temperature sensor included in the indoor unit 1. Further, the control unit 8 controls the holding member 10 and the louver 5 based on the wind direction setting information input from the outside. By rotating the rotating unit 30 by the holding member 10 and changing the angles of the wind direction plates 51, 52, 53 of the louver 5, it is possible to blow air in various directions.
　続いて、回動ユニット３０と保持部材１０との間を繋ぐ配線を保護する配線保護構造について説明する。室内ユニット１において、回動ユニット３０は、軸ＡＸを中心として回動する回動機構である。保持部材１０は、第１筒部材９２を介して筐体２に固定されており、回動ユニット３０に対して変動しない非回動機構の構成部材の一つである。モータ３４と制御基板８０とを接続するリード線１ａ（図６参照）は、回動ユニット３０と保持部材１０との間を繋ぐ配線である。 Subsequently, a wiring protection structure for protecting the wiring connecting the rotating unit 30 and the holding member 10 will be described. In the indoor unit 1, the rotating unit 30 is a rotating mechanism that rotates around the shaft AX. The holding member 10 is fixed to the housing 2 via the first cylinder member 92, and is one of the constituent members of the non-rotating mechanism that does not fluctuate with respect to the rotating unit 30. The lead wire 1a (see FIG. 6) that connects the motor 34 and the control board 80 is a wiring that connects the rotating unit 30 and the holding member 10.
　図５には、図４の一部を拡大して配線保護構造１００を概略的に示す。配線保護構造１００は、リード線１ａを内部に通して保護する保護部材１０１と、保護部材１０１を保持するガイド部材１０２とを備えている。　
　保護部材１０１は、リード線１ａの配線経路に沿って一端から他端まで連続する部材であり、配線部１ｂと折返し部１ｃを有している。図６には、保護部材１０１を概略的に示す。図６に示す例では、保護部材１０１はコイルスプリング（つるまきばね）１０３とされている。コイルスプリング１０３は、線材、例えば金属線３００を巻回して形成されて一端１０３ａから他端１０３ｂまで螺旋状に連続し、屈曲や伸縮などの弾性変形が可能とされている。金属線３００は、螺旋状に巻回された内部空間内に配線されたリード線１ａを回動ユニット３０の回動時に保護可能な強度（剛性）と耐久性を有する。かかる強度（剛性）と耐久性を有していれば、コイルスプリング１０３の線材は、樹脂製などであってもよい。 FIG. 5 schematically shows the wiring protection structure 100 by enlarging a part of FIG. The wiring protection structure 100 includes a protective member 101 that protects the lead wire 1a through the inside, and a guide member 102 that holds the protective member 101.
The protective member 101 is a member that is continuous from one end to the other end along the wiring path of the lead wire 1a, and has a wiring portion 1b and a folded portion 1c. FIG. 6 schematically shows the protective member 101. In the example shown in FIG. 6, the protective member 101 is a coil spring (coil spring) 103. The coil spring 103 is formed by winding a wire, for example, a metal wire 300, and continues spirally from one end 103a to the other end 103b, and is capable of elastic deformation such as bending and expansion and contraction. The metal wire 300 has strength (rigidity) and durability that can protect the lead wire 1a wired in the spirally wound internal space when the rotating unit 30 rotates. The wire rod of the coil spring 103 may be made of resin or the like as long as it has such strength (rigidity) and durability.
　配線部１ｂは、保護部材１０１において配線が通る空間（配線空間）を規定する部分である。コイルスプリング１０３では、金属線３００が螺旋状に巻回されて一連の内部空間を形成する部分、端的には螺旋状に巻回された金属線３００が配線部１ｂに相当する。リード線１ａは、配線部１ｂ、つまり螺旋状に巻回された金属線３００が規定する内部空間（配線空間）を通して配線される。したがって、コイルスプリング１０３が弾性変形すると、これに応じて配線部１ｂに配線されたリード線１ａも同等の形態に変化する。具体的には、リード線１ａの折返し位置が変化する。 The wiring portion 1b is a portion of the protective member 101 that defines a space (wiring space) through which wiring passes. In the coil spring 103, a portion in which the metal wire 300 is spirally wound to form a series of internal spaces, in short, the spirally wound metal wire 300 corresponds to the wiring portion 1b. The lead wire 1a is wired through the wiring portion 1b, that is, the internal space (wiring space) defined by the spirally wound metal wire 300. Therefore, when the coil spring 103 is elastically deformed, the lead wire 1a wired to the wiring portion 1b also changes to the same form accordingly. Specifically, the folding position of the lead wire 1a changes.
　配線部１ｂは、リード線１ａの差渡し寸法（一例として外径）よりも大寸の差渡し寸法（一例として内径）で内部空間を規定する。換言すれば、コイルスプリング１０３は、配線部１ｂを通るリード線１ａと、配線部１ｂに相当する螺旋状に巻回する金属線３００との間に所定の空隙（遊び）を有している。したがって、配線部１ｂの配線空間に配線されたリード線１ａは、金属線３００と密着することなく、配線空間内で相対的に変位可能な状態となっている。 The wiring portion 1b defines the internal space with a larger transfer dimension (inner diameter as an example) than the transfer dimension (outer diameter as an example) of the lead wire 1a. In other words, the coil spring 103 has a predetermined gap (play) between the lead wire 1a passing through the wiring portion 1b and the metal wire 300 spirally wound corresponding to the wiring portion 1b. Therefore, the lead wire 1a wired in the wiring space of the wiring portion 1b is in a state of being relatively displaceable in the wiring space without being in close contact with the metal wire 300.
　折返し部１ｃは、コイルスプリング１０３において配線部１ｂが屈曲して折り返される部分である。リード線１ａは、折返し部１ｃで折り返されて配線部１ｂの内部空間に配線される。折返し部１ｃは、配線部１ｂの折返し位置を回動ユニット３０の回動方向に変位可能に配線部１ｂを折り返す。回動ユニット３０の回動方向は、吹出口カバー４０に対して回動ユニット３０が回動する方向であり、軸ＡＸを中心とした円周方向に相当する方向である（以下、単に回動方向という）。 The folded-back portion 1c is a portion where the wiring portion 1b is bent and folded back in the coil spring 103. The lead wire 1a is folded back at the folded-back portion 1c and wired in the internal space of the wiring portion 1b. The folded-back portion 1c folds back the wiring portion 1b so that the folded-back position of the wiring portion 1b can be displaced in the rotation direction of the rotating unit 30. The rotation direction of the rotation unit 30 is the direction in which the rotation unit 30 rotates with respect to the outlet cover 40, and is the direction corresponding to the circumferential direction about the axis AX (hereinafter, simply rotates). Direction).
　本実施形態では、金属線３００が弾性変形することで、折返し部１ｃは配線部１ｂの折返し位置を回動方向に変位させる。折返し部１ｃは、コイルスプリング１０３（端的には配線部１ｂ）の一端１０３ａよりも手前の位置と、他端１０３ｂの手前よりも手前の位置との間で、配線部１ｂの折り返し位置を変位させる。換言すれば、配線部１ｂは、回動ユニット３０の回動距離（回動可能域）の起点で一端１０３ａが折返し部１ｃよりも回動方向の手前に位置し、該回動距離の終点で他端１０３ｂが折返し部１ｃよりも回動方向の手前に位置する長さを有している。 In the present embodiment, the metal wire 300 is elastically deformed, so that the folded-back portion 1c displaces the folded-back position of the wiring portion 1b in the rotation direction. The folded-back portion 1c displaces the folded-back position of the wiring portion 1b between a position in front of one end 103a of the coil spring 103 (in short, a wiring portion 1b) and a position in front of the other end 103b. .. In other words, in the wiring portion 1b, one end 103a is located in front of the folded-back portion 1c in the rotation direction at the starting point of the rotation distance (rotatable range) of the rotation unit 30, and at the end point of the rotation distance. The other end 103b has a length located in front of the folded-back portion 1c in the rotation direction.
　ガイド部材１０２は、配線部１ｂを保持するとともに、折返し部１ｃの変位方向、換言すれば配線部１ｂの折返し位置を規定する。すなわち、配線部１ｂは、ガイド部材１０２が存在する範囲内でその姿勢が保持され、折返し位置が規定される。折返し部１ｃの変位方向は、回動方向とほぼ一致している。本実施形態において、ガイド部材１０２は、回動ユニット３０と保持部材１０にそれぞれ対をなして備えられている。 The guide member 102 holds the wiring portion 1b and defines the displacement direction of the folded-back portion 1c, in other words, the folded-back position of the wiring portion 1b.

The fixed side guide member 2b fixes the other end 103b of the wiring portion 1b.
　図７には、可動側ガイド部材２ａの概略的な構成を示す。図２、図５および図７に示すように、可動側ガイド部材２ａは、回動方向に沿った円弧状の部材であり、第２筒部材３１の外周を覆う断熱材３２の外周側に設けられている。図４および図５に示す例では、可動側ガイド部材２ａは第２筒部材３１のほぼ上半分に亘って配置されている。可動側ガイド部材２ａは、保持面２１ａおよび保持壁２２ａ，２３ａに沿って配線部１ｂ（端的には、コイルスプリング１０３）を保持する。保持面２１ａは、螺旋状に巻回する金属線３００の螺旋の曲率とほぼ同等の曲率で凹状に湾曲する湾曲面とされている。保持壁２２ａは、保持面２１ａの内周縁から起立し、保持壁２３ａは、保持面２１ａの外周縁から起立して保持壁２２ａと対向している。保持壁２２ａ，２３ａの周面は、平坦面であるが、螺旋状に巻回する金属線３００の螺旋の曲率とほぼ同等の曲率で凹状に湾曲していてもよい。可動側ガイド部材２ａにおいて、保持面２１ａと保持壁２２ａ，２３ａで囲まれた空間は、配線部１ｂの保持空間を規定する。保持空間の一部（固定側ガイド部材２ｂとの対向部であり、以下、開放部２４ａという）は、開放されている。 FIG. 7 shows a schematic configuration of the movable side guide member 2a. As shown in FIGS. 2, 5 and 7, the movable side guide member 2a is an arc-shaped member along the rotation direction, and is provided on the outer peripheral side of the heat insulating material 32 that covers the outer periphery of the second tubular member 31. Has been done. In the examples shown in FIGS. 4 and 5, the movable side guide member 2a is arranged over substantially the upper half of the second cylinder member 31. The movable side guide member 2a holds the wiring portion 1b (in short, the coil spring 103) along the holding surface 21a and the holding walls 22a and 23a. The holding surface 21a is a curved surface that is concavely curved with a curvature substantially equal to the curvature of the spiral of the metal wire 300 that is spirally wound. The holding wall 22a stands up from the inner peripheral edge of the holding surface 21a, and the holding wall 23a stands up from the outer peripheral edge of the holding surface 21a and faces the holding wall 22a. The peripheral surfaces of the holding walls 22a and 23a are flat surfaces, but may be concavely curved with a curvature substantially equal to the curvature of the spiral of the metal wire 300 wound in a spiral shape. In the movable side guide member 2a, the space surrounded by the holding surface 21a and the holding walls 22a and 23a defines the holding space of the wiring portion 1b. A part of the holding space (a portion facing the fixed side guide member 2b, hereinafter referred to as an open portion 24a) is open.
　可動側ガイド部材２ａの両端には、第２筒部材３１との固定部２５ａ，２６ａが設けられている。固定部２５ａは、可動側ガイド部材２ａの一端を第２筒部材３１に固定し、固定部２６ａは、可動側ガイド部材２ａの他端を第２筒部材３１に固定している。また、固定部２５ａは、配線部１ｂの一端１０３ａを固定している。配線部１ｂの他端１０３ｂは、開放部２４ａから可動側ガイド部材２ａの外に延出している。 Fixing portions 25a and 26a with the second cylinder member 31 are provided at both ends of the movable side guide member 2a. The fixing portion 25a fixes one end of the movable side guide member 2a to the second cylinder member 31, and the fixing portion 26a fixes the other end of the movable side guide member 2a to the second cylinder member 31. Further, the fixing portion 25a fixes one end 103a of the wiring portion 1b. The other end 103b of the wiring portion 1b extends from the opening portion 24a to the outside of the movable side guide member 2a.
　保持面２１ａ、保持壁２２ａ，２３ａには、周方向の数箇所に所定間隔で複数のリブ２７ａが設けられている。リブ２７ａは、回動方向と交差する方向に、保持面２１ａ、保持壁２２ａ，２３ａからそれぞれ起立して連続する突起（条）である。リブ２７ａは、螺旋状に巻回する金属線３００と係合可能とされている。したがって、回動ユニット３０の回動時、リブ２７ａは金属線３００と順次係合し、可動側ガイド部材２ａにおける配線部１ｂ（端的には、コイルスプリング１０３）の滑り止めとしての機能を果たす。図４および図５に示す例において、保持面２１ａは一部に開口２８ａを有しているが、開口２８ａは省略可能である。 A plurality of ribs 27a are provided on the holding surface 21a and the holding walls 22a and 23a at several locations in the circumferential direction at predetermined intervals. The rib 27a is a protrusion (row) that stands up from the holding surface 21a and the holding walls 22a, 23a, respectively, in a direction intersecting the rotation direction. The rib 27a is capable of engaging with the spirally wound metal wire 300. Therefore, when the rotating unit 30 is rotated, the rib 27a sequentially engages with the metal wire 300, and functions as a non-slip for the wiring portion 1b (in short, the coil spring 103) in the movable side guide member 2a. In the examples shown in FIGS. 4 and 5, the holding surface 21a has an opening 28a in a part, but the opening 28a can be omitted.
　図８には、固定側ガイド部材２ｂの概略的な構成を示す。上述したように、本実施形態において、固定側ガイド部材２ｂは保持部材１０の一部に備えられ、保持部材１０は固定側ガイド部材２ｂを兼ねて構成されている。図２、図５および図８に示すように、保持部材１０は、回動方向に沿った円環状の部材である。 FIG. 8 shows a schematic configuration of the fixed side guide member 2b. As described above, in the present embodiment, the fixed side guide member 2b is provided in a part of the holding member 10, and the holding member 10 also serves as the fixed side guide member 2b. As shown in FIGS. 2, 5 and 8, the holding member 10 is an annular member along the rotation direction.
　固定側ガイド部材２ｂは、保持部材１０の前面側のほぼ上半分に亘って設けられている。これにより、図４および図５に示すような基準状態において、固定側ガイド部材２ｂは、前方からみて可動側ガイド部材２ａと一部がラップする。すなわち、回動方向への回動ユニット３０の回動可能域において、固定側ガイド部材２ｂは、少なくとも一部が可動側ガイド部材２ａと対向可能に配置されている。図８に示す例において、固定側ガイド部材２ｂは、二つの構造体に分割されているが、連続する一つの構造体であってもよいし、三つ以上の構造体に分割されていてもよい。 The fixed side guide member 2b is provided over substantially the upper half of the front side of the holding member 10. As a result, in the reference state as shown in FIGS. 4 and 5, the fixed side guide member 2b partially wraps with the movable side guide member 2a when viewed from the front. That is, in the rotatable region of the rotating unit 30 in the rotating direction, at least a part of the fixed side guide member 2b is arranged so as to face the movable side guide member 2a. In the example shown in FIG. 8, the fixed side guide member 2b is divided into two structures, but it may be one continuous structure or may be divided into three or more structures. good.
　固定側ガイド部材２ｂは、保持面２１ｂおよび保持壁２２ｂ，２３ｂに沿って配線部１ｂ（端的には、コイルスプリング１０３）を保持する。保持面２１ｂは、平坦面であるが、螺旋状に巻回する金属線３００の螺旋の曲率とほぼ同等の曲率で凹状に湾曲する湾曲面であってもよい。保持壁２２ｂは、保持面２１ｂの内周縁から起立し、保持壁２３ｂは、保持面２１ｂの外周縁から起立して保持壁２２ｂと対向している。保持壁２２ｂ，２３ｂの周面は、平坦面であるが、螺旋状に巻回する金属線３００の螺旋の曲率とほぼ同等の曲率で凹状に湾曲していてもよい。固定側ガイド部材２ｂにおいて、保持面２１ｂと保持壁２２ｂ，２３ｂで囲まれた空間は、配線部１ｂの保持空間を規定する。保持空間の一部（可動側ガイド部材２ａとの対向部であり、以下、開放部２４ｂという）は、開放されている。 The fixed side guide member 2b holds the wiring portion 1b (in short, the coil spring 103) along the holding surface 21b and the holding walls 22b and 23b. The holding surface 21b is a flat surface, but may be a curved surface that is concavely curved with a curvature substantially equal to the curvature of the spiral of the metal wire 300 that is spirally wound. The holding wall 22b stands up from the inner peripheral edge of the holding surface 21b, and the holding wall 23b stands up from the outer peripheral edge of the holding surface 21b and faces the holding wall 22b. The peripheral surfaces of the holding walls 22b and 23b are flat surfaces, but may be concavely curved with a curvature substantially equal to the curvature of the spiral of the metal wire 300 wound in a spiral shape. In the fixed side guide member 2b, the space surrounded by the holding surface 21b and the holding walls 22b and 23b defines the holding space of the wiring portion 1b. A part of the holding space (a portion facing the movable side guide member 2a, hereinafter referred to as an open portion 24b) is open.
　固定側ガイド部材２ｂは、一端側に固定部２５ｂを有している。固定部２５ｂは、配線部１ｂの他端１０３ｂを固定している。配線部１ｂの一端１０３ａは、開放部２４ｂから固定側ガイド部材２ｂの外に延出している。 The fixed side guide member 2b has a fixed portion 25b on one end side. The fixing portion 25b fixes the other end 103b of the wiring portion 1b. One end 103a of the wiring portion 1b extends from the opening portion 24b to the outside of the fixed side guide member 2b.
　保持面２１ｂ、保持壁２２ｂ，２３ｂには、周方向の数箇所に所定間隔で複数のリブ２６ｂが設けられている。リブ２６ｂは、回動方向と交差する方向に、保持面２１ｂ、保持壁２２ｂ，２３ｂからそれぞれ起立して連続する突起（条）である。リブ２６ｂは、螺旋状に巻回する金属線３００と係合可能とされている。したがって、回動ユニット３０の回動時、リブ２６ｂは金属線３００と係合し、可動側ガイド部材２ａにおける配線部１ｂ（端的には、コイルスプリング１０３）の滑り止めとしての機能を果たす。 A plurality of ribs 26b are provided on the holding surface 21b and the holding walls 22b and 23b at several locations in the circumferential direction at predetermined intervals. The rib 26b is a protrusion (strip) that stands up from the holding surface 21b and the holding walls 22b and 23b, respectively, in a direction intersecting the rotation direction. The rib 26b is capable of engaging with the spirally wound metal wire 300. Therefore, when the rotating unit 30 is rotated, the rib 26b engages with the metal wire 300 and functions as a non-slip for the wiring portion 1b (in short, the coil spring 103) in the movable side guide member 2a.
　このように本実施形態によれば、コイルスプリング１０３は、一端１０３ａが可動側ガイド部材２ａに固定され、他端１０３ｂが固定側ガイド部材２ｂに固定されている。したがって、回動ユニット３０が回動すると、コイルスプリング１０３は、回動ユニット３０の回動に応じて弾性変形する。このとき、配線部１ｂがガイド部材１０２（可動側ガイド部材２ａおよび固定側ガイド部材２ｂ）で保持されつつ、自在に屈曲および伸縮し、折返し部１ｃが回動方向に沿って変位する。 As described above, according to the present embodiment, one end 103a of the coil spring 103 is fixed to the movable side guide member 2a, and the other end 103b is fixed to the fixed side guide member 2b. Therefore, when the rotating unit 30 rotates, the coil spring 103 elastically deforms in response to the rotation of the rotating unit 30. At this time, the wiring portion 1b is freely bent and expanded and contracted while being held by the guide member 102 (movable side guide member 2a and fixed side guide member 2b), and the folded portion 1c is displaced along the rotation direction.
　配線部１ｂの屈曲や伸縮、折返し部１ｃの変位に応じて、リード線１ａも配線部１ｂと同等の形態に変化し、折返し部１ｃの位置で折り返される。すなわち、回動ユニット３０が回動した場合であっても、リード線１ａは、配線部１ｂ、つまり螺旋状に巻回された金属線３００によって規定される内部空間に配線され、該内部空間から外れることがない。このため、回動ユニット３０が回動した際、回動ユニット３０と保持部材１０との間でリード線１ａの位置が不定となることを抑止できる。 The lead wire 1a also changes to the same form as the wiring portion 1b according to the bending and expansion / contraction of the wiring portion 1b and the displacement of the folded portion 1c, and is folded back at the position of the folded portion 1c. That is, even when the rotating unit 30 is rotated, the lead wire 1a is wired in the wiring portion 1b, that is, the internal space defined by the spirally wound metal wire 300, and the lead wire 1a is wired from the internal space. It will not come off. Therefore, when the rotating unit 30 rotates, it is possible to prevent the position of the lead wire 1a from becoming indefinite between the rotating unit 30 and the holding member 10.
　また、回動方向に沿って変位する折返し部１ｃの位置でリード線１ａが折り返されるため、リード線１ａの折返し位置、つまり屈曲位置を順次変動させることができる。したがって、リード線１ａの屈曲位置を特定箇所に集中させずに済み、リード線１ａが断線するような不具合を抑制できる。 Further, since the lead wire 1a is folded back at the position of the folded-back portion 1c that is displaced along the rotation direction, the folded-back position of the lead wire 1a, that is, the bending position can be sequentially changed. Therefore, it is not necessary to concentrate the bending position of the lead wire 1a at a specific location, and it is possible to suppress a problem that the lead wire 1a is broken.
　すなわち、回動ユニット３０と保持部材１０との間を繋ぐリード線１ａが両者の間で回動ユニット３０の回動時に暴れることを抑制し、リード線１ａを所望の範囲内に所望の形態で配線することができる。このため、リード線１ａの保護を適切に図ることができる。 That is, it is possible to prevent the lead wire 1a connecting between the rotating unit 30 and the holding member 10 from violently violently during the rotation of the rotating unit 30 between the two, and to keep the lead wire 1a within a desired range in a desired form. Can be wired. Therefore, the lead wire 1a can be appropriately protected.
　加えて、可動側ガイド部材２ａにはリブ２７ａが設けられ、固定側ガイド部材２ｂにはリブ２６ｂが設けられている。したがって、回動ユニット３０が回動した際、配線部１ｂが屈曲や伸縮した場合であっても、リブ２７ａ，２６ｂを金属線３００と順次係合させることができる。これにより、ガイド部材１０２（可動側ガイド部材２ａおよび固定側ガイド部材２ｂ）において配線部１ｂの滑り止めを図ることができ、配線部１ｂをガイド部材２ａ，２ｂで確実に保持できる。このため、例えば回動ユニット３０が回動した際、コイルスプリング１０３のガイド部材２ａ，２ｂからの脱落を抑制できる。 In addition, the movable side guide member 2a is provided with a rib 27a, and the fixed side guide member 2b is provided with a rib 26b. Therefore, when the rotating unit 30 rotates, the ribs 27a and 26b can be sequentially engaged with the metal wire 300 even when the wiring portion 1b is bent or expanded and contracted. As a result, the guide member 102 (movable side guide member 2a and fixed side guide member 2b) can prevent the wiring portion 1b from slipping, and the wiring portion 1b can be reliably held by the guide members 2a and 2b. Therefore, for example, when the rotating unit 30 rotates, it is possible to prevent the coil spring 103 from falling off from the guide members 2a and 2b.
　さらに、コイルスプリング１０３およびガイド部材２ａ，２ｂで配線保護構造１００を構成することで、配線保護構造１００を部品点数の少ない簡素な構成とすることができ、コストも抑制できる。 Further, by configuring the wiring protection structure 100 with the coil spring 103 and the guide members 2a and 2b, the wiring protection structure 100 can be made into a simple configuration with a small number of parts, and the cost can be suppressed.
　上述したように、本実施形態の配線保護構造１００では保護部材１０１をコイルスプリング１０３としているが、保護部材１０１はコイルスプリング１０３に限定されない。以下、保護部材１０１の別形態を第２の実施形
態として説明する。 As described above, in the wiring protection structure 100 of the present embodiment, the protection member 101 is a coil spring 103, but the protection member 101 is not limited to the coil spring 103. Hereinafter, another embodiment of the protective member 101 will be described as a second embodiment.

In the example shown in FIG. 9, these frames 400 have the same shape. However, a chain may be formed by connecting several types of pieces having different shapes. In the present embodiment, the top 400 is made of resin, but may be made of metal or the like.

　第１片部４０１は貫通孔４０１ｂを有し、第３片部４０３は貫通孔４０１ｂと同一径の貫通孔４０３ｂを有している。図１１に示すように、貫通孔４０１ｂ，４０３ｂは、中心同士を結ぶ直線Ｌ１が中心点Ｃを通るようにそれぞれ配置されている。中心点Ｃは、軸ＡＸ上の任意の点である。第２片部４０２は軸４０２ｂを有し、第４片部４０４は軸４０２ｂと同一径の軸４０４ｂを有している。図１１に示すように、軸４０２ｂ，４０４ｂは、中心同士を結ぶ直線Ｌ２が中心点Ｃを通るようにそれぞれ配置されている。また、軸４０２ｂ，４０４ｂは、貫通孔４０１ｂ，４０３ｂに挿通されて回動可能に支持されるように、貫通孔４０１ｂ，４０３ｂの孔径よりもわずかに小さな軸径とされている。軸４０２ｂ，４０４ｂの長さ（高さ）は、各片部４０２，４０４のほぼ肉厚分であり、段差部４０１ａ，４０３ａの段差（高さ）とほぼ一致している。 The first piece 401 has a through hole 401b, and the third piece 403 has a through hole 403b having the same diameter as the through hole 401b. As shown in FIG. 11, the through holes 401b and 403b are arranged so that the straight line L1 connecting the centers passes through the center point C, respectively. The center point C is an arbitrary point on the axis AX. The second piece 402 has a shaft 402b, and the fourth piece 404 has a shaft 404b having the same diameter as the shaft 402b. As shown in FIG. 11, the axes 402b and 404b are arranged so that the straight line L2 connecting the centers passes through the center point C, respectively. Further, the shafts 402b and 404b have a shaft diameter slightly smaller than the hole diameters of the through holes 401b and 403b so as to be inserted through the through holes 401b and 403b and rotatably supported. The length (height) of the shafts 402b and 404b is substantially the thickness of each piece 402 and 404, and is substantially the same as the step (height) of the step portions 401a and 403a.
　第１片部４０１は、段差部４０１ａとは反対側の端部の一隅に湾曲部４０１ｃを有している。第３片部４０３は、段差部４０３ａとは反対側の端部の一隅に湾曲部４０３ｃを有している。湾曲部４０１ｃ，４０３ｃは、同一の曲率で、貫通孔４０１ｂ，４０３ｂの周縁に沿って湾曲している。第２片部４０２は、段差部４０２ａとは反対側の端部に湾曲部４０２ｃを有している。第４片部４０４は、段差部４０４ａとは反対側の端部に湾曲部４０４ｃを有している。湾曲部４０２ｃ，４０４ｃは、同一の曲率で、軸４０２ｂ，４０４ｂの周面に沿って湾曲している。 The first piece 401 has a curved portion 401c at one corner of an end portion opposite to the step portion 401a. The third piece 403 has a curved portion 403c at one corner of an end portion opposite to the step portion 403a. The curved portions 401c and 403c are curved along the peripheral edges of the through holes 401b and 403b with the same curvature. The second piece portion 402 has a curved portion 402c at an end portion opposite to the step portion 402a. The fourth piece 404 has a curved portion 404c at an end opposite to the stepped portion 404a. The curved portions 402c and 404c are curved along the peripheral surfaces of the shafts 402b and 404b with the same curvature.
　このような構成をなすコマ４００は、隣り合うもの同士が順に軸４０２ｂを貫通孔４０１ｂに挿通させるとともに、軸４０４ｂを貫通孔４０３ｂに挿通させて、図１２に示すように連結される。複数のコマ４００が連結されることで、一連のチェーン１０４が構成される。チェーン１０４を構成するコマ４００ごとに貫通孔４０１ｂ，４０３ｂの中心同士を結ぶ各直線Ｌ１、および軸４０２ｂ，４０４ｂの中心同士を結ぶ各直線Ｌ２は、すべて中心点Ｃで交差する。これにより、チェーン１０４は、回動方向に沿った円弧状に一端１０４ａから他端１０４ｂまで連続して構成される。チェーン１０４の一端１０４ａは第２筒部材３１に固定され、他端１０４ｂは保持部材１０に固定されている。固定方法は、ねじ止め、ブラケットなどの固定具を介した固定など任意の方法で構わない。 The pieces 400 having such a configuration are connected as shown in FIG. 12 by having adjacent ones insert the shaft 402b through the through hole 401b and the shaft 404b through the through hole 403b in order. A series of chains 104 are formed by connecting a plurality of frames 400. Each straight line L1 connecting the centers of the through holes 401b and 403b and each straight line L2 connecting the centers of the shafts 402b and 404b intersect at the center point C for each piece 400 constituting the chain 104. As a result, the chain 104 is continuously formed from one end 104a to the other end 104b in an arc shape along the rotation direction. One end 104a of the chain 104 is fixed to the second cylinder member 31, and the other end 104b is fixed to the holding member 10. The fixing method may be any method such as screwing or fixing via a fixing tool such as a bracket.
　複数のコマ４００が連結されることで、各コマ４００の七つの片部４０１～４０７で規定される内部空間が連続して形成される。チェーン１０４では、複数のコマ４００が連結されて一連の内部空間を形成する部分、端的には連結された複数のコマ４００が配線部１ｂに相当する。リード線１ａは、配線部１ｂ、つまり連結された複数のコマ４００（換言すればチェーン１０４）の内部空間（配線空間）を通して配線される。 By connecting the plurality of frames 400, the internal space defined by the seven pieces 401 to 407 of each frame 400 is continuously formed. In the chain 104, a portion in which a plurality of pieces 400 are connected to form a series of internal spaces, in short, a plurality of connected pieces 400 correspond to a wiring portion 1b. The lead wire 1a is wired through the wiring portion 1b, that is, the internal space (wiring space) of the plurality of connected frames 400 (in other words, the chain 104).
　図１３および図１４には、コマ４００の連結態様を示す。図示例では、一方のコマ４００ａの貫通孔４０３ｂ（４０１ｂ）に他方のコマ４００ｂの軸４０４ｂ（４０２ｂ）が挿通されている。これにより、コマ４００ａ，４００ｂは、軸４０４ｂ（４０２ｂ）を中心として相対的に回動する。図１３は、連結された二つのコマ４００ａ，４００ｂの回動角度が最小である態様を概略的に示す図である。図１４は、連結された二つのコマ４００ａ，４００ｂの回動角度が最大である態様を概略的に示す図である。一例として、回動角度は、連結された二つのコマ４００ａ，４００ｂにおいて、一方のコマ４００ａに対して他方のコマ４００ｂが傾斜する角度（図１４に示すような角度θ）である。 13 and 14 show the connection mode of the frame 400. In the illustrated example, the shaft 404b (402b) of the other piece 400b is inserted into the through hole 403b (401b) of the one piece 400a. As a result, the frames 400a and 400b rotate relatively around the shaft 404b (402b). FIG. 13 is a diagram schematically showing an embodiment in which the rotation angles of the two connected frames 400a and 400b are the minimum. FIG. 14 is a diagram schematically showing an embodiment in which the rotation angles of the two connected frames 400a and 400b are maximum. As an example, the rotation angle is an angle (angle θ as shown in FIG. 14) in which the other frame 400b is tilted with respect to one frame 400a in the two connected frames 400a and 400b.
　すなわち、二つのコマ４００ａ，４００ｂは、図１３に示す回動角度最小位置と図１４に示す回動角度最大位置との間で相対的に回動する。換言すれば、二つのコマ４００ａ，４００ｂの回動可能域は、図１３に示す最小回動角度（θがほぼ０°）から図１４に示す最大可動角度（θがほぼ９０°）の間とされている。湾曲部４０３ｃ（４０１ｃ）を有しているため、二つのコマ４００ａ，４００ｂは、コマ４００ａの端部４０３ｄ（４０１ｄ）とコマ４００ｂの段差部４０４ａ（４０２ａ）とを干渉させずに回動可能域で回動する。また、湾曲部４０４ｃ（４０２ｃ）を有しているため、二つのコマ４００ａ，４００ｂは、コマ４００ａの段差部４０３ａ（４０１ａ）とコマ４００ｂの第４片部４０４（第２片部４０２）とを干渉させずに回動可能域で回動する。 That is, the two frames 400a and 400b rotate relatively between the minimum rotation angle position shown in FIG. 13 and the maximum rotation angle position shown in FIG. In other words, the rotatable range of the two frames 400a and 400b is between the minimum rotation angle (θ is approximately 0 °) shown in FIG. 13 and the maximum movable angle (θ is approximately 90 °) shown in FIG. Has been done. Since the curved portion 403c (401c) is provided, the two frames 400a and 400b can rotate without interfering with the end portion 403d (401d) of the frame 400a and the stepped portion 404a (402a) of the frame 400b. Rotate with. Further, since the curved portion 404c (402c) is provided, the two frames 400a and 400b have a stepped portion 403a (401a) of the frame 400a and a fourth piece portion 404 (second piece portion 402) of the frame 400b. It rotates in the rotatable range without interfering with it.
　図１３に示す態様では、コマ４００ａの端部４０３ｄ（４０１ｄ）とコマ４００ｂの段差部４０４ａ（４０２ａ）とが干渉し、それ以上のコマ４００ａ，４００ｂの回動を阻害する。端部４０３ｄ（４０１ｄ）は、第３片部４０３（第１片部４０１）において段差部４０３ａ（４０１ａ）とは反対側に位置し、湾曲部４０３ｃ（４０１ａ）を有する端部である。 In the aspect shown in FIG. 13, the end portion 403d (401d) of the frame 400a and the stepped portion 404a (402a) of the frame 400b interfere with each other, and further rotation of the frames 400a and 400b is hindered. The end portion 403d (401d) is an end portion of the third piece portion 403 (first piece portion 401) that is located on the opposite side of the step portion 403a (401a) and has a curved portion 403c (401a).
　これに対し、図１４に示す態様では、コマ４００ａの側部４０３ｅ（４０１ｅ）とコマ４００ｂの段差部４０４ａ（４０２ａ）とが干渉し、それ以上のコマ４００ａ，４００ｂの回動を阻害する。側部４０３ｅ（４０１ｅ）は、第３片部４０３（第１片部４０１）の二つの側部のうち、湾曲部４０３ｃ（４０１ａ）と連続する側部である。 On the other hand, in the aspect shown in FIG. 14, the side portions 403e (401e) of the frame 400a and the stepped portion 404a (402a) of the frame 400b interfere with each other, and further rotation of the frames 400a and 400b is hindered. The side portion 403e (401e) is a side portion continuous with the curved portion 403c (401a) of the two side portions of the third piece portion 403 (first piece portion 401).
　すなわち、端部４０３ｄ（４０１ｄ）、側部４０３ｅ（４０１ｅ）、および段差部４０４ａ（４０２ａ）は、隣り合うコマ４００ａ，４００ｂの相対的な回動を回動可能域に制限する規制部である。 That is, the end portion 403d (401d), the side portion 403e (401e), and the step portion 404a (402a) are regulating portions that limit the relative rotation of the adjacent frames 400a and 400b to the rotatable range.
　このように本実施形態によれば、連結されて隣り合う二つのコマ４００ａ，４００ｂが軸４０４ｂ（４０２ｂ）を中心として相対的に回動するため、コマ４００ａ，４００ｂの内部空間（配線部１ｂの一部）は、これらの回動可能域の範囲で形態が変化する。すなわち、複数のコマ４００が連結されて構成されるチェーン１０４の配線部１ｂは、隣り合うコマ４００同士の回動可能域が順に連続する範囲で形態が変化する。このため、回動ユニット３０が回動すると、チェーン１０４の折返し部１ｃが回動方向に沿って変位する。換言すれば、配線部１ｂの折返し位置が回動方向に沿って変化する。このとき、配線部１ｂの折返し位置、つまり折返し部１ｃの変位に対応して、リード線１ａも配線部１ｂ（端的には、チェーン１０４）と同等の形態に変化し、折返し部１ｃの位置で折り返される。 As described above, according to the present embodiment, the two frames 400a and 400b that are connected and adjacent to each other rotate relative to each other about the shaft 404b (402b), so that the internal space of the frames 400a and 400b (wiring portion 1b). (Part) changes its form within the range of these rotatable ranges. That is, the form of the wiring portion 1b of the chain 104 formed by connecting the plurality of pieces 400 changes in a range in which the rotatable regions of the adjacent pieces 400 are sequentially continuous. Therefore, when the rotating unit 30 rotates, the folded-back portion 1c of the chain 104 is displaced along the rotation direction. In other words, the folded position of the wiring portion 1b changes along the rotation direction. At this time, the lead wire 1a also changes to the same form as the wiring portion 1b (in short, the chain 104) in response to the folding position of the wiring portion 1b, that is, the displacement of the folding portion 1c, and at the position of the folding portion 1c. It will be folded back.
　したがって、回動ユニット３０が回動した場合であっても、リード線１ａは配線部１ｂ、つまり連結された複数のコマ４００の内部空間に配線されるため、該内部空間から外れることがない。このため、回動ユニット３０が回動した際、回動ユニット３０と保持部材１０との間でリード線１ａの位置が不定となることを抑止できる。 Therefore, even when the rotating unit 30 rotates, the lead wire 1a is wired in the wiring portion 1b, that is, the internal space of the plurality of connected tops 400, so that the lead wire 1a does not deviate from the internal space. Therefore, when the rotating unit 30 rotates, it is possible to prevent the position of the lead wire 1a from becoming indefinite between the rotating unit 30 and the holding member 10.
　その際、配線部１ｂは、隣り合うコマ４００同士の回動可能域が順に連続する範囲内で変形可能とされている。したがって、配線部１ｂ、端的にはチェーン１０４の変形可能域をかかる範囲内に制限できる。これにより、リード線１ａの暴れ（反発）をチェーン１０４の変形可能域内に止めることができる。すなわち、回動ユニット３０と保持部材１０との間を繋ぐリード線１ａが両者の間で回動ユニット３０の回動時に暴れることを抑制し、リード線１ａを所望の範囲内に所望の形態で配線することができる。このため、リード線１ａの保護を適切に図ることができる。 At that time, the wiring portion 1b is deformable within a range in which the rotatable areas of adjacent frames 400 are sequentially continuous. Therefore, the deformable range of the wiring portion 1b, that is, the chain 104, can be limited within such a range. As a result, the runaway (repulsion) of the lead wire 1a can be stopped within the deformable range of the chain 104. That is, it is possible to prevent the lead wire 1a connecting between the rotating unit 30 and the holding member 10 from violently violently during the rotation of the rotating unit 30 between the two, and to keep the lead wire 1a within a desired range in a desired form. Can be wired. Therefore, the lead wire 1a can be appropriately protected.
　加えて、チェーン１０４は、同一形状の複数のコマ４００を連結させて構成されている。このため、例えば異なる数種類のコマを連結してチェーンが構成されている場合と比べ、金型費用などを低減させることができ、チェーン１０４の製造コストも抑制できる。 In addition, the chain 104 is configured by connecting a plurality of frames 400 having the same shape. Therefore, as compared with the case where a chain is formed by connecting several different types of frames, for example, the mold cost and the like can be reduced, and the manufacturing cost of the chain 104 can also be suppressed.
　以上、本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。 Although some embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention.
